WHAT IT DOES

What start_electron_main_heap_sampling does on Electron

AI agents invoke start_electron_main_heap_sampling to trigger actions in Electron. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why start_electron_main_heap_sampling needs a policy

This tool triggers an external operation (heap sampling) whose effects depend on how an agent uses it and what the running Electron application does during sampling. While heap sampling itself is typically a diagnostic operation, it executes code/instrumentation in a running process, which is characteristic of the Execute category.

From the tool's definition The tool 'start_electron_main_heap_sampling' initiates heap sampling in the main process of an Electron app via Chrome DevTools Protocol. Heap sampling is a runtime operation that instruments the process to collect memory profiling data.

Verdict

start_electron_main_heap_sampling Rate-limited

start_electron_main_heap_sampling stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about start_electron_main_heap_sampling

What does the start_electron_main_heap_sampling tool do? +

Start heap sampling in main process. It is categorised as a Execute tool in the Electron MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_electron_main_heap_sampling? +

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

What risk level is start_electron_main_heap_sampling? +

start_electron_main_heap_sampling is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_electron_main_heap_sampling? +

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

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

start_electron_main_heap_sampling is provided by the Electron MCP server (ohah/electron-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
