List all available programming languages and their guideline categories. Returns language names, aliases, and available categories.
AI agents call list_guidelines to retrieve information from Mcp Coding Standards without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata about available guidelines without creating, modifying, or deleting data. It is purely informational retrieval with no blast radius risk if invoked by an AI agent.
From the tool's definition Tool is named 'list_guidelines' and described as returning language names, aliases, and available categories—a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all available programming languages and their guideline categories. Returns language names, aliases, and available categories. It is categorised as a Read tool in the Mcp Coding Standards MCP Server, which means it retrieves data without modifying state.
Register the Mcp Coding Standards MCP server in PolicyLayer and add a rule for list_guidelines: 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 Mcp Coding Standards. Nothing to install.
list_guidelines 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 list_guidelines 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 list_guidelines. 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.
list_guidelines is provided by the Mcp Coding Standards MCP server (karatejb/mcp-coding-standards). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
