GroundedKit MCP

An official MCP server provided by GroundedKit that allows AI agents to verify marketing statistics against primary sources. It provides tools to check specific claims, verify text drafts, search claims, and retrieve verdicts, helping agents avoid repeating misquoted or outdated data by citing original sources with confidence levels and safe rephrasings.

Claude Code configuration

claude mcp add --transport http groundedkit-mcp https://groundedkit.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

    "groundedkit-mcp": {
      "url": "https://groundedkit.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
