Agents know how.Roster resolves who.
A Participant Resolution Agent providing the organizational harness for AI workflows. Roster resolves natural language queries down to the right active users, groups, and roles using your existing directory data.
Built on the routing & delegation engine that Advantys has run in production for 20+ years




















One agent. Every surface.
Expose every capability via MCP tools, CLI, REST API, and web UI for seamless integration with any AI toolchain or agent ecosystem.
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.
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
Instant deployment
One Docker container. No database, no extra infrastructure. Runs on-prem, in private cloud, or public cloud — wherever your agents already are.
Flexible access
Reach the same resolution agent from anywhere: MCP, CLI, REST, and a modern web platform. One source of truth across your AI toolchain.
Decentralized control
Project Owners independently manage their projects, participants, and delegations — no central admin bottleneck, no IT tickets.
Core capabilities
