Agent-protocol server registry

Every agent-protocol server worth knowing about, with the security and reliability data nobody else publishes.

AllACP catalogues agent-protocol servers with their full tool surface, required permission scopes, maintenance signals and an automated security grade. It is free to browse and free to list, and no one can pay to rank.

No account. No card. No sales call.

Search, filter and sort before you commit

Search, filter and sort example agent-protocol servers by category, hosting, price a month and rating. The entries are examples, not real agent-protocol servers. Runs in your browser. No account, no card, no call.

Example entries. These agent-protocol servers are made up to show how searching and filtering work. None is a real agent-protocol server, and nothing here has been checked.

What every registry entry shows

A living registry with an opinion, built so a developer can decide whether to trust a server from a single page.

The full tool surface

Each entry sets out what the server does and enumerates its tool surface in full.

Permission scopes required

See the permission scopes a server demands before you connect it.

Maintenance signals

Signals from the repository show whether a server is maintained or abandoned.

A security posture grade

An automated analysis grades each server's security posture.

Breaking-change history

A record of breaking changes, so you know what upgrading has cost others.

Queryable by API and by agents

The registry is queryable through an API and through an agent-callable interface.

The problem

A developer wanting an agent integration for a given service has no canonical place to look, no way to tell a maintained server from an abandoned one, and no signal about what permissions it demands or whether it has ever been audited.

Discovery happens through scattered lists that go stale in a month, and the security posture is entirely invisible.

Who it is for

  • Developers

    Developers choosing which agent-protocol servers to trust for an integration.

  • Security teams

    Teams building allowlists who need to see permissions and security posture.

  • Vendors

    Server vendors who need to be found, and who want their listing to show the work they have put in.

How it works

AllACP, from the first step to the result.

  1. 01

    Search the registry

    Find servers by the service you need to integrate.

  2. 02

    Check the entry

    Review the tool surface, permissions, maintenance signals and security grade.

  3. 03

    Query it programmatically

    Use the API or the agent-callable interface to build allowlists and tooling.

Questions people actually ask

What does each entry include?

What the server does, its tool surface enumerated in full, the permission scopes it requires, maintenance signals from its repository, a security posture grade from automated analysis, breaking-change history, and an uptime record for hosted endpoints.

Can vendors pay to rank higher?

No. There is no pay-to-rank, ever.

Does it cost anything to browse or list?

No. Browsing and listing are both free.

What do vendors pay for?

A verified vendor profile, at 199 dollars a month, adds analytics, lead capture and changelog syndication.

Can we use the data in our own tools?

Yes. API and bulk data access for security tooling companies is 990 dollars a month.

Can agents query it?

Yes. The registry is available through an agent-callable interface as well as an API.

Why should I trust the directory preview?

The entries shown are examples, not real agent-protocol servers, so use this to see how the search and filters work rather than to choose one.

Pricing

Free to browse and free to list. Vendors and security tooling companies pay for extras, never for ranking.
