Flipt MCP Server

Implementation Reference

• src/index.ts:346-376 (handler)

  Registration and inline handler implementation for the 'delete_flag' MCP tool. Includes input schema validation with Zod, calls fliptClient to delete the flag, and formats success/error responses.

  server.tool(
    'delete_flag',
    {
      namespaceKey: z.string().min(1),
      key: z.string().min(1),
    },
    async args => {
      try {
        await fliptClient.deleteFlag(args.namespaceKey, args.key);
        return {
          content: [
            {
              type: 'text',
              text: `Deleted flag ${args.key} in namespace ${args.namespaceKey}`,
            },
          ],
        };
      } catch (error: any) {
        console.error('Error deleting flag:', error);
        return {
          content: [
            {
              type: 'text',
              text: `Failed to delete flag: ${error.message}`,
            },
          ],
          isError: true,
        };
      }
    }
  );

• src/index.ts:348-351 (schema)

  Zod input schema defining namespaceKey and key parameters for the delete_flag tool.

  {
    namespaceKey: z.string().min(1),
    key: z.string().min(1),
  },

• src/services/fliptClient.ts:182-190 (helper)

  Supporting utility in FliptClient that wraps the generated API call to delete a flag.

  async deleteFlag(namespaceKey: string, key: string) {
    try {
      await this.flagsApi.deleteFlag(namespaceKey, key);
      return { success: true };
    } catch (error) {
      console.error('Error deleting flag:', error);
      throw error;
    }
  }
