Implementation Reference

• src/mcp/mcp-server.js:1088-1103 (handler)

  Core handler function that implements the getModelInfo tool logic. Retrieves the model schema from storage and formats the response with name, title, description, properties, and required fields.

  async getModelInfo(args) {
      const { model } = args;
      
      const schema = await this.storage.getModel(config.storage.defaultDatabase, model);
      if (!schema) {
          throw new Error(`Model '${model}' not found`);
      }
      
      return {
          name: model,
          title: schema.title,
          description: schema.description,
          properties: schema.properties,
          required: schema.required || []
      };
  }

• src/mcp/mcp-server.js:138-144 (schema)

  Input schema validation for getModelInfo tool, defining the required 'model' string parameter.

  inputSchema: {
      type: 'object',
      properties: {
          model: { type: 'string', description: 'Model name' }
      },
      required: ['model']
  }

• src/mcp/mcp-server.js:135-145 (registration)

  Registration of the getModelInfo tool in the server's tools array, including name, description, and schema.

  {
      name: 'getModelInfo',
      description: 'Get detailed information about a model',
      inputSchema: {
          type: 'object',
          properties: {
              model: { type: 'string', description: 'Model name' }
          },
          required: ['model']
      }
  }

• src/mcp/mcp-server.js:762-764 (registration)

  Dispatch registration in the handleToolCall switch statement that calls the getModelInfo handler.

  case 'getModelInfo':
      result = await this.getModelInfo(args);
      break;

• src/mcp/index.js:457-479 (handler)

  Alternative handler implementation in index.js using MCP SDK style, similar logic but returns text content with JSON schema.

  case 'getModelInfo':
    // Check filesystem first
    let modelInfo = models.get(args.model);
    if (!modelInfo) {
      try {
        modelInfo = await storage.getModel(config.storage.defaultDatabase, args.model);
        if (modelInfo) {
          models.set(args.model, modelInfo);
        }
      } catch (error) {
        throw new Error(`Model '${args.model}' not found`);
      }
    }
    if (!modelInfo) {
      throw new Error(`Model '${args.model}' not found`);
    }
    
    return {
      content: [{
        type: 'text',
        text: `Model: ${args.model}\n\nSchema:\n${JSON.stringify(modelInfo, null, 2)}`
      }]
    };
