pAIchart MCP Hub

paichart/paichart
HTTPregistry active
Summary

A central hub that lets Claude call multiple external MCP services through a single connection while preserving per-user OAuth identity. It handles service discovery by capability, orchestrates multi-service workflows with variable passing, and validates tokens via JWKS with per-service audience scoping so leaked credentials can't be replayed. Ships with connectors for Snowflake (External OAuth), Alpha Vantage, browser automation, and notifications. Also includes delivery management primitives for POVs, phases, and tasks you can query in natural language. Reach for this when you need Claude to chain operations across services that would normally require separate MCP connections, or when building workflows that must run as the authenticated user rather than a shared service account.

pAIchart — AI-Native Delivery Management + MCP Hub

pAIchart is an MCP hub for AI-native delivery management — POVs, tasks, and phases you drive in natural language — plus a registry of external MCP services you can discover, call, and orchestrate into multi-service workflows.

Anyone can self-register a service; agents and AI clients then reach all of them through a single Hub with trust-level authentication and per-user OAuth passthrough.

What pAIchart Does

Delivery management (the core)

  • POVs → Phases → Tasks — run proof-of-value engagements as structured, AI-readable delivery plans
  • Natural-language operation — ask "Which of my POVs are at risk?" or "show open tasks for BlackEye" — no UI required
  • AI agents on your work — configure, assign, and execute agents against delivery tasks
  • Portfolio analytics — health, insights, and execution metrics across your POVs

MCP service hub

  • 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, no shared secrets
  • Per-Service Audience Scoping — Hub-minted access tokens carry a per-service audience (RFC 8707 resource indicators): each service receives a short-lived credential scoped to only itself, so a token leaked from one service can't be replayed against another. Services that validate it via JWKS can accept pAIchart-issued identity instead of static API keys in URLs.
  • Trustworthy Error-Recovery Signals — When a service call fails, the Hub returns facts an AI client can act on — the honoured timeout, the service's recent success rate, and recovery guidance that never points at a blind health check — rather than unvalidated verdicts that can mislead. Built so the client recovers on its own; see the Error Recovery Signals case study.

Get Started

pAIchart is a hosted MCP hub — nothing to install. Point your AI client at the endpoint, authenticate, and start asking in natural language.

  • Hub access: https://paichart.app/mcp
  • Connect with: Claude Desktop (GitHub OAuth) or ChatGPT (Microsoft OAuth)
  • First thing to say: "Help me get started with paichart" — or run /prompt list to see every guided workflow
  • Privacy: PRIVACY-DEMO.md — what a demo account holds, what it can do, 30-day auto-deletion

Once you're connected, try:

  • "Which of my POVs are at risk?" — delivery analytics, answered directly
  • "Discover services" — browse the registry by capability
  • "Run the prompt energy_operations_optimizer" — correlates weather forecasts with energy data into operational recommendations, a multi-service workflow across two live services

Under the Hood

Every request is either answered directly or composed into a workflow across services — and every external call runs as you, never as a shared platform account:

You (Claude Desktop / ChatGPT)
  → authenticate to the pAIchart Hub
  → ask in natural language, e.g.
      • "Which of my POVs are at risk?"            → project / analytics tools answer directly
      • "Texas energy mix + this week's weather"   → Hub composes a multi-service workflow
  → for external service calls:
      → Hub discovers services by capability, determines trust level, mints a per-service JWT
      → the external service validates it via JWKS — no shared API keys
  → operations execute as the authenticated user

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.
