Configuration

Two configuration methods (not attributes) turn a domain into grouped facades — see Tool grouping:

# config/initializers/mcp_authorization.rb
McpAuthorization.configure do |config|
  config.server_name    = "my-app"
  config.server_version = "1.0.0"

  # Build a context from each MCP request.
  # Return anything that responds to .current_user.can?(symbol).
  config.context_builder = ->(request) {
    user = User.authenticate(request.headers["Authorization"])
    OpenStruct.new(current_user: user)
  }
end

Options🔗

Option	Default	Description
`server_name`	`"mcp-authorization"`	Name in MCP handshake
`server_version`	`"1.0.0"`	Version in MCP handshake
`mount_path`	`"/mcp"`	URL prefix for MCP endpoints
`default_domain`	`"default"`	Domain when no `:domain` segment in path
`tool_paths`	`["app/mcp"]`	Directories where tool classes live (relative to Rails.root)
`tool_producers`	`[]`	Callables that register tool classes built at runtime — see Generated tools
`shared_type_paths`	`["sig/shared"]`	Directories where shared `.rbs` type files live
`context_builder`	required	`(request) -> context`
`cli_context_builder`	`nil`	`(domain:, role:) -> context` for rake tasks
`strict_schema`	`false`	Emit stricter compiled schemas
`tools_list_cache`	`nil`	`:memory`, `:redis`, or any object responding to `get`/`set` — see Caching `tools/list`
`tools_list_cache_ttl`	`3600`	Per-entry TTL in seconds
`tools_list_cache_redis`	`nil`	Explicit Redis client for the `:redis` store
`tools_list_cache_redis_url`	`nil`	Explicit Redis URL; falls back to `ENV["REDIS_URL"]`, then `Redis.new`

Two configuration methods (not attributes) turn a domain into grouped facades — see Tool grouping:

Method	Purpose
`facet_domain :domain, group_by: :category, ...`	Present this domain as one facade tool per category. Optional `schema_strategy:`, `uncategorized:`, `facade_suffix:`.
`categories { summary :key, "text" }`	Declare one summary line per group, used as each facade description's lead.
