 # anvillm-mcp
 
-MCP (Model Context Protocol) server providing sandboxed code execution for LLM agents.
+MCP server providing sandboxed code execution for LLM agents.
 
 ## Overview
 
-anvilmcp bridges MCP clients (Claude Desktop, Kiro, etc.) to shell execution with security isolation. It wraps script execution in a sandbox (landlock/landrun/bwrap) to limit filesystem and network access.

+The `execute_code` tool implementation lives in [ollie](https://github.com/lneely/ollie)'s `exec` package. anvillm-mcp imports it directly, so the two share the same sandboxed execution engine. ollie uses the same package as a built-in tool and does not need anvillm-mcp for `execute_code` — this server exists for MCP clients that lack a built-in equivalent.
