Tools 23 found in our last check

• 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 least one of `intent`, `category`, `chain`…

• 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 selected recommendations. If the LLM is una…

• 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 external service. Args: slug: Service s…

• list_categories

  List all available service categories in the directory.

  High-level stats about the directory: x402 total, healthy count and chains, plus `snapshot`, the daily digest across x402, MCP and A2A (see directory_stats).

• get_methodology

  How every score and statistic on agent-tools.cloud is computed. Returns the quality-score components and grade bands per protocol, the nine readiness criteria with weights, payment-evidence grades, the probing schedule and the definitions behind the daily statistics.

• list_articles

  List published Blog articles, newest first (metadata only). Args: query: Optional words to match in title, summary or body. tag: Optional tag to filter by. page: Page number, 20 articles per page. Use get_article(slug) for the full Markdown body.

  Read one published Blog article: metadata plus the full Markdown body. Args: slug: The article slug, as returned by list_articles.

• directory_stats

  Daily statistics on the agent-tool ecosystem as seen by our probes. Args: view: "all", "mcp", "x402" or "a2a" to scope the figures to one protocol. topic: Optional topic word (e.g. "payment", "weather") to get that topic instead: supply per protocol, readiness, best listings, se…

• 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 `call_hint.mcp.url`. Args: intent: Natur…

• get_mcp_server

  Get the full card for one MCP server by slug. Args: slug: MCP server slug as returned by `search_mcp_servers` items.

• 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.

  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 it is listed immediately and shows up in…

• 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 server is re-scanned hourly, so you get a c…

• claim_service_url

  Issue a fresh ownership token for one exact public HTTPS URL. Authenticate in the MCP Authorization: Bearer header. Publishing and verifying the token is required before editing; URL input alone grants no rights. Args: url: Complete public HTTPS service URL, including its query…

• verify_service_url

  Verify public ownership proof for your own exact service URL claim. This reads public proof only. It never calls business tools, requests private service credentials, or grants whole-platform permissions. Args: claim_id: Claim id returned by claim_service_url. token: The issued…

• get_owned_listing

  Read editable metadata for a listing covered by your verified claim. Args: kind: Listing type: x402, mcp, or a2a. slug: Slug from the verified claim's listings or directory search.

• prepare_paid_verification

  Quote a sponsored paid verification of an x402 service. You pay the service once from your own wallet (Base USDC, <= $1; funds go to its payTo). Sign the returned `typed_data` (EIP-712), then call `execute_paid_verification` before `valid_before`. We never sign or hold funds. Au…

• execute_paid_verification

  Send the signed payment to the service once and score the result. Aborts without paying if price or recipient changed. Never retried; a timeout returns `indeterminate`. status: succeeded | delivery_failed | payment_rejected | indeterminate. Args: id: `id` returned by `prepare_pa…

• get_paid_verification
