AI agents are flying blind

Your coding agent doesn't understand your codebase structure. It uses grep to search — missing semantic meaning. It reads whole files — wasting context tokens. It can't trace call chains, find dead code, or understand module boundaries. CodeSift changes that.

What you get

39 tools, one MCP server

Intelligent Search

requires setup

BM25F ranking with centrality bonus. Semantic search with embeddings. Token-budget-aware results.

Code Graph

Call chains, impact analysis, HTTP route tracing. Understand how your code connects.

LSP Bridge

requires setup

Go-to-definition, type info, cross-file rename. Language server precision without the setup.

Analysis Suite

Dead code, complexity ranking, clone detection, hotspots, 9 built-in anti-patterns.

Cross-Repo Search

Search symbols and text across all indexed repos. One query, all your projects.

Context Levels

L0 full source to L3 directory overview. Control token density per query.

Ask your AI agent anything

// Ask your AI agent:
"Search for authentication logic in the codebase"

// CodeSift returns ranked results:
// ✓ src/auth/guard.ts — AuthGuard (BM25: 0.92)
// ✓ src/middleware/session.ts — validateSession (BM25: 0.87)
// ✓ src/utils/jwt.ts — verifyToken (BM25: 0.81)
// Total: 1,291 tokens (vs 2,985 with grep)
