AI agents call get-document-blueprint 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 an existing document blueprint using an identifier as input. Retrieval operations that do not modify data, trigger external actions, or affect system state are classified as Read. The low severity reflects minimal risk if misused by an AI agent, as it only exposes existing data without the ability to alter, delete, or execute operations.
From the tool's definition Tool name is 'get-document-blueprint' and description states 'Gets a document blueprint by Id' — both indicate a retrieval/query operation with no modification or side effects.
Attacks that exploit this kind of access
Gets a document blueprint by Id. 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-document-blueprint: 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-document-blueprint 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-document-blueprint 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-document-blueprint. 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-document-blueprint 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.
