OpenLMNP MCP MCP server

An open-source accounting MCP server for French furnished rentals (LMNP) that allows AI agents to manage income, expenses, depreciation, and tax returns in natural language. It supports reading financial data, creating records, calculating fiscal results, and producing tax documents like the liasse fiscale 2031.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http openlmnp-mcp https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add openlmnp-mcp --url https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48

Cursor

Merge this server into .cursor/mcp.json in your project, then enable openlmnp-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "openlmnp-mcp": {
      "url": "https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "openlmnp-mcp": {
      "type": "streamableHttp",
      "url": "https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start openlmnp-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "openlmnp-mcp": {
      "type": "http",
      "url": "https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http openlmnp-mcp https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "openlmnp-mcp": {
      "url": "https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "openlmnp-mcp": {
      "serverUrl": "https://app.openlmnp.fr/mcp?demo_token=openlmnp_demo_ro_ebd891f45e8a771ca1a718f239b733b438a31d48"
    }
  }
