metorial
AI agentsMetorial (YC F25) is an open-source identity and access layer tool for AI agents. It acts as a control plane between agents and external systems, handling authentication, permissions, and observability in a unified way. It supports connections to over 1,200 integrations (covering SaaS tools, enterprise systems, data sources, and custom MCP servers), provides lifecycle management for credentials such as OAuth, API keys, and service accounts, and includes built-in RBAC, SAML SSO, IAM, and fine-grained permissions scoped by agent, workflow, team, or environment. Metorial can log and audit agent actions, tracing which agent performed an action using whose credentials. For developers, it provides a unified API and connection URL that can seamlessly integrate with Claude Code, Codex, Cursor, and various agent frameworks (such as Vercel AI SDK, OpenAI, Anthropic, LangChain, LangGraph, LlamaIndex, AutoGen, CrewAI, etc.). The platform itself is open source and self-hostable, while also offering a hosted platform option.
