 Notes:
-- EFS (fs) and EVS (evs) modules are optional. They are loaded only if your profile enables tools with prefixes `fs_*` or `evs_*`. Missing dependencies result in a warning; the rest of the server continues to operate.
+- EFS (fs) and tdvs (tdvs) modules are optional. They are loaded only if your profile enables tools with prefixes `fs_*` or `tdvs_*`. Missing dependencies result in a warning; the rest of the server continues to operate.
 - Logging writes to a per‑user file location by default for HTTP/SSE transports; console logging is disabled for stdio to avoid polluting MCP protocol streams. Override with `LOG_DIR` or `NO_FILE_LOGS=1`.
     - Handles errors and response formatting
     - Reconnects when needed
