mcp-gee-sweet

Pre-release

This release is a pre-release and may not be stable for production use.

mcp-gee-sweet

The Google Workspace MCP server built for depth.

GitHub License

Google ships its own Sheets and Docs MCP servers now (Developer Preview), but they're shallow — thin CRUD, both approval-gated. mcp-gee-sweet goes deeper: raw formula access — reads =VLOOKUP() and friends directly, structural Docs support (colspan/rowspan tables, themes, named styles, an HTML/Markdown→AST→Docs pipeline), plus complete Drive and Calendar coverage Google's preview doesn't touch at all.

A few things no other Workspace MCP has:

Caching — repeated reads return in ~2ms from a local cache instead of a round-trip API call every time.
Formula access — reads raw =VLOOKUP(), =SUM(), and =IF() expressions, not just the values they produce.
Local sync — two-way sync between a local folder and Google Drive.

Install (stable):

uvx mcp-gee-sweet

Install (bleeding edge — every code change on develop):

uvx --prerelease=allow mcp-gee-sweet

Google Calendar	17	—	Event CRUD, free-slot finder across multiple calendars

Quick start

Option A: `uv` — local use and development

If you cloned the repo or just want to use the server from your machine, uv is all you need. No Docker required.

git clone https://github.com/khuisman/mcp-gee-sweet.git
cd mcp-gee-sweet
uv sync

Then point your MCP client at it using stdio transport (see MCP client config below). The client spawns the server as a subprocess on demand — each session gets its own isolated process, so restarting the server for a code change or config update doesn't affect other open sessions.

Option B: Docker — persistent shared server (SSE)

Use Docker when you want a single long-running server that multiple clients connect to over SSE — for example, Claude Desktop talking to the same instance as Claude Code.

git clone https://github.com/khuisman/mcp-gee-sweet.git
cd mcp-gee-sweet
make build   # build the container image
make start   # start the server (SSE on port 47000)
make logs    # tail logs

Point your MCP client at http://localhost:47000/sse.

Note: when using SSE, all clients share one server process. After a code change or restart (make restart), you must also restart each MCP client to reconnect.

Configuration

The server tries auth methods in a waterfall by default, OAuth first — it authenticates as you and has full personal Drive access, which is what local/dev use (Option A above) needs. For OAuth, download an OAuth Client ID JSON from GCP Console and point the server at it:

export CREDENTIALS_PATH="/path/to/credentials.json"

Service accounts (recommended for headless server deployments — see Option B above), base64 credential injection, and Application Default Credentials are also supported. See Authentication for all options.

MCP client config

Claude Desktop — stdio (cloned repo):

{
  "mcpServers": {
    "mcp-gee-sweet": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/mcp-gee-sweet", "mcp-gee-sweet"],
      "env": {
        "CREDENTIALS_PATH": "/path/to/credentials.json"
      }
    }
  }
}

Claude Desktop — SSE (Docker):

{
  "mcpServers": {
    "mcp-gee-sweet": {
      "transport": "sse",
      "url": "http://localhost:47000/sse"
    }
  }
}

See Client Setup for more options including tool filtering.
