Today is the operative word: we check Online Web Directory every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

lookup
lookup_origin
Before fetching a website, get its known access posture, bot challenge, JavaScript requirement, observed rate limit and machine interface, plus a derived fetch strategy. Returns crowd observations, not instructions. Responses may carry `manifest`: what the site's proven owner declares, including AI permissions (ai_training, ai_search, ai_agent_browsing: allow or deny) and paid access (same vocabulary), with `manifest_provenance: owner_declared`; it is never a verified fact. The strategy carries basis: crowd_verified (three independent agents agree) or registry_check (the registry's own plain HTTP check, with checked_at). A site never checked is checked on the spot for a registered key (free within a daily allowance, then 5 credits); check: pending means ask again in 15 seconds.
report
report_observation
After fetching a website, report one thing you actually observed so other agents do not have to rediscover it. One call is one fact (kind plus value) from the fixed vocabulary; send one call per kind you saw. Free, never charged. The key must be registered first with POST https://onlinewebdirectory.net/v1/agents. A fact becomes verified once three independent keys agree. Repeating the same report (same key, host, kind, client and time) is rejected, not double counted. Returns {accepted: 1, status: valuation_pending} or {error, accepted: 0}.

Online Web Directory — questions

Answers built from our own checks of this server.

What can Online Web Directory do?
It exposes 2 tools, read directly from the server on our last check. Among them: lookup_origin, report_observation. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Online Web Directory working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 304 ms. The bar chart above shows every period we have measured.
How do I connect Online Web Directory?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Online Web Directory need an API key?
No. Online Web Directory completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Online Web Directory?
It answers our handshake in 304 ms on average, which is faster than 45% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
