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 Sentry account to Claude via Composio Connect, enabling it to list unresolved issues in web-app project, summarize recent errors causing production crashes, assign critical issues to oncall engineer, 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.

For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.

3. Connect your Sentry account

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

For example, ask Claude to:

  • "List unresolved issues in web-app project"
  • "Summarize recent errors causing production crashes"
  • "Assign critical issues to oncall engineer"

It will prompt you to authenticate and authorize access.

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

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

The Sentry MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sentry account. It provides structured and secure access to your organizations, projects, issues, events, and replays, so your agent can investigate errors, analyze root causes, find relevant events, and update issues on your behalf.

  • Issue search and investigation: Have your agent search grouped issues in Sentry to find the production problems that need attention.
  • Root cause analysis: Let the agent use Seer to analyze production errors and suggest specific code fixes.
  • Event and replay search: Direct your agent to search events and replays for context around reported errors and user sessions.
  • Project and organization discovery: Instruct your agent to find the Sentry organizations and projects you can access.
  • Issue updates: Have your agent change an issue's status or assign it to the right person.

Troubleshooting

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

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

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

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

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

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

3. Why does the Sentry authorization link not work?

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

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

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

The Sentry connection can expire or lose permission.

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

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

Claude can manage the Sentry connection for you.

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

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

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

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