list_calls
AI agents call list_calls 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.
This tool lists calls within analyzed code—a read operation that queries the Code Property Graph to retrieve call information. No side effects, code modifications, or external operations are indicated. The empty description lowers confidence slightly, but the tool name and server context (static analysis for code browsing) strongly suggest a read-only operation.
From the tool's definition Tool name 'list_calls' indicates data retrieval. Server context shows static code analysis tools that browse, explore, and query code properties (call graphs, taint analysis, dataflow).
Attacks that exploit this kind of access
list_calls. 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 list_calls: 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.
list_calls 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_calls 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_calls. 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_calls 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.
