SpiritWave Labs — Pentamancy Council MCP Server

Exposes the SpiritWave Labs Pentamancy Council (five-oracle divination engine) to AI agents via the Model Context Protocol.

Tools

consult_council

Consults five ancient oracles in parallel and synthesizes their readings into a single unified counsel:

• Hafez — Persian Sufi poetry (Fal-e Hafez)

• Tarot — Rider-Waite 78-card deck, 3-card spread

• Runes — Elder Futhark, 3-rune draw

• I Ching — Book of Changes, coin-cast hexagram

• Geomancy — Arabic `Ilm al-Raml, shield chart

The server draws all five, interprets each, then synthesizes. Best for questions of substance — major decisions, emotional crossroads, spiritual direction.

Input: { question: string } (3–1000 chars)

Individual consultations

consult_hafez, consult_tarot, consult_iching, consult_runes, consult_geomancy — each draws its own tradition server-side and interprets it in that tradition's voice. The tool descriptions are written so agents route themselves; there is deliberately no router tool.

Payments (x402)

Paid from day one. $0.50 per Council reading, $0.10 per individual oracle, in USDC on Base via the x402 protocol:

• initialize, tools/list, notifications — free. Connect, discover, read the prices.

• tools/call on a paid tool without payment → HTTP 402 with paymentRequirements in the body (scheme exact, payee address, atomic amount).

• Retry with the X-PAYMENT header (signed EIP-3009 payload); the x402 Foundation facilitator verifies and settles, the call proceeds, and the settlement receipt returns in X-PAYMENT-RESPONSE.

Agents using x402-fetch (or any x402-aware client) get this flow automatically. Configuration: X402_PAYEE, X402_FACILITATOR, X402_ENABLED (see docker-compose.yml).

Architecture

This is a thin proxy. The MCP server receives JSON-RPC tool calls and forwards them to the existing SpiritWave Labs PHP API:

Agent → MCP server (this repo, Streamable HTTP) → PHP API (temple.php, individual oracle endpoints) → DeepSeek

The divination engine lives entirely in the PHP backend. This server adds the MCP protocol layer — it does not implement any divination logic itself.

Transport

Streamable HTTP (the MCP standard for remote servers). Single endpoint: POST /mcp.

Setup

npm install
npm run build     # compile TypeScript
npm start         # run the compiled server
# or for development:
npm run dev       # run via tsx with hot reload

Configuration

Roadmap

• Phase 1 (done): MCP scaffold, six tools, deployed at mcp.spiritwavelabs.com (Docker, behind nginx, healthy since 2026-08-18).

• Phase 2: x402 payment layer — per-call USDC payment via Coinbase CDP facilitator (Base network). Agents pay per reading.

• Phase 3: Registry listing — official MCP Registry, Smithery, Glama.
