Ministack Mcp

ministack-mcp

Your local AWS runtime. An MCP server that gives any AI agent (Claude, Cursor, Continue, Windsurf, Cline) a full AWS environment on localhost. The agent deploys your code, creates infrastructure, runs tests, and reports results — all locally, instantly, free.

You say "test my Lambda." The agent reads your code, deploys it, invokes it, and tells you if it works. You say "apply my Terraform." The agent runs it against the local environment and shows you what happened. You never think about MiniStack. You think about your code.

Install

pipx install ministack-mcp
# or
uvx ministack-mcp

What happens

The MCP tells your AI agent: "You have a local AWS environment. Use it."

• Developer: "Test my Lambda function" → agent deploys it locally, invokes it, reports pass/fail
• Tester: "Run my test suite" → agent spins up infrastructure, runs tests, cleans up
• SRE: "Apply my Terraform" → agent applies it locally, verifies resources, reports status

The agent uses 38 tools to act on your behalf. MiniStack runs 67 AWS services locally.

IDE configuration

Claude Desktop / Claude Code

{
  "mcpServers": {
    "ministack": {
      "command": "uvx",
      "args": ["ministack-mcp"]
    }
  }
}

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "ministack": {
      "command": "uvx",
      "args": ["ministack-mcp"]
    }
  }
}

Codex configuration

Codex uses the same local MCP contract as the other agents in this repo. Keep MINISTACK_ENDPOINT_URL pointed at the MiniStack instance you want to use.

Codex CLI

Register the server with the local uvx entry point:

{
  "mcpServers": {
    "ministack": {
      "command": "uvx",
      "args": ["ministack-mcp"]
    }
  }
}

If you need a non-default backend:

export MINISTACK_ENDPOINT_URL=http://localhost:4566
uvx ministack-mcp

Codex app

Use the same MCP server definition in the Codex app settings:

{
  "mcpServers": {
    "ministack": {
      "command": "uvx",
      "args": ["ministack-mcp"]
    }
  }
}

If the app exposes a separate MCP settings screen, add the same command and args pair there.

Continue / Windsurf / Cline

Same pattern — "command": "uvx", "args": ["ministack-mcp"] in your MCP config.

Set MINISTACK_ENDPOINT_URL if not using the default http://localhost:4566.
