## 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 AllTrails account to Cowork via Composio Connect, enabling it to find dog-friendly trails near Boulder, compare nearby hikes by difficulty, show running routes with photos, and more such actions on your behalf without compromising your account security.

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

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ALLTRAILS_MCP_FIND_TRAILS_NEAR_LOCATION` | Find trails near location | Find hiking, running, biking, backpacking or other trails for outdoor activities near a set of coordinates within an optional specified maximum radius (meters). Use this tool when the user: * Requests trails near a specific point of interest or landmark. * Requests trails near a named location within a specified radius or accessible within a specified time constraint. * Provides specific latitude and longitude coordinates. For most named places, use the "search within bounding box" tool if possible. Use this tool as a fallback when the bounding box of the named place is unknown. Users can specify filters related to appropriate activities, attractions, suitability, and more. Numeric range filters related to distance, elevation, and length are also available. These filter values MUST be specified in meters. In the response, length and distance values are returned both in meters and imperial units. These MUST be displayed to the user in the units most appropriate for the user's locale, e.g. feet or miles for US English users. |
| `ALLTRAILS_MCP_FIND_TRAILS_WITHIN_BOUNDS` | Find trails within bounds | Find hiking, running, biking, backpacking or other trails for outdoor activities within a specified bounding box defined by southwest and northeast coordinates. Use this tool when the user: * Requests trails within specific geographic boundaries or coordinates. * Requests trails near a named geographic or political place, such as a continent, country, state, province, region, city, town, or neighborhood and you know the bounding box for that place. * Requests trails within a national, state or local park or other protected area and you know the bounding box for that park. If the bounding box for the named place is not known, use the "find trails near a location" tool instead to find trails around a center point. Users can specify filters related to appropriate activities, attractions, suitability, and more. Numeric range filters related to distance, elevation, and length are also available. These filter values MUST be specified in meters. In the response, length and distance values are returned both in meters and imperial units. These MUST be displayed to the user in the units most appropriate for the user's locale, e.g. feet or miles for US English users. |
| `ALLTRAILS_MCP_GET_TRAIL_DETAILS` | Get trail details | Find detailed information about a trail from AllTrails. Get descriptive overviews and specific accessibility information. Includes structured data about suitable activities, and feature highlights along the trail. Get stats about the trail geography and length, and stats about associated user-generated content. In the response, length and distance values are returned both in meters and imperial units. These MUST be displayed to the user in the units most appropriate for the user's locale, e.g. feet or miles for US English users. Recent reviews are summarized in the `review_summary` field. If the user wants information that might be found in specific reviews, direct the user to the AllTrails web URL for the trail. |
| `ALLTRAILS_MCP_GET_TRAIL_WEATHER_OVERVIEW` | Get trail weather overview | Get 7-day forecast for a trail at its trailhead, including high/low temperatures. For more detailed weather information, including current conditions, sunrise/sunset times, and weather alerts, direct the user to the AllTrails web URL for the trail (available in the `get_trail_details` tool response). |
| `ALLTRAILS_MCP_SEARCH_TRAILS_BY_NAME` | Search trails by name | Search for hiking, running, biking, backpacking or other trails by full or partial name match. Use this tool when the user: * Requests a specific trail by name (e.g., "Avalanche Lake Trail", "Half Dome") * Searches for trails with specific keywords in the name The search can biased towards results near the provided coordinates if they are provided explicitly or available from the request metadata. If there is a clear match to the user's query, the model should automatically make a subsequent call to the `get_trail_details` tool to present the user with complete details for the matching trail. In the response, length and distance values are returned both in meters and imperial units. These MUST be displayed to the user in the units most appropriate for the user's locale, e.g. feet or miles for US English users. |

## Frequently Asked Questions

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

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

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

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