Quick Start

Claude Desktop

Add to your claude_desktop_config.json (usually at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "vaultfire": {
      "command": "npx",
      "args": ["-y", "@vaultfire/mcp-server"],
      "env": {
        "VAULTFIRE_CHAIN": "base"
      }
    }
  }
}

To enable write tools (register agents, create bonds), add your private key:

{
  "mcpServers": {
    "vaultfire": {
      "command": "npx",
      "args": ["-y", "@vaultfire/mcp-server"],
      "env": {
        "VAULTFIRE_CHAIN": "base",
        "PRIVATE_KEY": "your_private_key_here"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "vaultfire": {
      "command": "npx",
      "args": ["-y", "@vaultfire/mcp-server"],
      "env": {
        "VAULTFIRE_CHAIN": "base"
      }
    }
  }
}

Generic (npx)

# Read-only mode (no key needed)
npx @vaultfire/mcp-server

# With a specific chain
VAULTFIRE_CHAIN=avalanche npx @vaultfire/mcp-server

# With write tools enabled
PRIVATE_KEY=your_private_key npx @vaultfire/mcp-server

Install globally

npm install -g @vaultfire/mcp-server
vaultfire-mcp-server

Available Tools

Read-Only Tools (always available)

Tool	Description
vaultfire_verify_agent	Full trust verification: identity, bonds, Street Cred, reputation, bridge status
vaultfire_get_street_cred	Get Street Cred score (0-95) and tier
vaultfire_get_agent	On-chain identity data (URI, type, registration date, active status)
vaultfire_get_bonds	All partnership bonds for an address
vaultfire_get_reputation	Reputation data (average rating, feedback count, verified %)
vaultfire_discover_agents	Find agents by capability tags
vaultfire_protocol_stats	Protocol stats: total agents, bonds, bonded value, bridge sync

Write Tools (require PRIVATE_KEY env var)

Tool	Description
vaultfire_register_agent	Register an AI agent on-chain (ERC-8004)
vaultfire_create_bond	Create a partnership bond with economic stake

Warning: Write tools submit real transactions to mainnet. Transactions are irreversible.

Resources

The server exposes two MCP resources for protocol context:

URI	Description
vaultfire://chains	All 4 supported chains with contract addresses and chain details
vaultfire://scoring	Street Cred scoring formula and tier definitions

---

Configuration

Environment Variable	Required	Default	Description
VAULTFIRE_CHAIN	No	base	Chain to query: base, avalanche, arbitrum, polygon
PRIVATE_KEY	No	—	Private key for write tools (register, bond). Never commit this.
VAULTFIRE_RPC_URL	No	—	Custom RPC URL (overrides default for selected chain)

---

Street Cred Scoring

Street Cred is a composite trust score (0–95) computed from live on-chain data:

Component	Points	Condition
Identity Registered	30	Agent has ERC-8004 on-chain identity
Has Bond	25	At least one partnership bond exists
Bond Active	15	At least one bond is currently active
Bond Tier	0–20	Platinum (≥0.5 ETH) / Gold (≥0.1) / Silver (≥0.05) / Bronze (≥0.01)
Multiple Bonds	5	More than one bond (ecosystem participant)

Tiers:

Tier	Score Range	Description
Unranked	0	No on-chain trust signals
Bronze	1–30	Basic identity or minimal bond activity
Silver	31–55	Registered and bonded with some stake
Gold	56–75	Active bond with meaningful stake
Platinum	76–95	Multiple active bonds with significant stake

---

Supported Chains

Chain	Chain ID	Hub	Native Token
Base	8453	✅ Primary	ETH
Avalanche	43114	—	AVAX
Arbitrum	42161	—	ETH
Polygon	137	—	POL

Why Vaultfire

Feature	Vaultfire	AxisTrust	Cred Protocol	Okta XAA
AI Accountability Bonds	✅	❌	❌	❌
AI Partnership Bonds	✅	❌	❌	❌
On-chain, trustless	✅	❌	partial	❌
Multi-chain (day one)	✅ (4)	❌	❌	❌
Street Cred composite score	✅	T-Score	C-Score	❌
Belief-weighted governance	✅	❌	❌	❌
ERC-8004 compliant	✅	❌	✅	❌

Morals over metrics. Privacy over surveillance. Freedom over control. Making human thriving more profitable than extraction.

Core differentiators:

1. AI Accountability Bonds — real economic skin-in-the-game, not just scores
2. AI Partnership Bonds — mutual economic stakes between agents
3. Belief-weighted governance — first in industry (not token-weighted)
4. Cross-chain from day one — 4 mainnet chains
5. Street Cred scoring — composite 0-95 trust score from on-chain data

Security

• Read-only tools require no credentials and are safe to run anywhere
• Write tools require PRIVATE_KEY — always load from env vars, never hardcode
• Smart contracts are deployed on mainnet but have not been formally audited
• Transactions sent via write tools are irreversible
• Do not expose your MCP server config (with PRIVATE_KEY) to untrusted parties
