## What it does

The server exposes remote databases to MCP clients via Streamable HTTP at `https://freebase.cloud/api/mcp/{token}`. It links with fifteen engines, covering relational systems like PostgreSQL, key-value stores like Redis, and analytics platforms like ClickHouse. Each connection provides four instruments: native dialect reads (`db_query`), writes (`db_store`), container inspection (`db_list_tables`), and schema descriptions (`db_annotate_table`). PostgreSQL and SQLite include extra helpers such as `pg_dump` and `sqlite_version`.

Security requires caution because your URL path contains the secret token. Committing your configuration file exposes database credentials directly. Before setting up your client, sign up on the freebase.cloud dashboard to generate a connection token. Using the table annotation tool prevents query errors, as language models struggle with status integers or soft delete filters without explicit documentation.

## When to use it
- run queries across 15 databases using their native dialects
- insert and update rows or documents during agent sessions
- document column definitions and schema rules for the assistant
- inspect remote tables, keyspaces, and indices inside the workspace

## Example prompts
- Inspect all collections in the database using `db_list_tables`
- Execute a Cypher query in Neo4j with `db_query` to find connected nodes
- Save column descriptions for the payments table via `db_annotate_table`
