rails-ai-context: rails-ai-context auto-introspects your Rails app and provides context to AI assistants via MCP, saving tokens and reducing discovery overhead. It generates context files for multiple AI tools and offers 11 MCP tools with smart detail levels.; CodeMCP: CKB transforms your codebase into a queryable knowledge base, enabling semantic search, impact analysis, dead code detection, ownership lookup, and more through CLI, API, or AI assistants. It reduces AI tool calls by 60-70% with compound operations and integrates seamlessly with MCP-compatible tools.
