pAIchart
AI-native service orchestration platform. Discover MCP services by capability, chain multi-service-workflows at runtime, and authenticate per-user via JWKS/External OAuth. A single pAIchart MCP server needs only 10 tools to access hundreds of registered local or network MCP servers solving the context issue individual MCP server tools impose. Enabled by pAIchart's service_call innovation.

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.
