Flipt MCP Server

Implementation Reference

• src/index.ts:888-920 (handler)

  MCP server.tool registration, input schema (zod), and handler function that executes delete_variant tool logic by calling fliptClient service.

  server.tool(
    'delete_variant',
    {
      namespaceKey: z.string().min(1),
      flagKey: z.string().min(1),
      variantId: z.string().min(1),
    },
    async args => {
      try {
        await fliptClient.deleteVariant(args.namespaceKey, args.flagKey, args.variantId);
  
        return {
          content: [
            {
              type: 'text',
              text: `Successfully deleted variant ${args.variantId} from flag ${args.flagKey}`,
            },
          ],
        };
      } catch (error: any) {
        console.error('Error deleting variant:', error);
        return {
          content: [
            {
              type: 'text',
              text: `Failed to delete variant: ${error.message}`,
            },
          ],
          isError: true,
        };
      }
    }
  );

• src/services/fliptClient.ts:576-584 (helper)

  fliptClient service method that wraps the generated API call to delete a variant.

  async deleteVariant(namespaceKey: string, flagKey: string, id: string) {
    try {
      await this.variantsApi.deleteVariant(namespaceKey, flagKey, id);
      return { success: true };
    } catch (error) {
      console.error('Error deleting variant:', error);
      throw error;
    }
  }

• src/generated/api/apis/VariantsServiceApi.ts:241-244 (helper)

  Generated API method in VariantsServiceApi for deleting variant (partial, main impl earlier in file).

  * @params response Response returned by the server for a request to deleteVariant
  * @throws ApiException if the response code was not in [200, 299]
