A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

SYNTHORA x402 Intelligence Mesh — questions
Answers built from our own checks of this server.
What can SYNTHORA x402 Intelligence Mesh do?
It exposes 27 tools, read directly from the server on our last check. Among them: air_quality, bitcoin_fees, defi_llama_tvl_ranking, defi_yields, dnsdomain, doaj_article_search and 21 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 SYNTHORA x402 Intelligence Mesh mostly used for?
Its tools cluster around defi, polymarket and ecb. 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 SYNTHORA x402 Intelligence Mesh 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 266 ms. The bar chart above shows every period we have measured.
Did SYNTHORA x402 Intelligence Mesh ever remove tools?
Yes. address_risk_score, agent_pretrade_safety, dns_domain_intel, fda_drug_label and 126 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect SYNTHORA x402 Intelligence Mesh?
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 SYNTHORA x402 Intelligence Mesh need an API key?
No. SYNTHORA x402 Intelligence Mesh completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 27 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SYNTHORA x402 Intelligence Mesh?
It answers our handshake in 266 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
