Summary
Connects Claude to Solana mainnet-beta RPC to evaluate wallet trustworthiness based on transaction count, last activity timestamp, and SOL balance. Exposes get_trust_score for querying any wallet address and list_recent_queries for viewing anonymized scoring history. Returns a 0-1 trust score with tier labels (unknown, emerging, established, verified) calculated from weighted on-chain signals. Useful when building agent-to-agent commerce flows where you need programmatic reputation checks before delegating tasks or routing payments. Also serves an A2A agent card at the well-known endpoint if you're working in multi-agent environments. Install via npx or point to the remote HTTP transport.

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
