AI agents call get-references-data-type to retrieve information from Mcp Dev 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 information about which document types and properties reference a data type. It has no side effects—it performs a lookup operation only. While the usage examples mention 'before modifying or deleting it', the tool itself only reads/retrieves data. The highest severity action mentioned is informational (identify before action), not the action itself.
From the tool's definition Tool name includes 'get-references' and description states it 'Gets the document types and properties that use a specific data type' with no mention of modifying or deleting data. It 'Returns a detailed list' of references.

Gets the document types and properties that use a specific data type. This is the recommended method to find all document types that reference a particular data type. Usage examples: - Find all document types using the RichText editor data type - Identify properties that reference a specific data type before modifying or deleting it - Perform bulk updates to all properties using a specific data type Returns a detailed list with content type information (id, type, name, icon) and all properties (name, alias) that use the specified data type. It is categorised as a Read tool in the Mcp Dev MCP Server, which means it retrieves data without modifying state.
Register the Mcp Dev MCP server in PolicyLayer and add a rule for get-references-data-type: 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 Mcp Dev. Nothing to install.
get-references-data-type 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-references-data-type 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-references-data-type. 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-references-data-type is provided by the Mcp Dev MCP server (@umbraco-cms/mcp-dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
