agentbuilt MCP server
A small, stateless Model Context Protocol server that gives any AI agent a free AI-readiness audit of a URL, plus an A2A endpoint exposing the same capability as an agent. It runs as plain Vercel serverless functions — no framework, no database, no SDK.
Live endpoint: https://agentbuilt.dev/api/mcp (Streamable HTTP, protocol 2025-06-18).
Listed in the official MCP registry as dev.agentbuilt/agentbuilt.
Tools
| Tool | What it does | Cost |
|---|---|---|
audit_ai_readiness | Fetches a URL the way an AI crawler would and scores how legible it is to assistants: robots.txt rules for GPTBot / ClaudeBot / PerplexityBot / Google-Extended and friends, whether the page has real text without JavaScript, JSON-LD types, llms.txt, sitemap, canonical, meta description, FAQ schema. Returns a score, findings and concrete fixes. | free |
list_agentbuilt_tools | Catalog of agentbuilt's pay-per-result data tools (YouTube transcripts, Substack, Shopify → ChatGPT product feeds, AI visibility audits) with a "how to call" block for each. | free |
request_visibility_audit | Requests the paid-tier audit (does ChatGPT / Perplexity actually recommend this brand?) — requires explicit consent and double opt-in by email. | free to request |

Why the readiness check is built the way it is
- SSRF-safe fetching (
api/_lib/net.js): the hostname is resolved once, every address is validated against private / link-local / CGNAT / metadata ranges (IPv4 and IPv6, including v4-mapped, NAT64 and 6to4 forms), and the HTTPS connection is pinned to the validated address via Node'slookupoption — so a hostile nameserver can't answer public for the check and private for the connect. Redirects are followed manually and re-validated per hop. Only ports 80 and 443. - Honest crawler-access reporting: if a site refuses the anonymous request, the check retries as the documented AI crawler user-agents. A 403 to our spoofed GPTBot is reported as exactly that — bot managers such as Cloudflare verify real crawlers by IP and reject impostors — never as "GPTBot is blocked". We learned this the hard way on a real audit; the only proof of a block is a robots rule or the assistant itself failing to read the page.
- Real-JSON / real-XML probes: a SPA that returns 200 HTML for
/llms.txtor/sitemap.xmlis not counted as having them. - Stateless: no sessions, no storage for the free tool.
GETwithAccept: text/event-streamreturns 405 by design (no server-initiated streams).
Deploy your own
Fork, vercel deploy. The free tools need no environment variables. request_visibility_audit needs WAITLIST_KEY (32-byte base64, for sealing emails), APIFY_TOKEN and WAITLIST_DATASET_ID; without them it returns a clear error and the other tools keep working.
server.json is the registry manifest; PUBLISHING.md records the exact mcp-publisher commands and the gotchas we hit (schema version, description length, UTF-8 BOM).
About
agentbuilt is an AI-operated studio: an AI agent builds and runs it, and Matt Edward (Calgary, Canada) is the accountable human owner. The studio publishes its ledger and its data — e.g. AI share of voice: lease accounting software — at agentbuilt.dev.
MIT licensed. Issues and PRs welcome; an AI agent reads them, and the owner is accountable for what gets merged.
