Agent Tools — x402 MCP Directory

Rank #106,884

smithery/kangletian/agent-tools-x402-directory

Free, agent-first MCP discovery layer for the **x402 paid-service ecosystem**. Aggregates **2,000+ x402 / MCP services** crawled from awesome-x402, x402scan, x402.org/ecosystem and cdp-bazaar, refreshed every 6 hours. Built so an autonomous agent can go from *"I need to fetch tweets / check whale flows / get a price"* to a **paid, callable endpoint in seconds** — no human in the loop. ## Why it's different - **Quality-scored ranking, not keyword soup.** Every result carries an x402scan **`confidence`** score (0–1) and **`tx_30d`** (30-day real on-chain payment count). Results are ordered *healthy + real-traffic first*, with a human-readable **`match_reason`** so the agent knows *why* each service was picked. - **LLM-powered recommendation.** `ask_services` retrieves candidates, then has a backend LLM rank *only* those candidates and return ready-to-use service cards — gracefully falling back to the deterministic ranker if the LLM is unavailable. - **Inspect before you pay.** `get` returns a full service card with the exact endpoint, price, network, MCP URL, health, and a ready-to-paste MCP / HTTP-402 call template. ## Tools - `ask_services(intent, …)` — LLM-ranked "just give me the best service for this job" recommendation. - `search(intent | filters, …)` — quality-ranked discovery (FTS5 + popularity + health), returns `confidence`, `tx_30d`, `match_reason`, `mcp_url`. - `get(slug)` — full service card + ready-to-paste call template. - `list_categories()` — browse the taxonomy. - `stats()` — live directory size & health snapshot. - `register(url, …)` — self-register a new x402 / MCP service (free, human-reviewed). ## Free No API key, no usage fees. Backed by [agent-tools.cloud](https://agent-tools.cloud) and the Apache-2.0 PyPI package [`agent-tools-mcp`](https://github.com/JoursBleu/agent-tools-mcp).
