XGuard Live MCP
An MCP server that allows AI agents to retrieve current software facts with primary-source evidence and verification timestamps. It provides access to a live facts layer for AI, grounded in primary sources, enabling agents to query specific facts like npm package versions and view change history without requiring an API key for public reads.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
MCP endpoint (Streamable HTTP)
https://xguardgate.com/mcpWhat its tools do
6 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.
Can change data (1)
Checks and signals
Each line is separate evidence, not a trust score.
- Passed Endpoint answered the live check ·
- Availability 1 of 1 checks passed in 30 days
What you can do with it
- Retrieve current software facts with primary-source evidence
- Query specific fact IDs like npm/react/latest-version
- View immutable change history for published facts
- Connect AI clients via Streamable HTTP for fact retrieval

xguard.fact.get
Advertised read-only
Read one free published software fact by canonical ID. Returns the primary source, verification status and timestamp. Use xguard.web.fetch for a separate paid fetch of a public URL.

}xguard.preflight — Preflight a guarded paid request
Advertised read-onlyOpen-world
Free, read-only safety gate for xguard.web.fetch. Validates the public HTTPS target, SSRF policy, DNS reachability and selected payment path without contacting the target or attempting payment. On allow, call xguard.web.fetch directly; it creates the signed quote and returns the mandatory x402 v2 PaymentRequired result.

Open-world
Extract main text, titles, metadata and links from 1–3 public HTTPS pages into one deduplicated, attributed result. No JavaScript rendering, private pages or web search. Up to 6,000 text characters per page; partial source coverage is explicit. Price: 0.012 USDC on Base. Uses x402 v2 HTTP payment headers: retry identical arguments and idempotency key with Payment-Signature and X-XGuard-Quote; the authorization is for the canonical HTTP API resource. No source is fetched before payment.
