Implementation Reference

• src/tools/zap.ts:291-298 (handler)

  MCP tool handler for 'zap.send_request' that delegates to ZAPClient.sendRequest

  async ({ url, method = 'GET', headers, body }: any): Promise<ToolResult> => {
    const client = getZAPClient();
    if (!client) {
      return formatToolResult(false, null, 'ZAP client not initialized');
    }
    const result = await client.sendRequest(url, method, headers, body);
    return formatToolResult(result.success, result.data, result.error);
  }

• src/tools/zap.ts:267-289 (schema)

  Input schema definition for the 'zap.send_request' tool

  inputSchema: {
    type: 'object',

        type: 'string',
        description: 'Target URL',
      },
      method: {
        type: 'string',
        description: 'HTTP method (GET, POST, PUT, DELETE, etc.)',

      },
    },
    required: ['url'],
  },

• src/integrations/zap.ts:293-326 (helper)

  Core ZAPClient.sendRequest method that implements the HTTP request sending via ZAP's REST API endpoints

  async sendRequest(url: string, method: string = 'GET', headers?: Record<string, string>, body?: string): Promise<ZAPScanResult> {
    try {
      const params: any = { url, method };
      if (headers) {
        // ZAP expects headers as a string in format "HeaderName: HeaderValue"
        params.headers = Object.entries(headers)
          .filter(([k]) => k.toLowerCase() !== 'content-length') // Remove content-length, ZAP will add it
          .map(([k, v]) => `${k}: ${v}`)
          .join('\n');
      }
      if (body) params.body = body;
  
      // Try /core/action/sendRequest/ first, fallback to /httpSender/action/sendRequest/
      try {
        const response = await this.client.get('/core/action/sendRequest/', { params });
        return {
          success: true,
          data: response.data,
        };
      } catch (coreError: any) {
        // Fallback to httpSender endpoint
        const response = await this.client.get('/httpSender/action/sendRequest/', { params });
        return {
          success: true,
          data: response.data,
        };
      }
    } catch (error: any) {
      return {
        success: false,
        error: error.message || 'Failed to send request',
