Reads and concatenates ALL 17 global rule files into one response. Use this to load your complete global ruleset into context at once. For a single rule, use rules_get_global_rule instead. Returns: All 17 rules concatenated with section headers.
AI agents call rules_get_global to retrieve information from Claude Rules 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 aggregates existing rule documentation without modifying, executing, or deleting any data. It has no side effects beyond returning information. The low severity reflects that exposing rule definitions to an AI agent carries minimal risk—rules are typically read-only reference material meant to be consulted.
From the tool's definition Tool name contains 'get' and description states 'Reads and concatenates ALL 17 global rule files into one response.' The verb 'reads' and action of retrieving rule content with no modification capability confirm this is a retrieval operation.

Reads and concatenates ALL 17 global rule files into one response. Use this to load your complete global ruleset into context at once. For a single rule, use rules_get_global_rule instead. Returns: All 17 rules concatenated with section headers. It is categorised as a Read tool in the Claude Rules MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Claude Rules MCP Server MCP server in PolicyLayer and add a rule for rules_get_global: 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 Claude Rules MCP Server. Nothing to install.
rules_get_global 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 rules_get_global 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 rules_get_global. 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.
rules_get_global is provided by the Claude Rules MCP Server MCP server (jeremykenedy/claude-rules-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
