Requisitos previos

Las instrucciones de configuración completas están incluidas en el conector (visibles en el store al seleccionarlo). Las variables de entorno requeridas:

MICROSOFT_GRAPH_ACCESS_TOKEN

Paso 1 — Obtener credenciales

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

Setup:

  1. Register an Azure AD app at https://portal.azure.comApp registrations.
  2. API permissions → Microsoft Graph → Delegated (or Application) → add: Team.ReadBasic.All, Channel.ReadBasic.All, ChannelMessage.Send, ChannelMessage.Read.All (write needs admin consent).
  3. Run OAuth2 to get an access token. Set MICROSOFT_GRAPH_ACCESS_TOKEN (shared with Microsoft Bookings adapter).

Authentication: Authorization: Bearer ${MICROSOFT_GRAPH_ACCESS_TOKEN}.

Teams hierarchy: Team → Channel → Message (+ replies). Each Team is also a Microsoft 365 Group.

…(continued in the in-app connector instructions)

Paso 2 — Instalar el adapter

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

Paso 3 — Añadir el conector en Gemini

Gemini CLI lee servidores MCP desde ~/.gemini/settings.json (o %APPDATA%\gemini\settings.json en Windows). Añade:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
    }
  }
}
  1. Obtén tu MCP API key desde AnythingMCP → Perfil → MCP API Keys → Nueva Key.
  2. Guarda el archivo y reinicia gemini.
  3. Ejecuta /mcp en la Gemini CLI — Microsoft Teams debería aparecer como disponible.
  4. Vertex AI Studio: pasa https://cloud.anythingmcp.com/mcp al array tools de tu petición con el mismo header Bearer.
