Implementation Reference

src/index.ts:433-462 (handler)

Handler function for the 'get-entity-attribute' MCP tool. Delegates to PowerPlatformService.getEntityAttribute and formats the response as text.

  async ({ entityName, attributeName }) => {
    try {
      // Get or initialize PowerPlatformService
      const service = getPowerPlatformService();
      const attribute = await service.getEntityAttribute(entityName, attributeName);
      
      // Format the attribute as a string for text display
      const attributeStr = JSON.stringify(attribute, null, 2);
      
      return {
        content: [
          {
            type: "text",
            text: `Attribute '${attributeName}' for entity '${entityName}':\n\n${attributeStr}`,
          },
        ],
      };
    } catch (error: any) {
      console.error("Error getting entity attribute:", error);
      return {
        content: [
          {
            type: "text",
            text: `Failed to get entity attribute: ${error.message}`,
          },
        ],
      };
    }
  }
);

src/index.ts:429-432 (schema)

Zod input schema defining parameters for entityName and attributeName.

{
  entityName: z.string().describe("The logical name of the entity"),
  attributeName: z.string().describe("The logical name of the attribute")
},

src/index.ts:426-465 (registration)

Registration of the 'get-entity-attribute' tool using server.tool, including schema and handler.

server.tool(
  "get-entity-attribute",
  "Get a specific attribute/field of a PowerPlatform entity",
  {
    entityName: z.string().describe("The logical name of the entity"),
    attributeName: z.string().describe("The logical name of the attribute")
  },
  async ({ entityName, attributeName }) => {
    try {
      // Get or initialize PowerPlatformService
      const service = getPowerPlatformService();
      const attribute = await service.getEntityAttribute(entityName, attributeName);
      
      // Format the attribute as a string for text display
      const attributeStr = JSON.stringify(attribute, null, 2);
      
      return {
        content: [
          {
            type: "text",

          },
        ],
      };
    } catch (error: any) {
      console.error("Error getting entity attribute:", error);
      return {
        content: [
          {
            type: "text",
            text: `Failed to get entity attribute: ${error.message}`,
          },

// PowerPlatform entity relationships
server.tool(

src/PowerPlatformService.ts:165-167 (helper)

Supporting method in PowerPlatformService that performs the actual API request to fetch the specific entity attribute metadata.

async getEntityAttribute(entityName: string, attributeName: string): Promise<any> {
  return this.makeRequest(`api/data/v9.2/EntityDefinitions(LogicalName='${entityName}')/Attributes(LogicalName='${attributeName}')`);
}
