## Common questions

### What is the fr-legal-kit MCP server?

fr-legal-kit is an MCP server listed in the public MCP registry as io.github.CartonPliant/fr-legal-kit. French legal helpers for agents: e-invoice, L441-10, SIRET/IBAN. $0.01 USDC x402. This page covers its hosted endpoint (https://fr-legal-kit.monnet-yanis1.workers.dev/mcp).

### Is the fr-legal-kit MCP server safe to use?

fr-legal-kit scores 0 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the fr-legal-kit MCP server expose?

fr-legal-kit exposes 68 tools: late_penalties, einvoice_who, check_siret, check_iban, due_date, and 63 more. Their descriptions and schemas cost roughly 3,836 tokens of context every time the server is loaded.

### Does the fr-legal-kit MCP server require authentication?

Its publisher declares no required credentials for fr-legal-kit. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the fr-legal-kit MCP server still maintained?

fr-legal-kit has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 7 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
