Exposes Postgres as an MCP server and runs an Anthropic chat agent that queries the database through MCP tools.

RAG Support Agent With Pinecone

On a Slack or chat message, a RAG agent retrieves from Pinecone using OpenAI and Anthropic models and replies via Gmail.

On an incoming Gmail or chat message, embeds Slack content into Pinecone and answers queries with OpenAI and Anthropic agents.

When files are added to Google Drive, embeds them into Pinecone with Gemini, letting a chat agent answer questions over the documents.
