## 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 AnyAPI.
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 AnyAPI 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 AnyAPI
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 AnyAPI to Atomic Agent

### Connect AnyAPI 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 AnyAPI. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your AnyAPI 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 AnyAPI MCP server, and what's possible with it?

The AnyAPI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your AnyAPI account. It provides structured and secure access to utility APIs for validation, currency conversion, holiday lookup, document generation, spreadsheet data, and web data, so your agent can validate information, convert currencies, check holidays, create invoices, and manage Google Sheets rows on your behalf.
- Validation and verification: Have your agent validate email addresses, phone numbers, IBANs, and VAT numbers, or find phone numbers in text with parsed details.
- Currency, tax, and holiday tools: Direct your agent to convert currencies, list exchange rates, calculate VAT, retrieve VAT rates, and check or list holidays by country and year.
- Invoice and document generation: Instruct your agent to generate a downloadable PDF invoice with seller, customer, tax, payment, locale, and line item details.
- Google Sheets management: Let the agent inspect spreadsheet documents, retrieve rows from a tab, append new rows, or delete existing rows.
- Text and location utilities: Have your agent analyze sentiment in English, Spanish, or Portuguese text, look up approximate details for an IP address, and report email or phone validation results.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ANYAPI_ANALYZE_SENTIMENT` | Analyze Sentiment | Classify the sentiment of English, Spanish, or Portuguese text and return the provider's label, score, language, and tokens. |
| `ANYAPI_CALCULATE_VAT` | Calculate VAT | Calculate the tax-inclusive total and applicable VAT details for a pre-tax amount and country, optionally considering a VAT number and state code. |
| `ANYAPI_CHECK_HOLIDAY` | Check Holiday | Return holidays AnyAPI reports for a calendar date and country; reported holiday dates can differ from the requested date. |
| `ANYAPI_CONVERT_CURRENCY` | Convert Currency | Convert a monetary amount between two currency codes using the latest available exchange rate. |
| `ANYAPI_CREATE_GOOGLE_SHEET_ROW` | Create Google Sheet Row | Append a row to a Google Sheets tab. Before calling this action, link the Google account that can access the spreadsheet inside AnyAPI. |
| `ANYAPI_DELETE_GOOGLE_SHEET_ROW` | Delete Google Sheet Row | Permanently delete an existing row from a Google Sheet tab by its row ID. Before calling this action, link the Google account that can access the spreadsheet inside AnyAPI. |
| `ANYAPI_FIND_PHONE_NUMBERS` | Find Phone Numbers | Find phone numbers in text and return each number's parsed format, validity, type, and character offsets. |
| `ANYAPI_GENERATE_BLOG_OPENGRAPH_IMAGE` | Generate Blog OpenGraph Image | Currently unavailable because AnyAPI's Chromium runtime is failing. Intended to generate a downloadable PNG OpenGraph image for a blog post from its title and author. |
| `ANYAPI_GENERATE_PDF_INVOICE` | Generate PDF Invoice | Generate and return a downloadable PDF invoice using seller, customer, tax, payment, locale, and up to one line item. |
| `ANYAPI_GET_GOOGLE_SHEET_DOCUMENT` | Get Google Sheet Document | Return a Google Sheets document's title, locale, and sheet-tab titles. Requires the AnyAPI account to have a Google account linked inside AnyAPI. |
| `ANYAPI_GET_GOOGLE_SHEET_ROWS` | Get Google Sheet Rows | Get the JSON payload for one Google Sheets tab as an object or array of row objects. AnyAPI's documentation conflicts: its example shows document metadata instead of rows, so callers must inspect the returned data shape. This requires a Google account to be linked separately inside AnyAPI in addition to the AnyAPI API key. |
| `ANYAPI_GET_VAT_RATES` | Get VAT Rates | Return the latest applicable VAT rate and charge treatment for a country and optional VAT number. |
| `ANYAPI_LIST_EXCHANGE_RATES` | List Exchange Rates | Return the latest available exchange rates for every supported currency relative to an optional base currency, or AnyAPI's default when omitted. |

## 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

None listed.

## Conclusion

### Use AnyAPI from Atomic Agent
With your account connected, ask Atomic Agent to work with AnyAPI 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 AnyAPI MCP?

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

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

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