Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

MICROSOFT_GRAPH_ACCESS_TOKEN

Step 1 — Get credentials

0 — Bookings endpoints (learn.microsoft.com/en-us/graph/api/resources/booking-api-overview).

Setup:

  1. Register an Azure AD app at https://portal.azure.comApp registrations → New registration.
  2. API permissions → Microsoft Graph → Delegated (or Application) → add: Bookings.Read.All, BookingsAppointment.ReadWrite.All (write needs admin consent).
  3. Run OAuth2 authorization-code (or client-credentials) flow against login.microsoftonline.com/{tenant}/oauth2/v2.0/token to get an access token.
  4. Set MICROSOFT_GRAPH_ACCESS_TOKEN.

Authentication: Authorization: Bearer ${MICROSOFT_GRAPH_ACCESS_TOKEN}.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Step 3 — Add the connector in Gemini

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → Profile → MCP API Keys → New Key.
  2. Save the file and restart gemini.
  3. Run /mcp inside the Gemini CLI — Microsoft Bookings should be listed as available.
  4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp to the tools array of your request with the same Bearer header.
