Module: RubynCode::MCP::ToolBridge

Defined in:
lib/rubyn_code/mcp/tool_bridge.rb

Overview

Wraps MCP tools as native RubynCode tools by dynamically creating tool classes that delegate execution to the MCP client.

Each bridged tool:

  • Has TOOL_NAME prefixed with “mcp_”

  • Has RISK_LEVEL = :external

  • Delegates #execute to the MCP client’s #call_tool

  • Registers itself with Tools::Registry

A server’s resources and prompts are bridged separately by ServerExtrasBridge, which #bridge folds into the returned classes.

Class Method Details

.bridge(mcp_client) ⇒ Array<Class>

Discovers tools from an MCP client and creates corresponding RubynCode tool classes (plus any resource/prompt bridge tools).

Parameters:

Returns:

  • (Array<Class>) —

    the dynamically created tool classes

def bridge(mcp_client)
  classes = Array(mcp_client.tools).map { |tool_def| build_tool_class(mcp_client, tool_def) }
  classes.concat(ServerExtrasBridge.bridge_resources(mcp_client))
  classes.concat(ServerExtrasBridge.bridge_prompts(mcp_client))
  classes
end

.sanitize_name(name) ⇒ String

Sanitizes a tool name into a Ruby-friendly identifier. Public so ServerExtrasBridge names its resource/prompt tools the same way.

Parameters:

  • name (String) —

    the original tool name

Returns:

  • (String) —

    sanitized name
