mcp setup

Connect JustClaw-It to your agent.

quality signals

Know why a result ranks.

Every component carries five 0–10 sub-scores, averaged into one composite. Your agent sees all of them, and can pass min_composite to skip anything below the bar.

Browse 7+ UI components →
CompletenesscompletenessDoes it handle the edges you need to actually use it?
Code qualitycode_qualityIs it readable, structured and maintainable?
DeployabilitydeployabilityHow close is it to running in a real project?
ReusabilityreusabilityCan an agent adapt it without rewriting the feature?
Strategic valuestrategic_valueIs it the kind of building block worth reusing at all?

Scores come from an automated grader: static signals (repository health, licence, tests, size and structure) for every public component, with a model-graded review replacing the static score as it rolls out across the library — today 43% of scored components (2,086,146 of 4,817,681) have a model-graded review; the rest carry the static score. Treat the composite as a starting signal, not a verdict.

why JustClaw-It

Why it's worth connecting

licence-cleared, with attribution

Only permissive and weak-copyleft code is served. Every result carries its SPDX licence, copyright holder and repository, and returned source starts with an attribution header — so what your agent ships is clean.

real production provenance

Every component is mined from an actual public repo, not generated on the fly — you get code that already works somewhere, with a GitHub permalink back to its source.

scored, not guesswork

Each component carries 5 sub-scores (completeness, code quality, deployability, reusability, strategic value) rolled into one composite — filter by min_composite and skip the weak ones. Today 43% of scored components (2,086,146 of 4,817,681) have a model-graded review; the rest carry a static baseline score.

scale a hand-curated kit can't match

4,670,722 real components with full source, pulled from thousands of real codebases rather than one.
vs. docs servers

Context7 tells your agent how a library works; JustClaw-It hands it production code that uses it.

Use both: docs for the API surface, JustClaw-It for a working, scored, licence-cleared implementation your agent can drop in with attribution intact.

common questions

A clear path from search to source.

Does JustClaw-It generate code?

No. It finds existing, licence-cleared implementations mined from real public repositories and hands your agent the source. Your agent decides how to adapt it to your project.

Can I use what it returns in a commercial product?

The public library only serves permissive and weak-copyleft code (for example MIT, Apache-2.0, BSD, MPL-2.0). Each component's own licence governs: keep the attribution header it comes with.

Can I inspect a component before my agent uses it?

Yes. Every result links to its page with the repository, path, licence, scores and a source preview; try the browser.

Which clients can connect?

Any MCP client that speaks streamable HTTP with a bearer header: Claude Code, Cursor, VS Code, Codex, OpenClaw, Hermes, Windsurf and Claude Desktop each have copy-paste steps in client setup. Claude.ai and ChatGPT connect through "Sign in with JustClaw-It" (OAuth, no key to paste): see the Claude.ai and ChatGPT pages.

Where does my API key go?

Only into your agent's MCP config, as an Authorization header. It is never needed on this website, and you can rotate it any time from your account.

How do the quality scores work?

Five 0–10 sub-scores averaged into a composite; see quality signals above.

What does it cost?

Searching is free on every plan (with fair-use limits). Credits pay for pulling a component's source: the free tier gives 30 to start and 10 a day after that, no card. Paid plans add weekly credits that carry over; see pricing.

How is this different from Context7?

Context7 tells your agent how a library works; JustClaw-It hands it production code that uses it. Use both.

Free search on every plan (keyless search is capped per network). Free tier: up to 300 free component pulls a month (10 a day) + 30 on signup; daily credits don't carry over. A JustClaw-It pull returns a complete, licence-cleared component (full source, licence, attribution header and GitHub permalink), not a snippet of documentation. No credit card.
