Reduces 182 KB tool responses to 4 KB. No config. No workflow changes. Just faster, cheaper security work. --- The Problem Burp Suite's MCP extension is powerful — but its responses are enormous. A single get proxy http history call with 50 items returns 185 KB of raw HTTP wire format . That's 46,000 tokens. Per call. For data you mostly don't need. At that rate, your context window fills up after a few exchanges, and you're restarting sessions before finishing the job. --- The Solution BTK sits between Claude Code and Burp, intercepting every response and compressing it before it reaches your context window. No changes to your Burp setup. No changes to how Claude uses tools. BTK is a drop-in replacement for the Burp MCP URL in your Claude config. --- Benchmark Real measurements. Same Burp instance. Same proxy history. Both sides measured directly.
