odoo-model-mcp 0.1.0a1

MCP server exposing Odoo model registry without a database connection

odoo-model-mcp

MCP server that exposes Odoo's model registry (fields, inheritance, methods) without needing a database connection.

Point it at any Odoo project directory and get instant, structured answers about models, fields, method override chains, and inheritance graphs — powered by Odoo's own MetaModel registry loaded in-memory.

Status: Pre-alpha (0.1.0a1). Works with Odoo 16–18. Odoo 19 support is in progress.

How it works

1. MCP server (this package) receives tool calls via stdio.
2. It auto-detects the Odoo project structure (odoo-bin, addons paths, venv).
3. A persistent worker subprocess is spawned in the project's own Python venv, loading the full model registry once (~4 seconds).
4. Subsequent queries are served over a Unix domain socket in 1–15 ms.
5. Workers auto-shutdown after 10 minutes of inactivity.

Each project gets its own isolated worker process, so you can work with multiple Odoo versions simultaneously without conflicts.

Installation

# With uv (recommended)
uv tool install odoo-model-mcp

# With pip
pip install odoo-model-mcp

Usage with Claude Code

Add to your ~/.claude.json (global) or project .claude/settings.local.json:

{
  "mcpServers": {
    "odoo-model-registry": {
      "type": "stdio",
      "command": "odoo-model-mcp",
      "args": []
    }
  }
}

If installed with uv and not on PATH:

{
  "mcpServers": {
    "odoo-model-registry": {
      "type": "stdio",
      "command": "uv",
      "args": ["run", "--project", "/path/to/odoo-model-mcp", "odoo-model-mcp"]
    }
  }
}

Tools

All tools accept a project_path pointing to the root of an Odoo project. Addons paths and the Odoo source location are auto-detected from the project structure (or can be overridden with addons_paths). Modules can be excluded by name with exclude_modules (useful when a module has unresolvable Python dependencies).

detect_project_info

Detect an Odoo project's structure without loading the registry. Returns odoo_path, addons_paths, python_bin, and odoo_version.

search_models

Search models by name or description substring.

search_models(project_path="/path/to/project", query="sale.order")

model_info

Full metadata for a model: all fields (with types, compute methods, related fields, module overrides), inheritance chain, extending modules (from MRO), and decorated methods.

model_info(project_path="/path/to/project", model_name="sale.order")

field_info

Detailed info for a single field: type, compute method, depends, store, index, related, groups, and which modules defined or overrode it.

field_info(project_path="/path/to/project", model_name="sale.order", field_name="amount_total")

method_overrides

Override chain for a method across the MRO, with source file locations (file path and line number) for each override.

method_overrides(project_path="/path/to/project", model_name="sale.order", method_name="_compute_amounts")

model_graph

Inheritance graph around a model: which modules extend it (same _name), mixin parents (different _name), delegation parents (_inherits), and child models that inherit from it.

model_graph(project_path="/path/to/project", model_name="sale.order")

Project auto-detection

The server detects project structure automatically:

• Odoo source: looks for odoo-bin or the odoo/ Python package
• Addons paths: parses odoo.conf / .odoorc, or scans for directories containing modules (subdirs with __manifest__.py)
• Python venv: checks .venv/, venv/, env/
• Odoo version: reads from .env (ODOO_VERSION=) or odoo/release.py

Worker process (project's own venv)
    - Loads Odoo registry via MetaModel._build_model()
    - Resolves full inheritance (MRO, __bases__, _build_model_attributes)
    - Serves queries from in-memory registry
