WHAT IT DOES

What set_session_variable does on Logicmonitor

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

RISK

Why set_session_variable is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_session_variable safely

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

set_session_variable Rate-limited

set_session_variable 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Logicmonitor, apply this rule, and every set_session_variable call is checked against it from then on.

FAQ

Questions about set_session_variable

What does the set_session_variable tool do? +

Set a user-defined session variable for use across tool calls. It is categorised as a Write tool in the Logicmonitor MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_session_variable? +

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

What risk level is set_session_variable? +

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

Can I rate-limit set_session_variable? +

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

Set action: deny in the PolicyLayer policy for set_session_variable. 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 set_session_variable? +

set_session_variable is provided by the Logicmonitor MCP server (pypi:lm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
