Get the complete code of the method containing the error line from the stack trace.
AI agents call get_method_code to retrieve information from Error Tracker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves source code information for diagnostic purposes. It queries existing code without creating, modifying, deleting, or executing anything. The read of potentially sensitive source code is a minor concern but does not elevate the risk category—Read tools are standard in development and debugging workflows.
From the tool's definition Tool description states 'Get the complete code of the method' — a retrieval operation with no modification or side effects. The verb 'Get' and context of querying method source code from a stack trace indicate read-only functionality.
Attacks that exploit this kind of access
Get the complete code of the method containing the error line from the stack trace. It is categorised as a Read tool in the Error Tracker MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Error Tracker MCP Server MCP server in PolicyLayer and add a rule for get_method_code: 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 Error Tracker MCP Server. Nothing to install.
get_method_code 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_method_code 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_method_code. 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_method_code is provided by the Error Tracker MCP Server MCP server (wyccome/mcp-error-tracing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
