Acta Mcp

veritasacta/acta-mcp

Connects Claude and other MCP clients to Veritas Acta's contestable public record system via six tools: contribute claims or predictions, respond with challenges or evidence, query existing entries, discover contested records needing attention, verify hash chain integrity, and export chains for independent verification. Built on stdio transport with optional AI provenance metadata that gets hashed into the immutable record. You'd reach for this when you want your AI assistant to participate in structured discourse where claims can be challenged, evidence linked, and the full argument chain cryptographically verified. Supports device-based auth or DPoP tokens, connects to veritasacta.com by default but configurable for other instances.
