此 MCP 可以做什么

Fetches web pages as Markdown or metadata, exposes a digital-goods catalog, and scans remote MCP tool descriptions for poisoning patterns.

get_agent_census

Get Agent Web Crawler Census

Return the Agent Web Crawler Census: every named bot observed crawling a live, publicly-listed x402 + MCP endpoint over a 24-hour window, each with a case-insensitive regex `matcher` and a behavioural `category` (liveness-monitor, directory-crawler, price-scraper, security-research, ai-training, ...) so you can classify your own access log. Observed first-hand, not aggregated from third-party bot lists. Notable finding: of the named agent-web crawlers in the census, zero have ever presented a payment, and several declare that in their own User-Agent string. Wraps GET /v1/agent-census.json. Free, unmetered, no payment required. CC BY 4.0.

输入模式

{'type': 'object', 'properties': {'category': {'type': 'string', 'description': 'Optional. Return only agents in this behavioural category, e.g. "price-scraper" or "liveness-monitor". Omit for the full census.'}}, 'additionalProperties': False}

get_metadata

Get URL Metadata

Fetch a URL server-side and return structured metadata: title, description, canonical URL, OpenGraph/Twitter card fields, favicon URL, language, and published/modified timestamps when present. Wraps GET /v1/meta. Same free tier as read_url; priced at $0.001/call via x402 once exhausted.

输入模式

{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'Absolute http(s) URL to fetch.'}}, 'additionalProperties': False}

get_purchase_info

Get Purchase Info

Look up a product by id (from list_products) and explain exactly how to buy it: its price, and the x402 purchase flow step by step (the 402 challenge shape, the PAYMENT-SIGNATURE header, and the signed download URL you get back on success). Does not take payment itself — informational only, mirroring the pre-payment leg of GET /v1/buy/:id.

输入模式

{'type': 'object', 'required': ['product_id'], 'properties': {'product_id': {'type': 'string', 'description': "Product id, from list_products' `id` field."}}, 'additionalProperties': False}

list_products

List Products

List Fetchgate's digital-goods catalog: id, name, description, priceUsd, currency, file format, size, sha256, and a walletless humanUrl checkout link for each product for sale. Wraps GET /v1/products. Free, no rate limit, no payment required just to browse.

输入模式

{'type': 'object', 'properties': {}, 'additionalProperties': False}

read_url

Read URL as Markdown

Fetch a URL server-side and return its main content as clean Markdown, with scripts/styles/nav/ads/boilerplate stripped out. Wraps GET /v1/read. Free tier: 30 calls/day per caller; priced at $0.002/call via x402 once that's exhausted (see get_purchase_info for how the x402 flow works). Only http:// and https:// URLs are accepted; private/internal-network hosts are rejected.

输入模式

{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'Absolute http(s) URL to fetch.'}}, 'additionalProperties': False}

scan_mcp_server

Scan an MCP server's tool descriptions for poisoning patterns

Connect to a remote Streamable HTTP MCP server, fetch its tools/list (sends only initialize, notifications/initialized and tools/list — never tools/call) and scan every tool name, description, parameter description and the server's initialize `instructions` string for tool-poisoning patterns: hidden-instruction markers, invisible Unicode, directives aimed at the model, credential/secret references, exfiltration shapes and instructions about other tools. Returns per-tool findings with severity, excerpt and a score band. Use it before installing or trusting a third-party server. Heuristic: a clean result means nothing obvious in what the server declares about itself, not that it is safe. Wraps GET /v1/mcp-scan. Free, rate-limited per caller; private/internal-network hosts are rejected.

输入模式

{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': "The MCP server's Streamable HTTP endpoint URL, e.g. https://example.com/mcp"}}, 'additionalProperties': False}
