AI agents call symbols to retrieve information from TempoGraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to query or extract symbol information from a code repository. Without explicit description stating it modifies, deletes, or executes code, it should be classified as a Read operation.
From the tool's definition Tool name 'symbols' with no description provided. Based on naming convention and context within a code graph engine, 'symbols' typically retrieves code symbols (functions, classes, variables) from source files without modifying them.
Attacks that exploit this kind of access
symbols. It is categorised as a Read tool in the TempoGraph MCP Server, which means it retrieves data without modifying state.
Register the TempoGraph MCP server in PolicyLayer and add a rule for 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 TempoGraph. Nothing to install.
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 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 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.
symbols is provided by the TempoGraph MCP server (tempograph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
