Which MCP Server Should You Choose?
Choose MCP Multi Db when:
You need dedicated capabilities in the Databases domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
You have access to required keys: MCP_DB_CONFIG, MCP_DATABASES.
One MCP server for PostgreSQL, MySQL, and SQLite. Unified read-only tools (listdatabases, listtables, describetable, runquery) across all three engines with two-layer read-only enforcement (SQL-text guard + DB-level read-only transactions). Install: npx -y mcp-multi-db.
Read-only MCP server for ClickHouse metadata, parameterized queries, and plan analysis.
MCP Multi Db is categorized under Databases and uses a local stdio subprocess. In contrast, ClickHouse belongs to Databases using local stdio subprocess. Select MCP Multi Db when you need capabilities focused on databases and ClickHouse when you require tools for databases.
Get cluster properties and execution limits. Returns ClickHouse server version plus enforced limits (max rows, timeouts) for the profile.
run_query
Execute read-only SELECT or WITH … SELECT. One statement; DML, DDL, SET, SYSTEM, and similar are rejected. Returns `{data, row_count}` where `data` is an RFC 4180 CSV string. Pass `snapshot=true` to persist the result to disk and receive `{snapshot_uri, row_count}` instead; fetch the CSV via the sn…
run_show
Execute SHOW introspection statement. One statement per call; INTO OUTFILE rejected. Interactive row limits apply (default 500, hard ceiling 1 000). Same timeout as run_query.
analyze_query
Explain read-only SELECT or WITH … SELECT. Returns plan, pipeline, and/or syntax text. Default types plan and pipeline. Uses query timeout and optional database; no max-rows cap unlike run_query.
list_databases
List databases. Rows from system.databases visible to the connection.
list_tables
List tables and views in a database. Rows from system.tables: name, engine, primary_key, sorting_key, partition_key, total_rows, total_bytes for query planning.
list_columns
List columns for a table or view. Rows from system.columns for the resolved database and table.
