Catalogue/Agents/Open Multi Agent Core

Open Multi Agent Core

open-multi-agent · Agent

Open Multi-Agent, or OMA, is a self-hosted TypeScript agent runtime for backends. Give it one agent, an explicit task graph, or a goal that its coordinator turns into a workflow at runtime, and it schedules dependencies, runs independent work in parallel and shares context between agents. Tools are default-deny, consequential tool calls can wait for approval, runs can resume from checkpoints, and traces and evaluation sets are built in.

Written by ooruby from the README of @open-multi-agent/core 1.21.2.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

Agents run inside your own backend with approvals and inspectable run records, so you can see what they did.

What you could do with it

  1. 1Describe a goal and let the coordinator plan the tasks and assign them to a team of agents.
  2. 2Pause a tool call that has real consequences until a person approves it, then resume the run.
  3. 3Export an offline trace viewer to inspect how a run's tasks were scheduled.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

Not yet tested

How far this has been checked

Static scanned

What it establishes
Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not
How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read
Version 1.21.2, the file with digest sha512-/basd+p6NcjsqpR8OyUyNZH47QGsjrsaS4dEme6GDwkeLlf+1UEuebVBOB77uv3kQCJxyHxVPH76LofzhLH9mA==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
How the rungs work

Adding it

Run it with:

npx -y @open-multi-agent/core@1.21.2

Pinned to 1.21.2, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

The badge, if this is your listing

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
