AI agents call get_symbol_detail to retrieve information from Codetex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_symbol_detail retrieves and queries pre-indexed symbol information from the code context hierarchy (Tier 3 details). This is a read-only operation analogous to 'get' or 'fetch'—it accesses stored code metadata without creating, modifying, executing, or deleting anything. The worst-case misuse is an AI agent retrieving excessive symbol details, which has minimal blast radius.
From the tool's definition Tool returns detail ('Return the Tier 3 detail') for a specific symbol without modifying data. Name and description indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Return the Tier 3 detail for a specific symbol. It is categorised as a Read tool in the Codetex MCP Server, which means it retrieves data without modifying state.
Register the Codetex MCP server in PolicyLayer and add a rule for get_symbol_detail: 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 Codetex. Nothing to install.
get_symbol_detail 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_symbol_detail 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_symbol_detail. 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_symbol_detail is provided by the Codetex MCP server (mrosata/codetex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
