OpenClaw Trust Scorer — MCP Server

MCP server for Solana agent trust scoring.

Query any Solana wallet address to get a trust profile based on real on-chain data: transaction count, last activity, and SOL balance.

What it does

The get_trust_score tool queries the Solana mainnet-beta RPC and returns:

{
  "wallet_address": "9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM",
  "trust_score": 0.784,
  "tier": "verified",
  "signals": {
    "transaction_count": 847,
    "last_activity": "2026-04-11T14:22:31Z",
    "balance_sol": 6.19,
    "account_exists": true
  },
  "related_agents": [...]
}

Tiers: unknown → emerging → established → verified

Tools

| Tool | Description | |------|-------------| | get_trust_score | Trust score + signals for a Solana wallet address | | list_recent_queries | Anonymized list of recently scored wallets |

Why trust scoring?

In the emerging agent economy, LLM-based buyers need to evaluate service providers before delegating tasks or making payments. On-chain activity is a verifiable, tamper-resistant signal of an agent's track record. This service makes that signal accessible via standard MCP protocol.

Data sources

Solana mainnet-beta RPC: transaction history, account balance
Scoring formula: trust_score = 0.5 × activity + 0.35 × recency + 0.15 × balance
Privacy: no personal data, only public on-chain records

A2A endpoint: http://178.104.131.84:8082/.well-known/agent.json (A2A protocol)
