PostgreSQL vs Tabularis
A side-by-side look at the PostgreSQL and Tabularis MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose PostgreSQL for databases work as a local process; choose Tabularis for databases. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose PostgreSQL when
- You need dedicated capabilities in the Databases domain.
- You prefer a local stdio subprocess transport.
- You want tools like
query, execute, list_schemas.
Choose Tabularis when
- You need dedicated capabilities in the Databases domain.
- Its auth model fits you: No auth required.
- You want tools like
list_connections, list_databases, list_tables.

Tools & capabilities
PostgreSQL tools 5
queryRun one read-only SQL statement against the connected PostgreSQL database and get rows back as JSON. Send exactly one statement per call (SELECT, WITH, EXPLAIN, or SHOW). It runs inside an engine-enforced read-only transaction, so any write is refused by the database. Use this tool for all data reading, aggregation, and query planning. Returns {rows, rowCount, returnedRows, truncated}, plus hint when truncated is true. Prefer $1, $2 placeholders with the params array over interpolating values. Results are capped at ~32768 bytes; truncated:true means rows were dropped - add LIMIT/WHERE or select fewer columns.executeRun a data-modifying SQL statement (INSERT/UPDATE/DELETE or DDL). Currently DISABLED: the server is read-only, so this returns an error and changes nothing. To enable writes, the operator must start the server with PG_ALLOW_WRITE=true.list_schemasList every schema in the connected database. Start here when exploring an unfamiliar database, then call list_tables for the schema you care about. Returns {schemas: [name, ...]}.list_tablesList all tables in a schema (default: 'public'). Use this before querying tables you have not seen yet, then call describe_table for column details. Returns {tables: [name, ...]}.describe_tableShow the structure of one table: column names, data types, nullability, defaults, and primary-key membership. Call this before writing non-trivial queries against a table. Returns {columns: [{column, type, nullable, default, is_primary_key}, ...]}.

Frequently asked questions
PostgreSQL is categorized under Databases and uses a local stdio subprocess. Tabularis belongs to Databases and uses an install path we have not confirmed yet. Pick PostgreSQL for databases work and Tabularis 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. Tabularis has no confirmed install command yet — follow its own setup instructions.
PostgreSQL has no declared pricing — check the project's own site. Tabularis is listed as free. Auth: no auth required. 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 postgresql and tabularis as separate keys in the same mcpServers object, and your assistant will call tools from either one.
