Sentry MCP MCP Server

sentry-mcp

A fast, lightweight MCP server for Sentry, written in Rust.

Why sentry-mcp?

Compared to the official Node.js server:

• Memory: 10x less RAM usage
• Startup: instant cold start
• Disk: single binary, no runtime dependencies
• Tokens: fewer tools = smaller tool list in context

Features

This MCP server provides tools to interact with Sentry's API:

• get_issue_details - Retrieve detailed information about a Sentry issue including metadata, tags, stacktraces, and optionally a specific event
• get_trace_details - Retrieve trace details including span tree and timing information for distributed tracing analysis
• search_issue_events - Search events within an issue using Sentry's query syntax

Installation

From crates.io:

cargo install sentry-mcp

From GitHub:

cargo install --git https://github.com/utapyngo/sentry-mcp-rs.git

Or with mise:

mise use -g github:utapyngo/sentry-mcp-rs

The binary will be installed as sentry-mcp.

Configuration

Required environment variables:

• SENTRY_AUTH_TOKEN - Your Sentry API authentication token
• SENTRY_HOST - Your Sentry instance hostname (e.g., sentry.io)

Optional:

• SOCKS_PROXY - SOCKS5 proxy URL (e.g., socks5://127.0.0.1:1080)
