Odoo

Odoo MCP server

An MCP server that lets an AI assistant (Claude Desktop, Claude Code, or any MCP client) read your Odoo sales, purchasing, manufacturing and stock data, and, only if you turn it on, update a purchase order line's promise date.

• 12 read tools and 1 write tool (listed below).
• Read-only by default. The write tool needs ODOO_MCP_ENABLE_WRITES=true on the server and an exact confirmation text on every call.
• Talks to Odoo's external JSON-RPC API (/jsonrpc) as the user you configure. Odoo's access rights apply.
• Runs locally over stdio. No telemetry; it connects only to your Odoo.

Built by Helios One. MIT license.

Quickstart (2 minutes)

You need Node.js 20 or newer and an Odoo user that can log in to the external API.

1. Get an API key in Odoo (recommended over a password): click your avatar, then My Profile / Preferences, open Account Security, click New API Key. Copy the key.

2. Add the server to your MCP client.

Claude Code:

claude mcp add odoo \  -e ODOO_URL=https://odoo.example.com \  -e ODOO_DB=mydb \  -e [email protected] \  -e ODOO_API_KEY=your-api-key \  -- npx -y @heliosone/odoo-mcp

Claude Desktop: open Settings > Developer > Edit Config and add this to claude_desktop_config.json, then restart Claude Desktop:

{  "mcpServers": {    "odoo": {      "command": "npx",      "args": ["-y", "@heliosone/odoo-mcp"],      "env": {        "ODOO_URL": "https://odoo.example.com",        "ODOO_DB": "mydb",        "ODOO_USERNAME": "[email protected]",        "ODOO_API_KEY": "your-api-key"      }    }  }}

3. Ask, for example: "Which purchase order lines are late, and by how many days?" or "What is the status of S00042?"

Settings

The server starts even when settings are missing, so your client can list the tools. Each call then returns CONFIGURATION_ERROR with the names of the missing settings.

Tools

List tools take limit (default 50, max 500) and offset. Results are Odoo's own field values, plus a few computed fields (qty_open, days_late, promised_date). Fields that do not exist in your Odoo version are left out.

The write tool

update_po_line_promise_date changes date_planned on one purchase order line (for example after a vendor confirms a new date). It runs only when both are true:

1. the server was started with ODOO_MCP_ENABLE_WRITES=true, and
2. the call includes "confirmation": "CONFIRM update_po_line_promise_date".

Otherwise it returns WRITES_DISABLED or CONFIRMATION_REQUIRED and does not call Odoo. A date without a time is stored as 12:00 UTC so it shows as the same day in most time zones. The result shows the value before and after.

What has been tested

Tested on 24 October 2026, with the packed npm tarball installed into an empty project and its odoo-mcp command driven over stdio by the official MCP TypeScript SDK client, against fresh self-hosted Odoo Community 17.0, 18.0 and 19.0 (built from the official odoo/odoo branches; Sales, Purchase, Inventory and Manufacturing installed; fictional records). In each version:

• all 13 tools were listed and all 12 read tools returned the seeded records (21 tool calls and 25 checks per version, all passed);
• the write tool was refused with writes off (WRITES_DISABLED), refused without the confirmation text (CONFIRMATION_REQUIRED), then succeeded, and a direct Odoo read confirmed the new date;
• the server logged in with an Odoo API key; one session used the plain password instead, and a wrong password returned AUTH_FAILED;
• one call also went through the MCP Inspector CLI.

Logs: proof/. Unit tests (npm test, against an in-memory fake Odoo) pass on Node.js 20 and 25.

Not tested: Odoo Online (odoo.com hosting) and Odoo.sh, Odoo Enterprise, Odoo versions before 17, multi-company setups, and large databases. Odoo Online offers the external API only on some plans. Odoo 19 deprecated /jsonrpc (removal planned for Odoo 22, fall 2028, and Odoo Online 21.1, winter 2027) in favour of its JSON-2 API; this server does not use JSON-2 yet. Odoo 19 logs a deprecation warning for each /jsonrpc call.

Development

npm cinpm test

proof/run-live.sh 18.0 repeats the live test in a disposable Linux machine (it installs PostgreSQL and Odoo; do not run it on your workstation).

Security

See SECURITY.md. Use a dedicated Odoo user with only the rights the assistant needs.
