Install & configure

Prerequisites

required
Install uv
Install the uv Python package manager/runner, which is used to run the MCP server via uvx.
```
$ curl -LsSf https://astral.sh/uv/install.sh | sh
```
https://docs.astral.sh/uv/
required
Mint a Rachio access token
Run the token minting CLI once to generate a long-lived RACHIO_ACCESS_TOKEN for your Rachio account. The MCP server uses this token and does not read your Rachio password directly.
```
$ uvx --from rachio-mcp rachio-mcp-token
```

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `rachio-mcp` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install uv** — Install the uv Python package manager/runner, which is used to run the MCP server via uvx. Run: `curl -LsSf https://astral.sh/uv/install.sh | sh` (https://docs.astral.sh/uv/)
- **Mint a Rachio access token** — Run the token minting CLI once to generate a long-lived RACHIO_ACCESS_TOKEN for your Rachio account. The MCP server uses this token and does not read your Rachio password directly. Run: `uvx --from rachio-mcp rachio-mcp-token`

Canonical MCP server config (stdio transport):
- command: `uvx`
- args: ["rachio-mcp"]
- required environment variables:
  - `RACHIO_ACCESS_TOKEN`: Long-lived bearer token minted by rachio-mcp-token; required for authenticating to Rachio. (example: `<your-rachio-access-token>`)
- optional environment variables:
  - `LOG_LEVEL`: Python logging level. Defaults to INFO. Logs are written to stderr. (example: `<log-level>`)

Note: Use stdio transport only. Preferred install path is to run the server on demand with uvx; no separate install step is required. RACHIO_EMAIL and RACHIO_PASSWORD are only used by the one-time token-minting CLI and are not part of the MCP client config. If the token is later rejected, rerun rachio-mcp-token and update RACHIO_ACCESS_TOKEN.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
