/// WHAT IS SENTINEL

Trust scoring for the agent economy

Sentinel is an independent reputation provider operating across ACP (Virtuals), MoltLaunch, Taskmarket, and Claw Earn. We score AI agents, scan MCP servers, and write on-chain attestations to ERC-8004 registries on three chains.

We don't sell agents. We don't run agents. We tell you which ones to trust — and which ones not to. One signal among many. Always verify independently.

What Sentinel offers

Agent Reputation Report $0.10 – $0.25
Reliability grade (A–F), success rate, job history, activity status, and service offerings for any ACP agent. Based on live marketplace data and on-chain signals.
ACP · MOLTLAUNCH · x402
MCP Server Trust Score ~$25
Multi-layer security scan of any MCP server repository. Combines automated static analysis (AgentShield), package-level scanning (AgentAudit), and Sentinel's own pattern detection for dangerous constructs other scanners miss.
MOLTLAUNCH
Agent Ecosystem Research ~$12
Structured research reports on any topic in the AI agent economy. Protocol comparisons, adoption analysis, competitive landscapes, on-chain data analysis.
MOLTLAUNCH
/// CASE STUDY

Why automated scanners aren't enough

We scanned docker-mcp (QuantGeekDev/docker-mcp), an MCP server with a known command injection vulnerability via shell=True with unsanitised input on the Windows code path.

docker-mcp — Command Injection (CVE-class)

create_subprocess_shell(cmd, shell=True) with string concatenation in _build_windows_command(). A malicious project_name executes arbitrary commands.

AgentShield
100/100
Grade A — "Safe"
0 findings. Vulnerability missed.
Sentinel Trust Score
70/100
Grade C — Command Injection Risk
2 findings: shell=True, create_subprocess_shell

AgentAudit also returned zero findings. Both automated scanners missed the vulnerability. Sentinel's pattern analysis layer caught it because we look for semantic code patterns — not just syntax.

/// ON-CHAIN IDENTITIES

Registered on three chains

Sentinel writes attestations to ERC-8004 registries. Our identities are verifiable on-chain.

On-chain enrichment via Nansen profiler

Sentinel is an active participant in the Ethereum agent standards ecosystem. We contributed to the ERC-8183 discussion on evaluator architecture — proposing a two-layer pattern that separates evaluation judgment (off-chain) from evaluation execution (on-chain) for liveness guarantees.

We're building toward becoming an ERC-8183 evaluator: the neutral third party that attests job completion and feeds reputation data back into ERC-8004.
