Pappers MCP server: connect AI agents to French company data from the EU

Pappers is a Paris-based company that aggregates more than 100 official French sources into one database: Sirene from INSEE, the national business register (RNE) from INPI, BODACC legal notices, filed annual accounts, DVF property sales, Judilibre court decisions and parliamentary activity.

Its official MCP server at https://mcp.pappers.fr exposes 35 tools over Streamable HTTP, plus a strategy tool that guides the agent through financial and legal analyses. Company and real estate tools draw on the credit balance of your Pappers API key; Justice and Politique need individual licences.

A sales team can ask for industrial SMEs in Brittany with revenue above €5 million and get a list with SIREN, directors and headcount, ready to import into a CRM. A credit analyst can have the agent compare three years of a supplier's accounts and flag falling margins or new collective proceedings in the BODACC.

Compliance teams use it for know-your-customer checks: beneficial owners, group structure and screening of directors against PEP and sanctions lists. M&A teams can screen a sector for companies with a given growth rate and operating result.

Create a Pappers account with API access and copy your API key from your customer area. On inference.eu, add the Pappers connector to an agent and paste the key; it is stored encrypted in the EU and never shown again in full. The connector then uses the server URL https://mcp.pappers.fr with token authentication.

Pappers also supports OAuth sign-in for some clients. Keep an eye on credit consumption, because detailed profiles and large searches use more credits than a simple SIREN lookup.

The data comes from public registers, but it still includes personal data such as directors' names, dates of birth and beneficial owners. The agent's requests go to Pappers, a French company, as they would through the Pappers API or website.

On inference.eu, the model that reads the results runs in EU data centres, and your API key is stored encrypted in the EU. Use the data for purposes the registers allow, such as due diligence or B2B prospecting, and document that use in your processing register.

All Pappers tools read data; the main risks are cost and use of personal data. Large multi-criteria searches and enriched profiles consume credits quickly, and a loop in an agent can drain a balance.

On inference.eu you can require a person to approve expensive calls, such as searches returning many results or profiles with paid options, and let SIREN lookups run freely. When results feed outreach in other connectors, require approval before anything is sent, so a person checks the list first.
