sirenic

Connect Sirenic to your assistant

Our 77 tools covering French and European company data plug into an assistant by pasting a single URL. Your assistant then queries the official registers itself, without you leaving the conversation.

The URL to paste

https://api.sirenic.eu/mcp/connecteur

Remote MCP server, streamable HTTP transport. The same address for every client below.

Two ways to authenticate

1. OAuth

  • The client opens a Sirenic window: you sign in, you authorise, and that is it.
  • Nothing to type in: no client ID, no secret. Registration happens on its own.
  • The token issued expires after one hour and renews itself until you revoke it.

2. API key

  • For clients offering an API key instead of OAuth.
  • Your srn_live_… key goes in X-Api-Key or Authorization: Bearer.
  • Create the key in your account, and revoke it in the same place.

Claude Code

claude mcp add --transport http sirenic \

Without a header, the OAuth flow opens in your browser.

What it costs

A verified account gets 100 free calls per month on routes priced at $0.01 or less. Beyond that, each call is charged to your credits at the price shown on the route, exactly like a direct API call: plugging in an assistant changes no price.
