Api Key

MiniMax is a multimodal AI platform for text, video, speech, image, music, and file workflows. Its unified APIs help developers build rich AI experiences from one service.

35 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 MiniMax account to Claude via Composio Connect, enabling it to generate a MiniMax voice narration, create a MiniMax image from text, generate a MiniMax video from storyboard, 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.

Add to Claude

Add manually

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

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 MiniMax account

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

For example, ask Claude to:

  • "Generate a MiniMax voice narration"
  • "Create a MiniMax image from text"
  • "Generate a MiniMax video from storyboard"

It will prompt you to authenticate and authorize access.

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

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

The MiniMax MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your MiniMax account. It provides structured and secure access to text generation, image creation, video generation, speech synthesis, audio transcription, voice tools, and file workflows, so your agent can generate content, create and track videos, synthesize and transcribe audio, manage voices, and upload or retrieve files on your behalf.

  • Text and image creation: Have your agent generate text with MiniMax models, count or estimate input tokens, and create images from detailed prompts.
  • Video generation and tracking: Direct your agent to create videos from text or reference media, use templates, enhance video prompts, check task progress, and retrieve finished results.
  • Speech and audio workflows: Let the agent synthesize spoken audio, start and monitor long-form speech tasks, and transcribe uploaded audio with options for timestamps, speaker separation, subtitles, and language hints.
  • Custom voice management: Instruct your agent to list available voices, design a voice from a description, clone a voice from an uploaded sample, create preview audio, or remove voices you no longer need.
  • File and generated output management: Have your agent upload files for supported MiniMax workflows, review available files, retrieve file details, download generated content, or delete files.

Troubleshooting

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

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

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

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

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

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

3. Why does the MiniMax authorization link not work?

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

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

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

The MiniMax connection can expire or lose permission.

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

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

Claude can manage the MiniMax connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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