Summary
Semble launched as a local code-search tool and MCP server for coding agents, positioning itself as a faster, lower-token alternative to grep-plus-read workflows. The project emphasizes CPU-only local indexing, natural-language search, and direct integration with Claude Code, Cursor, Codex, and other MCP clients.
What changed
MinishLab released Semble as a code-search library and MCP server for local and remote repositories, with code-chunk retrieval tuned for agent workflows.
Why it matters
Code search is one of the quiet cost and latency bottlenecks in agentic software development. Semble matters because it packages retrieval as a lightweight local layer that can sit between raw filesystem search and heavier hosted retrieval stacks, making repeated repo exploration cheaper and more portable for coding agents.
Evidence excerpt
The project describes Semble as fast and accurate code search for agents, says it uses about 98 percent fewer tokens than grep-plus-read, and documents MCP setup for Claude Code, Cursor, Codex, and OpenCode.
