Featured on

Doc Scraping

Fetch any library's documentation in seconds. We discover llms.txt, resolve registry metadata from npm/pypi/cargo/go, and extract clean Markdown — zero bloat, pure context.

Skill Repo

Curated agent skill packs served on demand. Your agent fuzzy-searches our skill library and loads the exact instructions it needs — frontend design, React best practices, and more.

Direct MCP

Five tools, one MCP server over HTTP — docs, skills, changelog digests, design-token scans, and OpenAPI fixtures. Connect Cursor, Windsurf, or Claude Desktop in seconds. Billing, rate limiting, and telemetry handled automatically.

MCP toolbox

Beyond docs and skills: ship-aware changelogs, front-end token snapshots, and API fixtures — same license, same compression ethos.

trim0_changelog_digest

Changelog digest

Point at any npm package and get recent versions with release notes — pulled from GitHub Releases when the registry links a repo. Ship upgrades with context, not guesswork.

trim0_design_tokens

Design token scan

Paste a public URL and we surface CSS variables, color stops, font stacks, and spacing hints from the page — a fast snapshot for matching or auditing a site’s look.

trim0_fixture_factory

Fixture factory

Feed an OpenAPI spec or JSON Schema and get example JSON payloads for requests — ideal for tests, mocks, and agent-driven API work without dumping the whole spec into context.

Pricing

The subscription is $0 per week — you only pay for metered usage. Polar bills usage weekly at $0.002 per request.

Base subscription

$0/week

Metered usage

$0.002/request

Each successful MCP tool invocation (docs, skills, changelog digest, design tokens, fixtures, etc.) counts as one request. Usage is totaled and charged weekly; no hidden tiers on the metered rate.

How it fits together

1.Sign up on Polar: $0/week subscription, then receive a license key tied to your account.
2.Add the key to your MCP client. Metered usage is $0.002 per request, charged weekly based on what you used.
3.Fair-use rate limits protect the service (10 requests per minute per key); your dashboard shows usage and savings.

Polar handles checkout and weekly billing for metered usage; invoices and usage breakdowns are in your Polar customer portal.

Start from the dashboard: connect MCP, paste your key — $0 weekly base, usage billed weekly.

$0.05

Saved Per Page (Opus 4.6)

At $5/M input tokens (frontier Opus-class pricing), 9,600 eliminated tokens save about $0.05 per request. Run 100 doc fetches a day and that's $5/day, ~$150/month — real money back in your pocket.
