工具是从 README 中自动提取的。维护者可以在 ## Tools 标题下列出工具,即可填充这部分内容。
An MCP server gem (rails-ai-context) that automatically introspects your Rails app’s database schema, models, routes, controllers, gems, and conventions, then exposes 13 read-only tools via the Model Context Protocol. It is built for Rails developers using AI assistants (Claude Code, Cursor, Copilot, Windsurf, OpenCode) who want the AI to understand their app without manually explaining it each session.
Add the gem (bundle add rails-ai-context), run rails generate rails_ai_context:install, then rails ai:context. This creates .mcp.json for auto-discovery by Claude Code and Cursor. Optionally start the MCP server manually with rails ai:serve or enable HTTP transport. Configuration is done in config/initializers/rails_ai_context.rb.
:standard preset)summary, standard, full) to minimize token usageA Rails application with Ruby on Rails. The gem is installed via Bundler and works with any Rails app (version 6.0+ is assumed, though not explicitly stated; the README covers Rails 7+ patterns). No external database access changes are needed.
Its MCP tools return summaries first (≈55 tokens) and only fetch full details on demand, replacing expensive full-file reads. Benchmarks in the README show a 37% token reduction on a small 5-model app; savings grow with app size.
Claude Code, Cursor, OpenCode, Windsurf, and GitHub Copilot. Claude Desktop is also supported with manual MCP configuration.
Yes. Set `config.preset = :standard` (default, 13 introspectors) or `:full` (28 introspectors, exluding `database_stats` which is PostgreSQL-only opt-in). You can also cherry-pick introspectors via `config.introspectors += %i[...]`.
All MCP tools are read-only. They query the Rails app’s internal state (e.g., `ActiveRecord::Base.connection.tables`) and never write to the database or file system. The generated context files are plain markdown/JSON and can be regenerated at any time.
