WHAT IT DOES

What secret_set does on LocalAnt

AI agents use secret_set to create or update resources in LocalAnt, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LocalAnt environment.

RISK

Why secret_set is rated Medium

This tool creates or modifies stored secrets, which is a reversible write operation. While secrets are encrypted, an AI agent could be tricked into storing sensitive credentials (API keys, passwords) that it shouldn't persist, or overwriting legitimate secrets.

From the tool's definition Tool name 'secret_set' and description 'Store a secret by name. The value is encrypted and never returned by any tool' indicate a create/modify operation that writes encrypted data to storage.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs secret_set safely

PolicyLayer is an MCP gateway: it sits between your AI agents and LocalAnt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For secret_set, this is the rule to start with:

secret_set Rate-limited

secret_set stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on secret_set? +

Register the LocalAnt MCP server in PolicyLayer and add a rule for secret_set: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches LocalAnt. Nothing to install.

What risk level is secret_set? +

secret_set is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit secret_set? +

Yes. Add a rate_limit block to the secret_set 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.

How do I block secret_set completely? +
