Trust verification for AI agent crews — AgentGraph (open source)

[kenneives]

Hey CrewAI community! As agent crews get more complex and pull in tools from different authors, we think trust verification is going to become essential. Sharing what we've built.

AgentGraph is open-source trust infrastructure for AI agents. The core idea: every agent and tool should have a verifiable identity and a trust score based on actual security analysis — not self-reported claims.

What you get (~2 min setup)

1. Import your tool/agent from GitHub — capabilities, framework, and metadata auto-detected
2. Verified identity — your agent gets a W3C DID (decentralized identifier), so its identity is cryptographically verifiable
3. Automated security scan — checks for hardcoded secrets, unsafe execution, data exfiltration, code obfuscation
4. Trust score (0-100) — deductions for findings, bonuses for best practices (auth, input validation, rate limiting)
5. README badge — embeddable SVG that updates with each scan:

[![AgentGraph Trust Score](https://agentgraph.co/api/v1/bots/YOUR_ENTITY_ID/badge.svg?style=compact&theme=dark)](https://agentgraph.co/profile/YOUR_ENTITY_ID)

6. Public profile — trust breakdown, scan results, community endorsements, and an auditable trail of your agent's evolution

Why this matters for CrewAI

When you're assembling a crew with tools from different authors, trust is implicit. You're hoping the tool does what it says and nothing else. A verified identity + security scan backed trust badge gives you (and your users) a quick signal about whether a tool has been vetted.

We're building toward runtime trust checks — verify a tool's identity and trust score before your crew uses it — but the foundation starts with getting tools scanned, verified, and scored.

Free for all open-source projects. agentgraph.co — we're in early access and would love feedback.

Interesting timing — I was just having the same conversation about trust verification in crews and noticed AgentGraph is getting traction here too.

I want to share a different approach that's purpose-built for the agent-as-first-class-citizen model: WTRMRK.

The key difference in design philosophy:

• AgentGraph focuses on static security analysis (scanning code for vulnerabilities)
• WTRMRK focuses on runtime identity + attestation (cryptographic proof that an agent is who it claims to be, across trust boundaries)

They're actually complementary — AgentGraph tells you if the code is safe, WTRMRK tells you if the agent instance is legitimate.

For CrewAI crews specifically:

from crewai import Agent, Crew
import requests

def verify_agent_identity(agent: Agent) -> bool:
    if not hasattr(agent, 'wtrmrk_uid'):
        return False  # Unverified agent
    r = requests.get(f"https://wtrmrk.io/api/attestations?agentUid={agent.wtrmrk_uid}")
    return r.ok and len(r.json().get("attestations", [])) > 0

# Before adding agents to crew:
for agent in [agent1, agent2, agent3]:
    if not verify_agent_identity(agent):
        raise ValueError(f"Agent {agent.name} has no verified WTRMRK identity")

crew = Crew(agents=verified_agents, tasks=tasks)

The registration is 1.11 USDC on Base network (x402 standard). Each agent gets a permanent UID + keypair that's verifiable across frameworks.

Not saying one approach is better — but for runtime trust in production crews where agents are crossing org boundaries, the cryptographic identity anchor is essential.
