Wire NHS into your agent — MCP server

Add Not Human Search as an MCP tool. Your agent can call search_agents, get_site_details, get_stats, and submit_site at runtime.

Claude Code
claude mcp add --transport http nothumansearch https://nothumansearch.ai/mcp
Other clients: point any MCP-compatible tool at https://nothumansearch.ai/mcp (streamable-http transport).

Use NHS via REST

Prefer plain HTTP? Hit the search endpoint directly.

Search API
curl "https://nothumansearch.ai/api/v1/search?q=payment+API"
