semble vs seq-mcp-server

semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.; seq-mcp-server: seq-mcp-server is a Model Context Protocol server that provides tools for searching and streaming events from Seq. It supports flexible filter expressions, workspace-specific API keys, and automatic fallback for older Seq versions. The server can be installed as a .NET global tool or built from source, and integrates easily with MCP clients like Claude Desktop.
