Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Issue verifiable credentials from AI agents for $0.10 via x402. On-chain on Celo, IPFS-pinned.
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.
Pick the AI app you use, then copy the settings.
HASHPROOF_API_KEY, HASHPROOF_WALLET_PRIVATE_KEY, HASHPROOF_X402_NETWORKValues marked secret are keys to your account. Never share them or paste them into a chat.

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.

Verifiable credentials with IPFS backup, on-chain registry, and pay-per-call API via x402.
HashProof is a credential issuance API. Organizations and Individuals (entities) issue verifiable credentials to people. Each credential is:
CredentialRegistry contract on Celohttps://hashproof.dev/verify/:idTwo ways to pay: micropayment in USDC via x402 (Base or Celo) — no API keys, no subscriptions — or a prepaid API key for enterprise clients (no crypto needed). AI agents can call the API directly using a funded wallet.
backend/ Express API — credential issuance, verification, payments
frontend/ React app — landing page, credential verification, entity pages contracts/ CredentialRegistry smart contract (Celo) mcp/ MCP server (hashproof-mcp on npm) — use HashProof from any AI agent skills/ Agent skill (npx skills add csacanam/hashproof) docs/ Architecture and flow documentation
| Network | Contract | Address |
|---|---|---|
| Celo mainnet | CredentialRegistry | 0x7a1B759A602Aba72a70f99Dffd0a386d7504ce9B |
| Endpoint | Price | Description |
|---|---|---|
POST /issueCredential | $0.10 USDC | Issue one verifiable credential |
POST /entities/:id/verificationRequests | $49 USDC | Submit a verification request |
Payment is in USDC on Base or Celo via x402. The client signs an off-chain authorization — no gas required.
| Endpoint | Description |
|---|---|
GET /verify/:id | Full 3-layer verification |
GET /templates/:ref/requirements | Get required fields for a template |
POST /templates/:ref/preview | Generate a preview PDF with watermark (no cost) |
GET /stats | On-chain credential counters |
HashProof is fully agent-usable — no account, no human onboarding. Three ways in:
io.github.csacanam/hashproof): # local (stdio) — pays per credential with your own wallet via x402, or an API key
claude mcp add hashproof -- npx -y hashproof-mcp
claude mcp add --transport http hashproof https://api.hashproof.dev/mcp
Tools: preview_template (free — iterate custom layouts), issue_credential ($0.10 via x402 or API key), verify_credential and get_template_requirements (free). The remote server has no wallet, so it can't do x402 — it needs Authorization: Bearer . See mcp/README.md.
npx skills add csacanam/hashproof — or read it at hashproof.dev/skill.md.POST /issueCredential returns a 402 challenge any x402-v2 client can pay (USDC on Base or Celo). LLM index: hashproof.dev/llms.txt.Agent identity metadata (ERC-8004 registration-v1): hashproof.dev/metadata.json.
