Get all symbols in a file or directory.
AI agents call get_symbols to retrieve information from Code Intelligence MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static code analysis to extract symbol metadata (functions, classes, variables, etc.) from source code. It is a pure read operation that queries code structure without creating, modifying, deleting, or executing anything. Symbol retrieval is a foundational capability for code intelligence and exploration, with minimal blast radius if misused—at worst it returns information about the codebase.
From the tool's definition Tool name is 'get_symbols' and description states it retrieves/queries 'all symbols in a file or directory'.
Attacks that exploit this kind of access
Get all symbols in a file or directory. It is categorised as a Read tool in the Code Intelligence MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code Intelligence MCP Server MCP server in PolicyLayer and add a rule for get_symbols: 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 Code Intelligence MCP Server. Nothing to install.
get_symbols 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_symbols 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_symbols. 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_symbols is provided by the Code Intelligence MCP Server MCP server (tech-spoke/llm-helper). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
