# OnchainAI

> Crypto tool directory for humans and AI agents. Discover, vet, and install MCP servers, CLIs, SDKs, APIs, x402 services, and AI-agent tools across chains — with trust scores, install-risk gating, and x402 payment disclosure.

For AI agents: connect to the free, read-only MCP endpoint `https://www.onchain-ai.xyz/mcp` (streamable HTTP, JSON-RPC over POST, no auth). Tools: search_tools, get_tool_detail, get_install_guide, list_categories, get_dashboard_snapshot. Never install tools whose install_risk_level is "critical"; always disclose x402 pricing before a paid tool is called. Claude Code users can install the plugin: `/plugin marketplace add Coinyak/onchainai` then `/plugin install onchainai@onchainai`.

- x402: OnchainAI publishes payment metadata and verification flags only — it never holds funds, proxies payments, or acts as a facilitator.
