Weaveloop

Fine-grained permissions for the APIs and MCPs your AI agents use.

Get Started

Give your AI agents exactly the access they need

Most APIs only offer coarse permissions: read everything, or read, write, and delete everything. Weaveloop sits between your accounts and your agents so you can compose custom MCPs from individual capabilities and resources.

Why Weaveloop?

  • Scope by resource, not by account. Let an agent read one calendar and write to a different one, instead of granting full access to all of them.
  • Scope by capability. Give an agent permission to read a single email folder and create drafts, with no ability to send or delete.
  • One connection, many agents. Connect an API or MCP to Weaveloop once, then build as many purpose-built MCPs on top of it as you need.

How It Works

  1. Connect. Link your APIs and MCPs to Weaveloop using their standard OAuth or API credentials.
  2. Compose. Build a custom MCP by picking the exact capabilities and resources an agent should have.
  3. Hand it off. Point your AI agent at the custom MCP. It can only do what you composed, nothing else.
