AgentTools Hub does not always answer

Over the last week it answered 72.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

dev

dev_api_health_check

Probe a GET endpoint several times and report status codes and latency statistics (min/avg/max). The cheap way for an agent to verify an API — for example one found on the x402 Bazaar — responds before spending real money calling it. Use this when an agent needs to status and latency stats — test an API before relying on it. x402 price $0.005/call (USDC, eip155:8453).

dev_archive_lookup

Query the Internet Archive's Wayback index for any URL: when it was first archived, the most recent snapshot, how many years it spans, and recent capture dates.

Use this when an agent needs to exact line-level diff with unified-style output. x402 price $0.005/call (USDC, eip155:8453).

dev_directory_search

Describe what you need and get back matching x402-paid APIs: our own catalog (54 tools) plus, optionally, the live x402 Bazaar of third-party sellers. The agent's meta-tool — instead of knowing an API exists, ask for the capability. Use this when an agent needs to "I need a tool that does X" → matched paid APIs. x402 price $0.003/call (USDC, eip155:8453).

dev_domain_availability

Check whether a domain name is registered or available, via the official RDAP registry protocol (404 = available).

AgentTools Hub — questions

Answers built from our own checks of this server.

What can AgentTools Hub do?

It exposes 77 tools, read directly from the server on our last check. Among them: calculators_age_calculator, calculators_bmi_calculator, calculators_compound_interest_calculator, calculators_date_difference_calculator, calculators_discount_calculator, calculators_fuel_cost_calculator and 71 more. 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 →

What is AgentTools Hub mostly used for?

Its tools cluster around dev, calculators and converters. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is AgentTools Hub working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 97 of 116 checks got a reply (83.6%), average response time 354 ms. The bar chart above shows every period we have measured.

Is AgentTools Hub still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect AgentTools Hub?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AgentTools Hub need an API key?

No. AgentTools Hub completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 77 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AgentTools Hub?

It answers our handshake in 354 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
