What the Contract-Factory — Sociétés & SIREN connector does

The Contract-Factory MCP server — branded infosociétés — connects official French company records to Claude, ChatGPT and any MCP-compatible agent. Its five read-only tools resolve a company name to a SIREN number, return a full registry profile, list establishments and SIRET numbers, map a person's directorships, and check whether a company name is already registered.

Contract-Factory — Sociétés & SIREN tools (5)

  • search_companyRead-only

    Recherche une ou plusieurs entreprises francaises par denomination sociale (nom) OU par numero SIREN. Si la requete est un SIREN (9 chiffres), renvoie directement l'entreprise correspondante. Sinon, effectue une recherche par nom et renvoie jusqu'a 10 resultats (denomination, forme juridique, activite, ville, SIREN, etat actif/radie). A UTILISER EN PREMIER lorsque l'utilisateur designe une entreprise par son NOM : cet outil renvoie le SIREN, que vous passez ensuite a get_company (fiche complete) ou get_etablissements. Utile pour trouver une societe, verifier une entreprise, retrouver un SIREN a partir d'un nom, ou lister les societes portant un nom donne. Source : infosociétés by Contract-Factory (données du Registre National des Entreprises - RNE). EN: Search French companies by trade/legal name or by SIREN number. Returns up to 10 matches with legal name, legal form, activity, city, SIREN and active/struck-off status. Call this FIRST when the user gives a company name, then pass the SIREN to get_company for full details. Use to find a company, look up a business, resolve a SIREN from a name, or list companies by name.

  • get_companyRead-only

    Fiche d'identite complete d'une entreprise francaise a partir de son numero SIREN (9 chiffres). Si vous ne connaissez que le NOM de l'entreprise (pas son SIREN), appelez D'ABORD search_company pour obtenir le SIREN, puis get_company avec ce SIREN — ne demandez pas le SIREN a l'utilisateur. Retourne la denomination sociale, le SIRET du siege, le numero de TVA intracommunautaire, la forme juridique (SAS, SASU, SARL, EURL, SCI, SA, SNC, entreprise individuelle...), le capital social, l'adresse du siege social, la date de creation, l'activite (code APE/NAF), l'etat (active ou radiee) et la liste des dirigeants actuels (gerant, president, directeur general) avec leur fonction. Source : infosociétés by Contract-Factory (données du Registre National des Entreprises - RNE). EN: Full company profile for a French business by its SIREN number (9 digits): legal name, head-office SIRET, VAT number (TVA intracommunautaire), legal form, share capital, registered office address, incorporation date, business activity (APE/NAF code), status (active/struck off) and current directors/officers. If you only have the company NAME (not the SIREN), FIRST call search_company to get the SIREN, then call get_company with it — do not ask the user for the SIREN. Use it to look up, verify or check a company, know who runs it, or read its official data.

  • get_etablissementsRead-only

    Liste tous les etablissements d'une entreprise francaise a partir de son numero SIREN (9 chiffres) : siege social, etablissement principal et etablissements secondaires. Pour chaque etablissement : numero SIRET (14 chiffres), role (siege, principal, secondaire), etat (ouvert ou ferme), enseigne, adresse complete et activites.

Renvoie les correspondances EXACTES et les noms PROCHES trouves dans le Registre National des Entreprises (RNE). Ideal avant de creer une SASU, SAS, SARL, EURL, SCI ou toute societe, pour choisir un nom disponible.

Limits

  • Name availability is not trademark clearance. Contract-Factory states this twice, in French and English, in the tool description and in the documentation: check_name_availability searches registered company names in the RNE and *"ce n'est pas une recherche d'antériorité de marque INPI"*. A name it reports as available may still infringe a registered trademark. This is a vendor disclaimer, reported as such, and this page offers no legal advice about the consequence.
  • The read-only guarantee is stated, not structurally enforced in the response. Every tool's output schema declares a source attribution block naming *infosociétés by Contract-Factory* and the RNE — but no output schema marks it required, and every one sets additionalProperties: true. So the attribution is declared in the contract but not enforced by it, unlike a server that makes a disclaimer a required field of every response envelope. What
  • This does not touch the vendor's formality business. Contract-Factory files incorporations and statute changes commercially, and none of that reaches MCP. Anything with legal effect requires going through its website, with a human adviser and a payment.
  • Rate limits are real and shared with the docs. 60 requests/minute and 2,000/day per IP. Because mcp.php sits on the marketing host, the same limiter fronts the documentation page — we drew a 429 with retry-after: 60 on the docs URL while probing the endpoint.
  • Results are capped. Ten search results per page (30 matches maximum), 20 establishments, 30 directors, 30 mandates per person, 15 near-name matches. A large group's full footprint will not come back in one call.
  • French companies only, and coverage stops at what the RNE holds. Annual accounts and filed deeds appear in the vendor's web directory but no tool returns them.
  • No OAuth boundary exists, because there is no authentication. All four RFC 9728 probes returned a 404 byte-identical to a nonsense control path, and no www-authenticate header appeared. There are no scopes to diff against the tool names — and with an entirely read-only surface, nothing for a scope to separate.
  • Anthropic's directory understates the surface. It records four prompts as zero. The names are harmless, but the listing is not a complete inventory of what the server serves.
  • Your queries are logged for 13 months, including the search term, which may be a person's name. Contract-Factory states it receives the AI platform's server IP rather than yours, and cannot link logs to an identified person.
  • Data currency is asserted, not measured. Contract-Factory states daily updates from INPI and INSEE. We did not verify update latency, and the vendor publishes no lag figure. We could not establish which open licence it redistributes the RNE under — neither the documentation, the privacy policy nor the site manifest names one, stating only that the data is restituted "in the same conditions" as the vendor's public web directory.
  • Struck-off companies are returned, flagged with actif: false. An agent that ignores the flag will report a dissolved company as though it were trading.

Frequently asked questions

Does the Contract-Factory connector write or generate contracts?

No. Despite the vendor's name, all five tools only read public company records. Contract-Factory's own technical documentation states the server exposes consultation tools only and that it creates, modifies and deletes no data. Every tool carries a readOnlyHint of true and a destructiveHint of false in the live handshake we ran on 2026-08-24.

Do you need an account to use the Contract-Factory SIREN connector?

No. We opened an anonymous connection to the endpoint on 2026-08-24 and the server completed the handshake and returned all five tools with no credential of any kind. Contract-Factory states the service needs no account, no sign-up and no authentication, and publishes no OAuth metadata at all.

Where does the French company data come from and how current is it?

From the Registre National des Entreprises held by the INPI, with the Sirene repository from INSEE named alongside it. Contract-Factory's machine-readable site manifest states the infosociétés data comes from INPI and INSEE and is updated daily. The connector serves the same records as the vendor's public infosociétés directory.

Can the connector tell you whether a company name is legally available?

Only partly, and the vendor says so itself. The check_name_availability tool searches company names already registered in the RNE. Contract-Factory's documentation states in both languages that this is not an INPI trademark availability search, so a name it reports as free may still infringe a registered trademark.

What are the rate limits on the Contract-Factory MCP server?

Sixty requests per minute and two thousand per day, applied per calling IP address. Contract-Factory publishes both figures in its technical documentation and enforces them live: our own probing drew an HTTP 429 carrying a retry-after header of 60 seconds. The docs page and the MCP endpoint share one host, so heavy reading can rate-limit both.

What personal data does the connector return about company directors?

Names, first names, roles and, for disambiguation, birth years. The get_dirigeant_companies tool lists every French company a named person directs or has directed, and its schema returns a date_naissance field. Contract-Factory masks individuals who opted out of INSEE diffusion, flagged as non_diffusible on a company record.

Does Contract-Factory log what your AI assistant asks it?

Yes, for up to 13 months. Article 3 ter of its privacy policy states it logs the query itself, which may contain a natural person's name, the AI platform's server IP rather than yours, hashed platform session identifiers, and technical metadata. It states it has no means of identifying the end user directly.

Which MCP prompts does the Contract-Factory server offer?

Four, though Anthropic's directory lists none of them. The live prompts/list call on 2026-08-24 returned analyser_societe for a full company analysis, verifier_nom for checking name availability, mandats_dirigeant for listing a person's corporate roles, and comparer_societes for a side-by-side comparison of two named French companies. All four are read-only.
