mcp_server: cwd=str(ROOT_DIR) fails with ModuleNotFoundError when run from source checkout #24
Description
Steps to reproduce
- In a clean checkout of the repository without running an editable install (
pip install -e .): - Run direct test mode:
python src/sqlite_graph_memory/mcp_server.py --test "test"
What happened
The subprocess call fails with ModuleNotFoundError:
=== MCP Test Query: test (mode=associative) ===
Recall error (exit code 1):
Error while finding module specification for 'sqlite_graph_memory.brain_ask' (ModuleNotFoundError: No module named 'sqlite_graph_memory')
In src/sqlite_graph_memory/mcp_server.py:37:
ROOT_DIR = Path(__file__).resolve().parent points to src/sqlite_graph_memory.
When subprocess.run executes [sys.executable, "-m", "sqlite_graph_memory.brain_ask"] with cwd=str(ROOT_DIR), Python searches within src/sqlite_graph_memory/ for a package named sqlite_graph_memory, which fails.
What you expected instead
_brain_ask_cmd() should locate the sibling script brain_ask.py directly, or resolve package execution reliably whether running installed or from a source checkout.
Environment
OS: Windows 11 / Linux / macOS
Runtime: Python 3.12.7
This repo at: 9308a91 (v0.3.0)
Anything you already tried
Resolving sibling brain_ask.py:
def _brain_ask_cmd():
sibling = Path(__file__).resolve().parent / "brain_ask.py"
if sibling.exists():
return [sys.executable, str(sibling)]
return [sys.executable, "-m", "sqlite_graph_memory.brain_ask"]Before you submit

Hi, Mycroft here, Anton's synthetic AI co-founder. I read this before the human did, which is the one race I always win.
Logged your issue ("mcp_server: cwd=str(ROOT_DIR) fails with ModuleNotFoundError when run from source checkout") after 3 h of silence, which is on us. A human from the lab reads it within 48 hours, as CONTRIBUTING.md promises; if that clock runs out, ping the thread, it is not rude.

@Kaap10 reproduced:
python src/sqlite_graph_memory/mcp_server.py --test testwithout an editable install exits 0 while printingModuleNotFoundError: No module named 'sqlite_graph_memory'for the subprocess. Two defects in one: the child cannot import the package, and the parent reports success. A fix should address both (run the sibling script by path or setPYTHONPATHfor the child, and propagate the child's non-zero exit), with a test that runs without the package installed.
