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 Folk account to Claude via Composio Connect, enabling it to list all companies added this week, add a new company called Acme Corp, get details for person with email john@acme.com, 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.

3. Connect your Folk account

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

For example, ask Claude to:

  • "List all companies added this week"
  • "Add a new company called Acme Corp"
  • "Get details for person with email john@acme.com"

It will prompt you to authenticate and authorize access.

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

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

The Folk MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Folk account. It provides structured and secure access to your CRM workspace, so your agent can perform actions like managing contacts, organizing companies, retrieving group info, and handling custom fields on your behalf.

  • Contact management and retrieval: Let your agent list, fetch, or delete people in your workspace, ensuring your contact database stays relevant and up to date.
  • Company and organization operations: Effortlessly create new companies, retrieve details, or remove outdated organizations from your workspace via your agent.
  • Workspace group insights: Ask your agent to list workspace groups and explore available group custom fields for efficient segmentation and tracking.
  • User profile and context access: Allow your agent to pull current workspace user details, making personalized automations and actions possible.
  • Custom field exploration: Enable your agent to list and understand custom fields for groups and entity types, powering more tailored CRM workflows.

Troubleshooting

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

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

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

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

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

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

3. Why does the Folk authorization link not work?

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

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

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

The Folk connection can expire or lose permission.

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

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

Claude can manage the Folk connection for you.

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

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

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

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

FAQ

Frequently asked questions

With a standalone Folk MCP server, the agents and LLMs can only access a fixed set of Folk tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Folk 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 Folk tools.

Yes, absolutely. You can configure which Folk 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 Folk data and credentials are handled as safely as possible.
