  "method": "tools/call",
  "params": {
    "arguments": {

Implementation Reference

• src/handlers/types-tags.ts:26-64 (handler)

  The core handler function that implements the 'anytype_create_type' tool. It validates inputs, auto-generates missing fields like plural_name and key, constructs the request body, and makes a POST request to the Anytype API endpoint /v1/spaces/{space_id}/types.

  export async function handleCreateType(args: any) {
    const { space_id, name, plural_name, description, icon, key, layout, properties, ...typeData } = args;
    
    // Validate required fields based on API testing and best practices
    if (!name) {
      return { 
        content: [{ 
          type: 'text', 
          text: JSON.stringify({
            error: 'Missing required field',
            message: 'Field "name" is required for creating a type',
            required_fields: ['name', 'plural_name'],
            provided_fields: Object.keys(args)
          }, null, 2) 
        }] 
      };
    }
    
    // Auto-generate plural_name if not provided
    const finalPluralName = plural_name || (name.endsWith('s') ? name : name + 's');
    
    // Build request body according to API specification with required plural_name and key
    const requestBody = {
      name,
      plural_name: finalPluralName, // Required field (not documented but mandatory)
      description,
      icon,
      key: key || `${name.toLowerCase().replace(/\s+/g, '_')}_${Date.now()}`, // Generate unique key if not provided
      layout: layout || 'basic', // Default to basic layout (required field)
      properties: properties || [], // Array of property IDs
      ...typeData
    };
    
    const response = await makeRequest(`/v1/spaces/${space_id}/types`, {
      method: 'POST',
      body: JSON.stringify(requestBody),
    });
    return { content: [{ type: 'text', text: JSON.stringify(response, null, 2) }] };
  }

• src/tools/types.ts:31-47 (schema)

  The input schema definition for the 'anytype_create_type' tool, defining parameters like space_id, name, key, plural_name, etc., and marking required fields.

  {
    name: 'anytype_create_type',
    description: 'Crea un nuevo tipo de objeto',
    inputSchema: {
      type: 'object',
      properties: {
        space_id: { type: 'string', description: 'ID del espacio' },
        key: { type: 'string', description: 'Clave única del tipo' },
        name: { type: 'string', description: 'Nombre del tipo' },
        plural_name: { type: 'string', description: 'Nombre plural del tipo (se auto-genera si no se proporciona)' },
        description: { type: 'string', description: 'Descripción del tipo' },
        icon: iconSchema,
        layout: { type: 'string', description: 'Layout del tipo (default: basic)' },
        properties: { type: 'array', items: { type: 'string' }, description: 'IDs de propiedades' },
      },
      required: ['space_id', 'name'],
    },

• src/index.ts:152-153 (registration)

  Registration of the tool handler in the main switch dispatcher for CallToolRequest in the MCP server.

  case 'anytype_create_type':
    return await handleCreateType(args);

• src/index.ts:54-67 (registration)

  Import statement registering the handleCreateType handler function from types-tags module.

  import {
    handleListTypes,
    handleGetType,
    handleCreateType,
    handleUpdateType,
    handleDeleteType,
    handleListTags,
    handleGetTag,
    handleCreateTag,
    handleUpdateTag,
    handleDeleteTag,
    handleListTemplates,
    handleGetTemplate
  } from './handlers/types-tags.js';

• src/index.ts:85-93 (registration)

  Inclusion of typeTools (containing the tool schema) in the combined tools list registered with the MCP server for ListToolsRequest.

  const tools = [
    ...spaceTools,
    ...objectTools,
    ...propertyTools,
    ...typeTools,
    ...tagTools,
    ...templateTools,
    ...listTools,
  ];
