Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

    }
  }
}

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

~/.continue/config.json

O Continue usa um array de objetos de servidor em vez de um map.

}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

claude mcp add mcp-windbg -- TODO 'See README: https://github.com/svnscha/mcp-windbg'

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Casos de uso

Usos do mundo real: mcp-windbg

How to analyze a Windows crash dump with AI assistance

👤 Windows developers investigating application crashes ⏱ ~30 min intermediate

Quando usar: You have a .dmp file from a crash and need to understand what happened.

Pré-requisitos

Windows with Debugging Tools/WinDbg — Install from Microsoft Store or Windows SDK
mcp-windbg installed — pip install mcp-windbg

Fluxo

Open the dump

Open the crash dump at C:\dumps\app_crash.dmp. Run !analyze -v and explain what caused the crash.✓ Copiado

→ Detailed crash analysis with exception type, faulting module, and call stack
Investigate the call stack

Show me the full call stack of the faulting thread. What was the application doing when it crashed?✓ Copiado

→ Annotated call stack with function descriptions
Check for patterns

Run !locks and !heap -s. Is there a deadlock or heap corruption?✓ Copiado

→ Lock/heap analysis results with interpretation

Resultado: Root cause of the crash identified with a clear explanation.

Armadilhas

Missing symbol files — Set up a symbol path: .sympath SRV*c:\symbols*https://msdl.microsoft.com/download/symbols

Combine com: filesystem

Batch analyze multiple crash dumps to find patterns

👤 Support engineers investigating recurring crashes ⏱ ~45 min intermediate

Quando usar: You have multiple crash dumps from the same application and need to find common patterns.

Pré-requisitos

mcp-windbg and WinDbg installed — pip install mcp-windbg

Fluxo

List available dumps

List all crash dump files in C:\dumps\. How many are there and when were they created?✓ Copiado

→ List of dumps with timestamps
Analyze and compare

Open each dump, run !analyze -v, and give me a summary comparing the crash reasons. Are they the same bug or different issues?✓ Copiado

→ Comparison table showing crash type, module, and stack similarity

Resultado: Pattern analysis across multiple crashes to prioritize fixes.

Armadilhas

Large dumps take time to analyze — Start with minidumps if available — they're faster to open

Combine com: filesystem

mcp-windbg + filesystem

Export crash analysis reports to files for bug tracking

Analyze all dumps in C:\dumps\ and write a summary report to C:\reports\crash-analysis.md.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
list_windbg_dumps	directory: str	Discover crash dump files in a directory
open_windbg_dump	dump_path: str	Open and analyze a crash dump
close_windbg_dump	session_id: str	Close a dump analysis session
open_windbg_remote	connection_string: str	Connect to a remote debug target
run_windbg_cmd	session_id: str, command: str	Execute any WinDbg command in a session
send_ctrl_break	session_id: str	Break into a running debug target

Custo e limites

O que custa rodar

Cota de API: N/A — fully local
Tokens por chamada: 300–3000 tokens per command output
Monetário: Free — WinDbg is free from Microsoft
Dica: Use targeted WinDbg commands (!analyze -v, k) instead of verbose outputs to reduce tokens.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: N/A for local dumps. Remote debugging may require authentication.

Saída de dados: Local analysis only. Symbol downloads go to Microsoft's symbol server.

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Crash dumps may contain sensitive data (memory contents, credentials). Handle them securely.
Live debugging can affect the target process — use with caution on production systems.

Solução de problemas

Erros comuns e correções

WinDbg/CDB not found

Install Debugging Tools for Windows from the Windows SDK or WinDbg from Microsoft Store.

Verificar: where cdb

Symbols not loading

Configure symbol path: run_windbg_cmd with '.sympath SRV*c:\symbols*https://msdl.microsoft.com/download/symbols' then '.reload'

Verificar: Run 'lm' to check loaded modules

Dump file corrupted or incomplete

The dump may be a minidump missing key data. Request a full dump from the application or use procdump to capture a new one.

Verificar: Check dump file size — minidumps are typically <100MB

Alternativas

mcp-windbg vs. outros

Alternativa	Quando usar	Troca
cheatengine-mcp-bridge	You need live memory analysis of running processes rather than crash dump analysis	Live process manipulation vs post-mortem analysis
