Every capability carries its price in the tool table, so the cost of a run is knowable before it starts rather than discovered on an invoice. pylon_chain is the piece that makes it more than a menu: scrape a page, convert the result, host the file — planned and executed as one request instead of three round trips through the model.
A gateway to Pylon's capability catalog. Each capability is its own tool with its own per-call price, and three meta tools route a described task, chain several into a pipeline, or search for what is available.
- A task described in plain language and routed to whichever capability fits — pylon_do
- A multi-step pipeline planned and executed in order, with each step's output piped into the next — pylon_chain
- Capability search across both Pylon's own catalog and the x402 bazaar — pylon_discover
- Web work priced per call: screenshots and scraping at $0.01, web search at $0.003 — pylon_screenshot, pylon_web_scrape, pylon_search
- Documents in and out: PDF text extraction, OCR from images, and markdown or HTML converted to PDF — pylon_pdf_parse, pylon_ocr, pylon_md_to_pdf, pylon_html_to_pdf
- Network and identity checks: domain intelligence over WHOIS, DNS and SSL, DNS lookups, IP geolocation and email validation — pylon_domain_intel, pylon_dns_lookup, pylon_ip_geo, pylon_email_validate
- Small utilities that are otherwise a dependency each: QR codes, image resizing, URL shortening, JSON/CSV/XML/YAML conversion, document generation from templates, and file hosting
- Two resources the agent can read directly: the full capability list with schemas and pricing, and live service status with circuit-breaker states
No API key, no account and no subscription — npx -y @pylonapi/mcp, and calls are paid per request through x402 on Base. PYLON_GATEWAY_URL points at a self-hosted gateway instead of the default.
One command — npx -y @pylonapi/mcp
