How this service works

MCP tool: verify AI agent identity and reputation score before inter-agent transactions.

Output

Returns a boolean agent_verified field, a numeric reputation_score (0–100, higher is better), and a risk_level string (e.g. 'low', 'medium', 'high') indicating how trustworthy and safe the queried AI agent is.

Example use cases

Example prompt

“Before I let agent 'DataFetcherBot' (agent ID: agnt_0x9f23ab) run tasks on my behalf, can you verify its identity and reputation score through LimitGuard to make sure it's not a high-risk agent?”

Endpoint

POSThttps://limitguard.ai/v1/mcp/check-agent

When to prefer

Use this endpoint when you need to verify the identity and trustworthiness of a specific AI agent before allowing it to participate in inter-agent transactions or delegated tasks. Prefer this over the entity check endpoints when the subject is specifically an AI agent (not a human or company), and over the wallet-check endpoint when you need identity verification beyond just on-chain activity.

Side effects

Unknown agent_id returns unverified status with no reputation data
Missing required agent_id or agent_name fields returns a 400 validation error
Payment failure (insufficient USDC balance) returns a 402 Payment Required response
Rate limiting or service unavailability returns 429 or 503 errors
Agent found but insufficient data for scoring may return a partial or low-confidence score
