Set up

Add Postman to Cline CLI in four steps

Admins approve the server once. Everyone in Cline CLI then gets it through the same governed connection.

  1. 1

    Approve Postman in Runlayer

    Add Postman from the catalog and choose who can use it and which of its tools are allowed.

  2. 2

    Connect Cline CLI to Runlayer

    Users add the Runlayer Plugin to Cline CLI by following Runlayer’s setup guide. Cline CLI reaches Postman’s 41 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Postman

    Sign in the way Postman requires. Runlayer holds the credentials so they stay out of the client’s configuration.

  4. 4

    Use Postman from Cline CLI

    Postman’s approved tools appear in Cline CLI. Every call is checked against policy and recorded.

Tools

41 Postman tools in Cline CLI

Runlayer policy decides which of these Cline CLI users can call.

  • Create collection

  • Create mock

    Creates a mock server in a collection.

  • Create spec

Control

What Runlayer can see and stop in Cline CLI

Some controls apply to every client at the gateway. Others depend on what Cline CLI exposes to Runlayer.

  • Gateway policy (available)

    Every Postman call from Cline CLI passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Cline CLI as the client, the tool, and the policy and scanner decisions.

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Cline CLI runs it.

  • Block output after it runs (not available)

    Cline CLI ignores Runlayer after a tool runs, so Runlayer cannot block its output. The gateway still applies policy to the call.

  • Redact output in place (not available)

    Runlayer cannot mask tool output in Cline CLI. The gateway still applies policy to the call.

In Cline CLI

  • If Runlayer’s hook times out or crashes, Cline CLI lets the tool call through.
  • This covers the Cline CLI, not the Cline extension for VS Code.
