Overview

AI-generated overview

A remote MCP server that gives an assistant public French land and property facts for an address, commune, building permit or cadastral parcel, with no API key.

What you can do
Look up an address's legal-entity owners, cadastral parcel, size, zoning and allowed uses, and planning prescriptions, plus sales and energy labels per the description line about public facts for an address, parcel, zoning, risks, permits, sales and energy labels, and the tool's own list of owners, parcel, zoning and prescriptions (the description also mentions risks, sales and energy labels). The address tool's own list covers legal-entity owners, parcel and size, zoning and allowed uses, and prescriptions; the description line adds risks, sales and energy labels, which the tool list does not confirm. The commune tool's own list covers addressed streets, median price per square metre, rent,
When to use it
Use it when you need public French cadastral, zoning, planning or property-market facts for a specific address, commune, parcel or permit, without signing up for a data provider.
Requirements
Remote endpoint at aucadastre.fr over streamable HTTP; no authentication, environment variables or headers declared. Network access to the service is needed.
Before you install
Results are public French land and planning data, so treat them as informational rather than authoritative. The parcel tool does not return individual owners; only legal entities appear, with SIREN and situation date. Verify figures such as prices, taxes and permit status against official sources before relying on them.

Installation

In SourceWeft

  1. Open Aucadastre in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/fr.aucadastre%2Faucadastre/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Une parcelle cadastrale francaise par sa reference

Une parcelle par son identifiant a quatorze caracteres (code INSEE, prefixe, section, numero, par exemple 940810000E0107) : sa contenance, sa commune, et la voie la plus proche de son centre, dont le jumeau porte tout le reste. Le proprietaire n'y est pas : ceux qui sont des personnes morales se lisent dans le jumeau de la voie, un particulier nulle part.
