Retrieves the OData $metadata document for the service.
AI agents call getODataMetadata to retrieve information from Dynamics 365 Finance & Operations 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 schema/metadata information about available OData resources. Retrieving metadata is a read-only operation with no side effects—it does not create, modify, delete, or execute code. The metadata document itself is part of the OData service contract and is typically intended for client discovery.
From the tool's definition Tool name 'getODataMetadata' and description 'Retrieves the OData $metadata document for the service' indicate a read-only operation that queries service metadata without modification, creation, deletion, or execution of arbitrary commands.

Register the Dynamics 365 Finance & Operations MCP Server MCP server in PolicyLayer and add a rule for getODataMetadata: 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 Dynamics 365 Finance & Operations MCP Server. Nothing to install.
getODataMetadata 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 getODataMetadata 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 getODataMetadata. 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.
getODataMetadata is provided by the Dynamics 365 Finance & Operations MCP Server MCP server (sahib-sawhney-wh/fno-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
