## 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 Readwise Reader account to Claude via Composio Connect, enabling it to save research article to Reader inbox, list unread documents tagged machine learning, archive finished documents in Reader library, 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 Readwise Reader MCP server, and what's possible with it?

The Readwise Reader MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Readwise Reader account. It provides structured and secure access to your document library, so your agent can save, find, organize, update, and delete documents on your behalf.
- Save content for later: Have your agent save a web page or supplied HTML to your library, with optional details, a reading location, and tags.
- Find library documents: Instruct your agent to list and filter saved documents or fetch a specific document from your library.
- Organize with tags: Let the agent review the tags in your library and apply relevant tags when saving or updating documents.
- Update documents: Direct your agent to change supported details on one document or update up to 50 documents at once.
- Remove unwanted documents: Have your agent permanently delete a document you no longer want in your Reader library.

## Supported Tools

## Troubleshooting

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

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

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

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

### 3. Why does the Readwise Reader authorization link not work?

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

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

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

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

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

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

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

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

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

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Readwise Reader MCP?

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

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

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