Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Cryptographic identity, SIGIL naming, heartbeat, and passports for AI agents.
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.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"provenonce": {
"command": "npx",
"args": [
"-y",
"@provenonce/mcp"
]
}
}
}Run this in your terminal
claude mcp add provenonce -- npx -y @provenonce/mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"provenonce": {
"command": "npx",
"args": [
"-y",
"@provenonce/mcp"
]
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Paste into .vscode/mcp.json in your project

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 0 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).
The GitHub repo last changed –, and the latest version (1.1.4) reached the registry 8 months ago.

Provenonce Skill — Give any AI agent cryptographic identity in under 60 seconds.
Add this skill to your agent and it gets:
Add to ~/.claude/claude_desktop_config.json:
{
"mcpServers": { "provenonce": { "command": "npx", "args": ["-y", "@provenonce/mcp"] } } }
That's it. On first use, your agent calls provenonce_register and gets a permanent identity.
{
"mcpServers": { "provenonce": { "command": "npx", "args": ["-y", "@provenonce/mcp"], "env": { "PROVENONCE_API_KEY": "pvn_...", "PROVENONCE_AGENT_HASH": "0x..." } } } }
If you're a developer embedding this skill in your framework, include your partner ref token:
{
"env": { "PROVENONCE_SKILL_REF": "your16hextoken" } }
You earn 30% of every SIGIL purchased by agents you deploy. Register at POST /api/v1/skill/register.
| Tool | What it does | Auth needed |
|---|---|---|
provenonce_register | Auto-register agent, get hash + API key | None |
provenonce_status | Full current state (SIGIL, balance, hints) | Yes |
provenonce_purchase_sigil | Buy SIGIL, unlock heartbeat + passport | Yes + SOL tx |
provenonce_heartbeat | Submit liveness proof | Yes + SOL tx |
provenonce_batch_heartbeat | Heartbeat multiple children in one call | Yes + SOL tx |
provenonce_get_passport | Get signed identity document | Yes |
provenonce_beats_proof | Compute work proof, get receipt (for spawn/resync) | None |
provenonce_submit_beats | Compute VDF beats and credit lifetime beat count | Yes |
provenonce_verify_agent | Check another agent's identity | None |
provenonce_spawn | Spawn a child agent | Yes |
provenonce_get_lineage | Get full ancestry chain | None |

Credentials are stored in ~/.provenonce/config.json with chmod 600 permissions (Unix).
On Windows, use environment variables (PROVENONCE_API_KEY + PROVENONCE_AGENT_HASH) — file permissions are not enforced.
