Chatfai is an AI platform that lets users talk to AI versions of fictional characters from books, movies, and games. It offers an engaging, interactive experience for fans to chat, roleplay, and explore creative dialogues.

3 Tools

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 Chatfai account to Claude via Composio Connect, enabling it to get details for Harry Potter character, show info about Sherlock Holmes character, fetch profile for Spider-Man character, 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 Chatfai account

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

For example, ask Claude to:

  • "Get details for Harry Potter character"
  • "Show info about Sherlock Holmes character"
  • "Fetch profile for Spider-Man character"

It will prompt you to authenticate and authorize access.

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

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

The Chatfai MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Chatfai account. It provides structured and secure access to the Chatfai platform, so your agent can browse, retrieve, and interact with AI-generated fictional characters from across media on your behalf.

  • Fetch character details by ID: Instantly retrieve comprehensive information on any public AI character by providing its unique identifier.
  • Access character backgrounds and attributes: Let your agent pull background stories, personality traits, and media origins for specific characters.
  • Enable character discovery: Use your agent to surface information about new or trending public characters in the Chatfai ecosystem.
  • Integrate character data into chat experiences: Seamlessly incorporate retrieved character info into custom conversational flows or creative projects.

Troubleshooting

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

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

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

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

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

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

3. Why does the Chatfai authorization link not work?

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

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

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

The Chatfai connection can expire or lose permission.

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

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

Claude can manage the Chatfai connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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