AI agents call iam_list_keys to retrieve information from Mimi Seed without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries IAM service account keys without modifying or deleting them. It is fundamentally a Read operation. However, severity is elevated to high because: (1) it exposes sensitive authentication credentials metadata that could inform an attacker about the security posture of the account, (2) the context mentions this data is used to 'find keys to revoke,' indicating keys are security-critical,…
From the tool's definition Tool name: iam_list_keys. Description: 'Lists existing keys for a given service account. Returns keyId / keyType / expiration time. Used when finding keys to revoke.'

iam_list_keys is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the iam_list_keys rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for iam_list_keys. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
iam_list_keys is provided by the Mimi Seed MCP server (@yoonion/mimi-seed-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
iam_list_keys is one line of Mimi Seed's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
