## What it does

The server exposes 111 Massdriver tools to an MCP client. An assistant can list projects, create an environment, start or roll back a deployment, pull logs, grant access to a resource, evaluate a policy. Transport is stdio by default, so any MCP client works; pass `-http` to serve Streamable HTTP instead.

You need a Massdriver API key and your organization ID before the first run. Both come from environment variables (`MASSDRIVER_API_KEY`, `MASSDRIVER_ORGANIZATION_ID`) or from a profile in `~/.config/massdriver/config.yaml`. Point `MASSDRIVER_URL` at your own instance if you self-host Massdriver.

The HTTP endpoint answers with `application/json` and carries no authentication, yet its tools mutate infrastructure. Bind it to localhost or put an authenticating proxy in front. In Docker, stdio needs an interactive stdin, hence the `-i` flag on the container.

## Requirements
- Needs: Docker
- Environment variables: `MASSDRIVER_API_KEY`, `MASSDRIVER_ORGANIZATION_ID`, `MASSDRIVER_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**

## When to use it
- list projects and environments in Massdriver
- trigger an environment deployment and read its logs
- compare two environments or two deployments
- create a policy and evaluate it against resources
- grant access to an OCI repo or a resource

## Example prompts
- List every environment in the project and flag the ones with unfulfilled dependencies
- Deploy to staging and pull the logs from the latest run
- Compare this environment with production and explain the differences
