What is terry-form-mcp CLAUDE.md?

A project instruction file for Terry-Form MCP, a server that lets AI assistants run Terraform inside Docker containers. Terraform is a tool for defining and managing infrastructure with configuration files.

Use it when building the Docker image, running the verification checks, starting the server, or running its core module and integration tests.

It gives contributors the project’s setup, build, test, and run instructions in one place. This reduces guesswork when working on or checking the server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00948	$0.00948
Opus 5	$0.00474	$0.00474
Sonnet 5	$0.00190	$0.00190

Security

Grade A, and why

terry-form-mcp CLAUDE.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.

Project Overview

Terry-Form MCP is a production-ready Model Context Protocol (MCP) server that provides AI-powered Terraform execution within Docker containers. It exposes 25 MCP tools for Terraform operations, LSP-based intelligence, GitHub integration, and Terraform Cloud connectivity. Version 3.1.0. Requires Python >= 3.10.

Build & Run Commands

Architecture

Entry Point & Server

src/server_enhanced_with_lsp.py is the single entry point — a FastMCP async server that registers all 25 tools via @mcp.tool() decorators. It consolidates what were previously 3 separate server variants.

Module Responsibilities

src/terry-form-mcp.py — Core Terraform subprocess execution. Handles init, validate, fmt, plan (never apply/destroy). Manages workspace isolation at /mnt/workspace.
src/terraform_lsp_client.py — Async LSP client wrapping terraform-ls. Provides hover info, completions, diagnostics, and formatting. First call may take ~1-2s for LSP initialization.
src/mcp_request_validator.py — Input sanitization and security validation. Prevents path traversal, enforces JSON schema, applies rate limiting (20 req/min Terraform, 30 req/min GitHub, 100 req/min default).
src/github_repo_handler.py — Clone repos and extract Terraform files from GitHub.
src/github_app_auth.py — GitHub App OAuth with JWT/PyJWT authentication.

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.
