Mcp Loom

Overview

Mcp Loom is a stdio MCP proxy that intercepts oversized tool results and makes them queryable through an embedded DuckDB instance. Instead of working around context limits by copying data between apps, MCP clients can call Mcp Loom as a set of tools and efficiently query large result sets directly within your AI assistant workflow.

The server runs locally via npx -y mcp-loom with no authentication required. It's built as an npm package that speaks the Model Context Protocol over stdio, keeping everything on your machine. Version v0.3.2 is available under the MIT license, with source code at buttonmonkey/mcp-loom on GitHub.

Mcp Loom is listed in the AI & Agents category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim this listing to verify ownership and keep the information up to date.
