A side-by-side look at the Sequential Thinking and Shelbymcp MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Sequential Thinking for knowledge & memory work as a local process; choose Shelbymcp for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
create_entities, create_relations, add_observations.SHELBY_API_KEY.capture_thought, search_thoughts, list_thoughts.Rows where the two servers differ are marked.
