Context Engine MCP is now available for any AI coding agent
Augment's Context Engine is now available as an MCP server, bringing industry-leading semantic search to every MCP-compatible agent.
In our benchmarks, adding Context Engine improved agent performance by 70%+ across Claude Code, Cursor, and Codex. Whether you use these or any other MCP-compatible agent, you can now give it deep codebase context that makes it write better code, faster, and for fewer tokens.
What's new
- Universal MCP support: Works with Cursor, Claude Code, Zed, Kilo Code, Roo Code, and any MCP-compatible agent.
- Two modes: Local mode for active development (runs Auggie CLI locally). Remote mode for cross-repo context (connects to Augment's hosted MCP).
- 70%+ quality improvement: Measured across 300 Elasticsearch PRs with 900 attempts total.
- Faster and cheaper: MCP-enabled runs consistently required fewer tool calls and conversation turns.
Benchmark results
- Claude Code + Opus 4.5: 80% improvement
- Cursor + Claude Opus 4.5: 71% improvement (completeness +60%, correctness 5x)
- Cursor + Composer-1: 30% improvement
Why it matters
Context architecture matters as much as model choice. A weaker model with great context can outperform a stronger model with poor context. When you give the best models great context, they deliver step-function improvements in production-ready code quality.
Availability
- Available now for all Augment Code users
- 1,000 free requests until the end of February 2026
- Setup takes about 2 minutes
