List all symbols defined in a specific file — useful to understand what a file exports or contains without reading raw source.
AI agents call file_symbols to retrieve information from code-intel 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 analysis and information retrieval without modifying, executing, or deleting anything. It returns structured metadata about symbols in a file, similar to a list or search operation. No side effects or external operations are triggered.
From the tool's definition Tool name 'file_symbols' and description states it 'List[s] all symbols defined in a specific file' and is 'useful to understand what a file exports or contains without reading raw source.' This is a read-only operation that queries/retrieves metadata about…

List all symbols defined in a specific file — useful to understand what a file exports or contains without reading raw source. It is categorised as a Read tool in the code-intel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the code-intel MCP Server MCP server in PolicyLayer and add a rule for file_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-intel MCP Server. Nothing to install.
file_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 file_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 file_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.
file_symbols is provided by the code-intel MCP Server MCP server (vohongtho/code-intel-platform). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
