Self-hosted AI agent orchestration platform: dispatch tasks, run multi-agent workflows, monitor spend, and govern operations from one mission control dashboard.

Unique: Combines session-based auth with API key support and optional Google OAuth approval workflow; uses scrypt for password hashing and stores all credentials in SQLite without external identity providers, enabling self-hosted deployments

vs others: Simpler than enterprise IAM systems (Okta, Auth0) for small teams while supporting both interactive and programmatic access; approval workflow for OAuth adds human oversight without requiring external policy engines

via “authentication and authorization with role-based access control”

AI Observability & Evaluation

Unique: Implements RBAC at both API and database layers, ensuring authorization is enforced consistently across GraphQL, REST, and direct database access. Supports both API key and OAuth2/OIDC authentication mechanisms.

vs others: Role-based access control enables multi-tenant deployments where different teams can access the same Phoenix instance with appropriate data isolation, unlike single-user deployments.

via “api-authentication-and-authorization”

Robust, fast, scalable, and sandboxed open-source online code execution system for humans and AI.

Unique: Supports both API key and JWT authentication with per-user rate limiting and role-based authorization, enabling multi-tier access control without external auth systems

vs others: Simpler than OAuth-based auth for internal systems; built-in rate limiting prevents abuse without external services; role-based authorization enables tiered feature access

via “api key and oauth authentication with multi-tenant access control”

MCP Aggregator, Orchestrator, Middleware, Gateway in one docker

Unique: Combines API key and OAuth authentication in a single system with per-endpoint and per-tool access scoping, persisted in PostgreSQL with audit logging. Supports both static API keys (for service-to-service) and dynamic OAuth tokens (for user-based access), enabling flexible multi-tenant deployments.

vs others: More flexible than API-key-only systems because it supports OAuth for user-based access, more granular than endpoint-level auth because it enforces tool-level access control, and more auditable than in-memory auth because all decisions are logged to persistent storage.

via “api-key-and-oauth2-authentication-gateway”

A simple, secure MCP-to-OpenAPI proxy server

Unique: Implements authentication as FastAPI middleware with pluggable validators, supporting both stateless API key validation and stateful OAuth 2.0 token introspection without requiring external API gateway infrastructure.

vs others: More integrated than reverse-proxy authentication because it has native access to request context and MCP server metadata; more flexible than hardcoded API key lists because it supports OAuth 2.0 federation.

via “api authentication and secure access”

Create and launch new tenants with admin setup and starter templates. Authenticate to securely access APIs and orchestrate external requests. Add document templates to existing tenants to standardize and scale your workflows.

Unique: Utilizes OAuth 2.0 and JWT for secure, token-based authentication, which is more flexible than traditional session-based methods.
