Get Firebase function logs. Returns 20 lines by default - use filters (pattern, level, functionName) to narrow results before increasing limit.
AI agents call get_function_logs to retrieve information from Firebase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing log data from Firebase functions without modifying, deleting, or executing any operations. It is purely informational—filtering and returning logs based on specified criteria. The worst case misuse would be information disclosure of sensitive logs, which is a read-based risk. The Firebase Emulator environment context further limits blast radius.
From the tool's definition Tool description states 'Get Firebase function logs' with filtering options (pattern, level, functionName). The verb 'Get' and the action of retrieving/querying logs indicates no data modification or execution.

Get Firebase function logs. Returns 20 lines by default - use filters (pattern, level, functionName) to narrow results before increasing limit. It is categorised as a Read tool in the Firebase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Firebase MCP Server MCP server in PolicyLayer and add a rule for get_function_logs: 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 Firebase MCP Server. Nothing to install.
get_function_logs 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 get_function_logs 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 get_function_logs. 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.
get_function_logs is provided by the Firebase MCP Server MCP server (nigelthorne/firebase_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
