工具名称和描述与服务器在 2026年11月7日报告的完全一致。这些内容由作者撰写，不是我们写的；我们以纯文本形式显示。

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 unav
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 sl
list_categories
List all available service categories in the directory.
stats
High-level stats about the directory: total services, healthy count, sources.
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: Natura
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.
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).
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 it is listed immediately and shows up in
scan_mcp_safety 看起来像是对 AI 下的指令
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 co
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. Aut
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_pai
get_paid_verification
Read one of your own paid verifications. Args: id: Verification id. api_key: Optional if the Authorization header is sent.

mcpserver — agent-tools.cloud directory + MCP discovery

The server that powers agent-tools.cloud — an open directory of x402 paid services with a free MCP discovery endpoint. Also listed on Smithery.

Note (2026-05-25): the previously hosted paid Qwen3.6 relay and the paid

vertical endpoints (signal / onchain / defi / portfolio) were retired after

30 days of zero external conversions. This repository now serves the

directory site and the free MCP discovery server only.

What this serves today

Path	Auth	Purpose
`GET /` (host = `agent-tools.cloud`)	free	Directory site (search / browse)
`GET /api/v1/search`	free	Faceted service search
`POST /api/v1/ask`	free, rate-limited	LLM-ranked recommendations grounded in directory candidates
`GET /api/v1/services/{slug}`	free	Service card with payment, call and quality metadata
`GET /api/v1/categories`, `/api/v1/stats`	free	Directory facets and aggregate stats
`POST /api/v1/submit`	free, rate-limited	Pending service submission with dedupe
`POST /mcp-discovery/`	free	MCP streamable-http discovery server
`POST /a2a`	free	A2A JSON-RPC agent (`message/send`): directory search + MCP safety scan
`GET /healthz`	free	Liveness
`GET /v1/models`	free	Upstream model listing (read-only)
`GET /.well-known/agent-tools.json`	free	Agent discovery manifest
`GET /.well-known/x402`	free	x402 v0.4 self-description (free-only)
`GET /.well-known/mcp.json`	free	MCP self-description

The MCP discovery server is also published as a standalone PyPI package: agent-tools-mcp (repo).

MCP discovery tools

search(intent, top_k=5, category=None, max_price_usd=None, has_mcp=None)

ask_services(intent, top_k=5, category=None, max_price_usd=None, use_llm=True) get(slug) list_categories() stats() search_mcp_servers(intent, top_k=5, chain=None, require_healthy=False) get_mcp_server(slug) search_a2a_agents(intent, top_k=5, x402_only=False) search_resources(intent, protocol=None, top_k=10) scan_mcp_safety(endpoint_url, name="", description="", tools_text="") register(url, name=None, description=None, mcp_url=None, category=None)

search accepts natural-language intent and ranks by FTS5 + popularity + health. Each result carries a match_reason and a confidence score. ask_services uses the same retrieval-first / LLM-rerank flow as /api/v1/ask.

scan_mcp_safety vets an MCP server (by endpoint URL) for malware / prompt-injection lures before you connect: an already-indexed server returns our latest stored verdict, an unknown one is probed live, scanned, and added to the directory. The verdict comes from deterministic static rules (no code execution) over the server's advertised name + description + tool docs. Rules cover pipe-to-shell / base64-eval / PowerShell install cradles, bare-IP payload hosts, prompt-injection phrasing, and MCP tool-poisoning coercion — "always call this tool first", "before using any other tool you must…", hidden instructions, "list all API keys / include secrets in your response", and coercion to read & forward .key/.pem/.ssh/.env files. Source-code-oriented rules (SQL/command/code injection) are intentionally not applied to natural-language descriptions to avoid false positives. Each live call also runs a frontier-LLM second opinion as an advisory dimension. It is also exposed as an A2A skill on POST /a2a. The hosted server carries the full tool set above; the stdio agent-tools-mcp PyPI package ships the core search tools only.

Deploy

Production runs behind nginx (vhost: agent-tools.cloud).

cd <install-dir>

sudo git pull sudo systemctl restart mcpserver

systemd units live in deploy/:

mcpserver.service — the ASGI app (uvicorn, 127.0.0.1:9100)
agent-tools-crawl.{service,timer} — 6h directory crawler
agent-tools-health.{service,timer} — endpoint health checks

Config

See .env.example. Required:

UPSTREAM_BASE_URL / UPSTREAM_API_KEY — used by /v1/models
AGENT_TOOLS_ASK_BASE_URL / AGENT_TOOLS_ASK_API_KEY / AGENT_TOOLS_ASK_MODEL — LLM backend for /api/v1/ask
AGENT_TOOLS_SAFETY_BASE_URL / AGENT_TOOLS_SAFETY_API_KEY / AGENT_TOOLS_SAFETY_MODEL — optional override for the scan_mcp_safety advisory LLM (falls back to the AGENT_TOOLS_ASK_* backend)
AGENT_TOOLS_DB_PATH — SQLite path for the directory
AGENT_TOOLS_ASK_RATE_LIMIT_PER_MINUTE / AGENT_TOOLS_ASK_RATE_LIMIT_PER_DAY — public ask abuse limits
METRICS_BEARER_TOKEN — optional remote access token for /metrics; without it metrics are local-only
