4. Connect your Gradium account

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

For example, ask Cowork to:

  • "Generate speech for onboarding welcome script"
  • "Transcribe customer call with speaker labels"
  • "Create pronunciation guide for product names"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Gradium 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 Gradium through MCP without you sharing account credentials directly with the agent.

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

The Gradium MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gradium account. It provides structured and secure access to your voice catalog, pronunciation dictionaries, credit balance, and usage data, so your agent can browse voices, manage pronunciation rules, check credits, and review usage on your behalf.

  • Voice discovery: Have your agent list available custom and public voices, then retrieve details about a selected voice.
  • Pronunciation dictionary management: Let the agent create language-specific pronunciation dictionaries, add rewrite rules, and update existing dictionaries.
  • Pronunciation dictionary review and cleanup: Direct your agent to list or inspect pronunciation dictionaries and delete ones you no longer need.
  • Credits and usage tracking: Instruct your agent to check your current credit balance, billing period details, and aggregate usage across sessions, messages, text, and audio duration.

FAQ

Frequently asked questions

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

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

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
