Fastly NGWAF MCP Server

Instructions

Implementation Reference

• server.js:993-996 (handler)

  Handler logic in the CallToolRequestSchema that processes the delete_corp_rule tool call, resolves the corpName using context, and invokes the client helper.

  case 'delete_corp_rule':
      const { corpName: corpForDeleteRule } = resolveContext(typedArgs);
      result = await client.deleteCorpRule(corpForDeleteRule, typedArgs.ruleId);
      break;

• server.js:607-614 (schema)

  Input schema definition for the delete_corp_rule tool, specifying parameters corpName (optional) and required ruleId.

  inputSchema: {
      type: 'object',
      properties: {
          corpName: { type: 'string', description: 'Corporation name (uses context default if not provided)' },
          ruleId: { type: 'string', description: 'Rule ID to delete' },
      },
      required: ['ruleId'],
  },

• server.js:604-615 (registration)

  Tool registration in the tools array returned by ListToolsRequestSchema, defining name, description, and schema for delete_corp_rule.

  {
      name: 'delete_corp_rule',
      description: 'Delete a corporation-level rule',
      inputSchema: {
          type: 'object',
          properties: {
              corpName: { type: 'string', description: 'Corporation name (uses context default if not provided)' },
              ruleId: { type: 'string', description: 'Rule ID to delete' },
          },
          required: ['ruleId'],
      },
  },

• server.js:134-136 (helper)

  FastlyNGWAFClient helper method that performs the actual DELETE API request to remove a corporation rule.

  async deleteCorpRule(corpName, ruleId) {
      await this.api.delete(`/corps/${corpName}/rules/${ruleId}`);
      return { success: true };

• server.js:387-394 (helper)

  Utility function resolveContext used by the handler to determine corpName and siteName from arguments or default context.

  function resolveContext(args) {
      const corpName = args.corpName || context.defaultCorpName;
      const siteName = args.siteName || context.defaultSiteName;
      if (!corpName) {
          throw new Error('Corporation name is required. Please set context or provide corpName parameter.');
      }
      return { corpName, siteName };
  }
