MCP Context Provider

Implementation Reference

• src/server/index.ts:251-260 (handler)

  The 'list_available_contexts' tool handler retrieves context information from the engine, transforms it into a summary (including tool_category, description, priority, and applies_to), and returns it as a JSON-formatted string.

  case 'list_available_contexts': {
    const contexts = engine.getContexts();
    const list = Array.from(contexts.values()).map((c) => ({
      tool_category: c.tool_category,
      description: c.description,
      priority: c.metadata.priority ?? 'medium',
      applies_to: c.metadata.applies_to_tools,
    }));
    return { content: [{ type: 'text', text: JSON.stringify(list, null, 2) }] };
  }

• src/server/index.ts:94-101 (registration)

  The tool 'list_available_contexts' is defined and registered in the MCP server's listTools response.

  {
    name: 'list_available_contexts',
    description: 'List all loaded context categories and their descriptions',
    inputSchema: {
      type: 'object' as const,
      properties: {},
    },
  },
