About
DoI score lookup, vouch event builder, and offline schnorr verify for AI agents.
Security Report
This is a well-structured MCP server for Nostr identity verification with proper separation of concerns and reasonable security practices. The server intentionally remains stateless and key-free, delegating payment handling to the caller. No critical vulnerabilities or data exfiltration patterns detected. Minor code quality observations exist but do not materially affect security. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

@powforge/mcp-identity
MCP server that scores any Nostr pubkey's depth-of-identity before your handler runs. Chaintip-anchored Schnorr cert, L402 priced, drop-in for AI agents that need Sybil resistance on top of paid APIs.
npm: npm i @powforge/mcp-identity
Homepage: https://powforge.dev/explorer
Whitepaper: https://powforge.dev/whitepaper
What It Does
Three MCP tools that wrap the PowForge Depth-of-Identity Oracle:
doi_score_lookup— given a Nostr pubkey (hex or npub), returns multi-dimensional identity score (network, longevity, kinetic-filter cost). L402-priced via the upstream oracle.doi_sign_vouch— builds an unsigned Nostr event for vouching depth-of-identity for another pubkey. Caller signs; oracle counts toward score on observation.doi_score_verify— offline Schnorr verification of a signed DoI cert returned from the oracle. No network.
Why Identity-Anchored Pricing
Most paid-API services charge per-request flat. That fails on agent-to-agent surfaces where:
- New agents look identical to scrapers — no signal on intent or risk.
- Long-tail abusers extract value cheaper than they impose cost.
- Whitelist gating doesn't scale to open agent ecosystems.
DoI gives your server a quantitative number for "how much would it cost to fake this caller's identity at this depth" — anchored to a specific Bitcoin chaintip cert that's non-repudiable. Use it as a multiplier on your L402 macaroon price, a rate-limit input, or a routing key.
Quick Start
npm i @powforge/mcp-identity
Add to your MCP config (Claude Desktop, Cursor, etc):
{
"mcpServers": {
"powforge-identity": {
"command": "npx",
"args": ["-y", "@powforge/mcp-identity"]
}
}
}
Restart the client. Three new tools appear under powforge-identity.
Why Chaintip-Anchored
The score includes a Schnorr signature over (score, dimensions, score_chaintip_height, score_chaintip_blockhash). That binds the claim to Bitcoin's kinetic filter — recomputable PageRank scores can be silently rewritten, but a chaintip-anchored cert is a fixed claim against a known time. Verification is offline.
The oracle's falsifiable claim window is documented in the whitepaper.
L402 Pricing
The MCP server transparently handles the L402 macaroon dance with oracle.powforge.dev. First call returns a 402 with a Lightning invoice; the wrapper pays from a wallet you configure (env: LNBITS_INVOICE_KEY) and retries. No keys, no accounts.
Status
- v0.7.0 published to npm 2026-04-28.
- Three tools exposed.
- Cert format documented in the whitepaper.
- Oracle availability monitored at https://powforge.dev/oracle/freshness.
