minimal-godot-mcp: Instructions file for Codex

AGENTS.md

minimal-godot-mcp AGENTS.md is an instructions file for Codex, OpenCode from ryanmazzolini/minimal-godot-mcp. It costs 303 tokens per session, scanned A, original, MIT.

A service that exposes diagnostics from Godot's built-in language server to clients using the Model Context Protocol, a way for AI tools to call external tools. It also captures console output from Godot's debugging interface.

In plain words
What is it for?
Use it to check one GDScript file, scan all GDScript files, read or clear console output, and handle the connection to Godot's language server.
Why use it?
It lets coding agents inspect script errors and running-game output without directly changing the Godot project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

minimal-godot-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Agent Guidelines

Mission

Expose Godot LSP diagnostics to MCP clients for GDScript validation.

Scope

In Scope

  • Retrieve diagnostics from Godot's native LSP
  • Cache and format diagnostic data for MCP clients
  • Handle LSP connection lifecycle and reconnection
  • Capture console output from Godot DAP

Out of Scope

  • Project manipulation (nodes, scenes, resources)
  • Code generation or refactoring
  • Asset management
  • Debug session control (start/stop, breakpoints)

Constraints

  • Native LSP only - No custom Godot plugins
  • Minimal memory footprint - Cache only what's needed
  • Fast diagnostic response - Return cached data when possible
  • TypeScript strict mode - No any types
  • Few runtime dependencies - Keep the dependency tree small

MCP Tools

Tool Input Output
get_diagnostics { file_path: string } Diagnostics for single file
scan_workspace_diagnostics {} Diagnostics for all .gd files
get_console_output { limit?, category?, since? } Console output from running scene
clear_console_output {} Clear output buffer

See README.md#mcp-tools for response schemas.

Console tools require an active debug session (scene running in Godot).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
