Who it is for
Anyone checking a French company's registration, officers or establishments.
Official French company records from the RNE by name or SIREN
Overview
France's Registre National des Entreprises is the official record of registered companies, and this connector queries it directly. A company can be found by name or SIREN, returning its full record: legal name, legal form, share capital, registered office, APE/NAF activity code, directors, and whether it is active or struck off.
Two lookups run sideways from there. Establishments and their SIRET numbers can be listed, and every company a given person directs can be retrieved. A fifth checks whether a company name is already taken before registration. No account is required. Contract-Factory publishes it at community tier.
Anyone checking a French company's registration, officers or establishments.
Five tools answered without credentials, matching the listing: search_company and get_company for lookup, get_etablissements for branch SIRETs, get_dirigeant_companies for a director's other companies, and check_name_availability for pre-registration checks.
Availability
Contract-Factory — Sociétés & SIREN is listed in the Claude connectors directory only. Contract-Factory has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
Contract-Factory — Sociétés & SIREN publishes 5 tools to Claude, a deliberately narrow surface; only 22.3% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Finance publishes 12, so this one sits 7 tools below its bucket's median, 133rd of 159.
It falls in the 4-6 tools band, which holds 16.2% of the Claude directory.
A direct call to the endpoint returned 5 tools, matching the 5 the listing publishes. Probed 2026-08-07.
search_companyget_companyget_etablissementscheck_name_availabilityget_dirigeant_companiesContract-Factory — Sociétés & SIREN publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
https://www.contract-factory.com/mcp.php Contract-Factory — Sociétés & SIREN is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.

This is an independent catalogue entry compiled by Node8 from Contract-Factory — Sociétés & SIREN's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Contract-Factory, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
