Capsule

Overview

Capsule is a Model Context Protocol server that creates compact, source-linked context packs designed to reduce token waste for coding agents. Instead of manually copying information between tools, AI assistants can call Capsule as a set of integrated capabilities, streamlining how context flows into your coding workflows.

Capsule runs locally on your machine via the npm package capsulectx, communicating over stdio without requiring any credentials or external authentication. The current release is v0.3.3, published under the MIT license with source code available at dawitlabs/capsule on GitHub.

Capsule belongs in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Capsule, you can claim this listing to verify ownership and keep information up to date.
