HTTP Client ​

Direct access to web APIs and HTTP endpoints with full control over request construction and response handling.

Overview ​

HTTP Client is a built-in capability that provides AI agents with powerful API integration capabilities. When enabled on your MCP Gateway, agents gain access to all standard HTTP methods with complete control over headers, authentication, and request bodies, enabling seamless integration with any REST API or web service.

Key Features ​

  • All HTTP Methods: GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS
  • Full Header Control: Custom headers for authentication and content negotiation
  • Multiple Auth Types: Bearer tokens, API keys, Basic auth, OAuth
  • Flexible Payloads: JSON, form-encoded, multipart, raw body
  • Response Handling: Automatic parsing, status codes, headers, cookies
  • Advanced Options: Timeouts, redirects, compression, proxies

How to Enable ​

  1. Navigate to your MCP Gateway settings
  2. Locate HTTP Client in the Built-in Capabilities section
  3. Toggle the capability ON
  4. Configure rate limits and allowed domains (optional)
  5. Save your configuration

Once enabled, any AI agent connected to your gateway can make HTTP requests through the MCP protocol.

Common Integrations ​

Payment Systems ​

AI agents use HTTP Client to integrate with payment processors like Stripe, PayPal, or Square for transaction processing, subscription management, and financial reporting.

Cloud Services ​

Agents interact with cloud platforms such as AWS, Google Cloud, or Azure to manage resources, retrieve metrics, and orchestrate infrastructure operations.

Communication APIs ​

Agents send notifications through services like SendGrid, Twilio, or Slack to deliver messages, alerts, and updates to users across multiple channels.

Data Sources ​

Agents fetch data from various APIs including weather services, financial markets, news feeds, and public datasets to enrich analysis and decision-making.

Enterprise Systems ​

Agents connect to CRM systems like Salesforce, ERP platforms like SAP, or project management tools like Jira to synchronize data and automate workflows.

Response Information ​

Available Response Data ​

  • Status code and status text
  • Response headers
  • Parsed body content
  • Cookie values
  • Timing metrics
  • Redirect chain

Content Processing ​

  • JSON automatically parsed
  • XML converted to structured data
  • HTML available as text
  • Binary data as base64
  • Text content as strings

Rate Limiting ​

Built-in Protection ​

  • Automatic rate limit detection
  • Respect for Retry-After headers
  • Exponential backoff strategies
  • Queue management for burst requests

Custom Limits ​

  • Configure per-domain limits
  • Set global request caps
  • Define time windows
  • Implement priority queues

Typical Applications ​

Data Synchronization ​

AI agents use HTTP Client to keep data synchronized between multiple systems, ensuring consistency across platforms and preventing data silos.

Monitoring and Alerting ​

Agents continuously check API endpoints for status, performance metrics, or data changes, sending alerts when thresholds are exceeded or issues detected.

Workflow Automation ​

Agents orchestrate complex workflows by coordinating multiple API calls, managing sequential operations, and handling conditional logic based on responses.

Report Generation ​

Agents gather data from multiple API sources, aggregate information, perform analysis, and generate comprehensive reports for decision-making.

Pricing ​

HTTP Client is included with standard MCP Gateway usage:

  • No per-request charges
  • Standard gateway request rates apply
  • Large responses (>200KB) count as multiple requests
