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 |
| Weather | Real-time weather data | Service account |
| EODHD | Financial market data | Service account |
| Browser Automation | Web scraping, screenshots, PDFs | Service account |
| Notifications | Email, Slack, webhooks | 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.
