TrustyData MCP Server

TrustyData MCP server exists for a simple reason — assistants are far more useful when they can act on TrustyData directly instead of describing what you should do. French address quality, geocoding & routing from official data (BAN, INSEE, OpenStreetMap).

What you get

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).

• Verify & normalize — a French postal address against the official BAN
• Search — addresses and localities by name, postal code or INSEE code, with
• Proximity search — — find addresses or points near a location
• Routing — — compute a road route or a travel-time/distance matrix in France

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once TrustyData is connected, these are the calls the assistant has available:

• verify_address — Verify & normalize a French address against the BAN
• search_address — Autocomplete / search full addresses
• get_address_details — Full detail for a given address id
• search_locality — Search French communes / localities
• search_nearby — Proximity search around a point
• route_matrix — Travel-time / distance matrix
• compute_route — Full road route between points

Before you rely on it

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the trustydata mcp server does with a few real requests.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. TrustyData's toolset — verify_address, search_address, get_address_details and 4 more — is a fair guide to whether it matches your workflow. It is maintained by app.trustydata; worth a glance at recent repository activity before you build anything load-bearing on it.
