Comparison

Oracle Database vs PostgreSQL

Oracle Database is an MCP server published by git-scarrow. Marketplaces we read that list it: 1 (Docker MCP Catalog). PostgreSQL is an MCP server published by antonorlov. Marketplaces we read that list it: 1 (Official MCP Registry). As of our marketplace pass on 2026-10-14. This pair was picked by a reader, not by our comparison rule, so search engines are asked not to index the page.

Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

What each says it does

Oracle Database

In its own words, on Docker MCP Catalog:

Connect to Oracle databases via MCP, providing secure read-only access with support for schema exploration, query execution, and metadata inspection.

PostgreSQL

In its own words, on Official MCP Registry:

MCP server for PostgreSQL: local, Docker, RDS, Neon, Supabase, or behind an SSH bastion.

How to run each

Oracle Database As a local MCP server: Docker image

Claude Code

claude mcp add --env "ORACLE_PASSWORD=<YOUR_ORACLE_PASSWORD>" --transport stdio oracle -- docker run -i --rm -e ORACLE_PASSWORD mcp/oracle

Requires: ORACLE_PASSWORD (secret)

PostgreSQL As a local MCP server: npm package

Claude Code

claude mcp add --env "DATABASE_URL=<YOUR_DATABASE_URL>" --env "PG_PASSWORD=<YOUR_PG_PASSWORD>" --env "PG_SSH_PASSPHRASE=<YOUR_PG_SSH_PASSPHRASE>" --env "PG_SSH_PASSWORD=<YOUR_PG_SSH_PASSWORD>" --transport stdio mcp-postgres-server -- npx -y mcp-postgres-server

Requires: DATABASE_URL (secret), PG_PASSWORD (secret), PG_SSH_PASSPHRASE (secret), PG_SSH_PASSWORD (secret)

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Tools each declares

The marketplaces of PostgreSQL publish no list of tools, so we do not compare tools.

Settings each asks for

Only Oracle Database asks for

ORACLE_CONNECTION_STRING
ORACLE_PASSWORD (secret)
ORACLE_USER

Only PostgreSQL asks for

DATABASE_URL (secret)
PG_ALLOW_WRITE
PG_CONNECT_TIMEOUT
PG_DATABASE
PG_ENABLE_RUNTIME_CONNECT
PG_HOST
PG_MAX_RESULT_BYTES
PG_PASSWORD (secret)
PG_PORT
PG_SSH_AGENT
PG_SSH_FINGERPRINT
PG_SSH_HOST

Show the remaining 10

PG_SSH_KEEPALIVE_INTERVAL
PG_SSH_PASSPHRASE (secret)
PG_SSH_PASSWORD (secret)
PG_SSH_PORT
PG_SSH_PRIVATE_KEY
PG_SSH_USER
PG_SSLMODE
PG_SSL_CA
PG_STATEMENT_TIMEOUT
PG_USER

Settings as each marketplace publishes them. Asking for fewer is not better in itself.
