Low Risk

extract_code_blocks

Extract all code blocks from Markdown. Returns JSON array with language, code content, and start/end line numbers.

Part of the AI Answer Copier MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call extract_code_blocks to retrieve information from AI Answer Copier without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though extract_code_blocks only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.
