Set up

Add Serval to Cursor in four steps

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

  1. 1

    Add Serval to Runlayer

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

    Adding a connector manually
  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, Serval’s 402 tools show up in Cursor’s own tool list.

  3. 3

    Sign in to Serval

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

  4. 4

    Use Serval from Cursor

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

Tools

402 Serval tools in Cursor

Runlayer policy decides which of these Cursor users can call.

  • Add entity type field

    Deprecated: use POST /v2/entity-type-fields.

  • Add label to app instance

    DEPRECATED: use AddTagToSubject.

  • Add tag to subject

    Attach a tag to a subject (resource, role, app instance, workflow, or guidance).

  • Add ticket assignment group

    Add a group to the team's configured assignment groups.

  • Add ticket relevant asset

    Add a relevant asset to a ticket.

  • Aggregate entities

    Aggregate live-entity counts for one entity schema (database), grouped by entity type or by creation-time bucket (day or month).

  • Archive entity

    Archive an entity, hiding it from active browse while keeping its key reserved so the key cannot be reused.

  • Archive ticket

    Move a ticket into cold storage, removing it from most views.

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 Serval 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.
