SRG+

srgplus-mcp

mcp-name: io.github.srgplus/srgplus-mcp

MCP server for SRG+ — lets Claude (and any MCP-aware agent) manage hubs, channels, content, assets, users, and workspaces through the SRG+ API.

Two ways to run it:

• Hosted HTTP (recommended for production / claude.ai web / Cursor / Cline) — single endpoint, header-based auth, multi-tenant
• Local stdio (for desktop dev / offline) — single user, env-var auth, runs as a child process of the agent

Both modes share the same tools and the same SDK underneath — you pick the transport that fits your client.

Hosted HTTP

Run the server

pip install 'srgplus-mcp[server]'
srgplus-mcp-serve   # listens on $PORT (default 8090)

Or in Docker:

docker build -t srgplus-mcp .
docker run -p 8090:8090 srgplus-mcp

Health check:

curl http://localhost:8090/health

Connect from Claude / Cursor / any MCP client

{
  "mcpServers": {
    "srgplus": {
      "url": "http://localhost:8090/mcp",
      "headers": { "X-API-Key": "srgplus_your_key_here" }
    }
  }
}

Or use Authorization: Bearer srgplus_... instead of X-API-Key — both work.

For a hosted public endpoint pointed at your SRG+ workspace, the URL becomes https://mcp.srgplus.com/mcp (rolling out — see SRGDEV-8 follow-ups for the deploy plan).

OAuth (claude.ai web, Connectors Gallery, ChatGPT Apps)

For browser-based clients that require OAuth 2.1 (DCR + PKCE):

1. In claude.ai → Settings → Connectors → Add custom connector
2. URL: https://mcp.srgplus.com/mcp
3. Leave OAuth fields empty — the wizard will discover, DCR-register, and redirect to a consent page
4. On the consent page: paste your SRG+ workspace API key
5. Tools appear in claude.ai

Endpoints exposed (all under the same hostname as /mcp):

Endpoint	Purpose
/.well-known/oauth-authorization-server	RFC 8414 metadata
/.well-known/oauth-protected-resource	RFC 9728 metadata
/oauth/register	RFC 7591 Dynamic Client Registration
/oauth/authorize	Authorization endpoint with consent page
/oauth/token	Token endpoint (PKCE S256 required)
/oauth/revoke	RFC 7009 revocation

Backwards compatibility: the X-API-Key header and Authorization: Bearer srgplus_... flows from above still work. OAuth tokens (RFC-shaped JWTs) are detected automatically when the bearer value doesn't start with srgplus_.

Multiple workspaces

Each SRG+ workspace API key is scoped to a single workspace, so one OAuth session today connects one workspace.

To connect Claude to several workspaces at once, add the SRG+ connector multiple times in claude.ai → Settings → Connectors. Each instance goes through its own OAuth flow with the API key for that workspace:

SRG+ (Acme)       → https://mcp.srgplus.com/mcp  → API key for Acme workspace
SRG+ (Personal)   → https://mcp.srgplus.com/mcp  → API key for Personal workspace
SRG+ (Studios)    → https://mcp.srgplus.com/mcp  → API key for Studios workspace

Tools from each connector show up in claude.ai under their connector name, so you can scope a request to a specific workspace by mentioning the connector ("use SRG+ Acme to find content X").

A single-OAuth multi-workspace flow (Airtable-style: pick multiple workspaces in one consent screen, server provisions scoped keys automatically) is tracked in SRGDEV-27 and will land in a future release. Until then, the multi-connector approach above covers the same use case with no extra code.

Production secrets

In production, set these via GCP Secret Manager so token state survives process restarts:

Env var	Purpose
OAUTH_ISSUER	Canonical issuer URL (e.g. https://mcp.srgplus.com)
OAUTH_CLIENT_REGISTRATION_KEY	HMAC key for DCR client_id JWTs
OAUTH_TOKEN_SIGNING_KEY	HMAC key for codes/access/refresh tokens
OAUTH_API_KEY_ENCRYPTION_KEY	32-byte AES-GCM key (base64url) for wrapping the SRG+ workspace api_key inside JWTs

If any are unset the server generates an ephemeral random key per process — fine for local development, but every process restart invalidates all in-flight authorizations.

How auth works

Each request must carry the workspace API key in either header:

• X-API-Key: srgplus_...
• Authorization: Bearer srgplus_...

The server doesn't pre-validate the key — it binds it to the SDK's per-request contextvar via SRGClient.use_api_key(...) and lets the SRG+ SDK make the actual call. Bad keys surface as 401 from the upstream API on the first tool invocation.

A single shared SRGClient (and therefore a single httpx connection pool) serves every request, so the per-request overhead is just a contextvar set/reset — no per-key client construction or cache.

Local stdio (developer mode)

Use this when you're building locally against SRG+ and want a child-process MCP without running an HTTP server.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "srgplus": {
      "command": "uvx",
      "args": ["srgplus-mcp"],
      "env": {
        "SRG_API_KEY": "srgplus_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. The uvx command downloads and runs the package automatically — no separate install step needed.

Claude Code

claude mcp add srgplus -- uvx srgplus-mcp
export SRG_API_KEY=srgplus_your_key_here

Getting an API key

Log in to SRG+ → Settings → Workspaces → Select Workspace → API Keys → create a new key. Use the same key for both stdio (SRG_API_KEY env var) and hosted HTTP (X-API-Key header).
