Citra
Give your AI agent eyes for PDFs — with proof.
Local-first PDF evidence for agents. Structured text, tables, OCR, visual crops, and page-level citations your agent can defend — not invent.
Canonical package @sylphx/citra · bin citra · MCP io.github.SylphxAI/citra · live 5.0.0
Zero-config in one line
npx -y @sylphx/citraNo Docker. No API key. No global install. Spawns a stdio MCP server agents can use immediately.
Why Citra feels unfairly good
Plain-text PDF tools make agents guess. Citra returns an Agent Document Twin they can cite.
Five reasons teams pick Citra
- Zero-config — real npx MCP, not a 20-step bootstrap.
- Evidence, not vibes — citations agents can show a human.
- Local-first — PDFs stay on the machine; no required cloud vision API.
- Brand-sole — one package, one bin, one story (@sylphx/citra / citra).
- Instrument family — compose with Iris (image), Cue (video), Spine, Lookout, Locus.
See the difference
What you get
Three tools. One product surface.
Minimal call:
{
"sources": [{ "path": "/absolute/path/to/report.pdf" }]
}Flagship use cases
- Financial reports — extract table cells agents can cite by page and geometry
- Research papers — headings, reading order, page-level quotes
- Scanned documents — OCR path with evidence, not a text soup
Platforms
One optional native package is selected for your host only:
Missing native → fail closed (no silent TypeScript PDF engine).
Product docs
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y @sylphx/citra on your machine. Read the scan report first; the gateway never runs local packages.
