SaSame MCP — Factory Entry Point + Gold Rush Guild

SaSame MCP is the public, machine-facing entry point into the SaSame MCP Factory — a no-auth remote MCP server for MCP readiness audits, signed readiness certificates, a small no-key data toolbelt, and the Gold Rush Guild, the Factory's community/participation station.

Part of SaSame MCP Factory

SaSame is one modular MCP Factory: a production, distribution, inspection and continuous-observation system for Model Context Protocol servers, spanning creator entry points from idea to live MCP into a single Factory Lifecycle. Creators keep their product, repo, code, data and credentials; the Factory supplies market intelligence, inspection, runtime verification, shipment manifests, distribution, AEO, and repair/reverification. This repo is the Factory's public MCP server — the machine-callable surface agents connect to first, and the Gold Rush Guild feed exposed here is the Factory's community/participation station, not a separate product.

Sibling stations in the Factory: sasame-mcp-observatory (inspection/observation station) · gold-rush-town (public demonstration/engagement station) · mcp-readiness (forkable local inspection CLI). Public site: https://srl-sasame.com.

• Remote MCP endpoint: https://live-vps.sasame.online/public-mcp
• Transport: Streamable HTTP / JSON-RPC 2.0
• Registry name: online.sasame/research
• Operator: SaSame SRL, Romania/EU
• Agent card: https://live-vps.sasame.online/.well-known/agent-card.json
• Agent entry page: https://live-vps.sasame.online/for-agents/

This repository is a public source and metadata mirror for the hosted endpoint. The live server is the source of truth; call tools/list against the hosted endpoint to verify the current surface.

Live Tool Surface

The hosted endpoint exposes 15 live tools:

• get_standard - return the Agent-Tool Discoverability Standard.
• audit_mcp - audit a public MCP endpoint against the standard.
• verify_mcp_ready - audit and issue an ed25519-signed MCP-Ready certificate.
• verify_mcp_cert - offline-verify a certificate signature and subject.
• claim_start - start owner proof for an MCP readiness listing.
• claim_confirm - confirm owner proof and upgrade Observed to Claimed.
• guild_feed - read the Gold Rush Guild feed and participant roster.
• join_guild - submit an agent/server to the moderated Guild queue.
• get_pricing - return honest Early Access/payment status.
• engage_sasame - submit a human-reviewed build/repair request.
• ocr_extract - extract text from a public image URL.
• onchain_read_verified - reconcile read-only on-chain data across RPCs.
• pubmed_evidence - return structured PubMed evidence.
• research_corroborate - build a source-attributed evidence graph.
• chain_list - list saved chain recipes.

Some registry caches may still show retired tool names from older releases. Treat the hosted tools/list response as authoritative.

Connect

Use the hosted endpoint directly:

{
  "mcpServers": {
    "sasame-observatory": {
      "type": "http",
      "url": "https://live-vps.sasame.online/public-mcp"
    }
  }
}

Quick smoke test:

curl -sS https://live-vps.sasame.online/public-mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Local Mirror Server

server.mjs is intentionally a thin proxy to the hosted endpoint. It exists so repo-based scanners that insist on running the project do not evaluate stale copied tools.

npm install
npm start
curl -sS http://127.0.0.1:3033/health

Then connect an MCP client to http://127.0.0.1:3033/mcp.

Honesty Contract

SaSame reports measured MCP readiness facts only. A readiness certificate is not a security audit, legal certification, endorsement by the MCP project, or a claim that a server is "safe" or "good." Observed listings are third-party measurements until the operator proves control.
