Eurc402 MCP server

Which MCP servers are Eurc402's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.eurc402/eu-complianceverified in the MCP registry

The registry name sits under eurc402.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: validate EU VAT numbers against the VIES registry; look up normalized company records from ten European registers.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "validate EU VAT numbers against the VIES registry", the likely first call is validate_eu_vat.
  • For "look up normalized company records from ten European registers", the likely first call is lookup_eu_company.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • can do · validate EU VAT numbers against the VIES registry
  • can do · look up normalized company records from ten European registers
  • not sure · retrieve officers and registered addresses for EU companies

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
