HORIZON SHIELD KIRA MCP Server
Remote Model Context Protocol server at https://mcp.horizonshield.dev/ (Streamable HTTP, POST only, protocol 2025-06-18, serverInfo horizon-shield 1.0.9, listed on registry.modelcontextprotocol.io as dev.horizonshield/horizon-shield). Anonymous: initialize, tools/list (15 tools with inputSchema, outputSchema and read-only annotations) and prompts/list (5) need no key. Tools return fair min/avg/max price ranges and an overcharge danger threshold for 61 Japanese work categories, audit a quoted JPY price, scan estimate wording for known high-pressure tactics, issue SHA-256 tamper-evident receipts with a public verify URL, verify such receipts fail-closed, create an AP2 FairPriceAttestation (the one ledger-appending tool), and look up verification-passed contractors on Yakumo. Also installable as a Claude Code plugin and a Gemini CLI extension that connect to the same URL.
