peta-core vs semble
peta-core: Peta Core is a control-plane runtime for MCP, providing gateway routing, credential vault, policy enforcement, and audit logging. It sits between AI agents and downstream MCP servers, enabling secure and observable tool calls.; 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.
