Common questions

Is agent-tools (x402 + MCP + A2A directory) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, dotnet-mcp

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
