How to connect Inworld AI to Claude Cowork

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Inworld AI account to Cowork via Composio Connect, enabling it to generate speech for character dialogue, find available Inworld voice models, create embeddings for knowledge search, and more such actions on your behalf without compromising your account security.

4. Connect your Inworld AI account

Back in Cowork, ask the agent to connect to Inworld AI or give it any Inworld AI-related task.

For example, ask Cowork to:

  • "Generate speech for character dialogue"
  • "Find available Inworld voice models"
  • "Create embeddings for knowledge search"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Inworld AI account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Inworld AI through MCP without you sharing account credentials directly with the agent.

What is the Inworld AI MCP server, and what's possible with it?

The Inworld AI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Inworld AI account. It provides structured and secure access to speech, voices, models, and embeddings, so your agent can synthesize speech, transcribe audio, explore voices, compare models, and create text embeddings on your behalf.

  • Speech synthesis: Have your agent turn short text into spoken audio using an available Inworld voice.
  • Audio transcription: Direct your agent to transcribe short audio files and return the final text with timestamps and usage details.
  • Voice discovery and previews: Let the agent browse available voices by language or other preferences and generate MP3 previews before you choose one.
  • Model comparison: Instruct your agent to list supported models and compare their pricing, modalities, context sizes, and output limits.
  • Text embeddings: Have your agent generate a complete embedding vector for each text input using an Inworld-hosted model.
TOOLS

Supported Tools

Every Inworld AI action and event your agent gets out of the box.

Create Embeddings

Generate one complete embedding vector per input text with an Inworld-hosted embedding model.

Get Voice Preview

Generate the provider-selected, unmetered MP3 preview for a voice and return it as a downloadable file.

List Models

List Inworld-supported models and the pricing, modality, context, and output limits needed to choose a model.

List Voices

Return one page of voices available for preview or speech synthesis, with optional filtering, language selection, and sorting.

Synthesize Speech

Synthesize short text with an Inworld voice and return the complete audio as a downloadable file.

Transcribe Audio

Synchronously transcribe a short audio file and return the final transcript, timestamps, and usage.

FAQ

Frequently asked questions

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

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