Connect Collate to Codex
Give Codex governed access to Collate’s 19 tools through Runlayer, with identity, policy, scanning, and audit on every call.
Set up
Add Collate to Codex in four steps
Admins approve the server once. Everyone in Codex then gets it through the same governed connection.
- 1
Add Collate to Runlayer
Collate isn’t in the Runlayer catalog yet, so an admin adds it by its MCP server URL.
Adding a connector manually - 2
Connect Codex to Runlayer
Runlayer’s CLI adds the Runlayer Plugin to Codex’s local plugin marketplace, and users then enable it in Codex. With direct tool listing turned on for your deployment, Collate’s 19 tools show up in Codex’s own tool list (Codex 0.122 or newer, installed through the Runlayer CLI).

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

Control
What Runlayer can see and stop in Codex
Some controls apply to every client at the gateway. Others depend on what Codex exposes to Runlayer.
Gateway policy (available)
Every Collate call from Codex passes through Runlayer, where your policies can allow, alert, mask, or block it.
Audit trail (available)
Each call is recorded with the user, Codex 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 or permission request before Codex runs it.
Block output after it runs (available)
Runlayer can block a tool’s output before Codex’s model sees it.
Redact output in place (not available)
Codex cannot take masked output, so Runlayer can block a tool’s output but not mask it. The gateway still applies policy to the call.
