Overview

MCP tool for listing context providers declared in the registry manifest.

Context providers are external services (currently MCP servers) that the bridge can query for project context. This tool reads the context_providers section of the registry manifest and returns a formatted list with each provider's type, endpoint, optional flag, and requested tool specs.

Examples:

List all context providers

rails_list_context_providers

  No registry manifest found at `%<path>s`.

  To use context providers, create a registry manifest file.
  See `#{SETUP_DOC_PATH}` for a step-by-step guide.

  Quick start — add `config/rails_ai_bridge/registry.json` to your Rails app:

  ```json
  {
    "version": "1.0.0",
    "packs": {},
    "default_stack": [],
    "context_providers": {}
  }
  ```

  Then configure the registry in `config/initializers/rails_ai_bridge.rb`:

  ```ruby
  RailsAiBridge.configure do |config|
    config.registry.registry_manifest_path = "config/rails_ai_bridge/registry.json"
  end
  ```

  Once configured, add context providers and run `rails ai:skills:list` to verify.
