Set up

Add Fathom to Claude Code in four steps

Admins approve the server once. Everyone in Claude Code then gets it through the same governed connection.

  1. 1

    Add Fathom to Runlayer

    Fathom isn’t in the Runlayer catalog yet, so an admin adds it by its MCP server URL.

    Adding a connector manually
  2. 2

    Connect Claude Code to Runlayer

    Runlayer’s CLI installs the Runlayer Plugin natively in Claude Code, and an Anthropic org install also reaches Claude Code. With direct tool listing turned on for your deployment, Fathom’s 12 tools show up in Claude Code’s own tool list (supported Claude Code versions).

  3. 3

    Sign in to Fathom

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

  4. 4

    Use Fathom from Claude Code

    Fathom’s approved tools appear in Claude Code. Every call is checked against policy and recorded.

Control

What Runlayer can see and stop in Claude Code

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

  • Gateway policy (available)

    Every Fathom call from Claude Code passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Claude Code 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.

  • Anthropic inference hooks (available)

    With Claude Enterprise, Anthropic sends each governed Claude Code prompt to Runlayer before inference, with nothing installed on devices (Anthropic beta).

  • OTLP telemetry (available)

    Claude Code can export OpenTelemetry logs to Runlayer for observe-only session reconstruction.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Claude Code runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output before Claude Code’s model sees it.

  • Redact output in place (available)

    Runlayer can mask sensitive parts of a tool’s output in Claude Code and pass the rest through.

In Claude Code

  • When a tool fails, Runlayer records the error but cannot hide it.
