tesseron vs semble
tesseron: Tesseron allows live applications to declare typed actions using Zod-style builders, which MCP-compatible AI agents can invoke as tools over WebSocket. It provides a click-to-connect handshake, no browser automation, and capabilities like confirmation, elicitation, and sampling. The MCP gateway bundles with a Claude Code plugin for easy setup.; 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.
