mcp-server-dolibarr

An MCP server for Dolibarr ERP/CRM. Lets Claude (or any MCP-compatible client) read and manage your Dolibarr thirdparties (clients/suppliers), commercial proposals, contracts, and invoices directly — no manual API scripting needed.

Built by Nexora 360 Digital, released for anyone running Dolibarr to use for free.

Requirements

• A running Dolibarr instance (v15+) with the REST API module enabled (Setup → Modules → API)

• A Dolibarr API key for the user the assistant should act as (your user profile → API/REST tab → Generate Key)

• Node.js 18 or newer

Installation

No install needed — run it directly with npx (see configuration below), or clone this repo and run npm install.

Configuration

The server reads two environment variables:

Claude Code

claude mcp add dolibarr \
  --env DOLIBARR_URL=https://your-domain.com/dolibarr/api/index.php \
  --env DOLIBARR_API_KEY=your_api_key_here \
  -- npx -y mcp-server-dolibarr

Claude Desktop / other MCP clients

Add to your MCP config file (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "dolibarr": {
      "command": "npx",
      "args": ["-y", "mcp-server-dolibarr"],
      "env": {
        "DOLIBARR_URL": "https://your-domain.com/dolibarr/api/index.php",
        "DOLIBARR_API_KEY": "your_api_key_here"
      }
    }
  }
}

Notes & known Dolibarr quirks

• Proposals, contracts and invoices are created in two steps in Dolibarr's API: create the header first, then add line items separately (*_lines endpoints). The tools above mirror that.

• Dolibarr 23.x line-creation silent-failure bug: on Dolibarr 23 instances, POST /{proposals|invoices|contracts}/{id}/lines actually expects the body wrapped as {"request_data": {...fields...}}, not a flat object of fields (despite this not matching the field names documented for older Dolibarr versions). Sending a flat object doesn't error — it silently creates a blank line with special_code: "3" (no description, qty 0, price 0) instead of your real data. dolibarr_add_proposal_line, dolibarr_add_invoice_line and dolibarr_add_contract_line already wrap the body correctly to work around this. If you see blank/special_code: 3 lines appearing on Dolibarr versions other than 23.x, check your instance's live schema at /api/index.php/explorer/swagger.json and adjust index.js accordingly — Dolibarr's REST API shape has changed across major versions.

• On some Dolibarr versions, certain endpoints (e.g. contracts) only work reliably for admin/SuperAdmin API keys — if a non-admin key fails, try generating the key as an admin user.

• country_id for thirdparties follows Dolibarr's internal country table (e.g. 144 = Sri Lanka in standard Dolibarr installs) — check your instance if unsure.

Contributing

Issues and PRs welcome — this was built to scratch a real itch (managing client proposals/invoices via Claude) and intentionally keeps a dolibarr_request escape hatch so it stays useful even where dedicated tools haven't been written yet.
