Groundtruth MCP

An official MCP server for Groundtruth, a company wiki and knowledge base built for AI. It allows agents to query pages, decisions, and records with cited sources, write back decisions and updates, and manage structured facts. The server supports tools like ask, search, get_page, and log_decision, enabling agents to act as teammates with proper attribution and freshness checks.

Endpoint and access

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http groundtruth-mcp-groundtruthhq https://groundtruthhq.tech/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add groundtruth-mcp-groundtruthhq --url https://groundtruthhq.tech/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable groundtruth-mcp-groundtruthhq in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "groundtruth-mcp-groundtruthhq": {
      "url": "https://groundtruthhq.tech/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "groundtruth-mcp-groundtruthhq": {
      "type": "streamableHttp",
      "url": "https://groundtruthhq.tech/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start groundtruth-mcp-groundtruthhq and inspect its tools.
VS Code configuration
{
  "servers": {
    "groundtruth-mcp-groundtruthhq": {
      "type": "http",
      "url": "https://groundtruthhq.tech/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http groundtruth-mcp-groundtruthhq https://groundtruthhq.tech/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "groundtruth-mcp-groundtruthhq": {
      "url": "https://groundtruthhq.tech/api/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "groundtruth-mcp-groundtruthhq": {
      "serverUrl": "https://groundtruthhq.tech/api/mcp"
    }
  }
