Search logs by message content or pattern. Useful for finding specific events or tracking particular operations.
AI agents call search_logs_by_message to retrieve information from GCP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries Cloud Logging to retrieve log entries matching a message pattern. It has no side effects: it does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal — an agent could search logs it should not access, but this is an access control issue rather than a dangerous capability.
From the tool's definition Tool name and description indicate 'search logs by message content or pattern' and 'finding specific events or tracking particular operations' — these are read-only retrieval operations with no modification, deletion, or execution of external systems.
Attacks that exploit this kind of access
Search logs by message content or pattern. Useful for finding specific events or tracking particular operations. It is categorised as a Read tool in the GCP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GCP MCP Server MCP server in PolicyLayer and add a rule for search_logs_by_message: 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 GCP MCP Server. Nothing to install.
search_logs_by_message 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 search_logs_by_message 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 search_logs_by_message. 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.
search_logs_by_message is provided by the GCP MCP Server MCP server (jayrajgoyal/gcp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
