Nothing serious here today

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

Available tools 4

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

pubfi

pubfi.capabilities.get

Return the full typed request, response, metering, and readiness contract for one exact capability id from the installed Registry generation.

pubfi.capabilities.list

Enumerate the complete installed Registry v2 catalog as deterministic compact pages. The server does not rank, infer intent, or choose a capability.

pubfi.route.execute

Execute one exact GET or POST path through the authenticated PubFi account lane and the same Registry v2 matcher and typed executor as the HTTP gateway. Append :free only when the capability catalog publishes that exact account-scoped free variant.

pubfi.substrate.runtime_upgrade.verify

Verify one reviewed Substrate System.apply_authorized_upgrade extrinsic through the authenticated account lane. Supply the expected Blake2b-256 hash of the FRAME System AuthorizedUpgrade code payload, not the active :code hash at the apply block. The server streams and discards provider runtime code, persists only a compact proof, and returns independent comparison evidence.

PubFi MCP — questions

Answers built from our own checks of this server.

What can PubFi MCP do?

It exposes 4 tools, read directly from the server on our last check. Among them: pubfi.capabilities.get, pubfi.capabilities.list, pubfi.route.execute, pubfi.substrate.runtime_upgrade.verify. 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 PubFi MCP 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 483 ms. The bar chart above shows every period we have measured.

How do I connect PubFi MCP?

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 PubFi MCP need an API key?

No. PubFi MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is PubFi MCP?

It answers our handshake in 483 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is PubFi MCP open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
