pAIchart — MCP Hub Platform

AI Service Orchestration with Per-User Authentication

pAIchart is a MCP service mesh where AI discovers MCP servers, composes & orchestrates multi-service workflows. Users can self-register services and connect agents or AI clients to any MCP service through a single Hub with trust-level authentication, per-user OAuth passthrough, and multi-service workflows.

What pAIchart Does

• Free Service Registration — Comprehensive guides available via "/prompt list" or as MCP resources
• Service Discovery — AI agents find services by capability, not by name
• Multi-Service Workflows — Chain services sequentially, in parallel, or conditionally with variable passing
• Per-User Authentication — Each user's operations run as themselves via External OAuth (validated with Snowflake)
• Trust Level System — 6-tier security model controls token forwarding (INTERNAL → TRUSTED → OWNER → TEAM_MEMBER → SCOPED → ANONYMOUS)
• JWKS Token Validation — RS256 asymmetric cryptography, public key verification, 95/100 security score

How It Works

User (Claude Desktop / ChatGPT) → Authenticates to pAIchart Hub → Discovers services by capability → Hub determines trust level, forwards JWT if authorized → External service validates JWT via JWKS → Operations execute as the authenticated user

Live Services

Service	Capability	Per-User Auth
Snowflake	Data warehouse queries	✅ External OAuth
EIA	U.S. energy data analytics	Service account

Register Your MCP Service

Any MCP service can register with the Hub in one command:

registry(action: "register", { name: "my-service", description: "What your service does", endpoint: "https://my-service.com/mcp", category: "data-services" })

Services that support External OAuth (like Snowflake, Databricks) get per-user authentication automatically.
