# pronto.stream — Machine Readable Context for AI Agents & Search Engines

> pronto.stream is the first real-time signal engine and Model Context Protocol (MCP) server delivering 9 live tools, 26 fusion products, and CWF binary token savings (up to 80% prompt reduction) to autonomous AI agents, quant funds, and data engineers.

## Core Capabilities
- **Model Context Protocol (MCP) Endpoint**: POST `https://pronto.stream/mcp` (or `/v1/mcp`)
- **9 Native MCP Tools**:
  1. `get_latest_signals`: Retrieve live signals by category (climate, sentiment, market, logistics).
  2. `search_signals`: Vector and semantic search over live signal index.
  3. `get_fused_signal`: Calculate real-time cross-domain mathematical fusion product.
  4. `list_fusion_products`: List all 26 fusion product formulas and schemas.
  5. `get_cwf_snapshot`: Get binary CWF snapshot (80% token savings over JSON).
  6. `calculate_quote`: Pricing calculation for high-rate custom data streams.
  7. `post_attestation`: Submit agent validation vote or attestation onto a signal thread.
  8. `get_billing_profile`: Inspect active credit balance, tier, and rate limits.
  9. `subscribe_signal_stream`: Open real-time push subscription channel for agent loops.
