AI agents call main to retrieve information from CodeBadger without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The CodeBadger server is a static code analysis tool using Joern. All sibling tools are query/analysis functions that read code properties and perform security checks without modifying anything. The 'main' tool, despite having an empty description, most likely serves as an entry point for read-only code analysis queries. No evidence suggests code execution, modification, or deletion capabilities.
From the tool's definition Tool name is 'main' with empty description. Based on sibling tools (find_taint_sources, find_taint_sinks, get_backend_status, etc.) and server description emphasizing 'code browsing, security taint analysis, call graph exploration, and dataflow tracking…
Attacks that exploit this kind of access
main. It is categorised as a Read tool in the CodeBadger MCP Server, which means it retrieves data without modifying state.
Register the CodeBadger MCP server in PolicyLayer and add a rule for main: 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 CodeBadger. Nothing to install.
main 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 main 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 main. 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.
main is provided by the CodeBadger MCP server (lekssays/codebadger). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
