AI agents call codegraph_get_symbol_info to retrieve information from Codegraph without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though codegraph_get_symbol_info only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access codegraph_get_symbol_info gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Gets quick metadata about any symbol (function, class, variable, type). USE WHEN: you need to quickly understand what a symbol is, check its signature, or see usage count. FASTER than codegraph_get_ai_context when you only need basic info. Returns: name, kind, signature, visibility, file path, line range, and properties (is_async, is_static, etc.). Set includeReferences=true to also get all reference locations (slower). Requires uri and line parameters.. It is categorised as a Read tool in the Codegraph MCP Server, which means it retrieves data without modifying state.
Register the Codegraph MCP server in PolicyLayer and add a rule for codegraph_get_symbol_info: 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 Codegraph. Nothing to install.
codegraph_get_symbol_info 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 codegraph_get_symbol_info 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 codegraph_get_symbol_info. 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.
codegraph_get_symbol_info is provided by the Codegraph MCP server (codegraph-ai/CodeGraph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
