Certica in Claude and ChatGPT

The MCP connector lets you verify a carrier straight from a conversation with your AI assistant. The assistant runs the same verification as the Certica app and gets the result: the verdict, every check and the registry data.

Server URL

https://api.certica.eu/mcp

The connector is a remote MCP server with OAuth sign-in. You sign in with the same account you use on certica.eu. No API key is needed.

Connect in Claude

  1. Open Settings, then Connectors.
  2. Choose Add custom connector and paste the server URL.
  3. Click Connect and sign in to Certica.
  4. In a conversation, turn on the Certica connector in the tools menu.

On Team and Enterprise plans, an organization owner adds the connector in the organization settings. Each member then connects their own Certica account.

Connect in ChatGPT

  1. Open Settings, then Apps and Connectors.
  2. Until Certica is listed in the app directory, turn on developer mode in the advanced settings.
  3. Create a connector, paste the server URL and choose OAuth sign-in.
  4. Sign in to Certica and pick the connector in a conversation.

Tools

verify_carrier
Verifies a carrier: company registry, EU VAT (VIES), transport licence, vehicle liability insurance where available, the email domain and Certica's freight fraud database. Returns the verdict (ok, info, warning, blocked), every check including passed ones, and the data from each source.
get_verification
Gets a verification result by its ID, for example when a verification took longer than a minute.
list_verifications
Lists up to 25 recent verifications in your organization.

Example prompts

  • Check this Polish carrier: the NIP, email and truck plate are in the order above.
  • Verify this Czech company by its IČO and tell me if I can give it a load.
  • Show my recent verifications and list the ones with warnings.
  • Using the KRS data, describe this company's board, shareholders and finances.

Credits and account

One full verification uses one credit from your Certica account, the same as in the app. A new account gets 20 free verifications. Results from the connector appear in your organization's verification history, where you can open the full report.

Data and privacy

  • The assistant sends Certica only the tool arguments: country, company number, carrier email, registration plates and haulage type. Certica does not receive your conversation.
  • The verification result goes back to the assistant. From there Anthropic (Claude) or OpenAI (ChatGPT) processes it under its own terms and privacy policy.
  • The connector only sees verifications of the organization you sign in to. It does not return personal ID numbers, files or internal technical data.
  • You revoke access by disconnecting the connector in Claude or ChatGPT.

Details are in the privacy policy.
