Loads a memory heapsnapshot and returns snapshot summary stats.
AI agents call load_memory_snapshot to retrieve information from Chrome Devtools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes memory snapshot data from a Chrome browser session. It does not create, modify, delete, execute code, or trigger external side effects—it only reads and summarizes existing memory information. This is a classic Read operation with low severity since misuse would only expose memory statistics without operational consequences.
From the tool's definition Tool name 'load_memory_snapshot' and description 'Loads a memory heapsnapshot and returns snapshot summary stats' indicate retrieval and analysis of existing data without modification. The use of 'loads' and 'returns' confirms a read-only operation.
Attacks that exploit this kind of access
Loads a memory heapsnapshot and returns snapshot summary stats. It is categorised as a Read tool in the Chrome Devtools MCP Server, which means it retrieves data without modifying state.
Register the Chrome Devtools MCP server in PolicyLayer and add a rule for load_memory_snapshot: 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 Chrome Devtools. Nothing to install.
load_memory_snapshot 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 load_memory_snapshot 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 load_memory_snapshot. 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.
load_memory_snapshot is provided by the Chrome Devtools MCP server (shivamprasad99/chrome-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
