# pAIchart MCP Hub
> AI-native service orchestration platform. Discover MCP services by capability, chain multi-service workflows at runtime, and authenticate per-user via JWKS/External OAuth.
pAIchart MCP Hub enables AI agents to discover, compose, and execute multi-service workflows dynamically. Unlike traditional automation platforms (Zapier, n8n) that require humans to pre-design every workflow, MCP Hub lets AI reason about goals and assemble the right services at runtime with per-user authentication, trust-level security, and business context awareness.
## Getting Started
- [Connect to pAIchart](https://paichart.app): Sign in with GitHub, Google, or Microsoft OAuth
- [MCP Hub UI](https://paichart.app/mcp): Service registry, workflows, and management interface
- [JWKS Endpoint](https://paichart.app/api/auth/jwks): Public key endpoint for JWT validation (RS256)
Once connected via MCP (Claude Desktop, ChatGPT, or custom client), all documentation is available through built-in prompts and resources:
- `/prompt list` — List all available workflow guides and tutorials
- `/prompt register_guide` — Step-by-step service registration tutorial
- `/prompt get_started` — Interactive onboarding with role-based paths
- `/prompt workflow_guide` — Multi-service workflow orchestration guide
- `services(action: "discover")` — Find services by capability or category
- `registry(action: "register")` — Register your own MCP service (one command)
- MCP Resources: `mcp://hub/services`, `mcp://hub/workflows`, `mcp://hub/analytics`
## Key Capabilities
- AI-native service discovery by capability (not by name)
- Per-user JWT authentication via JWKS (RS256, 95/100 security score)
- External OAuth for Snowflake, Databricks, Azure SQL (user's own identity, not stored credentials)
- 6-tier trust level system (INTERNAL, TRUSTED, OWNER, TEAM_MEMBER, SCOPED, ANONYMOUS)
- Multi-service workflow chaining (sequential, parallel, conditional execution modes)
- Works with Claude Deskt
