Analyze variable data dependencies in backward or forward direction.
AI agents call get_variable_flow 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 performs static analysis by tracing variable dependencies in code without executing it, modifying it, or deleting it. It retrieves and analyzes information about dataflow, which is a read operation. The static analysis context (via Joern's Code Property Graph) means it operates on code representations, not live systems. Blast radius is minimal as it only returns analysis results.
From the tool's definition Tool name 'get_variable_flow' and description 'Analyze variable data dependencies' indicates data retrieval and analysis. The verb 'analyze' and 'get' are read operations. No modification, deletion, or execution of external code is mentioned.
Attacks that exploit this kind of access
Analyze variable data dependencies in backward or forward direction. 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 get_variable_flow: 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.
get_variable_flow 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_variable_flow 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_variable_flow. 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_variable_flow 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.
