Use Browser DevTools when the problem lives inside a webpage or browser runtime. It is the best first tool for request initiators, CORS failures, cache behavior, cookies, payloads, response bodies, and page-load waterfalls. Use an HTTP debugging proxy such as mitmproxy, Charles, Fiddler Everywhere, Proxyman, or HTTP Toolkit when you must capture configurable traffic from a mobile app, desktop app, command-line client, container, or several clients. A debugging proxy is also the strongest choice when you need breakpoints, rewrites, mocks, or replay.
MCP connects an AI application or agent to tools, data, prompts, and other capabilities. A2A connects independent AI agents to one another. Use MCP when an agent needs to call a database, search service, browser, API, or infrastructure tool. Use A2A when one agent needs to discover, delegate work to, exchange messages with, or receive results from another agent.
To use residential proxies with CrewAI, put the proxy configuration on the custom HTTP or browser tool that opens target websites. CrewAI coordinates agents, tasks, crews, flows, model calls, and tools; it does not automatically route a tool's network traffic.
The seven best HTTP debugging proxy tools in 2026 are mitmproxy, Charles, Fiddler Everywhere, Proxyman, HTTP Toolkit, Burp Suite, and ZAP by Checkmarx. ZAP was formerly an OWASP project, but that affiliation ended in August 2023. There is no honest universal winner. mitmproxy is the strongest choice for scripting and headless automation. Charles remains a practical desktop and mobile debugger. Fiddler Everywhere fits cross-platform teams. Proxyman offers a polished mobile-development workflow. HTTP Toolkit makes focused interception easy across browsers, terminals, Android, and Docker.
To use a residential proxy with Microsoft Agent Framework, configure the proxy on the custom HTTP or browser tool that opens target websites. Microsoft Agent Framework orchestrates the model, tool calls, sessions, middleware, and workflows. The network-aware tool sends its website requests through a Proxidize Residential Proxy.
To use a residential proxy with a Google Agent Development Kit (ADK) agent, configure the proxy on the custom HTTP or browser tool that opens target websites. ADK orchestrates the model, tools, sessions, events, callbacks and workflow. The network-aware tool sends website requests through the Proxidize Residential Proxy.
Use curl's -H or --header option to send a Hypertext Transfer Protocol (HTTP) request header. Repeat the option for multiple fields, and use --json for JavaScript Object Notation (JSON) bodies. Inspect traffic with -v, -i, -I, or -D, keep credentials out of saved commands, and review custom fields before redirects.
To use a residential proxy with Claude Browser Use, configure the proxy on the browser that your application runs for Anthropic's browser_toolset_20260801. Claude decides which browser member to call, your executor performs that action in Playwright, and Playwright sends the website traffic through a Proxidize Residential Proxy.
To use a residential proxy with the OpenAI Agents SDK, put the proxy configuration in the HTTP client or browser that your agent calls as a tool. The SDK's Agent object decides when to call the tool, while the tool sends its website request through a Proxidize Residential Proxy.
The best residential proxies in the UK in 2026 are Proxidize, Bright Data, Oxylabs, IPRoyal, and DataImpulse. Proxidize is a strong option for managed residential proxies with 195+ countries, city and ISP targeting, rotating and sticky sessions, and pricing starting at $1/GB. Bright Data and Oxylabs are better suited to large-scale and enterprise workflows, while IPRoyal and DataImpulse offer flexible options for scraping, automation, and data collection.
