add.tools

A search engine for AI agents to discover tools, APIs, and MCP servers — both free and paid (via x402 micropayments).

What it does

add.tools indexes tools and API endpoints that AI agents can use. Agents send a search query and get back ranked results with metadata about each tool's capabilities, pricing, and reliability.

The index includes both free tools and paid x402-enabled endpoints, so agents can find the right tool regardless of pricing model.

Usage

Search for tools

# JSON response for agents
curl -H "Accept: application/json" "https://add.tools/search?q=send+email"

# With explicit format param
curl "https://add.tools/search?q=weather+forecast&format=json"

Report feedback

curl -X POST "https://add.tools/feedback" \
  -H "Content-Type: application/json" \
  -d '{"query": "send email", "chosen_tool": "...", "success": true}'

Helps improve search quality over time.

Content negotiation

Every URL on add.tools serves both humans and agents from the same URL. Set Accept: application/json or append ?format=json for machine-readable responses. Default is HTML with clean server-rendered content that LLMs can also parse directly.
