Install

How do I install the nohumans.directory MCP server?

nohumans.directory is a hosted endpoint at https://api.nohumans.directory/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 · 4 exposed · ~720 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 →

Tool Tokens
find_paid_service ~296

Search paid x402 APIs and datasets by need. Ranked: verified first, then probe score, then price. Each result carries what you choose on: status, score (0..1), evidence_tier, paid_verified (we bought it with real USDC and it delivered), has_sample (a cheap preview exists), price. Relevance comes from the query text; a specific need in plain words matches best. Zero results means nothing listed matches. Results are dated evidence, not guarantees. Returns a summary per listing; detail='full' returns every field. Free, read-only.

NameTypeReqDescription
categorystring–Optional filter: one of the most-populated categories. Omit if none fits; query text still finds long-tail ones.
detailstring–summary (default) or full: every field per listing.
limitinteger–Max results (default 10).
max_pricenumber–Max price per call. Omit for no cap.
min_scorenumber–Min probe score, 0..1 (0.8 = reliably passing).
mpp_methodstring–Only listings offering this MPP method, e.g. stripe, tempo, evm.
protocolstring–Only listings offering this payment protocol. Omit for any.
querystring–What you need, specifically: data, freshness, format, constraint. Drives relevance.

get_service_details ~136

Full record for one listing id: request and response schemas, sample_query, observed 402 terms (network, payTo, scheme, x402 version), reputation detail, and paid_verification (our latest real USDC purchase, with its settlement tx where proven). Useful before paying: it shows the exact request shape and current reliability. Every timestamp has an _iso twin; on-chain counts describe the seller's wallet, usually shared by several listings, not this endpoint. Free, read-only.

resolve_endpoint ~94

Check an endpoint URL you already hold before paying it. Returns match 'active' with the listing's full record, 'delisted' (listed here, later removed), or 'unknown' (never checked here; absence is not a verdict either way). The record is dated evidence, not a safety rating. Free, read-only.

what_agents_are_asking_for ~194

What agents searched this directory for, for deciding which x402 service to build or list. Terms ranked by how many distinct days they were asked, each with catalogue_top: the listings our own search already returns for it. A term being asked does not mean nothing serves it. The window ends a week behind live while the paid tier is on sale (a day when it is not; delay_hours and window_ends_at in the response say which); test traffic, sellers searching their own listings and identifying terms are excluded; floor: a term appears once at least 1 distinct non-seller client IP asked it. Client counts are IP ceilings, never buyer counts. Paged: limit (default 25), offset, next_offset. Free, read-only.

Common questions

What is the nohumans.directory MCP server?

nohumans.directory is an MCP server listed in the public MCP registry as directory.nohumans/registry. We buy from x402 endpoints with real USDC and publish delivery outcomes. Check before you spend. This page covers its hosted endpoint (https://api.nohumans.directory/mcp).

Is the nohumans.directory MCP server safe to use?

nohumans.directory scores 84 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 nohumans.directory MCP server expose?

nohumans.directory exposes 4 tools: find_paid_service, get_service_details, resolve_endpoint, what_agents_are_asking_for. Their descriptions and schemas cost roughly 720 tokens of context every time the server is loaded.

Does the nohumans.directory MCP server require authentication?

No. We connected to nohumans.directory without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the nohumans.directory MCP server still maintained?

nohumans.directory is still listed as active in the MCP registry. We last reached this channel on 14 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
