One neutral primitive between your agents and your directory.

Every agentic workflow eventually asks who needs to act, approve, or be notified next? Instead of hard-coding org logic into each tool, your callers reach Roster over any surface — and Roster resolves it against the data you already have.

01

An agent sends a plain-language query.

From an MCP client, orchestration platform, automation runtime, or AI dev tool — over any surface it already speaks.

One neutral primitive on the protocol surface. It parses the intent and resolves who — no directory logic baked into the caller.

Resolved against the directory you already run.

Live org structure, active accounts, roles and delegations — read from the source of truth you already maintain. Nothing duplicated.

The right active users, groups, and roles.

A precise, current answer the agent can act on — approve, notify, escalate, or route — without ever hard-coding an org chart.

Designed for frictionless engineering & edge ownership

One Docker container. No database, no extra infrastructure. Runs on-prem, in private cloud, or public cloud — wherever your agents already are.

Decentralized control

Project Owners independently manage their projects, participants, and delegations — no central admin bottleneck, no IT tickets.
