## Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.
This guide walks you through the easiest and most secure way to connect your Clay account to Claude via Composio Connect, enabling it to search people by email and enrich, run routine to update company records, query workspace table for leads today, and more such actions on your behalf without compromising your account security.
Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

## What is the Clay MCP server, and what's possible with it?

The Clay MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Clay account. It provides structured and secure access so your agent can perform Clay operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CLAY_CONTINUE_SEARCH` | Continue Search | Consume one next page from an existing Clay query-mode search. Each call advances Clay's server-side iterator and consumes search quota; call again only while has_more is true. |
| `CLAY_GET_CURRENT_USER` | Get Current User | Return the Clay user and workspace associated with the connected Public API key. |
| `CLAY_GET_ROUTINE_RUN_RESULTS` | Get Routine Run Results | Check progress or fetch one page of results for an existing inline Clay routine run. Returns progress while processing and an explicit next_cursor when another terminal result page is available. |
| `CLAY_GET_SEARCH_QUERY_REFERENCE` | Get Search Query Reference | Return Clay's current advanced-search field and grammar reference for composing people or company queries. |
| `CLAY_RUN_ROUTINE` | Run Routine | Start a Clay routine for 1-100 items, poll it for a bounded time, and return completed item results or the current run ID and progress. Execution may consume Clay credits and can notify an existing webhook when webhook_id is provided. |
| `CLAY_SEARCH_PEOPLE_OR_COMPANIES` | Search People or Companies | Create a Clay query-mode people or company search and consume its first result page. This advances a stateful search iterator and consumes Clay search quota; use Continue Search only while has_more is true. |

## Supported Triggers

## Troubleshooting

### 1. Why does Claude not use the Composio connector for Clay?

The connector can show as connected, but Claude must use it in each Clay conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to Clay again.

### 2. Why does Claude show an MCP server error before Clay connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Clay.
- Check that the connector URL is https://connect.composio.dev/mcp.
- Connectors run from Anthropic's cloud, so your device network is usually not the problem.
- Add the connector again from Customize > Connectors, then ask Claude to connect Clay.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the Clay authorization link not work?

The Composio connector is one server. Your Clay account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the Clay connection.
- Composio creates a fresh Clay authorization link.
- Open that link in your browser and finish the Clay sign-in.

### 4. Why do Clay actions fail after they worked before?

The Clay connection can expire or lose permission.
- Ask Claude to inspect the Clay connection.
- If the connection is unhealthy, disconnect it when Claude prompts you.
- Reconnect the Clay account and retry the action.
- If Claude shows a permission prompt, approve it before Claude changes data in Clay.
- If the action still fails with a permission error, check that the connected account has that permission in Clay itself.

### 5. How do I switch to a different Clay account?

Claude can manage the Clay connection for you.
- Ask Claude to disconnect or delete the current Clay account.
- Ask Claude to connect Clay again.
- Open the new Composio authorization link for Clay.
- Sign in with the other Clay account in the browser.
- After the account connects, ask Claude to retry the Clay task.

### 6. Why is my Clay connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Clay connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If Clay tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
- On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Clay.

## Creating MCP Server - Stand-alone vs Composio SDK

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Clay MCP?

With a standalone Clay MCP server, the agents and LLMs can only access a fixed set of Clay tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Clay and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Clay tools.

### Can I manage the permissions and scopes for Clay while using Tool Router?

Yes, absolutely. You can configure which Clay scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Clay data and credentials are handled as safely as possible.
