Db Access MCP vs Universal Db MCP
A side-by-side look at the Db Access MCP and Universal Db MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Db Access MCP for databases work as a local process; choose Universal Db MCP for databases as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Db Access MCP when
- You need dedicated capabilities in the Databases domain.
- You prefer a local stdio subprocess transport.
- You want tools like
dialect_list, connection_list, connection_find.
Choose Universal Db MCP when
- You need dedicated capabilities in the Databases domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
POSTGRES_URI, SQLITE_PATH, MYSQL_URI, DUCKDB_PATH, ALLOW_DESTRUCTIVE, MAX_RESULT_ROWS, QUERY_TIMEOUT, RATE_LIMIT_RPM. - You want tools like
query, schema, explain.

Tools & capabilities
Db Access MCP tools 11
dialect_listLists the supported database dialects: name (the `type` value for connections), default port and the plan format `query_plan` produces.connection_listLists configured connections: key, type, description, `read_only`, host/port/database, tunnel name, metadata. Credentials are **never** returned (allowlist-based sanitization; connection strings are parsed only for host/port/database).connection_findFinds connections by `host`, `port`, `database`, `type`, `read_only` and/or `metadata` key-value pairs. All filters are combined with **AND**. `user`/`password` filters are ignored (and noted in the response).connection_testEnd-to-end health check: secrets → tunnel → pool → one-row server-info query. Returns `ok: true` with server version/user/database/latency, or `ok: false` with the failure code and hint (an unreachable DB is a valid result, not a tool error).queryExecutes SQL on a connection. Accepts `connection`, `query`, optional `database` (see multi-database connections), `max_rows` and `timeout_ms` overrides. Results are truncated to the row cap with `truncated: true`.query_to_fileExecutes a query and writes the result to a file (`csv`/`jsonl`, inferred from the extension) instead of the model context. `file_path` is relative to the export dir (default `/tmp/db-access-mcp/exports`, created on demand), or an absolute/`~` path **under** the export dir or a configured `allow_ex…query_planReturns the execution plan without running the query: `EXPLAIN (FORMAT JSON)` for postgres, `EXPLAIN FORMAT=JSON` for mysql, text `EXPLAIN` for redshift, `SHOWPLAN_XML` for mssql.up_tunnelOpens (or reuses) the tunnel configured for a connection and returns `{host, port, tunnel_id, reused}`. Optional `local_port` binds an exact local port; if the tunnel is already open on a different port or the port is taken, the call fails with the current port in the error.down_tunnelCloses a tunnel by `tunnel_id`. By default only the up_tunnel pin is released — if query pools still hold the tunnel it stays open (`remaining_holders`); `force: true` drains the holder pools and closes it unconditionally.tunnel_listLists the tunnels currently open in this MCP instance with a live health probe: `tunnel_id`, tunnel name/type, local and remote endpoints, `healthy`, holder pools (`connections`), up_tunnel `pins`, external PIDs.config_reloadRe-reads the config files into the running server so connections/tunnels added or edited on disk become usable without a restart. **Never disturbs live state** — see below.

queryExecute a SQL query against the database. Supports parameterized queries for injection safety. In read-only mode, destructive operations (INSERT, UPDATE, DELETE, DROP, etc.) are blocked.schemaGet database schema information: tables, columns, types, and constraints.explainGet query execution plan without running the query.healthCheck database connection health and get server version info.query_historyGet recent query execution history (most recent first).snapshot_schemaTake a snapshot of the current database schema for later drift detection.schema_diffCompare the current schema against the last snapshot taken with snapshot_schema.list_databasesList all configured databases and their connection status. Returns: JSON with list of databases including key, type, database name, and connection status.

Frequently asked questions
Db Access MCP is categorized under Databases and uses a local stdio subprocess. Universal Db MCP belongs to Databases and uses a local stdio subprocess. Pick Db Access MCP for databases work and Universal Db MCP for databases.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Db Access MCP has no declared pricing — check the project's own site. Universal Db MCP has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add rheopyrin-db-access-mcp and universal-db-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
