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 Proxiedmail account to Claude via Composio Connect, enabling it to list all your current proxy email addresses, create a webhook to receive new emails, update a proxy binding to forward to a new address, 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.

3. Connect your Proxiedmail account

Back in Claude, ask it to connect to Proxiedmail or give it any Proxiedmail-related task.

For example, ask Claude to:

  • "List all your current proxy email addresses"
  • "Create a webhook to receive new emails"
  • "Update a proxy binding to forward to a new address"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Proxiedmail account is ready to use.

What is the Proxiedmail Claude Connector, and what's possible with it?

The Proxiedmail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Proxiedmail account. It provides structured and secure access to your privacy-focused email services, so your agent can create proxy email addresses, manage bindings, receive emails via webhooks, and update proxy settings automatically.

  • Create unique webhook receivers: Instantly set up custom webhook endpoints for capturing incoming emails through Proxiedmail, making it easy for your agent to receive messages securely.
  • Fetch and manage proxy bindings: Ask your agent to retrieve a list of all your active proxy email bindings, helping you monitor and organize your privacy-layered inboxes.
  • Update proxy binding settings: Let your agent modify existing proxy bindings, such as updating forwarding addresses or tweaking configuration details as your needs change.
  • Seamless API token management: Have your agent securely obtain and refresh Proxiedmail API tokens for seamless, uninterrupted access to your account and services.

Troubleshooting

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

The connector can show as connected, but Claude must use it in each Proxiedmail conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Proxiedmail again.

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Proxiedmail.

  • 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 Proxiedmail.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Proxiedmail authorization link not work?

The Composio connector is one server. Your Proxiedmail account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Proxiedmail connection.
  • Composio creates a fresh Proxiedmail authorization link.
  • Open that link in your browser and finish the Proxiedmail sign-in.

4. Why do Proxiedmail actions fail after they worked before?

The Proxiedmail connection can expire or lose permission.

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

5. How do I switch to a different Proxiedmail account?

Claude can manage the Proxiedmail connection for you.

  • Ask Claude to disconnect or delete the current Proxiedmail account.
  • Ask Claude to connect Proxiedmail again.
  • Open the new Composio authorization link for Proxiedmail.
  • Sign in with the other Proxiedmail account in the browser.
  • After the account connects, ask Claude to retry the Proxiedmail task.

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

The connector belongs to your Claude account, so your Proxiedmail connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Proxiedmail 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 Proxiedmail.

FAQ

Frequently asked questions

With a standalone Proxiedmail MCP server, the agents and LLMs can only access a fixed set of Proxiedmail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Proxiedmail and many other apps based on the task at hand, all through a single MCP endpoint.

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 Proxiedmail tools.

Yes, absolutely. You can configure which Proxiedmail 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.

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 Proxiedmail data and credentials are handled as safely as possible.
