One place that decides
what your AI can touch.

Your agents reach for data, tools, models, and each other. Right now every one of those reaches is granted ad hoc, with credentials pasted into whatever asked for them. MacroLinker is the control plane for all of it — authorize once, scope per agent, audit every action, cap the spend.

One object, five types.

A capability endpoint is anything an agent reaches for. A grant is who may reach it, how far, and for how much. The set of grants is your authorization graph — and that graph is the product.

Access control and spend control, over one graph.

Authorize once

A tool gets connected a single time, at the company level. Every agent inherits it — no re-running the same OAuth dance for the fifth agent that needs Slack.

Scope per agent

Your support agent reads tickets. It does not touch the warehouse. Grants are explicit, down to the individual tool an MCP server exposes.

Audit every action

One ledger of what was reached for, by which agent, when. Not a credential hand-off log — a record of what was actually done.

Cap the spend

Budgets per agent, per workspace, per endpoint. Attribution when the bill arrives, and a ceiling before it does.

One endpoint for every assistant.

Authorize your company’s tools once, then paste a single MCP endpoint into Claude, ChatGPT or Cursor. Every assistant your team already uses works from the same grants — and the same ledger.

It runs the other direction too: connect a provider’s own MCP server and its tools become governed capabilities like anything else, discovered rather than hand-written.

Adding a connector is a config entry, not a release.

Every connector ships with a real OAuth flow and a paste-a-credential fallback, so nothing is blocked waiting on an app registration. The provider's quirks — Zendesk needing a subdomain, Dropbox needing an offline token — live in one registry, not in each agent.

One app registration, not one per agent

Each provider is registered with MacroLinker once, for everything you run. Without that, every provider multiplies by every agent — a separate OAuth app to create, verify and maintain for each pairing.

Your agents plug in the same way

The Macro agents — MacroMkt, MacroPipe, MacroPrimer, MacroReply, MacroDeploy — are ordinary consumers of this API, with no privileged path. Anything you build connects on exactly the same terms.

Know what your agents can reach.

MacroLinker is being built now. If you are running agents against real company systems and can’t say which ones reach what, we want to talk to you.
