Connect Nimble to Gemini CLI

Give Gemini CLI governed access to Nimble’s 27 tools through Runlayer, with identity, policy, scanning, and audit on every call.

Set up

Add Nimble to Gemini CLI in four steps

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

  1. 1

    Approve Nimble in Runlayer

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

  2. 2

    Connect Gemini CLI to Runlayer

    Users add the Runlayer Plugin to Gemini CLI by following Runlayer’s setup guide. Gemini CLI reaches Nimble’s 27 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Nimble

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

  4. 4

    Use Nimble from Gemini CLI

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

Tools

27 Nimble tools in Gemini CLI

Runlayer policy decides which of these Gemini CLI users can call. 16 read data only and 5 can change or delete data.

  • Nimble crawl run

    Nimble Crawl: one-time bulk fetch of a known doc tree or URL list.

  • Nimble crawl status

    Check the status and progress of a running or completed crawl job.

  • Nimble crawl list

    List crawl jobs, optionally filtered by status.

  • Nimble crawl terminate

    Cancel a running or queued crawl job.

  • List extraction templates

    Browse Extraction Templates — reusable, site-specific structured scrapers.

  • Get extraction template

    Get an Extraction Template's input/output schema before running it.

  • Run extraction template

    Run an Extraction Template against 1–few known items (URL or site ID).

  • Generate extraction template

    Generate a new Extraction Template — only when the user explicitly asks to.

Control

What Runlayer can see and stop in Gemini CLI

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

  • Gateway policy (available)

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

  • Audit trail (available)

    Each call is recorded with the user, Gemini 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 Gemini CLI runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output before Gemini CLI’s model sees it.

  • Redact output in place (not available)

    Gemini CLI can only add text to a tool result, not replace it, so Runlayer blocks output it would otherwise mask. The gateway still applies policy to the call.

In Gemini CLI

  • Enforcement needs Gemini CLI 0.26.0 or newer.
  • When Runlayer blocks a call or its output, Gemini CLI shows the model the block reason instead.
