Not every pwno-mcp tool returns data in exactly the same shape. This matters when you are wiring the server into an agent or building wrappers around it.

​
Main response families

Tool familyTypical shapeNotes
debugger and inspection toolsstructured objectusually includes success and session-specific fields
pwncli toolsstructured objectincludes session-aware I/O or event data
process, Python, repo, and RetDec helpersJSON-formatted stringparse the string if your client does not already coerce it
attach debugger tooltwo-part resultreturns the attach result plus a context snapshot list
attach sidecar APIstructured objectresponse model has successful, attach, and result

​
Structured object example

Debugger tools such as set_file, run, get_context, and set_breakpoint return objects directly. 
{
  "success": true,
  "session_id": "chal-a"
}
On failure they follow the common error envelope: 
{
  "success": false,
  "error": "Debug session 'chal-a' not found",
  "type": "RuntimeError"
}

​
JSON-string helper example

Automation helpers such as run_command, spawn_process, execute_python_code, fetch_repo, get_retdec_status, and get_decompiled_code return JSON strings. 
"{\n  \"success\": true,\n  \"returncode\": 0,\n  \"stdout\": \"...\"\n}"
If you are writing your own integration, do not assume every tool already returns a parsed object. Some helpers intentionally serialize their result with json.dumps(..., indent=2).

​
Attach-specific shapes

There are two attach surfaces:
  • the MCP attach tool returns an attach result plus a list of context snapshots
  • the HTTP /attach helper API returns a single object with this shape:
{
  "successful": true,
  "attach": {
    "success": true,
    "pid": 31337,
    "session_id": "chal-a"
  },
  "result": {
    "set-file": {
      "success": true
    }
  }
}

​
Practical advice

  • Treat debugger and pwncli tools as object-returning tools.
  • Treat process, Python, repo, and RetDec tools as string-returning helpers unless your client parses them for you.
  • When handling failures, always look for success, error, and type before assuming a result shape.
  • When handling attach flows, account for the extra context data or the attach-sidecar wrapper object.
