Context+

What it does

Context+ is a powerful MCP server that provides semantic intelligence for large-scale software engineering. It transforms massive codebases into a searchable, hierarchical feature graph by combining Retrieval-Augmented Generation (RAG), Tree-sitter AST parsing, Spectral Clustering, and Obsidian-style linking.

Tools

• get_context_tree: Provides a structural AST tree of a project with file headers and symbol ranges.
• get_file_skeleton: Extracts function signatures and class methods to show the API surface without full bodies.
• semantic_code_search: Performs meaning-based search using embeddings over file headers and symbols.
• semantic_identifier_search: Retrieves specific functions, classes, or variables with ranked call sites.
• semantic_navigate: Browses the codebase by meaning using spectral clustering to group related files.
• get_blast_radius: Traces every file and line where a symbol is imported or used to prevent orphaned references.
• run_static_analysis: Executes native linters and compilers to find dead code and type errors (TS, Python, Rust, Go).
• propose_commit: The primary tool for writing code, featuring strict validation and shadow restore points.
• get_feature_hub: A navigator for Obsidian-style .md files that map features to code files via wikilinks.
• upsert_memory_node: Creates or updates memory nodes with auto-generated embeddings.
• search_memory_graph: Combines semantic search with graph traversal to find direct and neighboring matches.
