Get the default space DUID
AI agents call get_default_space to retrieve information from Dart 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 (a space identifier) from the workspace without modifying, executing, or deleting anything. It is a simple getter that returns information about the default space configuration. No data is created, modified, or destroyed. The low severity reflects minimal risk if misused — an AI agent could only learn about existing workspace structure.
From the tool's definition Tool name and description indicate a retrieval operation: 'Get the default space DUID' — queries and returns an identifier with no side effects.
Attacks that exploit this kind of access
Get the default space DUID. It is categorised as a Read tool in the Dart MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Dart MCP Server MCP server in PolicyLayer and add a rule for get_default_space: 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 Dart MCP Server. Nothing to install.
get_default_space 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_default_space 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_default_space. 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_default_space is provided by the Dart MCP Server MCP server (jmanhype/dart-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
