Zero-Key Market Data MCP for DeepSeek Harness Ecosystem

Description and use

Zero‑Key Market Data MCP lets agents fetch market data without keys or signup, aggregating free public sources for reliable, marketing‑aligned insights.

Problem

Agents need market data without API keys, raw endpoints, or complex integration, yet require aggregated, reliable, and marketing‑aligned data.

Outcome

Agents can now access market data without keys or signup, reducing integration friction and improving data reliability for marketing workflows.

Workflow

• 1. Deploy mrd MCP server (GitHub repo).
• 2. Point MCP‑compatible agent to mrd endpoint.
• 3. Agent queries market data (e.g., "is gold up today").
• 4. mrd aggregates free public sources, normalizes schema, caches 24h, and applies fallback chain.
• 5. Agent receives consistent, reliable data for downstream marketing or research tasks.

Evidence

No API key, no signup, no BYOK bill. Market quotes come from free public endpoints…
