Attio MCP Server

Please install the `attio-mcp-server` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install the attio-mcp npm package** — The npm package is named attio-mcp (NOT attio-mcp-server). Install globally. Run: `npm install -g attio-mcp` (https://www.npmjs.com/package/attio-mcp)
- **Attio API key** — Generate an API key in Attio: app.attio.com/settings/api (https://app.attio.com/settings/api)

Canonical MCP server config (stdio transport):
- command: `attio-mcp`
- args: []
- required environment variables:
  - `ATTIO_API_KEY`: Attio API key (or use ATTIO_ACCESS_TOKEN for OAuth). If both are set, ATTIO_API_KEY wins. (example: `<your-attio-api-key>`)
- optional environment variables:
  - `ATTIO_ACCESS_TOKEN`: OAuth access token alternative to ATTIO_API_KEY (example: `<your-attio-access-token>`)
  - `ATTIO_WORKSPACE_ID`: Attio workspace ID (example: `<your-attio-workspace-id>`)
  - `ATTIO_DEFAULT_DEAL_STAGE`: Default stage for new deals (example: `Interested`)
  - `ATTIO_DEFAULT_DEAL_OWNER`: Default owner email for new deals (example: `<your-email>`)
  - `ATTIO_DEFAULT_CURRENCY`: Default currency for deal values (example: `USD`)

Note: Package rename: the README warns that the npm package is attio-mcp, not attio-mcp-server. One-line shell installers are also available but global npm install + stdio command is the canonical manual path.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
