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.\n\n## Before you call either\n\n### ClickHouse MCP Server\n\n1. Put a `LIMIT` on every `run_query` call. The server has no row or byte limit and the default timeout is 30 seconds\n2. Call the tool `run_query`. ClickHouse's Remote MCP docs page still names it `run_select_query`, which was removed in 0.3.0\n3. Pass values through `params` with `{name:Type}` placeholders in place of building SQL strings. Tuple and Map types can't be bound\n4. Set `include_detailed_columns` to false on `list_tables` for wide schemas. Page tokens are single-use and expire after one hour\n5. Connect with a dedicated ClickHouse user holding only the grants needed, and point `CLICKHOUSE_PORT` at the HTTP interface (8123 or 8443), not 9000\n\n### Redis MCP\n\n1. 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\n2. 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\n3. Read failures from the text. Tools return strings such as `Error ...` or an `error` key in place of an MCP error result\n4. Keep the `subscription_id` from `subscribe` or `psubscribe` and pass it to `read_messages` and `unsubscribe`. Idle subscriptions close after 300 seconds\n5. 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\n\n## Questions\n\n### Which is better for AI agents, ClickHouse MCP Server or Redis MCP?\n\nClickHouse MCP Server scores 64.6 (B) on agent readiness against Redis MCP's 55.7 (C), and leads in 6 of 7 scored categories.\n\n### Do ClickHouse MCP Server and Redis MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call ClickHouse MCP Server and Redis MCP without installing anything?\n\nClickHouse MCP Server runs on your own machine, with no hosted endpoint listed. Redis MCP runs on your own machine, with no hosted endpoint listed.\n\n### Are ClickHouse MCP Server and Redis MCP open source?\n\nYes. ClickHouse MCP Server is open source (Apache-2.0). Redis MCP is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clickhouse-mcp-server-vs-redis-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clickhouse-mcp-server-vs-redis-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clickhouse-mcp-server\", \"b\": \"redis-mcp\"}`.
