# Attio MCP MCP Server

> **Attio MCP MCP Server** is a hosted, multitenant Model Context Protocol (MCP) server run by **MewCP** (https://mewcp.com), giving AI agents managed access to Attio MCP.
>
> MewCP takes care of all MCP infrastructure for you — credential storage, OAuth flows,
> token refresh, and production-grade auto-scaling — so your AI agents can connect to
> third-party services and run freely without you managing any MCP server yourself.

## Access

The gateway URL below serves your **entire MewCP toolset**, not this server on its
own. Pasting a config snippet is not enough — Attio MCP has to be in the toolset
first. In order:

1. Add Attio MCP to your toolset at https://mewcp.com/mcp/attio-mcp
2. Connect your Attio MCP account (OAuth); MewCP stores the credential and attaches it to each call
3. Add the gateway URL to your client (see Connect below). It signs in with OAuth
   the first time it connects, so there is no key to copy.

Once connected, an agent does **not** see this server's tools as top-level tools.
It sees four meta-tools and reaches everything through them:

- `search(query)` — find tools by keyword across the toolset
- `get_schema(tools)` — full description and arguments for the tools you picked
- `list_accounts(provider)` — only when one app has several connected accounts
- `call_tool(server_maskedId, tool_name, args)` — execute

So the list below is what `search` can return for this server, not a set of
callable tool names on their own.
