AuthHub MCP Server

Native JSON-RPC 2.0 Engine, Dynamic Tool Registries & SSE Real-Time Streaming

Deploy AuthHub as your primary MCP Server. Connect Anthropic Claude Desktop, Cursor, Zed, or autonomous agent fleets directly via HTTP SSE. AuthHub delivers spec-compliant JSON-RPC 2.0 lifecycle management, adaptive tool discovery based on caller identity, cryptographic Merkle audit anchoring, and real-time tool push notifications.

Protocol Conformance

Complete Model Context Protocol Surface

Full compliance with official MCP specifications across all standard methods, error codes, and transport mechanisms.

Multi-Version Negotiation

Supports MCP spec versions 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26, and 2024-11-05. Echoes client version or negotiates gracefully during initialize.

Adaptive Tool Catalog

Dynamically generates tools/list based on the authenticated user's relationship graph in SpiceDB. Agents only see tools they are authorized to call, eliminating prompt window clutter and token waste.

Server-Sent Events (SSE) Stream

Supports persistent HTTP streaming via GET /mcp with Accept: text/event-stream. Delivers server notifications, list change events, and execution progress in real time.

Context Resources & Templates

Serves contextual documentation, database schemas, and clinical guidelines via resources/list and resources/read. Supports dynamic URI parameter templates.

Governed Prompt Templates

Provides curated prompt templates via prompts/list and prompts/get. Standardizes clinical reasoning steps, database query constraints, and multi-step workflows.

Merkle Tree Audit Anchoring

Every tool execution is hashed, anchored into a cryptographic Merkle tree in CockroachDB, and mirrored to immutable MinIO S3 object storage for 7-year regulatory compliance.
