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:

ATTIO_ACCESS_TOKEN

Step 1 — Get credentials

attio.com).

Setup:

  1. Sign in to Attio → top-right avatar → API & access → Create an access token (or set up an OAuth app).
  2. Pick scopes: at minimum object_configuration:read, record_permission:read, record_permission:read-write, list_configuration:read, note:read-write.
  3. Copy the token. Set ATTIO_ACCESS_TOKEN.

Authentication: Authorization: Bearer ${ATTIO_ACCESS_TOKEN}.

Object model: Attio is highly schema-flexible. Default objects are people, companies, deals, users, workspaces. You can add custom objects (object_slug). Each object has attributes (fields) — different per workspace.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

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/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
  2. Save the file and restart gemini.
  3. Run /mcp inside the Gemini CLI — Attio should be listed as available.
  4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.
