AI agents call list_restraints to retrieve information from Molmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the naming convention and the context of a code discovery engine, 'list_restraints' most likely retrieves or enumerates existing constraints, restrictions, or limitations in the codebase without modifying them. The 'list_' prefix strongly suggests a Read operation with no side effects.
From the tool's definition Tool name 'list_restraints' indicates a query/retrieval operation that lists existing restraints or constraints. The tool name follows a 'list_*' pattern consistent with the Read category tools (list, get, fetch).
Attacks that exploit this kind of access
list_restraints. It is categorised as a Read tool in the Molmcp MCP Server, which means it retrieves data without modifying state.
Register the Mol MCP server in PolicyLayer and add a rule for list_restraints: 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 Molmcp. Nothing to install.
list_restraints 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 list_restraints 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 list_restraints. 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.
list_restraints is provided by the Mol MCP server (molcrafts/molmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
