How do I use Vaultfire MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Vaultfire MCP Server verify the trust score for agent 0x742d35Cc6634C0532925a3b844Bc9e" 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.

⚠️ Alpha Software — Vaultfire Protocol is in active development. Smart contracts are deployed on mainnet but have not been formally audited by a third-party security firm. Read-only tools are safe for any agent. Write tools interact with live contracts and transactions are irreversible. Use at your own risk. See LICENSE for warranty disclaimers.

@vaultfire/mcp-server

MCP server for Vaultfire Protocol

On-chain trust verification for any MCP-compatible AI. Works with Claude · Copilot · Cursor · Windsurf · Google ADK and more.

Deployed on Base · Avalanche · Arbitrum · Polygon.

npm version License: MIT

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:

AI Accountability Bonds — real economic skin-in-the-game, not just scores
AI Partnership Bonds — mutual economic stakes between agents
Belief-weighted governance — first in industry (not token-weighted)
Cross-chain from day one — 4 mainnet chains
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
