Python Mcp

Files.com MCP Server

The files-com-mcp Python package lets your AI application interact with Files.com. It is for local use only and supports STDIO only: your MCP client starts the package as a subprocess on the same machine.

For MCP connections over a network, use the Files.com hosted MCP service.

Set FILES_COM_API_KEY in the environment your client passes to the subprocess. The local package makes outbound requests to the Files.com API to perform site operations.

Files.com is the cloud-native, next-gen MFT, SFTP, and secure file-sharing platform that replaces brittle legacy servers with one always-on, secure fabric. Automate mission-critical file flows—across any cloud, protocol, or partner—while supporting human collaboration and eliminating manual work.

With universal SFTP, AS2, HTTPS, and 50+ native connectors backed by military-grade encryption, Files.com unifies governance, visibility, and compliance in a single pane of glass.

Introduction

The Files.com Python MCP package lets Claude Desktop and other local MCP clients upload and download files, query folders, manage users, and run automations on your Files.com site. It uses the permissions of your API key, and its actions are logged like those of any other API client.

The Python package supports local use over STDIO (standard input and output) only. Your MCP client starts it on the same machine and communicates directly with that process, without a network listener. The package still needs outbound access to the Files.com API.

What MCP Is

The Model Context Protocol (MCP) is a standard interface through which a Large Language Model calls real APIs as part of its work. An MCP server hands the model a set of tools, and each Files.com tool is an authenticated operation in your site. With the server connected, the model can:

• Transfer files between cloud and on-premises systems
• Query folders and file metadata
• Create and manage users
• Automate workflows such as archiving or sharing

Common Use Cases

Assistants for operations teams. An internal chatbot fetches or archives files on request.

Automated workflows. An agent reacts to an incoming support request, then retrieves or uploads the files the case needs.

Developer copilots. A development-focused LLM creates users, provisions folders, or reads files while debugging.

Local vs. Hosted MCP

Use the local Python package with clients that launch STDIO servers, including Claude Desktop.

For clients that connect to MCP over a network, use the Files.com hosted MCP service. Files.com operates the server, so you do not need to install the Python package. Running the Python package as an HTTP or SSE service is unsupported, including during development.

Install uv, register uvx files-com-mcp as an MCP server in your LLM client, and give it a Files.com API key in the FILES_COM_API_KEY environment variable.

https://pypi.org/project/files-com-mcp/

Installation

The files-com-mcp Python package lets your MCP client call the Files.com API through a process running on your machine. It supports local use over STDIO (standard input and output) only. For clients that connect to MCP over a network, use the Files.com hosted MCP service.

Requirements

Your MCP client must be able to start a local STDIO server. Your machine needs outbound access to the Files.com API.

The examples run the server with uvx, which is part of uv. It runs a Python tool in an isolated environment of its own, so there is nothing to install or configure by hand beyond uv itself. Install uv first.

Registering The Server

Set your client's local STDIO server command to uvx with files-com-mcp as the argument. uvx downloads the package on first use and starts it each time your client launches the server.

The Claude Desktop configuration shows these settings in JSON. For other clients, follow their instructions for adding a local STDIO server.

Authentication

The server authenticates to Files.com with an API key, read from the FILES_COM_API_KEY environment variable that your client passes to it. The model can do exactly what the key's user can do, so create a key for this purpose with the permissions the agent needs and no more.

Restricting Local File Transfers

Optionally set FILES_COM_LOCAL_ROOT in your client's server environment to an existing absolute directory path, such as /home/user/Documents. Uploads can only read files within that directory and its children, and downloads can only write there. When the variable is omitted or empty, transfers can use any local path accessible to the server.

The server resolves .. and symbolic links before checking each path. Relative transfer paths are resolved from the server's working directory and must still stay inside the configured directory. A download can create a new file in an existing directory within the boundary. A nonempty value must name an existing absolute directory; otherwise, the server will not start.

This setting applies to local transfer paths. Files.com paths continue to follow the API key's permissions.

uvx files-com-mcp

FILES_COM_API_KEY=your-api-key uvx files-com-mcp

FILES_COM_API_KEY=your-api-key FILES_COM_LOCAL_ROOT=/home/user/Documents uvx files-com-mcp

Using With Claude

Claude Desktop uses the Files.com Python MCP package to call the Files.com API from your machine. This setup supports local use over STDIO (standard input and output) only. For a network connection to MCP, use the Files.com hosted MCP service.

Claude Desktop reads its MCP servers from claude_desktop_config.json. Add the entry on the right under mcpServers, replace the FILES_COM_API_KEY value with a Files.com API key, and restart Claude Desktop. The MCP quickstart shows where the file lives on each operating system, walking through the same steps for another server.

The entry starts the server with uvx, so uv has to be installed first; see Installation.

Once Claude has restarted, the Files.com tools appear in its tool list. Tools lists them by category and explains why it pays to enable only the ones a task needs.

To restrict local uploads and downloads, optionally add "FILES_COM_LOCAL_ROOT": "/home/user/Documents" alongside FILES_COM_API_KEY in the env object, using an existing absolute directory on your machine. Restart Claude Desktop after changing it. See Restricting Local File Transfers for details.

Tools

The Files.com MCP server exposes the tools below, grouped by category: files, folders, sharing, users, logs, automations and the other Files.com resources. Each tool is one operation in your site, run with the permissions of the API key the server holds.

Keep The Toolset Focused

A model picks the right tool more reliably from a short list. If the LLM uses Files.com tools inconsistently, it is most likely choosing among too many. Most clients let you enable and disable an MCP server's tools one by one; enable only the ones the agent's task needs.

Authentication

The Files.com MCP uses API key authentication.

Authenticate with an API Key

Authenticating with an API key is the recommended authentication method for most scenarios, and is the method used in the examples on this site.

To use an API Key, first generate an API key from the web interface or via the API or an SDK.

Note that when using a user-specific API key, if the user is an administrator, you will have full access to the entire API. If the user is not an administrator, you will only be able to access files that user can access, and no access will be granted to site administration functions in the API.

Don't forget to replace the placeholder, YOUR_API_KEY, with your actual API key.

Sort and Filter

Several of the Files.com API resources have list operations that return multiple instances of the resource. The List operations can be sorted and filtered.

Sorting

To sort the returned data, pass in the sort_by method argument.

Each resource supports a unique set of valid sort fields and can only be sorted by one field at a time.

Special note about the List Folder Endpoint

For historical reasons, and to maintain compatibility with a variety of other cloud-based MFT and EFSS services, Folders will always be listed before Files when listing a Folder. This applies regardless of the sorting parameters you provide. These will be used, after the initial sort application of Folders before Files.

Filtering

Filters apply selection criteria to the underlying query that returns the results. They can be applied individually or combined with other filters, and the resulting data can be sorted by a single field.

Each resource supports a unique set of valid filter fields, filter combinations, and combinations of filters and sort fields.

Filter Types

Filter	Type	Description
filter	Exact	Find resources that have an exact field value match to a passed in value. (i.e., FIELD_VALUE = PASS_IN_VALUE).
filter_prefix	Pattern	Find resources where the specified field is prefixed by the supplied value. This is applicable to values that are strings.
filter_gt	Range	Find resources that have a field value that is greater than the passed in value. (i.e., FIELD_VALUE > PASS_IN_VALUE).
filter_gteq	Range	Find resources that have a field value that is greater than or equal to the passed in value. (i.e., FIELD_VALUE >= PASS_IN_VALUE).
filter_lt	Range	Find resources that have a field value that is less than the passed in value. (i.e., FIELD_VALUE < PASS_IN_VALUE).
filter_lteq	Range	Find resources that have a field value that is less than or equal to the passed in value. (i.e., FIELD_VALUE <= PASS_IN_VALUE).

Paths

Files.com preserves the spelling of file and folder paths while comparing them using shared case and Unicode rules. Use the SDK comparison helpers when matching paths locally.

Capitalization

Files.com uses case-insensitive path matching based on its fixed Unicode comparison map.

For example, the following paths have the same comparison key:

Path Variant	Comparison Key
Documents/Reports/Q1.pdf	documents/reports/q1.pdf
documents/reports/q1.PDF	documents/reports/q1.pdf
DOCUMENTS/REPORTS/Q1.PDF	documents/reports/q1.pdf

This behavior applies across:

• API requests
• Folder and file lookup operations
• Automations and workflows

See also: Case Sensitivity Documentation

Slashes

Use / between folder and file names, without leading or trailing slashes. SDK normalization helpers convert backslashes to /, remove duplicate separators, and discard exact . and .. components. Discarding .. leaves the preceding folder name intact.

Input	Normalized path
folder/subfolder/file.txt	folder/subfolder/file.txt
/folder/subfolder/file.txt	folder/subfolder/file.txt
folder/subfolder/file.txt/	folder/subfolder/file.txt
//folder//file.txt	folder/file.txt
folder/../file.txt	folder/file.txt

Unicode and Path Comparison

Files.com compares paths using a fixed mapping shared by the server and SDKs. It treats case and many accent differences as equivalent: Résumé.txt and resume.txt identify the same file, as do q followed by a combining acute accent and q. The mapping also handles other equivalences, such as Hiragana and Katakana. Lowercasing or applying a standard Unicode normalization form alone does not reproduce these rules.

SDK comparison helpers normalize path separators and dot segments, then apply the bundled versioned comparison map. The shared examples give exact comparison results for integrations that implement their own matching. The map uses hexadecimal Unicode scalar values as keys: a missing entry preserves the character, an empty replacement removes it, and other replacements may contain several characters. Apply each replacement once without normalizing or lowercasing the result again.

Use comparison results only for matching. Send the original path spelling in API requests and preserve it for display and local filenames; comparison results can have a different spelling or length.

Trailing whitespace is significant for comparison. report.txt and report.txt are different file paths, and SDK helpers preserve spaces, tabs, and newlines. Folder names cannot end in whitespace. See Unicode Normalization for the complete path rules.

Workspaces

A Workspace groups files, users, groups, Partners, integrations, and workflows within a Files.com Site. An integration can provision a Workspace for a department or project and delegate its operation to a team without making that team Site Administrators. Every Site has a Default Workspace, with ID 0; additional Workspaces have their own IDs and root folders.

Account membership, request context, and permission grants serve different purposes. Creating an account in a Workspace determines where it belongs. Selecting a Workspace determines which resources a request operates on. A permission grant determines what the caller can do there. Selecting a Workspace never grants access to it.

Accounts and Administrative Access

A user's or group's workspace_id identifies the Workspace the account belongs to. Accounts belonging to a Custom Workspace stay within it. Default Workspace users and groups can receive permissions in one or more Custom Workspaces while keeping their existing accounts in Workspace 0.

Account	Workspace Administrator assignment	Scope
User belonging to a Custom Workspace	Set the user's workspace_admin to true.	That user's own Custom Workspace.
Default Workspace user	Create an admin Permission for the user on a Custom Workspace's root folder.	Each Custom Workspace with a root grant.
Default Workspace group	Create an admin Permission for the group on a Custom Workspace's root folder.	Every member inherits administration of each Workspace with a root grant.

workspace_admin is not a summary of a user's effective administrative access. A Default Workspace user can administer a Custom Workspace through a direct or group root grant while their workspace_admin remains false. Groups have no workspace_admin field. See Users and Groups for account fields.

An admin grant on the Custom Workspace root provides full Workspace Administrator authority over its files, users, groups, Partners, workflows, and integrations. An admin grant on a subfolder provides Folder Admin authority over that folder and its descendants; it does not provide Workspace administration. Other permission levels provide their corresponding folder access without Workspace administration. Permissions defines the levels.

Site Administrators manage cross-Workspace assignments to Default Workspace accounts. Workspace Administrators manage accounts and permissions within their own scope. Site Administrators retain access to every Workspace; adding a Workspace grant does not narrow Site Administrator authority. The product documentation explains the administrator's operational scope and site-wide controls.

Request Context and API Keys

You can include the X-Files-Workspace-Id REST header to select a Workspace for a request. SDK request options and CLI configuration send that same selection. When a Workspace is selected, Workspace-scoped resources are listed, created, and changed within that context, and ordinary paths are relative to its root.

A resource's workspace_id request field describes the resource's Workspace membership. It is separate from the SDK's Workspace request option or REST header. Creating a Workspace-scoped resource in a Custom Workspace defaults its workspace_id to the selected Workspace; a mismatching membership value is rejected with not-authorized/insufficient-permission-for-params.

Selecting another Workspace with an API key requires a Full Access key created in the Default Workspace. A user key follows that user's current access, including group permissions. A site-wide Full Access key created in the Default Workspace has Site Administrator authority in every Workspace. A Files Only key stays in its creation Workspace, even if its user has cross-Workspace access. Any key created in a Custom Workspace stays within that Workspace. Selecting another context with these confined keys is rejected with bad-request/invalid-workspace-id-header.

An account belonging to a Custom Workspace is scoped there when it authenticates normally. For a Default Workspace user, explicitly select the intended Workspace for an integration rather than relying on an interactive login preference. API Keys and Authentication cover credentials.

The adjacent request uses the member's own Default Workspace Full Access user key to list the root of Workspace 123, after access has been assigned.

curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/folders/' \
  -H 'X-FilesAPI-Key: YOUR_MEMBER_API_KEY' \
  -H 'X-Files-Workspace-Id: 123'

Delegating a Workspace to an Existing Group

An operations team already represented by a Default Workspace group can administer a Custom Workspace through one root Permission. The group and its members stay in the Default Workspace, so the same team can receive different access in other Workspaces.

First retrieve the target Workspace and Group IDs as a Site Administrator in Workspace 0. The examples use Workspace 123, group 456, and member user 789; replace them with your own IDs. Confirm that the group belongs to Workspace 0 and that the intended user is a member.

Create the Permission using a Default Workspace Full Access site-wide key or a Full Access user key belonging to a Site Administrator. Keep the request context at 0 and use the qualified root path _/Workspaces/123. Set group_id to the group's ID, permission to admin, and recursive to true. Save the returned Permission id for later removal. For an individual Default Workspace user, use user_id instead of group_id.

For a Default Workspace group, a Site Administrator can also select Workspace 123 and use an empty path to grant access to its root. The qualified path in Workspace 0 works for both Default Workspace users and groups and keeps the account scope and target Workspace explicit. Appending a subfolder to the path would grant Folder Admin access instead of Workspace Administrator authority.

After the grant, run the request-context example above with the member's own credential and Workspace 123 selected. That member can work with the Workspace's files and perform Workspace Administrator operations, such as managing its users, Partners, and integrations. A Site Administrator's successful request does not establish that the member has the intended access.

curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/workspaces' \
  -H 'X-FilesAPI-Key: YOUR_SITE_ADMIN_API_KEY' \
  -H 'X-Files-Workspace-Id: 0'
curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/groups' \
  -H 'X-FilesAPI-Key: YOUR_SITE_ADMIN_API_KEY' \
  -H 'X-Files-Workspace-Id: 0'

curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/permissions' \
  -X POST \
  -H 'X-FilesAPI-Key: YOUR_SITE_ADMIN_API_KEY' \
  -H 'X-Files-Workspace-Id: 0' \
  -H 'Content-Type: application/json' \
  -d '{"path":"_/Workspaces/123","group_id":456,"permission":"admin","recursive":true}'

Permission Inspection and Removal

List the member's Permissions with user_id and include_groups=true to include grants inherited through group membership. Listing only direct user grants can miss the Permission that provides Workspace administration. In Workspace 0, the Custom Workspace root appears as _/Workspaces/123; in Workspace 123, paths are relative to that root. Inspect the root path and permission=admin, rather than treating the user's workspace_admin field as their effective administrative access.

Permission lists show individual grants, rather than a single flag for effective administrative access. Membership in several groups combines their access. A Permission using group_ids instead of group_id requires membership in all the specified groups; it is not a shorthand for assigning the same grant to several independent groups.

Removing a member ends access received through that group. Deleting the root Permission ends the group's Workspace Administrator grant for every member. These changes leave independent direct and other group grants in place, so review all applicable grants when withdrawing access. Default Workspace user API keys follow those permission changes without being recreated.

Group membership maintained through SCIM follows the same rule. A Group Admin allowed to add members can give those users the group's existing Workspace Administrator access. Choose who manages the group with that authority in mind.

Delete the Permission by its returned id as the Site Administrator in Workspace 0. The removal examples use Permission ID 9001; replace it with the ID returned by your create request. Permissions are created and deleted, rather than updated in place. If narrower folder access is still needed, assign it explicitly; deleting a broad grant does not restore narrower grants it previously replaced.

curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/permissions?user_id=789&include_groups=true' \
  -H 'X-FilesAPI-Key: YOUR_SITE_ADMIN_API_KEY' \
  -H 'X-Files-Workspace-Id: 0'
curl 'https://YOUR_SUBDOMAIN.files.com/api/rest/v1/permissions/9001' \
  -X DELETE \
  -H 'X-FilesAPI-Key: YOUR_SITE_ADMIN_API_KEY' \
  -H 'X-Files-Workspace-Id: 0'

Foreign Language Support

The Files.com MCP will soon be updated to support localized responses by using a configuration method. When available, it can be used to guide the API in selecting a preferred language for applicable response content.

Language support currently applies to select human-facing fields only, such as notification messages and error descriptions.

If the specified language is not supported or the value is omitted, the API defaults to English.

Errors

Mock Server

Files.com publishes a Files.com API server, which is useful for testing your use of the Files.com SDKs and other direct integrations against the Files.com API in an integration test environment.

It is a Ruby app that operates as a minimal server for the purpose of testing basic network operations and JSON encoding for your SDK or API client. It does not maintain state and it does not deeply inspect your submissions for correctness.

Eventually we will add more features intended for integration testing, such as the ability to intentionally provoke errors.

Download the server as a Docker image via Docker Hub.

The Source Code is also available on GitHub.

A README is available on the GitHub link.

Development

Run the Python MCP package locally over STDIO when developing or modifying tools. Upload and Download tools rely on the file system where the MCP is running. For network connections, use the Files.com hosted MCP service.

To test LLM tools we recommend a popular command-line program called inspector. This will start a WebUI on a local port, the output of the command will give you the link to the inspector GUI. Ex: http://127.0.0.1:6274
