4. Connect your Transloadit account

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

For example, ask Cowork to:

  • "List recent Transloadit assembly failures"
  • "Convert uploaded videos to MP4"
  • "Check file processing status by assembly"

It will prompt you to authenticate and authorize access.

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

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

The Transloadit MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Transloadit account. It provides structured and secure access to your file-processing workflows, so your agent can start processing jobs, monitor progress, review results, cancel active work, and retry failed jobs on your behalf.

  • Start file-processing workflows: Have your agent launch a workflow from configured processing steps or an existing template, with local files included when needed.
  • Monitor processing progress: Let the agent check a workflow’s latest state, uploaded files, warnings, and processing results.
  • Find previous workflows: Instruct your agent to list recent workflows and narrow them by state, date range, or keywords.
  • Cancel active processing: Direct your agent to stop a running workflow and any file upload still in progress.
  • Recover jobs and resend notifications: Have your agent retry a crashed workflow while its input files remain available, or resend the result notification for completed work.
TOOLS

Supported Tools

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

Cancel Assembly

Cancel a running Assembly and any upload still in progress.

Create Assembly

Start a Transloadit file-processing Assembly from validated inline Steps or an existing Template, optionally uploading up to 10 local files with a 20 MiB aggregate direct-upload limit.

Get Assembly Status

Retrieve the latest state, uploads, warnings, and results for one Assembly.

List Assemblies

Return one page of Assemblies in descending creation order, optionally filtered by state, date range, or keywords.

Replay Assembly

Retry a crashed Assembly while its original input files remain recoverable, optionally reparsing its Template.

Replay Assembly Notification

Resend a completed Assembly's result notification to the notify_url configured on that Assembly.

FAQ

Frequently asked questions

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

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