Fast text search across the workspace files. Uses ripgrep when available,
AI agents call search_codebase to retrieve information from Debugging MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only searching and querying of codebase files. It retrieves information without modifying, executing, or deleting any code. The server description explicitly mentions 'preventing destructive operations,' and search is a fundamental diagnostic read operation. Low severity because even if misused, search alone cannot harm systems or data.
From the tool's definition Tool name 'search_codebase' and description 'Fast text search across the workspace files' indicate retrieval of data with no side effects.
Attacks that exploit this kind of access
Fast text search across the workspace files. Uses ripgrep when available,. It is categorised as a Read tool in the Debugging MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Debugging MCP Server MCP server in PolicyLayer and add a rule for search_codebase: 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 Debugging MCP Server. Nothing to install.
search_codebase 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 search_codebase 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 search_codebase. 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.
search_codebase is provided by the Debugging MCP Server MCP server (luischang07/debugging-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
