## Which one, for what

### Postgres MCP Pro (F)

Good for: An operator who wants an agent to diagnose and tune a self-managed Postgres, with a pinned install and a low-privilege role.

Ahead on:
- Agent ergonomics, 57 against 39

Also in its favour:
- No key needed to call it

Watch for: No release since 0.3.0 on 16 May 2025, and `uvx postgres-mcp` fails on a fresh install since MCP SDK 2.0

### Redis MCP (C)

Good for: Teams with a Redis database that want an agent to read and write keys, streams, JSON documents and vector indexes on a developer's machine.

Ahead on:
- Reliability, 62 against 41
- Schema & documentation, 64 against 56
- Security & auth, 54 against 26
- Maintenance & community, 57 against 8
- Transparency & trust, 76 against 61

Watch for: 53 tools load at once, with no toolsets and no read-only subset. Pull request #161 for a tool allowlist has been open since 28 July 2026

## Verdicts

**Postgres MCP Pro.** Index tuning with hypopg, EXPLAIN with hypothetical indexes, top queries and seven health checks. No release since 0.3.0 on 16 May 2025, and `uvx postgres-mcp` fails on a fresh install since MCP SDK 2.0.

**Redis MCP.** Redis's server, under the MIT licence, maps 53 tools onto Redis commands, with typed inputs and a nightly CI run that passed on 9 October 2026. It has no read-only mode, no tool annotations and no changelog file, release 0.5.1 changed the `unsubscribe` input without a note, and PyPI installs failed to start from 28 July to 5 August 2026.

## Before you call either

### Postgres MCP Pro

1. Launch with `uvx --with 'mcp<2' postgres-mcp`. Plain `uvx postgres-mcp` now fails with "No module named 'mcp.server.fastmcp'"
2. Pass `--access-mode=restricted` explicitly. The default is unrestricted
3. Connect with a role that lacks superuser and pg_read_server_files. Restricted mode alone doesn't stop server file reads
4. Put `LIMIT` in every `execute_sql` query. The server returns every row
5. Don't set `analyze: true` on `explain_query` for writes in unrestricted mode. It runs the statement

### Redis MCP

1. Pass the connection with `--url` or explicit flags. The `redis-mcp-server` command overrides `REDIS_HOST`, `REDIS_PORT`, `REDIS_DB`, `REDIS_SSL` and `REDIS_CLUSTER_MODE` with its own defaults when flags are absent
2. Use `scan_keys` with the returned cursor until it is 0. `scan_all_keys`, `hgetall`, `smembers` and `json_get` return everything they match with no limit
3. Read failures from the text. Tools return strings such as `Error ...` or an `error` key in place of an MCP error result
4. Keep the `subscription_id` from `subscribe` or `psubscribe` and pass it to `read_messages` and `unsubscribe`. Idle subscriptions close after 300 seconds
5. Connect as a Redis ACL user limited to the keys and command categories needed, since the server has no read-only switch and `delete` runs without confirmation
