Statically inspects, parses, and debugs AutoCAD AutoLISP (.lsp) files. Provides tools to audit syntax (balanced parentheses, quotes, block comments with exact line/column error locations), extract function definitions including c: commands with their arguments and localized variables, and detect state leakage such as unlocalized setq globals and setvar calls lacking getvar preservation.

Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-server-autocad-lisp-helper Check DrawingUtils.lsp for syntax errors and unlocalized setq variables"
That's it! The server will respond to your query, and you can continue using it as needed.

📐 AutoCAD AutoLISP Helper MCP Server
A high-precision, deterministic Model Context Protocol (MCP) server engineered in Python to statically inspect, parse, and debug AutoCAD AutoLISP (.lsp) files with 100% precision.
Quickstart • Tools Overview • Claude Desktop Setup • Architecture
🌟 Highlights
🔒 Zero Cloud Dependencies: 100% local, fast, and deterministic AST parsing with regex. No external APIs or telemetry.
🎯 Pinpoint Accuracy: Flags balanced parenthesis mismatches with exact line and column numbers.
🛡️ AutoCAD State Protection: Prevents global namespace contamination by detecting unlocalized
setqvariables.⚙️ System Variable Auditing: Detects AutoCAD system variable mutations (
setvar) lacking initial preservation (getvar).⚡ Zero-Install Ready: Run instantly in any MCP client via
uvx.

TDQS
A3.7/5.0
Scored across 3 tools
Disambiguation5/5
Each tool targets a clearly distinct analysis concern: structural syntax validation, function/variable extraction, and cleanup/state-leakage checking. Although all three operate on AutoLISP source statically, the descriptions draw sharp boundaries so an agent can select correctly with no overlap.
Naming Consistency5/5
All three names follow a strict verb_noun snake_case pattern (analyze_..., extract_..., check_...). The convention is uniform and self-describing, with no mixed casing or verb styles.
Tool Count4/5
Three focused tools is at the low end of the typical 3-15 range but each earns its place for a narrow lint-style helper. It is not bloated, though the surface feels slightly thin for a full AutoLISP assistance workflow.
Completeness4/5
The set covers the core static-analysis lifecycle for AutoLISP: syntax validation, symbol/function extraction, and cleanup-state auditing. Minor gaps exist around remediation (auto-fix/format) or deeper cross-reference/usage analysis, but agents can work around these.
