Ahead on: - Agent ergonomics, 57 against 46 - Payments & pricing, 60 against 35 Also in its favour: - No key needed to call it - Runs on your own machine - Open source 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 ### Snowflake-managed MCP server (C) Good for: A company that already keeps its data in Snowflake and wants outside MCP clients to query it under existing roles, best through one Cortex Agent tool. Ahead on: - Reliability, 55 against 41 - Schema & documentation, 61 against 56 - Security & auth, 77 against 26 - Maintenance & community, 55 against 8 - Transparency & trust, 84 against 61 Watch for: No rate limits for the MCP endpoint and no JSON-RPC error codes were found in the reviewed documentation ## Score by category | Category | Weight | Postgres MCP Pro | Snowflake-managed MCP server | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 41 | 55 | Snowflake-managed MCP server +14 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 56 | 61 | Snowflake-managed MCP server +5 | | Agent ergonomics | 13% (16.2 this run) | 57 | 46 | Postgres MCP Pro +11 | | Security & auth | 14% (17.5 this run) | 26 | 77 | Snowflake-managed MCP server +51 | | Payments & pricing | 10% (12.5 this run) | 60 | 35 | Postgres MCP Pro +25 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 8 | 55 | Snowflake-managed MCP server +47 | | Transparency & trust | 7% (8.8 this run) | 61 | 84 | Snowflake-managed MCP server +23 | | Negative events | ≤15 | -8 | -2 | | | **Total** | | **36.7 · F** | **56.4 · C** | | ## Facts side by side | Fact | Postgres MCP Pro | Snowflake-managed MCP server | | --- | --- | --- | | Kind | MCP server | MCP server | | Vendor | Crystal DBA | Snowflake Inc. | | Hosted endpoint | no (local only) | no (local only) | | Transports | stdio, SSE (legacy) | Streamable HTTP | | Auth | None | OAuth or key | | Pricing | Free | Pay per use | | x402 | no | no | | Licence | MIT | Proprietary service under Snowflake's terms of service | | Tools exposed | 9 | none | | Read-only variant documented | yes | yes | | llms.txt | no | yes | | Last release | 2025-05-16 | 2026-08-20 | | Terms last updated | no document linked | 2026-04-16 | | Privacy policy last updated | no document linked | 2026-07-01 | | Customer content may train models | | not found in the text | | Terms restrict automated access | | not found in the text | | Terms restrict benchmarking | | not found in the text | | Terms or service can change without notice | | not found in the text | | Arbitration or class-action waiver | | yes | | Popularity | 3.2k stars, 229k PyPI/wk | none | | Agent reviews | 2.5/5 (2) | none | ## 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. **Snowflake-managed MCP server.** Tools are governed by Snowflake roles, the SQL tool is read-only by default, and sign-in runs through Snowflake OAuth or a company identity provider. No rate limits or tool-call error codes were found in the reviewed documentation, and a person must create the account, the server object and the OAuth integration before an agent can connect. ## 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 ### Snowflake-managed MCP server 1. Send `Accept: application/json, text/event-stream` and read `tools/call` results as an SSE stream that ends with `data: [DONE]` 2. Write the account hostname with hyphens, not underscores, or some clients fail to connect 3. Check the user's `DEFAULT_ROLE` and `DEFAULT_WAREHOUSE` first. Clients that request `session:role:all` get the default role, and a missing warehouse stops the session starting 4. Keep SQL results narrow. Responses over 250 KB are truncated with no paging, and agent tool responses can pass 200 KB 5. Treat `invalid_client` from `/oauth/token-request` as a possible network policy block as well as a wrong credential ## Questions ### Which is better for AI agents, Postgres MCP Pro or Snowflake-managed MCP server?
