## Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.
This guide walks you through the easiest and most secure way to connect your TinyFish account to Claude via Composio Connect, enabling it to extract article content from example.com, start a browser session and scrape results, run scheduled site checks and save snapshots, and more such actions on your behalf without compromising your account security.
Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

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

The TinyFish 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 account. It provides structured and secure access so your agent can perform TinyFish operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `TINYFISH_CANCEL_PROFILE_SETUP_SESSION` | Cancel Profile Setup Session | Cancel a Browser Context Profile setup session and permanently discard its unsaved cookies and browser storage. |
| `TINYFISH_CANCEL_RUNS` | Cancel Runs | Idempotently cancel one or up to 100 asynchronous or SSE runs. Active cancellation is irreversible; synchronous runs cannot be cancelled, and already-terminal runs are returned with their actual status. |
| `TINYFISH_CREATE_BROWSER_SESSION` | Create Browser Session | Create an isolated TinyFish remote browser session and return its CDP connection URL. This action starts billable browser infrastructure: TinyFish meters Browser usage until the session ends or becomes inactive. You must call Terminate Browser Session with the returned session_id immediately after browser work finishes, including after failures, to stop further usage charges. Creation can return before startup navigation completes. |
| `TINYFISH_CREATE_PROFILE` | Create Profile | Create a reusable Browser Context Profile for cookies and browser storage; this changes persistent account state. |
| `TINYFISH_DELETE_PROFILE` | Delete Profile | Permanently delete a Browser Context Profile and all browser state saved in it. This action cannot be undone. |
| `TINYFISH_DELETE_PROFILE_DOMAIN` | Delete Profile Domain | Permanently remove saved cookies and browser storage for one domain from a Browser Context Profile. This action cannot be undone. |
| `TINYFISH_FETCH_URLS` | Fetch URLs | Render and extract content from 1-10 URLs in one provider-native batch. Always inspect both results and errors because HTTP 200 can contain successful pages and per-URL failures together. |
| `TINYFISH_GET_PROFILE` | Get Profile | Get one Browser Context Profile and its saved-domain metadata. |
| `TINYFISH_GET_RUNS` | Get Runs | Get summary records for 1-100 TinyFish automation run IDs in one request. The response separately reports IDs that were not found or are not owned. |
| `TINYFISH_GET_WALLET` | Get Wallet | Get the TinyFish wallet balance, auto-reload and pending-top-up state, and current Agent and Browser rates. Monetary values are returned as exact decimal strings. Legacy-credit accounts report FEATURE_NOT_AVAILABLE rather than an authentication failure. |
| `TINYFISH_LIST_PROFILES` | List Profiles | List Browser Context Profiles available to the connected TinyFish account. Use the returned IDs when attaching or managing reusable browser state. |
| `TINYFISH_LIST_RESEARCH_RUNS` | List Research Runs | List saved TinyFish research runs with optional status, query, date, and sort filters, returning one cursor-controlled page. |
| `TINYFISH_LIST_RUNS` | List Runs | List automation runs with optional status, goal, date, and sort filters, returning one cursor-controlled page. |
| `TINYFISH_LIST_USAGE` | List Usage | List one page of Search, Fetch, or Browser usage history. Search and Fetch usage reads are free; Browser usage requires the paid Browser service. |
| `TINYFISH_LIST_VAULT_CONNECTIONS` | List Vault Connections | List display-safe metadata for password-manager vaults connected to TinyFish. Credentials and secret values are excluded. |
| `TINYFISH_LIST_VAULT_ITEMS` | List Vault Items | List display-safe metadata for items synchronized from password-manager vaults connected to TinyFish. Secret field values are never returned. |
| `TINYFISH_SAVE_PROFILE_SETUP_SESSION` | Save Profile Setup Session | Persist cookies and browser storage from a completed setup session into a Browser Context Profile, then clean up the temporary session. Persisted state and successful session cleanup cannot be undone. The response retains domain-level skips and failures plus cleanup status so partial success remains visible. |
| `TINYFISH_SEARCH_WEB` | Search Web | Search live web pages, news, or research papers with domain and time filters, optionally fetching result pages inline, and return exactly one caller-selected zero-based result page. |
| `TINYFISH_START_PROFILE_SETUP_SESSION` | Start Profile Setup Session | Start a billable temporary remote browser session for establishing login state in a Browser Context Profile. The returned browser state is not saved automatically: after setup, always call Save Profile Setup Session to persist it or Cancel Profile Setup Session to discard it and tear down the session. |
| `TINYFISH_SYNC_VAULT_ITEMS` | Sync Vault Items | Refresh display-safe item metadata from all password-manager vaults already connected to TinyFish. Synchronization can add, update, or remove mirrored items. Returns synchronization counts and allowlisted item metadata without credential or secret values. |
| `TINYFISH_TERMINATE_BROWSER_SESSION` | Terminate Browser Session | Idempotently terminate a remote TinyFish browser session to stop further browser usage charges. Already-ended sessions are also successful. |
| `TINYFISH_UPDATE_PROFILE` | Update Profile | Rename a Browser Context Profile or change its default and proxy-country settings. Omitted fields remain unchanged. |
| `TINYFISH_UPLOAD_PROFILE_STATE` | Upload Profile State | Upload cookies and local or session storage directly into a Browser Context Profile. This changes persistent login state and may transmit authentication secrets; call it only with the credential owner's explicit authorization. TinyFish provides no rollback endpoint, so restoring prior state requires a caller-held copy or deleting the affected domains. |

## Troubleshooting

### 1. Why does Claude not use the Composio connector for TinyFish?

The connector can show as connected, but Claude must use it in each TinyFish conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to TinyFish again.

### 2. Why does Claude show an MCP server error before TinyFish connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for TinyFish.
- Check that the connector URL is https://connect.composio.dev/mcp.
- Connectors run from Anthropic's cloud, so your device network is usually not the problem.
- Add the connector again from Customize > Connectors, then ask Claude to connect TinyFish.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the TinyFish authorization link not work?

The Composio connector is one server. Your TinyFish account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the TinyFish connection.
- Composio creates a fresh TinyFish authorization link.
- Open that link in your browser and finish the TinyFish sign-in.

### 4. Why do TinyFish actions fail after they worked before?

The TinyFish connection can expire or lose permission.
- Ask Claude to inspect the TinyFish connection.
- If the connection is unhealthy, disconnect it when Claude prompts you.
- Reconnect the TinyFish account and retry the action.
- If Claude shows a permission prompt, approve it before Claude changes data in TinyFish.
- If the action still fails with a permission error, check that the connected account has that permission in TinyFish itself.

### 5. How do I switch to a different TinyFish account?

Claude can manage the TinyFish connection for you.
- Ask Claude to disconnect or delete the current TinyFish account.
- Ask Claude to connect TinyFish again.
- Open the new Composio authorization link for TinyFish.
- Sign in with the other TinyFish account in the browser.
- After the account connects, ask Claude to retry the TinyFish task.

### 6. Why is my TinyFish connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your TinyFish connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If TinyFish tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
- On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect TinyFish.

## Creating MCP Server - Stand-alone vs Composio SDK

The TinyFish MCP server connects Claude Web, Desktop, and Cowork to your TinyFish account through Composio. Once connected, Claude can use the available TinyFish tools and triggers to complete tasks on your behalf.

## Frequently Asked Questions

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

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

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

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