Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable chemdraw_connector/bridge/_stoichiometry.py:510, chemdraw_connector/snapshots.py:45, tools/office_embed.py:150

            new_path = os.path.join(
                WRITE_DIR, f"{base}-stoich-{stamp}-{unique}.cdxml")

Runs an external command chemdraw_connector/domain/naming.py:118

    result = subprocess.run([str(JRE_BIN), "-version"], capture_output=True, text=True)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
