What is Certifier MCP?

MCP (Model Context Protocol) is an open standard that lets AI assistants connect to external tools securely.

Certifier MCP server uses this standard to give your AI assistant direct access to your Certifier workspace. Once connected, your assistant can:

  • search, list, and inspect existing credentials

  • create, issue and send credentials

  • create and manage credential templates (groups)

  • list and inspect available design templates

Connect any MCP-compatible AI assistant to Certifier using this server URL:

https://api.certifier.io/v1/mcp

🔎 For detailed setup instructions for Claude Code, Codex and OpenCode, see the Certifier MCP Developer Docs.

💡 If you're a workspace admin and want to give your whole team access, check the Guide for Organizational Accounts.
