add_session_memory · Livepilot MCP: Risk & Policy

WHAT IT DOES

What add_session_memory does on Livepilot

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

WHY IT NEEDS A POLICY

Why add_session_memory needs a policy

An AI agent can call add_session_memory faster than any human can review — one bad instruction and it creates or modifies resources in Livepilot by the hundred, each call as confident as the last.

Verdict

add_session_memory Rate-limited

add_session_memory 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 add_session_memory

What does the add_session_memory tool do? +

Add an ephemeral session memory entry. It is categorised as a Write tool in the Livepilot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_session_memory? +

Register the Livepilot MCP server in PolicyLayer and add a rule for add_session_memory: 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 Livepilot. Nothing to install.

What risk level is add_session_memory? +

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

Can I rate-limit add_session_memory? +

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

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