Four ways to buy proxies.
One fits this workload.

Every FineProxy address uses IPv4. Datacenter, dedicated, and ISP proxies remain static for the plan term; rotating proxies change with each request. Static plans include unmetered traffic. The highlighted option matches this page’s primary use case: Package datacenter.

Connect once.
Then just ask.

FineProxy runs a native MCP server: paste one URL into your agent and it gets 49 cabinet tools — buying, renewals, IP rotation, allowlists, usage analytics, invoices, and support. The same operations are available through a REST API if you would rather write the calls yourself.

Then just say

  • Buy 500 datacenter proxies with SOCKS5 support in Europe
  • Export my proxy list for TCP applications as JSON
  • Update the allowed IP for my application proxy service
  • Check my workload proxies for inactive or erroring IPs
  • Show the status and billing details for my proxy plans

Restart Claude after saving the configuration. FineProxy’s 49 tools will then appear in the available tool list.

What the agent won’t do — whatever you ask

Spend your money

Six tools touch the balance and all six need wallet:spend. Leave it off the key and the agent can run everything else.

Pay more than quoted

Every purchase carries expected_total_cents from the quote. A cent of drift and the call is rejected, with nothing charged.

Cancel on a whim

The two irreversible tools refuse to run without confirm=true. Termination cannot happen as a side effect.

Charge you twice

Money calls take an idempotency_key. A retry after a timeout settles the same charge, not a second one.

Test notes

Actual throughput depends on the route, destination, network conditions, and the configuration and performance of the user’s equipment. A laptop on a 500 Mbps home internet connection reached approximately 468 Mbps in practice, while remote servers reached up to 500 Mbps in standard tests. In exceptional tests from properly configured high-performance servers in Europe and the US, throughput reached up to 700 Mbps; this is not a typical per-session result.

Excellent proxy service! The setup was quick and easy, speeds are fast, and the connection is very stable. I’ve had no issues with downtime, and the dashboard is simple to use

Traffic never metered

While other providers charge per GB or even per request, these guys stay true to their mission and offer reasonably priced datacenter proxies with unlimited bandwidth. Looked all over the internet for a service like this and quite glad I found them.

Awesome proxy service! They have different proxy types including rotating ones with no traffic limit. They got affordable prices and geo-targeting options. Easy to pay either with crypto, PayPal or cards

What is a TCP proxy and how does it work?Layer 4 relay

A TCP proxy server acts as an intermediary at the transport layer (Layer 4), forwarding raw TCP connections between clients and destination servers. It establishes two separate connections — one with the client, one with the destination — and relays data between them without inspecting packet contents. This makes TCP proxies protocol-agnostic, suitable for any TCP-based application.

What's the difference between TCP proxy and HTTP proxy?OSI layer

HTTP proxies operate at Layer 7 (application layer), understanding HTTP headers, methods, and can modify requests. TCP proxies work at Layer 4 (transport layer), forwarding raw byte streams without content inspection. Use HTTP proxies for web browsing and scraping. Use TCP proxies (or SOCKS5) for databases, SSH, gaming, and non-HTTP protocols.

What is the PROXY protocol?Preserves client IP

The PROXY protocol is a standard (created by HAProxy) that preserves original client IP addresses when traffic passes through proxies. Without it, backend servers only see the proxy’s IP. The protocol prepends a header containing client IP, destination IP, and port information to the TCP stream, enabling proper logging, authentication, and security decisions.

When should I use a TCP proxy instead of an HTTP proxy?Non-HTTP traffic

Use TCP proxies (or SOCKS5 protocol) when your application doesn’t communicate via HTTP/HTTPS. Common scenarios include: database connections (MySQL, PostgreSQL), SSH tunnels, RDP sessions, email protocols (SMTP, IMAP), gaming servers, VoIP applications, and any custom TCP-based software. HTTP proxies cannot handle these protocols.

Does FineProxy support TCP connections?Use SOCKS5

FineProxy does not provide a raw TCP proxy as a separate product, but every proxy plan includes SOCKS5 support, which fully handles TCP-level connections. SOCKS5 forwards arbitrary TCP traffic — databases, SSH, custom protocols, gaming — while adding authentication and flexible addressing on top. You get both HTTP/HTTPS and SOCKS5 access with unlimited bandwidth on the same plan, so you can route any TCP-based application through FineProxy without limitations.

Guide

TCP Proxy Server: How It Works and When You Need It?

2 min readFineProxy network team

A TCP proxy is a server that operates at the transport layer (Layer 4), forwarding raw TCP connections between clients and destination servers. Unlike HTTP proxies that understand and manipulate web traffic, TCP proxies work as transparent tunnels — they relay data packets without inspecting their contents.

This protocol-agnostic approach makes TCP proxies essential for applications beyond web browsing. When your traffic isn’t HTTP-based, a standard web proxy simply won’t work.

How TCP Proxy Differs from HTTP Proxy?

The fundamental difference lies in the OSI layer. HTTP proxies operate at Layer 7 (application layer), parsing headers, cookies, and request methods. TCP proxies function at Layer 4, handling connections based solely on IP addresses and ports.

HTTP proxies understand web traffic semantics. They can cache responses, filter content, and modify headers. TCP proxies see only byte streams — they establish a connection to the destination, then forward data bidirectionally without interpretation.

This distinction determines which proxy type suits your task. Web scraping and browser automation require HTTP/HTTPS proxies. Database connections, SSH sessions, gaming, and custom protocols require TCP-level proxying.

The PROXY Protocol: Preserving Client Information

One challenge with TCP proxy protocol implementations: the destination server sees connections originating from the proxy, not the actual client. The PROXY protocol solves this by prepending client IP information to the TCP stream, allowing backend servers to log and authenticate based on real client addresses.

FineProxy TCP Support

FineProxy does not offer a raw TCP proxy as a standalone product — and in practice, you don’t need one. SOCKS5, supported alongside HTTP/HTTPS on all FineProxy plans, fully covers TCP-level proxying. It wraps any TCP connection — databases, SSH tunnels, gaming, custom protocols — in a standardized handshake, giving you the best unlimited proxy plan to buy for applications that go beyond web traffic. Unlike a bare TCP relay, SOCKS5 adds authentication and flexible addressing while still forwarding raw byte streams without content inspection.

If your task involves web scraping or browser automation, use HTTP/HTTPS mode for optimal performance. For every other TCP-based scenario, switch the same proxy to SOCKS5 — no extra purchase required, same unlimited bandwidth, full protocol flexibility.
