Resolve a symbol by fuzzy name
AI agents call graph.resolve_symbol to retrieve information from CodeGraph MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the code graph to find and return symbol information based on a fuzzy name match. It retrieves data without modifying, executing, or deleting anything. Blast radius is minimal as it only reads symbol metadata from the graph.
From the tool's definition "Resolve a symbol by fuzzy name" — performs a lookup/query operation on the code graph
Attacks that exploit this kind of access
Resolve a symbol by fuzzy name. It is categorised as a Read tool in the CodeGraph MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CodeGraph MCP Server MCP server in PolicyLayer and add a rule for graph.resolve_symbol: 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 MCP Server. Nothing to install.
graph.resolve_symbol 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 graph.resolve_symbol 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 graph.resolve_symbol. 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.
graph.resolve_symbol is provided by the CodeGraph MCP Server MCP server (nabiatech/codegraph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
