Summary
Connects Claude to simap.ch, Switzerland's public procurement platform, with full read access to tenders and classification systems. You get search and detail retrieval for public contracts, plus navigation tools for CPV codes (procurement vocabulary), BKP (construction), NPK (standardized positions), and OAG (object types). Filter by canton, institution, date range, or procurement type. No API key needed since simap's endpoints are public. Runs via npx with stdio transport. Built by Digilac for anyone tracking Swiss government contracts, whether you're a bidder monitoring opportunities, a researcher analyzing procurement patterns, or building compliance workflows that need structured access to official tender data.

Prerequisites
- An MCP-compatible client — Claude Desktop is the easiest if you are not a developer.
- Node.js ≥ 22 — only for clients that do not bundle it. Claude Desktop ships with its own Node.js, so there is nothing to install. For every other client, get it from nodejs.org (pick the LTS version).
- No simap account, no API key, no payment — the simap API is public and read-only.
Installation & Configuration
Claude Desktop (recommended)
-
In Claude Desktop, open Settings → Developer → Edit Config. This opens the folder holding
claude_desktop_config.json:- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%\Claude\claude_desktop_config.json
- macOS:
-
Open that file in a text editor and paste the block below. If the file already contains an
mcpServerssection, add only the"simap"entry inside it.{ "mcpServers": { "simap": { "command": "npx", "args": ["-y", "@digilac/simap-mcp"] } } } -
Save the file, then fully quit Claude Desktop (macOS: ⌘Q — closing the window is not enough) and reopen it.
-
Check it worked: the simap tools now show up under the tools icon in the message box. Ask "List the Swiss cantons in simap" — Claude should answer with the 26 cantons.
The very first launch downloads the server, which takes a few seconds. If the tools do not appear, check Settings → Developer for the server status and logs.
LM Studio
LM Studio follows the same mcp.json notation. Open the Program tab in the right-hand sidebar, then Install → Edit mcp.json, and add:
{
"mcpServers": {
"simap": {
"command": "npx",
"args": ["-y", "@digilac/simap-mcp"]
}
}
}
LM Studio does not bundle Node.js — install it from nodejs.org first. Tender search leans on the model's ability to chain tool calls, so results depend a lot on which local model you load.
Code editors & developer tools
Claude Code, Cursor, VS Code, Windsurf
They all take the same snippet — only the file and the top-level key change:
| Client | Where | Top-level key |
|---|---|---|
| Claude Code | claude mcp add simap -- npx -y @digilac/simap-mcp | mcpServers |
| Cursor | ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project) | mcpServers |
| VS Code (Copilot) | .vscode/mcp.json, or the MCP: Open User Configuration command | servers |
| Windsurf | ~/.codeium/windsurf/mcp_config.json | mcpServers |
{
"mcpServers": {
"simap": {
"command": "npx",
"args": ["-y", "@digilac/simap-mcp"]
}
}
}
- Claude Code — add
--scope userto enable it in every project, or--scope projectto write a.mcp.jsonshared with your team. Claude Code does not readmcpServersfromsettings.json. Verify withclaude mcp list. - VS Code uses
serversas the top-level key, notmcpServers. - Cursor loads MCP servers only at startup — quit and reopen it fully.
Alternative: global install
npm install -g @digilac/simap-mcp
Then point your client at the command directly:
{
"mcpServers": {
"simap": {
"command": "simap-mcp"
}
}
}
Alternative: from source
git clone https://github.com/Digilac/simap-mcp.git
cd simap-mcp
npm install
npm run build
Then point your client at the absolute path:
{
"mcpServers": {
"simap": {
"command": "node",
"args": ["/absolute/path/to/simap-mcp/dist/index.js"]
}
}
}
Usage
Once configured, just ask your AI assistant in natural language. Mention "in simap" to make sure the assistant routes the request through the MCP server:
- "Show me new tenders published today in simap"
- "Find construction tenders in canton Vaud in simap"
- "Give me the details of this tender in simap" (after a search)
- "Search CPV codes for IT services in simap"
