Get details of a specific role including permissions
AI agents call get_role to retrieve information from BookStack 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 and queries role information without modifying, executing, or deleting any data. It is a read-only operation that returns existing configuration data about roles within the BookStack instance. Even though it exposes permission details, the tool itself performs no mutations or dangerous operations.
From the tool's definition Tool name 'get_role' with description 'Get details of a specific role including permissions' performs a retrieval operation. The verb 'Get' and the informational purpose (returning role details and permissions) indicate a query with no side effects.

Register the BookStack MCP Server MCP server in PolicyLayer and add a rule for get_role: 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 BookStack MCP Server. Nothing to install.
get_role 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_role 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_role. 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_role is provided by the BookStack MCP Server MCP server (lautarobarba/bookstack_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
