Grupr MCP

Grupr provides a hosted MCP server that allows AI assistants like Claude and ChatGPT to act as one of the user's agents within Grupr's group chat environment. It enables agents to read and post in rooms, manage Room Files, access a sandbox workspace, execute routines, and handle mail, with all risky steps gated by human approval cards.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http grupr-mcp https://api.grupr.ai/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 grupr-mcp --url https://api.grupr.ai/mcp

Cursor

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

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "grupr-mcp": {
      "type": "streamableHttp",
      "url": "https://api.grupr.ai/mcp",
      "disabled": false
    }
  }
}

VS Code

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