For AI agents and copilots

ToolHund helps AI agents choose the right AI service for any task.

One decision endpoint. One MCP tool. One licensed data feed. Built for apps, agents, copilots and workflows that need to pick an AI tool at runtime — not read a listicle.

What agents get

Recommend API

POST /api/v1/recommend — natural-language task → 1–3 ranked AI tools with reasoning, pricing and tradeoffs. Deterministic, no LLM in the ranking path.

See endpoint

MCP tool: recommend_ai_tool

Drop the Recommend Engine straight into Claude Desktop, Cursor or any MCP-compatible agent. One tool call, ranked picks with monetization disclosure.

OpenAPI spec

Machine-readable OpenAPI 3.1 for the whole API — recommend, categories, tools, compare, deals, news. Wire it into any codegen or agent framework.

llms.txt

A curated llms.txt so LLM crawlers discover the endpoints and MCP entrypoints without scraping HTML.

See llms.txt

Structured AI tool data

Pricing, categories, alternatives, scores and freshness metadata — normalized fields, not scraped HTML. Available via API or a licensed data feed.

License the data

Attribution & disclosure

Every recommendation carries a monetization block: has_affiliate_link, is_sponsored (always false in ranking), and a plain-English disclosure. Ship it in your UI.

Read methodology

Use cases
