## Project history and usage

ctx7 is the command-line interface for Context7, an Upstash project that supplies current, version-specific library documentation to AI coding assistants.

### Project history

Context7's public repository was created in 2025 under the Upstash organization. The official docs position the platform around reducing stale or hallucinated library API answers by injecting current documentation into prompts and agent workflows.

### Adoption history

The CLI documentation targets AI coding users who want terminal access to indexed library docs and one-command setup for tools such as Claude Code, Cursor, OpenCode, and MCP-compatible agents.

### How it is used

ctx7 is used both interactively, for commands such as resolving a library and querying docs, and as a setup helper that writes MCP or skill configuration for coding agents.

### Why package nerds care

As a Homebrew formula, ctx7 packages a fast-moving AI developer-tool CLI outside the Node-only install path, making Context7 setup scriptable for users who prefer system package managers.

### Timeline
