  Phos Labs is an independent studio that sells behavioral-science "commerce intelligence" to AI agents:
  diagnose where a funnel loses customers, redesign a checkout, rewrite offer copy, optimize price framing
  and detect cognitive biases. The surface is a Bearer-key REST API at phoslabs.io/api/v1 (OpenAPI 3.0.3, 7
  operations, an anonymous tool-and-price listing) and a hosted MCP server at mcp.phoslabs.io behind OAuth 2.1
  with RFC 8414 / RFC 9728 discovery and dynamic client registration, listed twice in the official MCP
  registry and described by an A2A-shaped agent card with nine skills. Billing is prepaid credits (1 credit =
  EUR 0.01) debited per call, with x402 USDC micropayments stated but not verifiable. The same domain also
  hosts Mind of Granite, a consumer decision-guidance product.

  description: >-
    Hosted, remote Model Context Protocol server. POST https://mcp.phoslabs.io/mcp is Streamable HTTP
    behind OAuth 2.1: the 401 challenge names RFC 9728 protected-resource metadata, whose authorization
    server (https://mcp.phoslabs.io/) publishes RFC 8414 metadata with authorization_code + refresh_token,
    PKCE S256, dynamic client registration and one scope, claudeai. The root path answers an anonymous
    initialize (protocolVersion 2025-03-26, serverInfo "Phos Labs Commerce Intelligence") and refuses
    every other method; /sse and /messages accept a REST API key as the Bearer token. Registered in the
    official MCP registry as io.phoslabs/commerce-intelligence (4.0.0) and io.phoslabs/behavioral-science
    (1.0.0). tools/list is gated, so the tool inventory is recorded from the agent card and REST listing
    without input schemas. The A2A agent card served on this host at /.well-known/agent-card.json (and
    agent.json) describes this server and grades flavored (no protocolVersion).
