## When to Use

✅ **USE this skill when:**

- "Verify my identity for an AI agent"
- "Run a Soulprint validator node"
- "Add identity verification to my MCP server or API"
- "Check the reputation score of a bot or DID"
- "Generate a privacy proof from a Colombian cédula"
- "Verify a cédula against Registraduría Nacional"
- "Issue or verify an SPT (Soulprint Token)"

❌ **DON'T use this skill when:**

- Storing or transmitting biometric data remotely (Soulprint runs 100% locally)
- Verifying identities from countries not yet supported (only Colombia is full)

## Quick Start

### 1. Verify Your Identity (one-time)

---

## Integrate in Your API

### MCP Server (3 lines)

## Trust Score (0–100)

| Component | Max | Source |
|---|---|---|
| Email verified | 8 | credential: email |
| Phone verified | 12 | credential: phone |
| GitHub account | 16 | credential: github |
| Document OCR | 20 | credential: document |
| Face match | 16 | credential: face_match |
| Biometric proof | 8 | credential: biometric |
| Bot reputation | 20 | Validator attestations |
| **Total** | **100** | |

## Protocol Constants (on-chain via ProtocolThresholds)

| Constant | Value |
|---|---|
| `SCORE_FLOOR` | 65 |
| `VERIFIED_SCORE_FLOOR` | 52 |
| `MIN_ATTESTER_SCORE` | 65 |
| `DEFAULT_REPUTATION` | 10 |
| `IDENTITY_MAX` | 80 |
| `REPUTATION_MAX` | 20 |

## Country Support

| Country | Document | Status |
|---|---|---|
| 🇨🇴 Colombia | Cédula de Ciudadanía | ✅ Full (OCR + MRZ + face match + Registraduría) |
| Others | — | 🚧 Planned |

---

## npm Packages

| Package | Version | Purpose |
|---|---|---|
| `soulprint-network` | 0.6.4 | Validator node (HTTP + blockchain clients) |
| `soulprint-mcp` | latest | MCP middleware |
| `soulprint-express` | latest | Express/Fastify middleware |
| `soulprint-core` | latest | DID, tokens, protocol constants |
| `soulprint-zkp` | latest | ZK proofs (Circom + snarkjs) |
| `soulprint-verify` | latest | OCR + face match |
| `soulprint` | latest | CLI |

## Integration with mcp-colombia

`[email protected]` uses Soulprint natively — no extra setup needed.

- `soulprint_status` tool available directly in mcp-colombia: checks on-chain identity and reputation
- `trabajo_aplicar` (job applications) requires Soulprint score ≥ 40
- Live validator: `https://soulprint-node-production.up.railway.app`

### Install both together

User verifies once → ZK proof generated locally (no Registraduría scraping)
→ Nullifier registered on-chain (Base Sepolia)
→ Any agent queries on-chain: isRegistered(nullifier) → true/false
No P2P sync, no central server — blockchain IS the network
