Get rules for a project with optional filtering by area, tags, or severity
AI agents call get_rules to retrieve information from RulesetMCP 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 existing project rules from the ruleset system. It performs no writes, deletions, code execution, or financial operations. The optional filtering suggests parameterized queries rather than state-changing actions.
From the tool's definition Tool name 'get_rules' and description 'Get rules for a project with optional filtering' indicate data retrieval with no side effects. The filtering parameters (area, tags, severity) are query options, not modifications.
Attacks that exploit this kind of access
Get rules for a project with optional filtering by area, tags, or severity. It is categorised as a Read tool in the RulesetMCP MCP Server, which means it retrieves data without modifying state.
Register the Ruleset MCP server in PolicyLayer and add a rule for get_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 RulesetMCP. Nothing to install.
get_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 get_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 get_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.
get_rules is provided by the Ruleset MCP server (n8daniels/rulesetmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
