# Ownhand

Agents, writing like you.

Ownhand is a remote MCP server that writes text in your own voice, fitted to where it is going: a Slack DM, a cold email, a PR description. It learns your voice from 5 to 10 things you wrote, then keeps learning from what you actually send.

- Endpoint: `https://ownhand.dev/mcp` (streamable HTTP)
- Sign-in: OAuth 2.1 with dynamic client registration. Add the URL, sign in in the browser, pick your Hand, click Allow. No API key to copy.
- New accounts start with $1 of free credit.

## Set up with one sentence

Paste this into any agent (Claude Code, Codex, Cursor, Gemini CLI, and others). It adds the server, starts sign-in and sets up your Hand.

```text
Fetch and execute the instructions to set me up for Ownhand from https://ownhand.dev/agent-setup/prompt.md. If your web tool can't open it, download it with curl or Invoke-WebRequest.
```

```

More configs, including VS Code (`.vscode/mcp.json`) and Codex (`config.toml`), are in [`examples/`](examples/). The live version of this table is at https://ownhand.dev/connect.

### Scripts and CI

For clients without browser sign-in, an API key option is described in the docs: https://ownhand.dev/docs#connect

## First run

Once connected, say: **"Set up my Ownhand Hand."** The agent asks for 5 to 10 things you wrote yourself (Slack messages, emails, PR descriptions) and how you'd describe your writing, then calls `create_hand`. Clients that show MCP prompts also list `set_up_my_hand`.

To make your agent use Ownhand without being asked, paste [`AGENTS.md`](AGENTS.md) into your `CLAUDE.md`, `AGENTS.md`, `.cursorrules` or custom instructions.

## Tools

| Tool | What it does |
|---|---|
| `write` | Rewrites a draft so it reads like you wrote it, fitted to the occasion. Keeps every fact. Returns the text and a `request_id`. |
| `send_feedback` | Reports what you did with a draft (`approved`, `edited` with the exact sent text, or `rejected`) so your Hand learns. |
| `get_hand` | Lists your Hands, or shows what one has learned: style card, rules, sample counts. |
| `create_hand` | Creates a Hand from texts you wrote yourself. |
| `update_hand` | Adds samples, sets how you describe your writing, or pins, rejects or activates a learned rule. |
| `get_account` | Shows your account, credit balance, recent charges and usage. |

Prompts: `set_up_my_hand`, `teach_my_voice`, `reply_to_thread`, `draft_email`.
Resources: `ownhand://guide` (the agent playbook), `ownhand://occasions` (the occasion table).

Occasions: `chat_dm`, `chat_channel`, `email_internal`, `email_formal`, `email_cold`, `email_warm`, `proposal_cold`, `proposal_warm`, `pr_description`, `review_comment`, `docs`, `status_update`.

## How learning works

1. Your agent calls `write` and shows you the draft. Nothing is sent without your OK.
2. You send it as is, edit it, or drop it.
3. Your agent calls `send_feedback` with exactly the text you sent.
4. Ownhand compares the draft with what you sent and updates your Hand. A reason you state becomes a rule right away. A pattern it only observes has to show up twice. Learning runs in the background, and the Hand's version goes up when it finishes.

You can pin or reject any learned rule with `update_hand`. Learning from your feedback changes only your own Hand.

## Pricing

$1 free to start. Then you add credit and pay for the tokens you use, about half a cent per rewrite. No subscription and no monthly fee. Details: https://ownhand.dev/pricing.

## Privacy

- Stored: your account details, your Hands (samples, style card, learned rules), your requests and the feedback you send.
- Not stored: thread messages your agent passes as context. They are used for that one request.
- Not sold, not shared for advertising, and not used to train our own models.
- Writing and learning run on Muse Spark through OpenRouter's contributor tier, so the provider may use everything Ownhand processes (drafts, samples, thread context, feedback) to improve its models. Don't use Ownhand for text you want kept out of that.
- You can delete a Hand or revoke a key at any time.
