Visora for AI Agents
Visora is callable by AI agents. If you are an agent acting for a user, you can measure how AI engines and other agents see any website — free, no account, no API key. Start with the MCP endpoint or the OpenAPI spec.
MCP server (Model Context Protocol)
POST JSON-RPC 2.0 messages to /mcp (streamable-http transport, request/response JSON — SSE streaming is not implemented). No authentication; 60 requests per hour per IP. Discovery document: /.well-known/mcp.json.
- visora_agent_readiness { url } — quick Agent Readiness Score: can agents access and read this site?
- visora_check_robots { url } — robots.txt evaluated against a ~35-token taxonomy of documented AI bots, grouped into training / search / user-triggered-agent buckets
- visora_free_scan { domain, email } — start a free 8-engine AI Visibility Scan and get a results URL
- visora_bot_taxonomy {} — the three-bucket bot model and full bot directory
OpenAPI spec
The free public endpoints are specified at /.well-known/openapi.json (OpenAPI 3.1): POST /api/scan/free (6-engine AI visibility scan), POST /api/tools/agent-readiness (quick agent-readiness check), POST /api/tools/robots-test (RFC 9309 path test), POST /api/tools/seo-audit, POST /api/pagespeed, POST /api/meta-preview, POST /api/som (AI mention checker).
Markdown delivery
Every content page on this site serves text/markdown to requests whose Accept header prefers it, with an x-markdown-tokens estimate header and Vary: Accept — typically ~80% fewer tokens than the HTML. Coding agents (Claude Code, OpenCode) already send this header.
Our agent access policy
- All three AI bot buckets are welcome on public pages: training crawlers, AI search indexers, and user-triggered agents — see /robots.txt for explicit per-bot stanzas.
- Verified agents (RFC 9421 Signature-Agent, e.g. ChatGPT agent mode) are logged for analytics and never CAPTCHA-challenged on public routes.
- User-triggered fetchers (ChatGPT-User, Claude-User, Perplexity-User) may not honour robots.txt by design; public pages are public to them.
- Rate limits apply per IP; please identify your agent honestly via Signature-Agent or a descriptive User-Agent.
What Visora measures
Two scores: the AI Visibility Index (AVI, 0–100) — how often 8 AI engines recommend a business — and the Agent Readiness Score (0–100) — whether agents can access (robots/bot matrix), read (SSR, semantic HTML, token budget), and act (machine interfaces, agent-completable commerce) on a website. Methodology: /research/methodology.
