pmda-drug-info skill's pmda_server.py imports opensearchpy to query
the OpenSearch pmda_sections index. catalog-agent base image already
ships psycopg (for PG drug_master queries) but was missing
opensearch-py, so the MCP stdio server failed at import time with
ModuleNotFoundError → 0 tools exposed to the bot.
Add opensearch-py >=2.2.0,<3.0.0 to pyproject.toml dependencies and
the matching pinned line (opensearch-py==2.7.1) to requirements.txt.
Verified pmda-drug-info needs:
from opensearchpy import OpenSearch # os_client.py
from opensearchpy.helpers import bulk # ingest path
After this image is rebuilt and deployed to onprem-dev, MCP stdio
servers loaded from skill plugin.json start cleanly and tools/list
returns the 10 tools from pmda_tools.json.
