octocode

Overview

Octocode is a structural code intelligence tool that analyzes codebases using tree-sitter AST parsing to build a knowledge graph of relationships between files. It exposes this through an MCP server, providing AI assistants with semantic search capabilities, code signature viewing, and graph-based relationship queries. Unlike standard RAG which treats code as flat text, Octocode understands actual imports, dependencies, and function calls across files.

After installing, here are 5 things you can ask your AI assistant:

• semantic_search

  Find code by meaning using natural language queries

  Try:Where is user authentication implemented?Try:Find all places we handle database errorsTry:What is the payment processing flow?
• view_signatures

  View file structure including function signatures and imports

  Try:Show me the structure of src/auth/login.rsTry:What functions are exported by the payment module?Try:Display the class definitions in api/handlers.rs
• graphrag

  Query relationships between files and code elements

  Try:What files depend on the payment module?Try:What calls the authenticate function?Try:Show all imports in the checkout module
• structural_search

  Find specific code patterns using AST matching

  Try:Find all .unwrap() calls in the codebaseTry:Locate all new PaymentProcessor instantiationsTry:Find all error handling patterns in the API layer

FAQ

What programming languages does Octocode support?

Octocode supports Rust, Python, TypeScript/JavaScript, Go, PHP, C++, and Ruby with full AST parsing and structural understanding.

How is Octocode different from standard code search tools?

Unlike standard tools that search text, Octocode builds a knowledge graph of actual code relationships (imports, calls, dependencies) and provides semantic search combined with structural understanding.
