## 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 Ideal Postcodes account to Cowork via Composio Connect, enabling it to lookup address for SW1A 1AA, cleanse and standardize 100 addresses, validate postcode and geocode coordinates, and more such actions on your behalf without compromising your account security.

## Also integrate Ideal Postcodes with

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

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `IDEALPOSTCODES_FIND_ADDRESS_SUGGESTIONS` | Find Address Suggestions | Return ranked address suggestions for a partial address without resolving them; resolving a selected suggestion is a separate paid lookup. |
| `IDEALPOSTCODES_FIND_PLACE_SUGGESTIONS` | Find Place Suggestions | Return ranked country, city, and administrative-area suggestions without resolving them; resolving a selected place is a separate paid lookup. |
| `IDEALPOSTCODES_GET_ADDRESS_BY_IDENTIFIER` | Get Address by Identifier | Retrieve a UK address by UDPRN or UMPRN. This consumes a paid lookup, and UMPRN requires the optional Multiple Residence dataset. |
| `IDEALPOSTCODES_LOOKUP_POSTCODE` | Lookup Postcode | Return addresses at a UK postcode, or an Irish Eircode when enabled; successful results consume paid lookups. |
| `IDEALPOSTCODES_RESOLVE_ADDRESS_SUGGESTION` | Resolve Address Suggestion | Resolve an address suggestion ID to a complete GBR or USA address. This consumes a paid lookup, and USA resolution requires an enabled USA dataset. |
| `IDEALPOSTCODES_RESOLVE_PLACE` | Resolve Place | Resolve a place suggestion ID to full geography and coordinates. This consumes a paid lookup. |
| `IDEALPOSTCODES_SEARCH_ADDRESSES` | Search Addresses | Search complete UK address records by text, filters, or coordinates; successful results consume paid lookups. |
| `IDEALPOSTCODES_VALIDATE_ADDRESS` | Validate Address | Match and standardize a GBR or USA address with confidence details. This consumes a paid lookup, and USA verification requires the optional USPS CASS dataset. |
| `IDEALPOSTCODES_VALIDATE_CONTACT` | Validate Contact | Validate an email address or international phone number using an optional paid dataset enabled on the connected Ideal Postcodes API key. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Ideal Postcodes MCP?

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

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

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