L2MThe MCP-native agent runtime

Visual workflow builder, multi-agent Swarm, and a VS Code surface — for developers composing AI agents that do real work in real systems via the Model Context Protocol.

Why L2M?

GitHub

MCP-first

Wire any Model Context Protocol server in as an agent tool. Schemas are compacted, tools are shortlisted by prompt relevance, and full outputs are cached across multi-turn sessions. Expose your own workflows back out as MCP tools that other agents invoke.

Multi-agent Swarm

Compose Supervisor → Worker hierarchies via dedicated attachment ports. Workers become synthetic tools to the parent, recursively. Other visual workflow tools either lack MCP integration entirely or treat agent delegation as chained prompts rather than first-class topology.

VS Code agent surface

First-party extension turns any workflow into a coding agent inside the editor — streaming responses, patch previews with workspace-path safety, and command approval. Bring your own backend agent topology.

Production-ready foundations

SAML/LDAP SSO, MFA, encrypted secrets with rotation, external secret managers (Vault/AWS/GCP/Azure), RBAC + projects + custom roles, audit logs, Prometheus, OTEL tracing, and multi-main HA via leader election.
