How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security80
Transport & Reachability100
Schema Quality & AI Usability86
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 4782 tokens (~62/item across 76 items; 69 tools + 7 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management95
  • Stability check failed: schema churn in the 29 days we've observed: 0 tool removals, 2 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage96
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 86% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "prepare_transfer" implies "transfer" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
  • An AI judge read all 71 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the NOT FOR HUMANS MCP server?

NOT FOR HUMANS is a hosted endpoint at https://mcp.notforhumans.fun/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 69 exposed · ~4,491 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the NOT FOR HUMANS MCP server?

NOT FOR HUMANS is an MCP server listed in the public MCP registry as io.github.notforhumansfun-rgb/not-for-humans. Public NFH knowledge, ownership epochs, versioned learning, Odd Jobs, and unsigned preparation. This page covers its hosted endpoint (https://mcp.notforhumans.fun/mcp).

Is the NOT FOR HUMANS MCP server safe to use?

NOT FOR HUMANS scores 87 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the NOT FOR HUMANS MCP server expose?

NOT FOR HUMANS exposes 69 tools: search, fetch, get_census_status, get_agent_wallet_onboarding, get_origin_stream, and 64 more. Their descriptions and schemas cost roughly 4,491 tokens of context every time the server is loaded.

Does the NOT FOR HUMANS MCP server require authentication?

No. We connected to NOT FOR HUMANS without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the NOT FOR HUMANS MCP server still maintained?

NOT FOR HUMANS is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
