Terry Form MCP Server

Terry-Form MCP is a containerized Model Context Protocol server that gives AI assistants like Claude safe, structured access to Terraform. It exposes 25 MCP tools spanning Terraform execution, LSP. Exposed over MCP by the terry form mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Its toolset

Everything the assistant can do here goes through one of these:

• Category — Tools
• Diagnostics — terry_lsp_debug, terry_workspace_info, terry_lsp_init, terry_file_check, terry_workspace_setup, terry_analyze
• Security — terry_security_scan, terry_recommendations
• GitHub — github_clone_repo, github_list_terraform_files, github_get_terraform_config, github_prepare_workspace
• Prerequisites — The Prerequisites tool exposed by this server
• Terraform — The Terraform tool exposed by this server

Configuration

You will need 8 environment variables: TERRY_HOST, TERRY_FORM_API_KEY, TERRY_CSRF_SECRET, TERRY_CONFIG_PATH, TERRY_TERRAFORM_LS_PATH, GITHUB_APP_ID, GITHUB_APP_PRIVATE_KEY_PATH, GITHUB_APP_PRIVATE_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Docker installed and running - Python >= 3.10 (for local development)

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the terry form mcp mcp server does with a few real requests.

When to reach for it

This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Terry Form MCP's toolset — Category, Diagnostics, Security and 3 more — is a fair guide to whether it matches your workflow. It is maintained by aj-geddes; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
