Available tools 7

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

chat

embed
embed
Compute embeddings on the Phase AI gateway (paid from the Phase API key or the wallet).
key
key
Balance, daily cap and spend of the Phase API key this server pays with (key mode).
models
list_models
List models of the Phase AI gateway with prices (USD per 1M tokens, fee per call) and layer (flagship | open | class | free).
quote

Get the price ceiling for a chat request without paying (the gateway's 402 quote).
receipt
receipt
Fetch the public receipt of a paid request by task id (model, provider, tokens, price, settlement tx, request/response hashes, signatures) and its Merkle proof once the weekly epoch is closed.
session
session
Saved chat sessions on the Phase AI gateway: create one (returns an id and a shareable /s/<id> link), read its thread, list the wallet's sessions (wallet mode only: signed with the wallet key, no transaction), or delete one. Pass the id as `session` to chat and the gateway carries the context between turns and visits.

PHASE MIND — questions

Answers built from our own checks of this server.

What can PHASE MIND do?
It exposes 7 tools, read directly from the server on our last check. Among them: chat, embed, key, list_models, quote, receipt and 1 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 →
Is PHASE MIND working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 445 ms. The bar chart above shows every period we have measured.
Did PHASE MIND ever remove tools?
Yes. compare, docs, route_explain, usage 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 PHASE MIND?
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 PHASE MIND need an API key?
No. PHASE MIND completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is PHASE MIND?
It answers our handshake in 445 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
