## About

Attio's hosted MCP server connects an AI assistant to your Attio CRM workspace. It can look up people, companies and deals, work with lists, add notes and comments, create tasks, and search meeting recordings and transcripts. The docs also list tools for emails, workspace info, reporting and SQL.

It runs as a remote streamable HTTP endpoint at https://mcp.attio.com/mcp. You sign in with your Attio account through OAuth, so no API key is needed. According to the docs, read operations are auto-approved and write operations ask for confirmation.

## What it can do

- Look up contacts and companies and filter records by attributes
- Create and update records across Attio objects
- Work with lists and pipeline stages
- Log notes and comments on records
- Create follow-up tasks with deadlines
- Search call recordings, transcripts and meeting notes

## Example prompts

- "Find the decision makers at Acme in Attio and list their email addresses."
- "Log a note on the Globex deal summarizing today's call."
- "Create a follow-up task for next Friday on the Initech record."
- "Show deals in the negotiation stage in my Attio workspace."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http attio https://mcp.attio.com/mcp
```

2. Start Claude Code, type `/mcp`, pick **attio** and choose **Authenticate**. A browser window opens for the Attio sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Attio** and paste this URL:

```url
https://mcp.attio.com/mcp
```

3. Click **Add**, then **Connect**, and sign in when Attio asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Attio&connectorUrl=https%3A%2F%2Fmcp.attio.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.attio.com/mcp` and click **Add**.

3. Click **Connect** and sign in when Attio asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://mcp.attio.com/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Attio to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=attio&config=eyJ1cmwiOiJodHRwczovL21jcC5hdHRpby5jb20vbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "attio": {
      "url": "https://mcp.attio.com/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=attio&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.attio.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"attio","type":"http","url":"https://mcp.attio.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "attio": {
      "type": "http",
      "url": "https://mcp.attio.com/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "attio": {
      "serverUrl": "https://mcp.attio.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add attio --url https://mcp.attio.com/mcp
codex mcp login attio
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.attio]
url = "https://mcp.attio.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http attio https://mcp.attio.com/mcp
```

Then, inside Gemini CLI, run `/mcp auth attio` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "attio": {
      "type": "http",
      "url": "https://mcp.attio.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.attio.com/mcp`.
