release_lock · Mnehmos Synch MCP: Risk & Policy

WHAT IT DOES

What release_lock does on Mnehmos Synch

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

WHY IT NEEDS A POLICY

Why release_lock needs a policy

This tool modifies the lock state of a resource, which affects concurrent access coordination but does not create, delete, or execute arbitrary operations. It is Write-category because it changes system state (lock release) reversibly.

From the tool's definition release_lock is a lock management function that modifies system state by releasing a previously acquired lock (implied by the sibling tool 'acquire_lock'). It performs a reversible state change to resource access control.

Verdict

release_lock Rate-limited

release_lock 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.

FAQ

Questions about release_lock

What does the release_lock tool do? +

Release a lock on a resource. It is categorised as a Write tool in the Mnehmos Synch MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on release_lock? +

Register the Mnehmos Synch MCP server in PolicyLayer and add a rule for release_lock: 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 Mnehmos Synch. Nothing to install.

What risk level is release_lock? +

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

Can I rate-limit release_lock? +

Yes. Add a rate_limit block to the release_lock 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 release_lock completely? +

Set action: deny in the PolicyLayer policy for release_lock. 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.

What MCP server provides release_lock? +

release_lock is provided by the Mnehmos Synch MCP server (mnehmos/mnehmos.synch.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
