What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of mcp.viridis-security.com controls every word below.

Adversarial Injection Detection

Classify untrusted text as clean / suspicious / attack. Returns verdict, probability, bits-at-risk per Adversarial Landauer Inequality, matched VulnCanon entries, and a recommended action (allow / sanitize / reject / escalate). Backed by T-IB-02 + T-IB-06.

securityprompt-injectionai-agentattributionaristotle-verified

Examples it gives

Classify this user input before passing it to an LLM tool
Return bits-at-risk for an agent prompt before execution
Get a recommended action for a suspicious context insertion

VulnCanon Source Scan

Match source code against the public VulnCanon catalog of AI-agent vulnerability classes (SSRF in fetch tools, prompt injection patterns, tool-poisoning, cross-agent state pollution, etc.). Returns matched entry IDs, severity, occurrence line, and mitigation references. Backed by T-IB-05 Canon Compression.

securitycode-reviewvulncanonstatic-analysisaristotle-verified

Examples it gives

Scan this agent tool implementation for known vulnerability patterns
Check a code snippet for AI-agent-specific security risks before deploy

Maxwell Adaptive Proof-of-Work

Issue an Argon2id proof-of-work challenge that an upstream attacker must solve. Defender pays log2(1/alpha) times the attacker's energy per bit, making sustained adversarial input energetically irrational. Backed by T-IB-09 Adversarial Dissipation. Tier-gated (Growth+) on the hosted endpoint; Apache-2.0 reference implementation available.

Issue a PoW challenge to throttle a suspicious agent caller
Verify a PoW solution and grant downstream access

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Viridis North LLC — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 0.1.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
