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 Svix account to Claude via Composio Connect, enabling it to list all webhook endpoints for app X, create a new webhook endpoint for payments, update application rate limit to 1000/min, 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.

Connecting Svix to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Svix account

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

For example, ask Claude to:

  • "List all webhook endpoints for app X"
  • "Create a new webhook endpoint for payments"
  • "Update application rate limit to 1000/min"

It will prompt you to authenticate and authorize access.

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

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

The Svix MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Svix account. It provides structured and secure access to your webhooks infrastructure, so your agent can perform actions like managing applications, configuring endpoints, sending webhooks, and monitoring delivery attempts on your behalf.

  • Application management and automation: Ask your agent to create, update, list, or delete Svix applications, making it easy to manage webhook-enabled projects programmatically.
  • Endpoint configuration: Have your agent register, retrieve, or remove webhook endpoints for your applications, ensuring your events get delivered to the right places.
  • Webhook delivery tracking: Let your agent fetch detailed information about message delivery attempts, helping you monitor reliability and debug failed webhooks with ease.
  • Comprehensive application insights: Retrieve metadata and details for any Svix application, so your agent can surface key info or audit your webhook ecosystem.
  • Automated cleanup and maintenance: Direct your agent to delete outdated applications or endpoints, streamlining your webhook management and reducing clutter.

Troubleshooting

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

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

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

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

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

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

3. Why does the Svix authorization link not work?

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

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

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

The Svix connection can expire or lose permission.

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

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

Claude can manage the Svix connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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