Locate symbol definitions in the workspace by name. This is the normal first step before code.trace_callers or code.trace_flow when the defining file is unknown. Language filters: ${SUPPORTED_LANGUAGE_FILTERS}.
AI agents call code.find_symbol to retrieve information from Navigation Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs code navigation and symbol lookup—a read-only operation that retrieves information about where symbols are defined in a codebase. It does not create, modify, delete, or execute any code. The low severity reflects minimal risk even if misused, as it only returns metadata about code structure without affecting the repository or triggering external operations.
From the tool's definition Tool description states 'Locate symbol definitions in the workspace by name' and is described as 'the normal first step before code.trace_callers or code.trace_flow'.
Attacks that exploit this kind of access
Locate symbol definitions in the workspace by name. This is the normal first step before code.trace_callers or code.trace_flow when the defining file is unknown. Language filters: ${SUPPORTED_LANGUAGE_FILTERS}. It is categorised as a Read tool in the Navigation Agent MCP Server, which means it retrieves data without modifying state.
Register the Navigation Agent MCP server in PolicyLayer and add a rule for code.find_symbol: 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 Navigation Agent. Nothing to install.
code.find_symbol 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 code.find_symbol 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 code.find_symbol. 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.
code.find_symbol is provided by the Navigation Agent MCP server (j0k3r-dev-rgl/navigation-agent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
code.find_symbol is one line of Navigation Agent's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
