Implementation Reference

• server.js:997-1003 (handler)

  Handler logic in the CallToolRequestSchema that resolves context, validates siteName, and calls the client deleteSiteRule method.

  case 'delete_site_rule':
      const { corpName: corpForDeleteSiteRule, siteName: siteForDeleteRule } = resolveContext(typedArgs);
      if (!siteForDeleteRule) {
          throw new Error('Site name is required. Please set context or provide siteName parameter.');
      }
      result = await client.deleteSiteRule(corpForDeleteSiteRule, siteForDeleteRule, typedArgs.ruleId);
      break;

• server.js:619-627 (schema)

  Input schema defining parameters for the delete_site_rule tool: corpName, siteName (optional, uses context), required ruleId.

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

• server.js:616-628 (registration)

  Registration of the delete_site_rule tool in the tools list provided to the MCP server.

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

• server.js:138-141 (helper)

  Underlying API client method in FastlyNGWAFClient that performs the DELETE request to remove a site rule.

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