Gives Claude direct access to 520+ curated articles from JassWiki, the official Swiss Jass card game knowledge base. Two tools: search_jass_knowledge for fuzzy queries across rules, variants, and tactics, and get_term_details for full canonical definitions by ID. Notable as the first production MCP server with cryptographic authority attestation using W3C Verifiable Credentials, signed by the Jassverband Schweiz via did:web. Runs serverless on Google Cloud Functions with SSE transport. Useful if you're building Swiss cultural applications, need verified rule lookups for Jass variants like Schieber or Coiffeur, or want to see how organizations can become cryptographically verifiable knowledge sources for AI agents beyond traditional SEO.
