# AgentPass

> AgentPass scores how easily AI agents can read, trust and operate a website: a 100-point ARI-100 score, a letter grade, a per-crawler reachability matrix and a paste-ready fix pack. Free scan, JSON and Markdown reports, MCP tools.

When to use this site: call the API when you need a deterministic agent-readiness score for a URL, or fetch a cached report for a host that was already scanned. Use the MCP endpoint when an agent is doing the work and wants the scan as a tool call.

## Scan API

- [Scan a URL](https://agentpass.page/api/scan?url=https://example.com) — the primary call: GET, returns the full ARI-100 report as JSON
- [OpenAPI 3.1 description](https://agentpass.page/openapi.json) — every path, parameter and schema, with descriptions
- [API reference](https://agentpass.page/api) — prose docs, curl examples, error shape
- [Most recent scan](https://agentpass.page/last) — a small summary of the last report in this process

## MCP endpoint

- [MCP server](https://agentpass.page/mcp) — JSON-RPC 2.0 over POST; tools: scan_site (input {url}) and get_report (input {host})
- [MCP server card](https://agentpass.page/.well-known/mcp.json) — name, transport, url, auth and tool schemas

## Reports

- [Report JSON](https://agentpass.page/report/example.com.json) — cached report for a host, 6-hour TTL
- [Report Markdown](https://agentpass.page/report/example.com.md) — the same report as text/markdown
- [Badge](https://agentpass.page/badge/example.com.svg) — SVG score badge for a scanned host
