@followed by the MCP server name and your instructions, e.g., "@DPYC Oraclewhat's the current tax rate?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
DPYC Oracle
A free, unauthenticated MCP concierge service for the DPYC Social Contract. The Oracle answers questions about membership, governance, onboarding, and tax rates by reading the dpyc-community GitHub registry live. No credits, no Neon database, no Secure Courier, no payment or credentials required.

| Publish a pricing campaign to the DPYC community |
|
| List published pricing campaigns, optionally filtered by operator or author |
|

Citizenship Onboarding
New citizens can self-register via Schnorr signature verification:
request_citizenship(npub, display_name)— issues a cryptographic challengeSign the challenge with your Nostr nsec (offline, nsec never leaves your device)
confirm_citizenship(npub, challenge_id, signed_event_json)— verifies signature and auto-commits
On success, the Oracle creates an individual member file at members/citizens/{npub}.json in dpyc-community. The CI workflow auto-regenerates members.json from individual files.
Advocate Registration
Advocates are community utility services (e.g., OAuth2 collectors) that provide shared infrastructure but aren't monetized Operators. Registration is Oracle-mediated — no challenge-response needed:
register_advocate(
npub="<service_npub>",
display_name="My Service",
service_name="my-service",
service_url="https://my-service.fastmcp.app",
service_description="What the service does",
)The Oracle commits members/advocates/{npub}.json directly. Peer MCP servers discover the service URL via resolve_service_by_name() in the tollbooth-dpyc registry client.
How to Connect
This service is hosted on Horizon. Add it to your MCP client configuration:
{
"mcpServers": {
"dpyc-oracle": {
"url": "https://dpyc-oracle.fastmcp.app/mcp"
}
}
