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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
