Set up

Add Sentry to Cursor in four steps

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

  1. 1

    Approve Sentry in Runlayer

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

  2. 2

    Connect Cursor to Runlayer

    Runlayer’s CLI installs the Runlayer Plugin natively in Cursor, and admins can roll it out org-wide with Auto Sync plus a Cursor team rule. With direct tool listing turned on for your deployment, Sentry’s 16 tools show up in Cursor’s own tool list.

  3. 3

    Sign in to Sentry

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

  4. 4

    Use Sentry from Cursor

    Sentry’s approved tools appear in Cursor. Every call is checked against policy and recorded.

Tools

16 Sentry tools in Cursor

Runlayer policy decides which of these Cursor users can call. 4 read data only.

  • Analyze issue with seer

  • Execute Sentry tool

  • Find dropped events

    Find events dropped before they were stored in Sentry — ground-truth data-fidelity information about what was and wasn't captured.

Control

What Runlayer can see and stop in Cursor

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

  • Gateway policy (available)

    Every Sentry call from Cursor passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Cursor 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 Cursor runs it, including calls to MCP servers.

  • Block output after it runs (available)

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

  • Redact output in place (not available)

    Cursor cannot take masked output, so Runlayer can block a tool’s output but not mask it. The gateway still applies policy to the call.

In Cursor

  • Runlayer cannot tell Agents Window sessions apart from regular IDE sessions.
  • The Cursor CLI sends fewer session events than the IDE, but Runlayer’s allow and deny decisions still apply.
