Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Every tool a builder signs up for, on one tab: trials, burn, price drift. Local JSONL, zero deps.
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.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Hermes discovers the skills at https://scvd.store/.well-known/skills/index.json. Connection and no-spend rehearsal guidance covers Hermes, OpenClaw, Skills CLI and chat sessions. A rehearsal ends with the quote, missing capabilities and required approvals; it does not spend. Tested versus untested paths.
mcp-name: store.scvd/general-store
Discovery records: Neuronto, WellKnown, Licium — MCP endpoint history, and Zero.xyz — Signature Agent Card. The Desvela checker runs a check of this domain's discovery surfaces. These are third-party readings of publication and indexing, not evidence of visits or purchases. The WellKnown badge above is served live by WellKnown.
Every badge above is somebody else's reading of this store. This one is ours, about ourselves, and it is set apart from that row on purpose — it is the same artifact we ask operators to paste beside their own doors, pointed back at us, and it says SELF-OBSERVED on its face because the weekly census structurally cannot probe its own host:
It goes dark rather than stale-green: it renders only while every self-module agrees, and any disagreement renders the passport indeterminate and refuses the chip. Weigh it accordingly — the reason it is worth showing at all is that every claim inside it is re-checkable at the public surfaces it names.
scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Signed observations are dated with explicit gaps; free inspection is unsigned. Not escrow, not a rating, not a guarantee.
Three paths, in that order. Before you pay: preflight any x402 door, free, at scvd.store/api/preflight/v1. After you pay: check any issuer's signed offer or receipt, free, at scvd.store/conformance. Over time: read the dated, Bitcoin-anchored corpus, free, at scvd.store/corpus, cite it by DOI (10.5281/zenodo.22284887), or pull it from Hugging Face. Every verdict is ed25519-signed, dated, and verifiable offline without asking us, including the gaps we count against ourselves. Operated by Record Creative Co. LLC.
For working examples, use the SDK and evidence paths: check an endpoint, verify an artifact, reproduce the corpus findings, or attach one dated observation to a listing.
Not an escrow, a guarantor, or a dispute court. Those absorb the risk between payment and delivery and need a balance sheet; we observe that gap and sign what we saw. If you are building escrow or adjudication, this is the layer underneath you rather than a competitor. That direction was decided and dated on 2026-08-07, in the open — the reversal sits beside what it replaced at scvd.store/becoming.
It is also a small, sincere general store for autonomous AI agents, kept by a human out of Oak City, where you're never late. Agents pay in USDC over x402 on a network offered in the current payment quote. Humans read the receipts.
Live at scvd.store. Agents should start at /agents.md (the scannable contract index), /llms.txt (full prose), or /menu.json.

Your agent reads the current menu, shows the price, helps with a compatible wallet if needed, and returns the artifact and verified receipt. Reading and quotes are free. Funding and each purchase need your approval. Availability of payment tools depends on your agent's environment; installation alone does not make it a wallet.
