+title: Agent Relay for Cursor
+---
+
+> [!NOTE]
+> Agent Relay for Cursor is in [early access](../../install/releases/feature-stages.md#early-access-features) and is currently in closed preview with select customers.
+
+[Agent Relay](./index.md) connects [Cursor Cloud Agents](https://cursor.com/cloud) to self-hosted Coder workspaces.
+Cursor also refers to this self-hosted worker model as [bring-your-own-machine (BYOM)](https://cursor.com/docs/cloud-agent/bring-your-own-machine).
+Developers keep using the Cursor client and cloud agent workflow they already know.
+The agent's tool calls run inside a Coder workspace on infrastructure you control instead of a Cursor-managed environment.
+
+Cursor's agent orchestration and AI inference remain cloud-hosted.
+Coder doesn't proxy or observe model inference.
+Coder provides the workspace where the agent executes, and logs that correlate the Cursor session and user to that workspace.
+
+## How it works
+
+1. A developer selects a Cursor worker pool mapped to a Coder organization and workspace template, then starts a Cursor agent session.
+1. Agent Relay claims the pending Cursor request and asks the Coder control plane to provision a workspace from the mapped template for that user.
+1. A Cursor worker process inside the workspace connects to the corresponding Cursor cloud session and executes the agent's tool calls.
+1. When the session ends, Agent Relay manages workspace teardown.
+
+Each Cursor agent session gets its own ephemeral workspace.
+

+title: Agent Relay
+---
+
+Agent Relay connects a cloud-hosted AI coding agent's hosted sessions to self-hosted [Coder workspaces](../../user-guides/workspace-management.md).
+Developers keep the cloud agent's client and workflow.
+Coder provides the workspace where the agent's tool calls run.
+
+## What Agent Relay does
+
+Agent Relay watches for pending agent sessions from a supported provider.
+When a session starts, Agent Relay provisions a Coder workspace from a mapped template and connects the session to a worker process inside that workspace.
+The worker executes the agent's tool calls, such as reading files, running commands, and using development tools, against the resources available in that workspace.
+Agent Relay manages the workspace for the life of the session and tears it down when the session ends.
+
+<img src="../../images/guides/ai-agents/agent-relay-stack.png" alt="Agent Relay architecture diagram" style="border: none;">
+
+## What Agent Relay is and isn't
+
+Agent Relay changes where a cloud agent's tool calls execute.
+It doesn't change where the agent's orchestration or AI inference run.
+Those stay with the cloud provider.
+
+Agent Relay is not:
+
+- A replacement for [Coder Agents](../agents/index.md), Coder's own AI workflow infrastructure that runs its native agent loop inside the Coder control plane and calls out to your configured LLM provider for inference.
+- A proxy or observability layer for a provider's AI inference.
+  Coder has no access to model selection or token usage for sessions that run through Agent Relay.
+- A self-hosted deployment of a cloud provider's control plane.
+  The provider's orchestration stays cloud-hosted.
+
+## Business value
+
+- Developers keep using the cloud agent client and workflow they already know.
+- Platform and security teams control the infrastructure where agent sessions execute and which internal resources those sessions can reach.
+- Agent sessions run in workspaces built from the same templates, networking, and governance controls as the rest of your Coder deployment.
+- Each session gets its own workspace, provisioned on demand and deleted when the session ends.
+
+## Current state
+
+Agent Relay is in [early access](../../install/releases/feature-stages.md#early-access-features) and is in closed preview with select customers.
+
+## Supported providers
+
+[Cursor](./cursor.md) is the first provider Agent Relay supports.
+Coder built Agent Relay to support additional cloud-hosted agent providers as they add support for self-hosted execution.
+
+## Get started
+
+If you want access to Agent Relay or want updates on the support status for your cloud-hosted agent provider of choice, talk to your [Coder account team](https://coder.com/contact) or email [sales@coder.com](mailto:sales@coder.com).

+Coder supports several ways to run and [govern](#govern-ai-activity-with-ai-governance) coding agents, depending on how much control you need over execution and orchestration:
 
-These agents work well inside existing Coder workspaces as they can simply be
-enabled via an extension or are built-into the editor.
+- [Coder Agents](#coder-agents), self-hosted AI workflow infrastructure best suited for headless, automated background tasks and parallel agentic development in a conversational UI.
+- [Agent Relay](#agent-relay), best suited for preserving the cloud agent experience developers already know while running execution in self-hosted Coder workspaces.
+- [Agents in the IDE](#agents-in-the-ide), best suited for in-editor code assist use cases alongside a developer's existing workflow.
+- [Agents in workspace templates](#agents-in-workspace-templates), best suited for developers who want to pair one-on-one with an agent like Claude Code or Codex in a workspace.

+Pick from a curated list of agent modules in the [template builder](../admin/templates/creating-templates.md#template-builder), or add a module directly in Terraform:
+
+```tf
+module "claude-code" {
+  source   = "registry.coder.com/coder/claude-code/coder"
+  version  = "~> 5.2"
+  agent_id = coder_agent.main.id
+}
+```
+
+Visit the [Coder Registry](https://registry.coder.com) for the full list of available agent modules.

 ## Govern AI activity with AI Governance
 
-AI coding tools are quickly becoming core to how engineering teams ship
-software. As adoption grows, platform teams want a clear picture of how AI is
-being used, consistent guardrails across teams, and predictable cost controls
-so they can confidently scale AI tooling to the whole organization.
-
-[AI Governance](./ai-governance.md) is included with a Premium license and adds
-observability, management, and policy controls for AI tooling across your
-Coder deployment. It includes:
-
-- [AI Gateway](./ai-gateway/index.md) for centralized authentication, audit
-  trails of prompts and tool invocations, and policy enforcement against
-  upstream LLM providers.
-- [Agent Firewall](./agent-firewall/index.md) for process-level network and
-  command policies that restrict what agents can reach and do inside a
-  workspace.
-[Learn more about AI Governance](./ai-governance.md) for use cases, entitlements,
-and how to enable it in your deployment.
