Structural PHP code search using tree-sitter AST queries. Unlike magento_grep (text-based), this understands PHP AST — matches code structure regardless of variable names, ignores comments/strings. Available named patterns:
AI agents call magento_ast_search to retrieve information from Magector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and indexes existing code without creating, modifying, deleting, or executing anything. It is purely analytical — a semantic query mechanism over a codebase. It cannot change files, run code, or trigger side effects. The lowest-risk Read category applies.
From the tool's definition Tool performs 'Structural PHP code search' and 'matches code structure' through AST queries — fundamentally a retrieval operation with no modification capability.
Attacks that exploit this kind of access
Structural PHP code search using tree-sitter AST queries. Unlike magento_grep (text-based), this understands PHP AST — matches code structure regardless of variable names, ignores comments/strings. Available named patterns:. It is categorised as a Read tool in the Magector MCP Server, which means it retrieves data without modifying state.
Register the Magector MCP server in PolicyLayer and add a rule for magento_ast_search: 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 Magector. Nothing to install.
magento_ast_search 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 magento_ast_search 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 magento_ast_search. 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.
magento_ast_search is provided by the Magector MCP server (magector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
