Unified x64dbg MCP Server - 181+ tools merged from 5 implementations
35 tools with consistent naming (verb_noun pattern) and basic schemas, but critical gaps in parameter descriptions and output documentation. All tools have descriptions (10-50 chars, below 194-char baseline), but 60% lack parameter-level descriptions. No output schemas documented. Error handling absent. Schemas present but minimal, most parameters lack type constraints beyond basic string/number. No tool annotations (readOnlyHint, destructiveHint). Composition is reasonable (single responsibility per tool), but chaining support unclear due to missing output specs.
Analyze module for functions
Attach to running process by PID
Attach to process by name
Bypass NtQueryInformationProcess check
Bypass OutputDebugStringA trap
Bypass PEB.BeingDebugged check
Delete a breakpoint by address
No output schemas documented. LLMs cannot infer what fields to expect from tool responses, breaking downstream tool chaining and forcing wasteful discovery calls.
Descriptions are 40 - 60 characters (below 194-char baseline). Too terse to guide LLM selection. E.g., 'Pause execution' lacks context on when to use it vs. step_into/step_over.
Many parameters lack descriptions. E.g., 'condition' in set_breakpoint has a description, but 'size' in protect_memory lacks guidance on valid range or units.

No error handling guidance. Tools do not document what errors can occur, whether they are retryable, or what the LLM should do next (e.g., 'Address not found, try search_memory first').
No tool annotations (readOnlyHint, destructiveHint, idempotentHint). LLMs cannot distinguish safe read-only tools from destructive ones, risking accidental data loss.
