Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read current software facts with primary-source evidence and verification timestamps.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
xguard.fact.getRead 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.capabilitiesReturn the enabled and disabled XGuard tools, their security boundary, and canonical discovery URLs. Free.
xguard.preflightFree, 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
xguard.pricing.quoteGet an optional signed quote for xguard.web.fetch. Call xguard.web.fetch directly to receive the price in an HTTP 402 challenge.
xguard.web.fetchFetch one public HTTPS resource after x402 v2 payment and on-chain settlement verification. Retry the identical MCP call with Payment-Signature and X-XGuard-Quote. A completed retry returns the prior receipt.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (6.0.0) reached the registry 3 days ago.
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.

[XGuard Extract](https://xguardgate.com/extract): up to 3 public web pages → clean text, metadata, links and source evidence in one JSON result. 0.012 USDC per request, paid with x402 v2 on Base.
Use the browser wallet checkout or POST https://api.xguardgate.com/api/paid/v1/extract with an Idempotency-Key and {"urls":["https://example.com/"],"max_amount_atomic":"12000"}. The initial request returns 402 without retrieving the supplied pages. A funded x402 client authorizes the exact offer, then retries the same body and key with Payment-Signature and X-XGuard-Quote.
No subscription or XGuard API key. Public HTML/text/JSON only; no browser rendering, sign-ins, search or access-control bypass. Up to 128 KiB source input and 6,000 extracted text characters per page. Partial success reports coverage; all-source failure after settlement creates an operation-specific execution credit, not an automatic cash refund. API and recovery contract · JavaScript client.
The live facts layer for AI.
Current facts. Source verified. Change tracked. Machine readable.
XGuard Live observes public primary sources and publishes compact, canonical facts with verification timestamps, source evidence and immutable history. People and machines retrieve the same data through ordinary HTTP. No account, SDK, plugin or paid API key is needed for public facts.

A published observation includes the current or last observed value, source URL, source hash, observed/verified timestamps, freshness limit, previous value and history. STALE/UNKNOWN never imply a current verified value. Verification means a match to the source at retrieval, not independent certification of every publisher claim. Candidates remain unpublished until schema and source checks pass.
Use XGuard Live's MCP endpoint with Streamable HTTP and call xguard.fact.get with {"factId":"npm/react/latest-version"}. Free public fact reads need no account or API key. Install in your client or use the A2A agent card.

Local development uses a separate Worker config and local SQLite Durable Objects. Production smoke checks are read-only and excluded from business metrics: npm run smoke. The primary-source check is node scripts/live-source-check.mjs; robots restrictions, rate limits and changed source schemas can legitimately prevent collection.
The production Worker is xguard-mainnet. Cron runs every ten minutes; persistent shard alarms collect due sources with domain limits and backoff. Cloudflare cache serves bounded, format-specific representations. /healthz exposes real counts and scheduler health. /admin requires an owner key and protects all mutations.
Deployment: use a pull request, pass CI/CodeQL, merge, then the Deploy XGuard Live workflow deploys the tested commit. Manual deployment with existing Cloudflare credentials: npx --prefix apps/relay wrangler deploy --config apps/relay/wrangler.jsonc --tag git-$(git rev-parse --short=12 HEAD). Production lifecycle changes must first pass node scripts/durable-object-deploy-guard.mjs HEAD and be isolated from runtime changes.
See operations and rollback and migration inventory. The former execution gateway is retained solely for state/recovery compatibility and historical reference; it is not the public Live product. Historical result recovery still requires its original signed quote. Legacy marketing and release workflows are archived and do not run.
Launch mode is observe. Cloudflare Pay Per Crawl eligibility and Pay Per Use buyer participation require confirmation in the owner's Cloudflare account. The application does not fabricate revenue, simulate paid production traffic or equate crawler requests with paid use. Actual provider report imports and invoice costs are separate, auditable records. No report means unknown account revenue, not proven zero. Discovery remains free even when eligible high-value detail pages are later configured for paid retrieval.
