AI agents call fm_get_layout_metadata to retrieve information from FileMaker 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 metadata about FileMaker layouts—field definitions, portal information, and value lists. It performs no data modification, deletion, execution of commands, or financial operations. The read-only constraint documented in the server description confirms this is a passive data retrieval operation with minimal risk if misused by an AI agent, as it cannot alter any state.
From the tool's definition Server description states 'read-only access' and tool name 'fm_get_layout_metadata' combined with sibling tools (fm_get_layouts, fm_get_records, fm_get_record_by_id, fm_export_database_metadata) all indicate data retrieval operations.

Register the FileMaker MCP Server MCP server in PolicyLayer and add a rule for fm_get_layout_metadata: 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 FileMaker MCP Server. Nothing to install.
fm_get_layout_metadata 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 fm_get_layout_metadata 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 fm_get_layout_metadata. 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.
fm_get_layout_metadata is provided by the FileMaker MCP Server MCP server (ta-toshio/filemaker-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
