Sentinelle syndic: French condominium manager and mandate end date MCP server

MCP server and pay-per-call API for AI agents. From the official French condominium registry (ANAH, about 656,000 condominiums), it returns who manages a condominium and when the manager's mandate ends, and lists the condominiums of a town, postcode, department or manager portfolio whose mandate ends soon.

Why it exists

Every French condominium (copropriété) is registered with the national registry run by the Agence nationale de l'habitat (art. L711-1 Code de la construction et de l'habitation). Its manager, the syndic, declares its mandate there. A mandate lasts three years at most (art. 28 of decree 67-223 of 17 March 1967); before it ends, the co-owners' general meeting renews it or picks another manager.

Property managers who want to bid before that meeting, building insurers, contractors and real-estate software vendors need to know which mandates end when. The registry is public but only as a large daily file. This server indexes it and answers in one call.

Connect

Any MCP client can connect and call syndic_example. Calling a paid tool returns an x402 payment required answer: the client must support x402 payments to pay it (see below).

Paying with x402

The paid tools follow the x402 MCP convention: the first call returns the payment requirements (scheme exact, network Base eip155:8453, asset USDC, amount 10000 = 0.01 USDC or 30000 = 0.03 USDC); the client signs a payment, puts it in the request _meta under x402/payment, and calls again. The payment is settled only if the tool succeeds: invalid input is never charged.

A minimal Python client with the official x402 SDK is in examples/pay_mcp.py. The same service is also sold over plain HTTP (GET /v1/syndic and GET /v1/syndic/echeances, HTTP 402 then retry), which every x402 HTTP client supports.

Data and limits

• Source: Registre national d'immatriculation des copropriétés, Agence nationale de l'habitat (ANAH), published on data.gouv.fr under the Licence Ouverte 2.0 (Etalab), refreshed daily.

• The data is declared by the managers themselves: a past end date may mean an outdated record rather than a condominium without a manager; statut says which case the record shows.

• Only professional managers (companies) are named. The identity of volunteer managers is not published by the registry and is never returned. No personal data is returned or stored.

• Information only, not legal advice.

Same author

• Sentinelle créances: French insolvency notices per company and the creditor claim filing deadline.

• Sentinelle catnat: French natural-disaster decrees per commune and the open insurance-claim deadline.
