## 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 AnyAPI account to Claude via Composio Connect, enabling it to convert USD prices to EUR for invoices, check public holidays before scheduling client meetings, validate customer email addresses before sending campaigns, 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 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_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. |

## Troubleshooting

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

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

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for AnyAPI.
- 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 AnyAPI.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

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

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

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

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

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

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

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

The connector belongs to your Claude account, so your AnyAPI connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If AnyAPI 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 AnyAPI.

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

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

## 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 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 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.
