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.

Token Reduction
HTML pages average ~12,000 input tokens. Our pipeline strips DOM boilerplate, deduplicates content, and compresses to structured Markdown — typically ~2,400 tokens delivered.
$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.
