modbender Trusted ClawMon
A read-only trust registry lookup for MCP skills, built on ERC-8004 and Monad.
What it does
Trusted ClawMon is a trust score lookup service. It lets agents query reputation data for MCP skills before using them. All lookups are read-only HTTPS GET requests that return JSON — no signing, no wallet connection, no credentials required.
Connection
| Setting | Value |
|---|---|
| Base URL | https://trusted-clawmon-api.up.railway.app |
| Protocol | HTTPS only (TLS required) |
| WebSocket | wss://trusted-clawmon-api.up.railway.app/ws (read-only event stream) |
| Authentication | None — all read endpoints are public |
| Rate limit | Standard HTTP rate limiting applies |
Required environment variables
None. This skill performs read-only HTTPS lookups against the public ClawMon API. No API keys, private keys, wallet connections, RPC endpoints, or signing credentials are needed.
What data is sent
Read-only lookups send only the skill ID in the URL path (e.g., GET /api/agents/gmail-integration). No user data, wallet addresses, input context, or usage telemetry is transmitted.
The optional feedback endpoint (POST /api/feedback) sends a skill ID, a pseudonymous reviewer address, and a numeric score. This is opt-in and never triggered automatically.
Wallet address
The wallet field in the frontmatter (0x3e4A...d7Ed) is the publisher's Monad testnet address for receiving ClawMon protocol revenue. It is not used by the agent, not required for any lookup, and does not grant signing authority. Agents never need to interact with this address.
When to use this skill
When a user asks you to evaluate whether an MCP skill is safe or trustworthy, query ClawMon for its trust score. Do not query ClawMon automatically before every skill call — only when the user requests a trust check or when invoking a skill you have not used before and want to verify.
Read-only API (no credentials needed)
Look up a skill's trust score
GET https://trusted-clawmon-api.up.railway.app/api/agents/:skillId
Returns trust scores and tiers. Key fields in the response:
hardenedScore(0-100) — sybil-resistant scorehardenedTier— trust tier (AAA through C)isSybil— whether the skill was flagged as part of a sybil clusterisStaked— whether the publisher has staked MONteeStatus— TEE attestation status (verified,unregistered,expired)teeCodeHashMatch— whether the code hash matches the pinned version
Get the trust leaderboard
GET https://trusted-clawmon-api.up.railway.app/api/leaderboard
Returns all skills ranked by hardened trust score.
Check staking status
GET https://trusted-clawmon-api.up.railway.app/api/staking/:skillId
Returns stake amount, tier (None/Bronze/Silver/Gold/Platinum), and slash history.
Check TEE attestation
GET https://trusted-clawmon-api.up.railway.app/api/tee/:skillId
Returns TEE verification status, code-hash match, and attestation freshness.
System health
GET https://trusted-clawmon-api.up.railway.app/api/health
Returns API status, version, agent count, and uptime.
Optional: Feedback submission (opt-in only)
Feedback is never submitted automatically. Only submit feedback when the user explicitly asks to rate a skill.
POST https://trusted-clawmon-api.up.railway.app/api/feedback
Content-Type: application/json
{
"agentId": "<skillId>",
"clientAddress": "<pseudonymous-identifier>",
"value": 85,
"tag1": "coding"
}
The clientAddress is a pseudonymous string identifier — it does not need to be a real wallet address. No signing or wallet connection is required.
Optional: x402 payment flows
x402 payment endpoints exist but are entirely optional and are not used by this skill by default. They are documented in the ClawMon API for publishers who want pay-per-use access to their own skills. Agents using ClawMon as a trust lookup never need to make payments.
Trust Tiers
| Tier | Score Range | Meaning |
|---|---|---|
| AAA | 90-100 | Highest trust — well-reviewed, staked, attested |
| AA | 80-89 | High trust |
| A | 70-79 | Good trust |
| BBB | 60-69 | Moderate — use with caution |
| BB | 50-59 | Below average |
| B | 40-49 | Low trust |
| CCC | 30-39 | Very low — likely problematic |
| CC | 20-29 | Near-zero trust |
| C | 0-19 | Untrusted or flagged |
Example
User: "Is the gmail-integration skill safe to use?"
1. GET https://trusted-clawmon-api.up.railway.app/api/agents/gmail-integration
2. Check hardenedTier → "AA" (high trust)
3. Check isSybil → false (not flagged)
4. Check isStaked → true (publisher has skin in the game)
5. Report: "gmail-integration has an AA trust rating (score 84/100), publisher is staked, no sybil flags."
