AI comment:
ReferenceError: require is not defined
The project is configured as an ES module ("type": "module"), but mcp.js directly calls CommonJS require("node:path") instead of an ES import statement or createRequire().
Fix src/cli/commands/mcp.ts (or dist/.../mcp.js)
TypeScript
// Replace:
// const logFilePath = require("node:path").resolve(process.cwd(), ".opencode", "opencode-rag.log");
// With:
import path from "node:path";
import os from "node:os";
const baseDir = process.env.OPENCODE_DATA_DIR
|| path.resolve(process.cwd(), ".opencode");
const logFilePath = path.resolve(baseDir, "opencode-rag.log");

Good catch, @skorphil you (and your AI) nailed it!
Your diagnosis was spot on. The fix is in: mcp.ts was using the old CommonJS style (require) in a project that uses the modern ES module style, so it blew up with ReferenceError: require is not defined.
Funny thing is, it was really hard to notice, since I currently don't use the mcp actively:
Every other command (list, show, dump, query) already did it the right way - mcp was the odd one out.
About your suggested fallback (OPENCODE_DATA_DIR / user dirs): I left that part out for now, since every other command writes its log to the same spot (.opencode/opencode-rag.log in the current directory). Adding a fallback in just one place would make things inconsistent. But I'd happily take a PR that changes it everywhere at once - that's the right way to do it.
I'll ships in the next patch release (2.0.1) now.
Thanks again for the report!
