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

Tools
Discovery
| Tool | Description |
|---|---|
get_context_tree |
Structural AST tree of a project with file headers and symbol ranges (line numbers for functions/classes/methods). Dynamic pruning shrinks output automatically. |
get_file_skeleton |
Function signatures, class methods, and type definitions with line ranges, without reading full bodies. Shows the API surface. |
semantic_code_search |
Search by meaning, not exact text. Uses embeddings over file headers/symbols and returns matched symbol definition lines. |
semantic_identifier_search |
Identifier-level semantic retrieval for functions/classes/variables with ranked call sites and line numbers. |
semantic_navigate |
Browse codebase by meaning using spectral clustering. Groups semantically related files into labeled clusters. |
Analysis
| Tool | Description |
|---|---|
get_blast_radius |
Trace every file and line where a symbol is imported or used. Prevents orphaned references. |
run_static_analysis |
Run native linters and compilers to find unused variables, dead code, and type errors. Supports TypeScript, Python, Rust, Go. |
Code Ops
| Tool | Description |
|---|---|
propose_commit |
The only way to write code. Validates against strict rules before saving. Creates a shadow restore point before writing. |
get_feature_hub |
Obsidian-style feature hub navigator. Hubs are .md files with [[wikilinks]] that map features to code files. |
