agent-tools (x402 + MCP + A2A directory) is an MCP server with 11 tools an agent can call, among them ask_services, get, get_mcp_server. It answers at https://agent-tools.cloud/mcp-discovery/ over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Discover x402 services, MCP servers and A2A agents by intent — agent-tools.cloud directory.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
ask_services | Ask for the best x402/MCP services for an agent intent. This is the high-level discovery tool: it retrieves candidates from the directory, asks the configured backend LLM to rank only those candidates, and returns service cards for the sele Inputs: intent, top_k, max_price_usd, category, chain, require_healthy |
get | Get full details + ready-to-paste call template for a service. Returns the service card with payment, call, quality, resource samples, and ready-to-use MCP/x402 call hints. Use this after `search` or `ask_services` before paying/calling an Inputs: slug |
get_mcp_server | Get the full card for one MCP server by slug. Inputs: slug |
list_categories | List all available service categories in the directory. |
register | Self-register an x402 / MCP service in the agent-tools directory. Service owners and agents may submit new services here. Submissions are auto-reviewed instantly by x402 verification (no human gate): if the URL proves x402 payment support i Inputs: url, name, description, mcp_url, category, chains |
scan_mcp_safety | Check an MCP server for malware / prompt-injection lures by its endpoint URL. Give the server's streamable-http endpoint URL. Two paths: * **Already in the agent-tools directory** → returns our LATEST stored rule verdict. Every indexed serv Inputs: endpoint_url, name, description, tools_text |
search | Find x402 / MCP services matching an intent or filter set. Two usage modes (agents pick whichever fits): A. Natural-language: `search(intent="fetch tweets for @user")` B. Pure browse: `search(has_mcp=True, category="defi", top_k=10)` At lea Inputs: intent, top_k, max_price_usd, category, chain, min_confidence |
search_a2a_agents | Find A2A agents you can delegate a task to. Args: intent: Natural-language description of the task to delegate. top_k: Max agents to return (1-20). x402_only: When true, only return agents that advertise x402 payment. Inputs: intent, top_k, x402_only |
search_mcp_servers | Find MCP servers in the directory. Searches the standalone MCP directory (PulseMCP / official MCP registry import) unioned with x402 services that also expose an MCP endpoint. Returns normalised entries with a ready-to-use streamable-http ` Inputs: intent, top_k, chain, require_healthy |
search_resources | Unified search across x402 services, MCP servers and A2A agents. Args: intent: Natural-language query. protocol: Optional filter: "x402", "mcp" or "a2a". top_k: Max resources to return (1-50). Inputs: intent, protocol, top_k |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://agent-tools.cloud/mcp-discovery/. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.agenttools-cloud. Endpoint host: agent-tools.cloud. ARD identifier: urn:air:io.github.agenttools-cloud:mcp:agent-tools-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
