TrustyData

License: MIT MCP Status

Connect your LLM (Claude, ChatGPT, IDE assistants…) to TrustyData — French address data quality, geocoding and routing, built on official open data sources (BAN, INSEE, OpenStreetMap).

▶️ Try it live — public demo agent, no account needed Ask a real agent to verify an address, list communes or compute a route: it calls this MCP server in front of you.

TrustyData MCP demo agent

This is a hosted, remote MCP server — there is nothing to install or run. Point your MCP client at the endpoint below and sign in with your TrustyData account.

Endpoint	https://mcp.trustydata.app/mcp
Transport	Streamable HTTP
Auth	OAuth 2.1 (sign in with your TrustyData account)
Docs	https://trustydata.fr/docs/
Status	https://status.trustydata.app

This repository hosts the public listing metadata for the TrustyData MCP server (server.json, documentation, examples). The server itself is a hosted service — the source of the underlying data API is not part of this repo.

What it does

TrustyData turns messy French addresses into clean, authoritative data and adds geographic context, directly inside your LLM conversation:

• Verify & normalize a French postal address against the official BAN reference (the result is authoritative — an empty result means no match).
• Search addresses and localities by name, postal code or INSEE code, with optional filters (department, region, population).
• Proximity search — find addresses or points near a location.
• Routing — compute a road route or a travel-time/distance matrix in France (OpenStreetMap).

Richer fields (e.g. INSEE Filosofi statistical grid, Lambert 93 coordinates) are returned depending on your plan.

Tools

Tool	What it does	Minimum plan
verify_address	Verify & normalize a French address against the BAN	Discovery
search_address	Autocomplete / search full addresses	Discovery
get_address_details	Full detail for a given address id	Discovery
search_locality	Search French communes / localities	Discovery
search_nearby	Proximity search around a point	Growth
route_matrix	Travel-time / distance matrix	Growth
compute_route	Full road route between points	Business

All tools are advertised to every client. If your plan doesn't cover a tool, it returns an actionable upgrade message instead of failing silently.
