Hi HN – I built an open-source, self-hosted Model Context Protocol (MCP) server for WhatsApp: https://github.com/lharries/whatsapp-mcp
It connects to your personal WhatsApp account via the WhatsApp Web multi-device API (using whatsmeow from the Beeper team), and doesn't rely on third-party APIs. All messages are stored locally in SQLite. Nothing is sent to the cloud unless you explicitly allow your LLM to access the data via tools – so you maintain full control and privacy.
The MCP server can:
- Search your messages, contacts, and groups
- Send WhatsApp messages to individuals or groups
Why build this?
99% of your life is stored in WhatsApp, by connecting an LLM to WhatsApp you get all this context. And your AI agent can execute tasks on your behalf by sending messages.

Hey HN,
I built pg-mcp, a Model Context Protocol (MCP) server for PostgreSQL that provides structured schema inspection and query execution for LLMs and agents. It's multi-tenant and runs over HTTP/SSE (not stdio)
Features
- Supports multiple database connections from multiple agents
- Schema Introspection: Returns table structures, types, indexes and constraints; enriched with descriptions from pg_catalog. (for well documented databases)
- Read-Only Queries: Controlled execution of queries via MCP.
- EXPLAIN Tool: Helps smart agents optimize queries before execution.
- Extension Plugins: YAML-based plugin system for Postgres extensions (supports pgvector and postgis out of the box).
- Server Mode: Spin up the container and it's ready to accept connections at http://localhost:8000/sse
