Klave Mcp

@juny-klave/mcp MCP server that gives Claude the ability to negotiate prices on your behalf — autonomously, privately, and with cryptographic proof of the outcome. What it does KLAVE connects Claude to a bilateral negotiation engine. You describe what you want in plain English; Claude calls KLAVE, runs the negotiation through multiple rounds, and reports back with the settled price and a ZK proof reference. Your ceiling is cryptographically bound to the authorization token and never appears in any response — the seller never sees your budget. What You Can Negotiate Anything with a price. KLAVE does not require pre-existing listings, platform partnerships, or pre-seeded scenarios. If it has an asking price and you have a ceiling, KLAVE can negotiate it. Freight and logistics "Negotiate 200 FEU containers Shanghai to Rotterdam. They're asking $2,806. My ceiling is $2,700." Software and SaaS "Get me a better price on this CRM license. 500 seats, they want $75,000 annually. I won't go above $58,000." Employment and contracts "A contractor is asking $185/hour for a 6-month engagement. My budget is $150/hour. Negotiate it." Real estate "Negotiate our office lease renewal. Landlord wants $42/sqft. We need to be at $35 or below." Legal and settlement "Negotiate a settlement. The other party is asking $250,000. My ceiling is $180,000." Any bilateral negotiation "They're asking [X]. I won't pay more than [Y]. Negotiate."

The seller's floor price is derived server-side and never a field in any API response. leaks_detected in verify responses is sourced from the server — never hardcoded. Every negotiation generates an auditable ZK proof.
