Which one, for what

ObsessionDB E

Best for An agent that needs SQL over large ClickHouse tables, and the database's own monitoring and alerts, through one hosted MCP connection.

Ahead on

  • Agent ergonomics, 53 against 46
  • Payments & pricing, 40 against 35

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

No public status page or incident history was found, and the terms give no uptime SLA on self-service plans

Snowflake-managed MCP server C

Best 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 20
  • Schema & documentation, 61 against 43
  • Security & auth, 77 against 51
  • Maintenance & community, 55 against 28
  • Transparency & trust, 84 against 58

Watch for

No rate limits for the MCP endpoint and no JSON-RPC error codes were found in the reviewed documentation

Verdicts

ObsessionDB

The hosted MCP server uses OAuth 2.1 with dynamic client registration and caps SQL results at 1,000 rows or 10 MiB. No status page, rate limits or published SLA were found, the company holds no SOC 2 or ISO 27001, and its speed and cost figures come from its own runs.

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

ObsessionDB

  1. Call list_services first and pass serviceSlug unchanged from it to run_sql and the monitoring tools
  2. Push aggregation into SQL with GROUP BY or ORDER BY ... LIMIT. Results stop at 1,000 rows or 10 MiB and set truncated: true
  3. Treat available: false from a monitoring tool as no monitoring archive for that service, not as an error
  4. Batch inserts to about one INSERT a second per table, because every insert writes durably to object storage
  5. Expect a browser sign-in on first connect. A person must approve the OAuth consent at console.obsessiondb.com

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
