Sentry MCP Server

Overview

The Sentry MCP Server provides a secure way of bringing Sentry's full issue context into systems that are able to leverage the Model Context Protocol (MCP). Sentry hosts and manages a remote MCP server, which you can connect to and leverage centrally. With the MCP, you can:

• Access Sentry issues and errors
• Search for errors in specific files
• Query projects and organizations
• List and create Sentry DSN's for projects
• Invoke Seer to automatically fix issues and retrieve the status and details of an issue fix

The Sentry MCP Server includes support for modern MCP features:

• Remote hosted (preferred) or local STDIO mode - The hosted version provides lower friction and always includes the latest functionality and stability
• OAuth support - Authenticate using your existing Sentry organization for seamless access to your projects
• Streamable HTTP with graceful SSE fallback - Automatic fallback ensures compatibility across different clients
• 16+ tool calls and prompts - Comprehensive toolset for bringing Sentry context into LLM interactions

Getting Started

OAuth Configuration (Recommended)

For clients that support OAuth, you can use the streamlined configuration that provides automatic authentication:

{
  "mcpServers": {
    "Sentry": {
      "url": "https://mcp.sentry.dev/mcp"
    }
  }
}

This configuration:

• Enables OAuth authentication with your Sentry organization
• Uses Streamable HTTP transport with automatic SSE fallback
• Provides access to all 16+ available tools
• Automatically handles authentication and session management

With OAuth configuration, you'll be prompted to:

1. Accept the OAuth authorization
2. Login via your existing Sentry organization
3. Grant access to the necessary permissions

Once authenticated, you'll see the tools become available in your MCP client.

Remote MCP Configuration (Legacy)

For clients that don't support OAuth, you can continue using the existing Remote MCP endpoint configuration:

{
  "mcpServers": {
    "Sentry": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://mcp.sentry.dev/mcp"]
    }
  }
}

Local STDIO Mode

Alternatively, if you don't want the Remote-MCP server, you can run the MCP Server locally in STDIO mode by following the instructions in the README. This is particularly useful for self-hosted Sentry installations.

To use STDIO mode, you'll need a Sentry User Auth Token with the following scopes:

• org:read
• project:read
• project:write
• team:read
• team:write
• event:write

Launch the STDIO transport:

npx @sentry/mcp-server@latest --access-token=sentry-user-token --host=sentry.example.com

You can also use environment variables:

SENTRY_ACCESS_TOKEN=your-token
SENTRY_HOST=your-sentry-host

mcp.sentry.dev (live demo)

The Sentry MCP page provides a simple way to configure and test the MCP server. From this web client you can authenticate with your Sentry organization and access a hosted MCP server for testing.

Available Tools

The Sentry MCP Server provides comprehensive tools for interacting with Sentry data:

Core Tools

• Organizations: List and query organization information
• Projects: Find, list, and create projects
• Teams: Manage and query team information
• Issues: Access issue details, search, and analyze problems
• DSNs: List and create Data Source Names for projects

Analysis Tools

• Error Searching: Find errors in specific files or across projects
• Issue Analysis: Detailed issue investigation with context
• Seer Integration: Invoke Sentry's AI agent for root cause analysis and automated fixes

Advanced Features

• Release Management: Query and analyze release information
• Performance Monitoring: Access transaction and performance data
• Custom Queries: Execute complex searches across Sentry data

Example Usage

Here are some example prompts you can use with the Sentry MCP:

• Tell me about the issues in my project-name
• Check Sentry for errors in components/UserProfile.tsx and propose solutions
• Diagnose issue PROJECT-123 and propose solutions
• Create a new project in Sentry for new-service-name and setup local instrumentation
• Use Sentry's Seer to analyze and propose a solution for issue PROJECT-456
• Show me the most recent releases for my organization
• Find all unresolved crashes in my React Native app

Verified Clients

The Sentry MCP Server has been verified to work in:

Claude for Desktop

Access developer tools via CMD + , → Developer → Edit Config → edit the claude_desktop_config.json file

Claude.ai

Navigate to Settings → Profile → Scroll to Integrations, select Add More, and add the Sentry MCP server URL https://mcp.sentry.dev/mcp

Claude Code

Since recently reaching 1.0, Claude Code has native support for remote hosted MCP servers. From your cli enter claude mcp add --transport http sentry https://mcp.sentry.dev/mcp and then access Claude Code with claude.

Once in, you'll be prompted to authenticate with OAuth to Sentry.

Cursor

Available via Cursor → Settings → Cursor Settings → MCP following the promps to configure Sentry MCP. Cursor 1.0+ includes enhanced MCP support with OAuth and Streamable HTTP.

You can still edit the mcp.json file manually if you prefer.

VS Code and GitHub Copilot

Add the server using CMD+Shift+P and selecting MCP: Add Server

Windsurf

Configure via the Configure MCP option in Cascade (CMD + L)

Other Clients

The Sentry MCP Server follows standard MCP protocols and should work with any client that supports:

• OAuth authentication (recommended)
• Remote MCP servers
• SSE or Streamable HTTP transport

Integration with Seer

The Sentry MCP Server provides seamless integration with Seer, Sentry's AI agent. You can:

• Trigger Seer Analysis: Initiate automated root cause analysis for issues
• Get Fix Recommendations: Receive AI-generated solutions for bugs and performance issues
• Monitor Fix Status: Track the progress of Seer's analysis and implementation

Note: MCP and Seer are complementary tools. MCP brings Sentry context into your LLM, while Seer is purpose-built for deep issue analysis and automated debugging. You can use MCP to invoke Seer for complex debugging workflows.

Troubleshooting

Common Issues

OAuth Authentication Problems

• Ensure your client supports OAuth authentication
• Try the legacy Remote MCP configuration if OAuth isn't working
• Check that you have the necessary permissions in your Sentry organization

Connection Issues

• Verify the MCP server URL is correct: https://mcp.sentry.dev/mcp
• For legacy setups, use: https://mcp.sentry.dev/sse
• Check your client's MCP configuration syntax

Missing Tools

• Ensure authentication completed successfully
• Verify your Sentry organization access
• Check for any error messages in your client's console
