Returns all Cursor rules that apply to the given file paths. Includes rules with alwaysApply:true and auto-attached rules whose globs match at least one file path.
AI agents call cursor_get_applicable_rules to retrieve information from Clodbridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves Cursor configuration rules that apply to specific files. It performs no side effects, creates no data, executes no code, and deletes nothing. The operation is purely informational, matching the Read category profile (search, list, get, fetch). The blast radius if misused is minimal — an agent could learn about project rules but cannot modify them or execute arbitrary operations.
From the tool's definition Tool description states 'Returns all Cursor rules' — it retrieves and queries rules based on file paths with no modification, deletion, or execution. The verb 'Returns' indicates a read-only operation.
Attacks that exploit this kind of access
Returns all Cursor rules that apply to the given file paths. Includes rules with alwaysApply:true and auto-attached rules whose globs match at least one file path. It is categorised as a Read tool in the Clodbridge MCP Server, which means it retrieves data without modifying state.
Register the Clodbridge MCP server in PolicyLayer and add a rule for cursor_get_applicable_rules: 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 Clodbridge. Nothing to install.
cursor_get_applicable_rules 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 cursor_get_applicable_rules 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 cursor_get_applicable_rules. 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.
cursor_get_applicable_rules is provided by the Clodbridge MCP server (rethunk-ai/clodbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
