Semantic Intelligence for Large-Scale Engineering. Context+ is an MCP server designed for developers who demand 99% accuracy. By combining Tree-sitter AST parsing, Spectral Clustering, and Obsidian-style linking, Context+ turns a massive codebase into a searchable, hierarchical feature graph.

Context+ is an MCP server that provides semantic intelligence for large-scale engineering projects by combining AST parsing, spectral clustering, and Obsidian-style linking. It helps developers understand, navigate, and manage their codebase with high accuracy and AI-powered tools for discovery, analysis, and code operations.

Features

01Semantic Code Understanding: Leverages Tree-sitter AST parsing, Spectral Clustering, and Obsidian-style linking to create a searchable, hierarchical feature graph.
02Advanced Code Discovery: Offers tools like `semantic_code_search` and `semantic_navigate` to search by meaning and browse semantically related files and identifiers.
03Comprehensive Code Analysis: Provides `get_blast_radius` for tracing symbol usage and `run_static_analysis` for finding errors across multiple programming languages.
04Safe Code Operations & Versioning: Includes `propose_commit` for rule-validated commits and a shadow restore point system for undoing AI changes without affecting Git history.
05Multi-language Support: Supports static analysis for TypeScript, Python, Rust, Go, and multi-language AST parsing across 43 extensions.

Use cases

↳Large Codebase Navigation: Developers can use semantic search and clustering to efficiently understand code structure and relationships within massive projects.
↳Impact Analysis for Changes: Before implementing modifications, `get_blast_radius` helps identify all affected areas to prevent orphaned references and ensure code integrity.
↳Automated Code Quality Checks: Integrate `run_static_analysis` into CI/CD pipelines to automatically find dead code, unused variables, and type errors across various languages.
↳AI-Assisted Code Writing: Utilize `propose_commit` to validate AI-generated or manually written code against strict rules before saving, ensuring high quality and adherence to standards.
↳Undoing AI Modifications Safely: Leverage shadow restore points to easily revert specific AI-driven changes without altering the project's Git history, providing a safe sandbox for AI experimentation.

    Obsidian-style linking for code navigation is an interesting UX pattern for large repositories.

    The AST-based approach means language-aware chunking, not arbitrary text splitting.

    99% accuracy claim for large-scale codebases is ambitious, but the underlying approach is sound.

    Semantic intelligence for engineering-scale codebases is what's missing from most MCP context servers.

  • Sasha Lee
    Sasha LeeMar 27, 2026

    Tree-sitter AST parsing + Spectral Clustering for code context is genuinely more accurate than text-based approaches.
