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 Metaphor account to Claude via Composio Connect, enabling it to fetch content of recent AI research links, get metadata for top-shared tech articles, retrieve full text from specific document IDs, 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.

Connecting Metaphor to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Metaphor account

Back in Claude, ask it to connect to Metaphor or give it any Metaphor-related task.

For example, ask Claude to:

  • "Fetch content of recent AI research links"
  • "Get metadata for top-shared tech articles"
  • "Retrieve full text from specific document IDs"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Metaphor account is ready to use.

What is the Metaphor Claude Connector, and what's possible with it?

The Metaphor MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Metaphor account. It provides structured and secure access to your neural search data, so your agent can perform actions like retrieving document contents, extracting metadata, and surfacing relevant knowledge from indexed documents on your behalf.

  • Bulk document content retrieval: Fetch the full parsed HTML or text of multiple documents at once using their IDs, making research and data extraction effortless.
  • Metadata extraction and analysis: Have your agent pull structured metadata (like title, source, or date) for any set of indexed documents to power downstream tasks or summaries.
  • Context-aware content delivery: Provide your agent with in-depth context from relevant documents to inform generation, summarization, or Q&A workflows.
  • Automated research pipelines: Let the agent orchestrate the retrieval of primary sources and their contents, enabling advanced aggregation or cross-document insights.

Troubleshooting

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

The connector can show as connected, but Claude must use it in each Metaphor conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Metaphor again.

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Metaphor.

  • 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 Metaphor.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Metaphor authorization link not work?

The Composio connector is one server. Your Metaphor account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Metaphor connection.
  • Composio creates a fresh Metaphor authorization link.
  • Open that link in your browser and finish the Metaphor sign-in.

4. Why do Metaphor actions fail after they worked before?

The Metaphor connection can expire or lose permission.

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

5. How do I switch to a different Metaphor account?

Claude can manage the Metaphor connection for you.

  • Ask Claude to disconnect or delete the current Metaphor account.
  • Ask Claude to connect Metaphor again.
  • Open the new Composio authorization link for Metaphor.
  • Sign in with the other Metaphor account in the browser.
  • After the account connects, ask Claude to retry the Metaphor task.

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

The connector belongs to your Claude account, so your Metaphor connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Metaphor 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 Metaphor.

FAQ

Frequently asked questions

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

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 Metaphor tools.

Yes, absolutely. You can configure which Metaphor 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.

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 Metaphor data and credentials are handled as safely as possible.
