Debugger MCP Server

A comprehensive development companion tool that provides real-time debugging, code quality monitoring, and AI-enhanced insights for React/Next.js applications via MCP. Exposed over MCP by the debugger mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Its toolset

Everything the assistant can do here goes through one of these:

• get-debug-session — Get current debugging session information
• get-errors — Get current errors and exceptions
• get-violations — Get code quality rule violations
• analyze-complexity — Analyze complexity metrics for a file
• get-performance — Get performance metrics and insights
• manage-breakpoints — Set, remove, and manage debugging breakpoints
• update-config — Update debugger configuration
• Debugging — The Debugging tool exposed by this server

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Debugger MCP's toolset — get-debug-session, get-errors, get-violations and 5 more — is a fair guide to whether it matches your workflow. It is maintained by Phoenixrr2113; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the debugger mcp mcp server does with a few real requests.
