For example, ask Cowork to:

It will prompt you to authenticate and authorize access.

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 OnlySocial through MCP without you sharing account credentials directly with the agent.

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

The OnlySocial MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OnlySocial account. It provides structured and secure access to your connected social accounts, posts, media, and tags, so your agent can review accounts, inspect posts, manage media, and organize tags on your behalf.

  • Connected account visibility: Have your agent list connected social accounts and check their providers and authorization status.
  • Post review: Let the agent browse workspace posts and retrieve a specific post with its accounts, tags, and content versions.
  • Media library management: Direct your agent to browse images and videos, inspect file details and alt text, or upload new media for future posts.
  • Tag organization: Instruct your agent to list, create, rename, recolor, or delete tags used to organize your social content.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which OnlySocial 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 OnlySocial 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.
