Get code examples for a specific topic.
AI agents call get_examples_tool to retrieve information from Best Practices MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that returns informational content (code examples). There is no side effect, no code execution, no data modification, and no destructive capability. The tool simply fetches and displays existing example content based on topic selection. Severity is low because misuse would only result in accessing information already intended to be public/available.
From the tool's definition Tool retrieves code examples for a specific topic with no mutation capability. Described as 'Get code examples' which is a retrieval/query operation. No creation, modification, deletion, execution, or financial impact is possible.
Attacks that exploit this kind of access
Get code examples for a specific topic. It is categorised as a Read tool in the Best Practices MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Best Practices MCP Server MCP server in PolicyLayer and add a rule for get_examples_tool: 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 Best Practices MCP Server. Nothing to install.
get_examples_tool 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_examples_tool 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_examples_tool. 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_examples_tool is provided by the Best Practices MCP Server MCP server (n-ochs/best-practice-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
