Context Engine
VS Code extension for Context Engine — indexes your codebase and connects MCP-powered context to Claude Code, Windsurf, Augment, Cursor, Copilot, Kiro, Antigravity, and Codex.
Get Started
- Install — search "Context Engine" in VS Code Extensions, or install from the Marketplace
- Sign up at dev.context-engine.ai
- Create an API key — Account → API Keys → Create Key (starts with
ctxce_)
- Paste your API key in the extension settings panel
Your workspace starts indexing immediately. No Docker, no local stack, no configuration needed.
Features
- Continuous indexing — force sync + watch mode keeps your codebase indexed in real time
- MCP for every IDE — auto-configures
.mcp.json for Claude Code, Windsurf, Augment, Cursor, Copilot, Kiro, Antigravity, and Codex
- Prompt+ — enhances prompts with relevant codebase context before sending to your AI assistant
- Git history — indexes full git history for deeper code lineage search
- LSP enrichment — augments search results with live diagnostics from your editor
IDE Integration
Run Write MCP Config from the command palette, or enable individual IDEs in settings:
| IDE |
Setting |
| Claude Code |
mcpClaudeEnabled — writes .mcp.json to workspace root |
| Windsurf |
mcpWindsurfEnabled — writes mcp_config.json |
| Augment |
mcpAugmentEnabled — writes Augment settings.json |
| Cursor |
mcpCursorEnabled — writes ~/.cursor/mcp.json |
| Copilot |
mcpCopilotEnabled |
| Kiro |
mcpKiroEnabled |
| Antigravity |
mcpAntigravityEnabled |
| Codex |
mcpCodexEnabled |
Augment setup notes
The extension writes ~/.augment/settings.json (works on Windows, macOS, and Linux), which Augment CLI picks up automatically. If you add the servers manually in Augment's MCP panel instead:
- Set Authentication Type to Header with header
Authorization: Bearer <your API key>.
- Do not paste your
ctxce_... API key into the OAuth Client ID field — an API key is not an OAuth client ID, and authorization will fail with {"detail":"Unknown client_id"}.
- If you prefer OAuth, leave the OAuth Client ID field empty; Augment registers itself automatically and the Authorize button opens a Context Engine login page.
Run Context Engine Uploader: Augment Setup Guide (Manual MCP / Header Auth) from the command palette for step-by-step instructions and one-click copy of the header value and URLs.
