FAQ

Elasticsearch vs Postgres MCP Pro: which MCP server should I use?

Pick Elasticsearch when query dsl drafting. Pick Postgres MCP Pro when query performance tuning. Elasticsearch is built for search elasticsearch, while Postgres MCP Pro focuses on tune & inspect postgres.

Can I run both Elasticsearch and Postgres MCP Pro together?

Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
