AskCarX | 12 days ago | on: NemoClaw: Nvidia Is Planning to Launch an Open-Source AI Agent Platform
Nvidia is solving agent deployment and orchestration. But once you have thousands of enterprise agents running autonomously -- making API calls, accessing data, executing code -- who verifies their identity? How do you prove what an agent did? How do you revoke a compromised one instantly?
We built AgentSign for exactly this layer. Cryptographic identity for every agent, signed execution chains, runtime attestation before anything runs. Think of it as the identity infrastructure underneath platforms like NemoClaw.
Deployment without trust verification is how you get another Moltbook situation (went viral for fake agent posts, Meta just acquired it).
AskCarX | 12 days ago | on: Meta acquires Moltbook
We've been building AgentSign (patent pending) which tackles this exact gap -- cryptographic identity for AI agents. Every agent gets an identity certificate, every action gets signed into an execution chain, and there's runtime code attestation before anything executes. Think zero trust but for agents, not humans.
The real question isn't whether agent networks will exist (clearly they will, Meta just paid for one). It's whether we'll let them run without any trust infrastructure underneath. Moltbook without trust verification = fake posts. Agent networks with cryptographic identity = agents you can actually hold accountable.

AgentSign has 5 subsystems (patent pending) and two of them directly address what you're describing:
Compromised agent scenario: Subsystem 3 is Runtime Code Attestation. Before every execution, the agent's code is SHA-256 hashed and compared against the attested hash from onboarding. If agent A gets injected via a malicious document and its runtime is modified, the hash comparison fails and execution is blocked. This isn't a one-time check at onboarding — it runs continuously, pre-execution. A compromised agent can't sign anything because it fails attestation before it gets to sign.
Replay attacks: Subsystem 2 is Execution Chain Verification — a signed DAG of input/output hashes with unique execution IDs and timestamps bound to each interaction. Replaying a signed payload triggers an execution ID collision. Every agent-to-agent call is a unique, signed, timestamped link in the chain.
Trust delegation: AgentSign deliberately has no delegation mechanism. Each agent presents its own passport independently at the verification gate (we call it THE GATE — POST /api/mcp/verify). There's no "agent A vouches for agent B." Every agent is verified on its own identity, its own code attestation, its own trust score. If an attacker controls agent B, they still need B to pass runtime attestation independently — which it won't if the code has been tampered with.
Behavioral integrity: Subsystem 5 is Cryptographic Trust Scoring. It's not static — it factors in execution verification rate, success history, code attestation status, and pipeline stage. An agent that starts producing anomalous outputs drops in trust score dynamically and gets flagged. Identity without behavioral integrity is exactly the gap trust scoring fills.
The five subsystems working together: identity certs, execution chains, runtime attestation, output tamper detection, and trust scoring. Remove any one and you have the gaps you're describing. Together they close them.
That said — I'd genuinely welcome your findings. Red-teaming is how this gets battle-hardened. You can reach me at [email protected] or check the SDK at github.com/razashariff/agentsign-sdk.

AutoGPT (182K stars) -- no identity LangChain (100K+) -- no identity MCP ecosystem (80K+ stars) -- no identity (a scan of 2,000 MCP servers found ALL lacking authentication) OpenHands (64K) -- no identity AutoGen (50K) -- no identity (Entra ID for users, not agents) CrewAI (45K) -- RBAC for configs, not agents smolagents (25K) -- sandboxing only OpenAI Agents SDK (19K) -- "does not natively provide security" NeMo Guardrails (5.7K) -- content safety only, not identity
AWS Bedrock and Google Vertex have the most mature security -- but it's IAM-based and cloud-locked. No portable agent identity.
That's 600K+ GitHub stars of agent frameworks where agents have zero cryptographic identity. Okta found 91% of orgs use agents but less than 10% have a strategy to secure them.
AgentSign fills this specific gap: not what agents can do (guardrails handle that), but who agents are + what they did + cryptographic proof.
On your points about env injection and lazy-loaded modules bypassing on-disk hash: you're right that static file hashing alone doesn't cover runtime context manipulation. Our attestation checks the registered code artifact, but a production deployment would need runtime sandboxing (process isolation, restricted imports) as a complementary layer. AgentSign handles identity and trust -- sandboxing is the execution environment's job.
On trust score elevation attacks (benign buildup, then exploit): the trust score factors in execution verification rate and success rate continuously, not just cumulatively. A sudden behavioral shift (failed attestations, anomalous outputs) drops the score dynamically. But you're right that a slow, careful escalation is the harder case. That's where the MCP gate's per-request verification adds defense in depth -- even a high-trust agent gets checked every single call.
