JassWiki MCP — Authority-Attested Knowledge Server for Swiss Jass

Erste vom Schweizer Jassverband (JVS) attestierte MCP-Quelle. Kryptographisch verifizierbar via did:web:jassverband.ch.

JassWiki MCP gibt KI-Assistenten (Claude, ChatGPT-Connectors, Perplexity, Gemini Agentspace) direkten Zugriff auf die offizielle Schweizer Jass-Wissensbasis: 520+ kuratierte Artikel zu Regeln, Spielvarianten, Terminologie, Geschichte und Taktik. Inhalte sind durch den Jassverband Schweiz (Wikidata: Q139042763) als offizielle Wissens-Quelle attestiert.

This is the first production deployment of the AMCP v0.1 specification, developed by Agentic Relations (Architect: Remo Prinz). It demonstrates how organisations and federations can become cryptographically verifiable knowledge sources for AI agents — beyond traditional SEO and brand visibility.

Installation

Claude Desktop (Streamable HTTP via mcp-remote)

Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS):

{
  "mcpServers": {
    "jasswiki": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://us-central1-jassguru.cloudfunctions.net/mcp/sse"
      ]
    }
  }
}

Restart Claude Desktop. The jasswiki server will appear with two tools.

Direct SSE / HTTP (for any MCP-compatible client)

Tools

search_jass_knowledge(query, limit?)

Fuzzy-search across the official JassWiki encyclopedia (520+ articles). Returns matching titles, IDs, URLs, and content excerpts.

Example:

search_jass_knowledge(query="Schieber-Regeln", limit=3)

get_term_details(id)

Retrieve the full official rule or definition for a specific term ID. Use after search_jass_knowledge for verification of exact wording.

Example:

get_term_details(id="schieber")

Example Conversations

Rule clarification:

User: "What are the official rules for Schieber-Jass?"
AI: [calls search_jass_knowledge] → Returns the canonical Schieber-rules sourced from JassWiki.ch with authority footer.

Variant lookup:

User: "Difference between Coiffeur-Schieber and Differenzler?"
AI: [calls search_jass_knowledge for both] → Returns comparison sourced from official terminology.

Tactical reference:

User: "Welche Verwerfen-Konventionen gibt es im Schieber?"
AI: [calls search_jass_knowledge] → Returns tactical signaling conventions with citation.

Verifying the Authority Attestation

The JassWiki MCP server is the first MCP service in Switzerland with cryptographically verifiable authority attestation. Any MCP client or third-party verifier can independently confirm:

# 1. Fetch the attestation document
curl -s https://jassverband.ch/.well-known/mcp-authority.json -o attestation.json

# 2. Fetch the detached Ed25519 signature
curl -s https://jassverband.ch/.well-known/mcp-authority.sig -o attestation.sig.b64url

# 3. Fetch the JVS public key (DID document)
curl -s https://jassverband.ch/.well-known/did.json | jq -r '.verificationMethod[0].publicKeyJwk.x'

# 4. Verify (Python with PyNaCl)
python3 <<'EOF'
import json, base64, urllib.request, nacl.signing
doc = json.load(open('attestation.json')); doc.pop('proof', None)
canonical = json.dumps(doc, sort_keys=True, separators=(',', ':'), ensure_ascii=False).encode('utf-8')
sig = base64.urlsafe_b64decode(open('attestation.sig.b64url').read().strip() + '==')
pub_b64 = json.load(urllib.request.urlopen('https://jassverband.ch/.well-known/did.json'))['verificationMethod'][0]['publicKeyJwk']['x']
nacl.signing.VerifyKey(base64.urlsafe_b64decode(pub_b64 + '==')).verify(canonical, sig)
print('✓ Attestation cryptographically verified — JassWiki is officially attested by Jassverband Schweiz')
EOF

The attestation is governed by JVS Vorstandsbeschluss 2026-05-04 (JVS-VS-2026-05-04-AMCP-01).

Specification: AMCP v0.1 (Authority-MCP)

JassWiki MCP is the first production implementation of AMCP v0.1 (Authority-MCP) — an extension layer on top of Anthropic's MCP that adds:

  • Identity: DID:web for the authority
  • Provenance: Ed25519 signatures on attestation documents
  • Wikidata Anchoring: every domain entity has a QID
  • Versioning: attestations are time-bounded with validFrom / validUntil
  • Citation Format: Schema.org JSON-LD pre-rendered for LLM consumption

Architect & Specification Owner: Agentic Relations — founder/architect: Remo Prinz.
The full specification will be published at agenticrelations.ch/specs/amcp. The methodology applies to any organisation, federation, public-sector body, or association that wants to become a cryptographically verifiable knowledge source in the agentic web.
