Available tools 6

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

outcome
outcome_quote
Free quote for a verifiable HumanMirror Outcome contract. Describe the objective or provide an outcome_type; the quote returns the deterministic verifier, selected internal tool and success-only credit cost.
outcome_run
Execute a HumanMirror Outcome contract. Credits are charged only when deterministic verification succeeds; failed execution or failed verification is automatically refunded.
outcome_verify
Free deterministic re-verification of an Outcome result without consuming Nexus credits.
nexus
nexus_call
Route a tool call through HumanMirror Nexus. Use nexus_search first, then call the selected tool_id. Successful calls consume the number of Nexus credits declared by the selected tool.
nexus_search
Search the HumanMirror Nexus catalog for a machine-callable tool that matches a task. This search is free and does not consume credits.
magnet
magnet_resolve
Free universal fallback discovery. Call this when the agent cannot satisfy a task with its current capabilities. Magnet returns a matching HumanMirror tool or records an aggregated capability gap in the Machine Demand Graph. This tool consumes no credits.

HumanMirror Nexus — questions

Answers built from our own checks of this server.

What can HumanMirror Nexus do?
It exposes 6 tools, read directly from the server on our last check. Among them: magnet_resolve, nexus_call, nexus_search, outcome_quote, outcome_run, outcome_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 →
What is HumanMirror Nexus mostly used for?
Its tools cluster around outcome and nexus. 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 HumanMirror Nexus 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 258 ms. The bar chart above shows every period we have measured.
Is HumanMirror Nexus 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 HumanMirror Nexus?
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 HumanMirror Nexus need an API key?
No. HumanMirror Nexus completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is HumanMirror Nexus?
It answers our handshake in 258 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
