# Sign in with JustClaw-It: add licence-cleared components to Claude.ai and ChatGPT

*2026-11-02 · JustClaw-It*


Until now, JustClaw-It worked best in coding agents that read an MCP config file: Claude Code, Cursor, Codex and the rest, with an API key in a header. Claude.ai and ChatGPT don't have a config file. They add remote MCP servers as **connectors**, and a connector signs in with OAuth rather than a pasted key.

JustClaw-It now supports that. Add `https://justclaw.it.com/mcp/signin` as a connector, sign in with your JustClaw-It account, approve the app, and the chat can search 4,519,159 licence-cleared components and pull the source with its licence and attribution.

## What you get in the chat

The connector has the same tools as any other JustClaw-It client, on your own account:

- **Search is free.** `search_components`, `find_similar` and the other discovery tools cost 0 credits.
- **A pull costs 1 credit.** `get_component` returns the full source with a GitHub permalink, the SPDX licence, the copyright holder and an attribution header to keep with the code.
- **Security checks are free.** `check_component_security` lists published advisories for a component or its repository, with OSV severity and fixed versions where they are known ([Security advisories](/docs/security-advisories)).
- **Your plan comes with you.** The connector spends your account's credits: on Free, up to 300 pulls a month (10 a day) plus 30 on signup. Pro adds `get_component_bundle` and `compose_starter` ([Credits & plans](/docs/credits)).

Every component in the public library comes from a repository whose licence is permissive or weak-copyleft ([How licensing works](/docs/how-licensing-works)). The licence still travels with the code: keep the attribution header when you use it.

## Add it to Claude.ai

1. In Claude, open **Settings → Connectors** and choose **Add custom connector**. On a Team or Enterprise plan, an owner adds it in the organisation settings first.
2. Name it `JustClaw-It` and set the remote MCP server URL to `https://justclaw.it.com/mcp/signin`.
3. Choose **Add**, then **Connect**. A JustClaw-It window opens.
4. Sign in. If you're already signed in at justclaw.it.com in that browser, you go straight to the consent screen. Otherwise enter your email and open the one-time sign-in link in the same browser; a new address gets a free account.
5. Check the consent screen. It shows the app, where it sends you back to, your email and your plan. Choose **Approve**.

The connector then shows as connected. In a new chat, make sure its tools are switched on in the tools menu. Full steps: [Claude.ai](/docs/clients/claude-ai).

## Add it to ChatGPT

Custom MCP connectors in ChatGPT need **developer mode**, which OpenAI offers on some plans and workspaces only.

1. Open **Settings → Apps & Connectors → Advanced settings** and turn on **Developer mode**.
2. In **Apps & Connectors**, choose **Create** and fill in: name `JustClaw-It`, MCP Server URL `https://justclaw.it.com/mcp/signin`, authentication **OAuth**.
3. Confirm that you trust the connector and choose **Create**. The JustClaw-It sign-in window opens.
4. Sign in and approve on the consent screen, as above.

In a chat, pick the JustClaw-It connector from the tools menu. Full steps: [ChatGPT](/docs/clients/chatgpt).

## Try it

> Use JustClaw-It to find a licence-cleared React date picker and show me its licence before pulling it.

> Search JustClaw-It for a Stripe webhook handler with retries, check it for security advisories, then pull the best one.

A good pattern is to let the model search and compare first (free), and only pull the one you want (1 credit).

## What the connector can't do

The app you approve can search, check and pull components on your account. It can't see your billing, change your account or create API keys. To stop it, open [your account](/account#apps) → **Connected apps** → **Disconnect**: it is signed out at once. You can also remove the connector in Claude's or ChatGPT's settings.

## No account yet?

`https://justclaw.it.com/mcp` (without `/signin`) still answers `search_components` with no key or sign-in, with a small per-network limit, so you can try a search first. Coding agents with a config file keep using an API key: see the [quickstart](/docs/quickstart).
