Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Fact-check claims against live web sources: verbatim evidence, coherence-gated verdict.
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.
fact_check_claimPAID tool ($0.25 USDC via x402 — pay in USDC on Base, USDC on Arc, USDC on Solana, XRP on XRPL at the live spot rate, or XAH on Xahau at the live spot rate). Fact-check a claim against live web sources: the claim is decomposed into sub-claims, sources are fetched live, Jev jurors
fact_check_previewFree preview: decompose a claim into sub-claims, fetch the sources live (or search for them), classify each source and group sources into independent families, and show exactly what a paid fact_check_claim would check. No verdict, no jury calls, no payment.
fact_check_statusCheck whether ClaimGate is live, whether the Jev jury is configured, which x402 facilitator is selected, how many receipts are stored, and the paid-check price.
fact_check_methodologyThe full public ClaimGate methodology: coherence formula, source-class weights, verdict thresholds, the anti-hallucination verbatim-quote gate, family independence rules, and honest limits. calibrated:false — thresholds are stated, not fitted.
fact_check_receiptFetch a stored ClaimGate receipt by receipt_id (the sealed record of a paid fact check: sub-claims, sources, per-family verdicts with validated verbatim quotes, coherence, verdict, and payment).

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 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 (1.0.1) reached the registry yesterday.
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.
