## Introduction

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 TinyFish MCP account to Cowork via Composio Connect, enabling it to summarize top Hacker News stories, check pricing on competitor websites, fill website forms from spreadsheet, and more such actions on your behalf without compromising your account security.

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

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

The TinyFish MCP MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your TinyFish MCP account. It provides structured and secure access so your agent can perform TinyFish MCP operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `TINYFISH_MCP_CANCEL_RUN` | Cancel run | Cancels a running or pending automation run by its ID. Idempotent: if the run is already in a terminal state (COMPLETED, FAILED, CANCELLED), returns the current status without error. Only PENDING and RUNNING runs will be actively cancelled. |
| `TINYFISH_MCP_DISCOVER_RUN` | Discover run | Discovers the currently running automation for this session. Returns runId if a run is active, or null if not yet started. |
| `TINYFISH_MCP_GET_RUN` | Get run | Retrieves details of a specific automation run by its ID. Returns status, result, error, and other metadata. IMPORTANT: Call this after run_web_automation errors or times out — the run is likely still executing. If you do not have a run_id, use list_runs to find it. Also use this to poll for completion after run_web_automation_async. Runs typically take a few minutes. Wait 30-60 seconds between polls. |
| `TINYFISH_MCP_GET_STEPS` | Get steps | Retrieves the steps taken during an automation run, including screenshots. |
| `TINYFISH_MCP_LIST_RUNS` | List runs | Lists automation runs with optional filtering by status and pagination support. Returns an array of runs with their details. Use this to find a recently created run when you do not have its run_id (e.g., after run_web_automation timed out before returning a run_id). Filter by status=RUNNING to find active runs. |
| `TINYFISH_MCP_POLL_STATUS` | Poll status | Polls the current status of an automation run. Returns status, step, progress, and other metadata. |
| `TINYFISH_MCP_RUN_WEB_AUTOMATION` | Run web automation | Executes web automation given a URL and a Natural Language description of the automation goal to be performed. Automation is mostly focused around navigating complex web pages and extracting data from web pages. Include _meta.progressToken in your request to receive progress notifications. WARNING: This tool may take several minutes. If it errors or times out, the run is STILL EXECUTING on the server. DO NOT call this tool again or call run_web_automation_async — both would create a duplicate run. Instead: if you have a run_id from progress notifications, call get_run. If you have no run_id, call list_runs to find it. Only create a new run after confirming the previous one finished. |
| `TINYFISH_MCP_RUN_WEB_AUTOMATION_ASYNC` | Run web automation async | Starts a NEW web automation run asynchronously and returns a run_id immediately without waiting for completion. WARNING: Do NOT use this to retry a failed run_web_automation call — that run is still executing. Use get_run or list_runs to check its status instead. Only use this tool for genuinely new tasks. Workflow: 1) Call this tool to get a run_id. 2) Wait 30-60 seconds. 3) Call get_run with the run_id to check status. 4) Repeat step 2-3 until status is COMPLETED, FAILED, or CANCELLED. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and TinyFish MCP MCP?

With a standalone TinyFish MCP MCP server, the agents and LLMs can only access a fixed set of TinyFish MCP tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from TinyFish MCP and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

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 TinyFish MCP tools.

### Can I manage the permissions and scopes for TinyFish MCP while using Tool Router?

Yes, absolutely. You can configure which TinyFish MCP 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.

### How safe is my data with Composio Tool Router?

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 TinyFish MCP data and credentials are handled as safely as possible.
