## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including TinyFish.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a TinyFish account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to TinyFish
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect TinyFish to Atomic Agent

### Connect TinyFish to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in TinyFish. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your TinyFish account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## 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

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

## Conclusion

### Use TinyFish from Atomic Agent
With your account connected, ask Atomic Agent to work with TinyFish in natural language. You can connect more apps through the same Composio integration as you need them.

## 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 Atomic Agent?

Yes, you can. Atomic Agent 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.
