delve-mcp
MCP server for Delve debugger integration
This is a TypeScript-based MCP server that provides a complete interface to the Delve debugger for Go programs. It implements all major Delve commands and capabilities through MCP tools.
Features
Resources
List and access debug sessions via
delve://URIsEach session has metadata about its type, target, and port
JSON representation for session details and state
Tools
Debug, trace, and analyze Go programs with:
Debug commands (
debug,attach,exec,test)Core dump analysis
Program tracing
Replay debugging with
rrDAP server support
Breakpoint management with conditions
Execution control (
continue,step,next)Variable inspection and evaluation
Backend selection (
native,lldb,rr)Logging configuration
Session management
Environment Setup
The server requires:
Go installed with Delve (
go install github.com/go-delve/delve/cmd/dlv@latest)For replay functionality: Mozilla
