+# ACP Mode
+
+ACP (Agent Client Protocol) mode is a special operational mode of Gemini CLI
+designed for programmatic control, primarily for IDE and other developer tool
+integrations. It uses a JSON-RPC protocol over stdio to communicate between
+Gemini CLI agent and a client.
+
+To start Gemini CLI in ACP mode, use the `--acp` flag:
+
+```bash
+gemini --acp
+```
+
+## Agent Client Protocol (ACP)
+
+ACP is an open protocol that standardizes how AI coding agents communicate with
+code editors and IDEs. It addresses the challenge of fragmented distribution,
+where agents traditionally needed custom integrations for each client. With ACP,
+developers can implement their agent once, and it becomes compatible with any
+ACP-compliant editor.
+
+For a comprehensive introduction to ACP, including its architecture and
+benefits, refer to the official
+[ACP Introduction](https://agentclientprotocol.com/get-started/introduction)
+documentation.
+
+### Existing integrations using ACP
+
+The ACP Agent Registry simplifies the distribution and management of
+ACP-compatible agents across various IDEs. Gemini CLI is an ACP-compatible agent
+and can be found in this registry.
+
+For more general information about the registry, and how to use it with specific
+IDEs like JetBrains and Zed, refer to the
+[IDE Integration](../ide-integration/index.md) documentation.
+
+You can also find more information on the official
+[ACP Agent Registry](https://agentclientprotocol.com/get-started/registry) page.
+
+## Architecture and protocol basics
+
+ACP mode establishes a client-server relationship between your tool (the client)
+and Gemini CLI (the server).
+
+- **Communication:** The entire communication happens over standard input/output
+  (stdio) using the JSON-RPC 2.0 protocol.
+- **Client's role:** The client is responsible for sending requests (e.g.,
+  prompts) and handling responses and notifications from Gemini CLI.
+- **Gemini CLI's role:** In ACP mode, Gemini CLI listens for incoming JSON-RPC
+  requests, processes them, and sends back responses.
+
+The core of the ACP implementation can be found in
+`packages/cli/src/acp/acpClient.ts`.
+
+### Extending with MCP
+
+ACP can be used with the Model Context Protocol (MCP). This lets an ACP client
+(like an IDE) expose its own functionality as "tools" that the Gemini model can
+use.
+
+1.  The client implements an **MCP server** that advertises its tools.
+2.  During the ACP `initialize` handshake, the client provides the connection
+    details for its MCP server.
+3.  Gemini CLI connects to the MCP server, discovers the available tools, and
+    makes them available to the AI model.
+4.  When the model decides to use one of these tools, Gemini CLI sends a tool
+    call request to the MCP server.
+
+This mechanism lets for a powerful, two-way integration where the agent can
+leverage the IDE's capabilities to perform tasks. The MCP client logic is in
+`packages/core/src/tools/mcp-client.ts`.
+
+## Capabilities and supported methods
+
+The ACP protocol exposes a number of methods for ACP clients (e.g. IDEs) to
+control Gemini CLI.
+
+### Core methods
+
+- `initialize`: Establishes the initial connection and lets the client to
+  register its MCP server.
+- `authenticate`: Authenticates the user.
+- `newSession`: Starts a new chat session.
+- `loadSession`: Loads a previous session.
+- `prompt`: Sends a prompt to the agent.
+- `cancel`: Cancels an ongoing prompt.
+
+### Session control
+
+- `setSessionMode`: Allows changing the approval level for tool calls (e.g., to
+  `auto-approve`).
+- `unstable_setSessionModel`: Changes the model for the current session.
+
+### File system proxy
+
+ACP includes a proxied file system service. This means that when the agent needs
+to read or write files, it does so through the ACP client. This is a security
+feature that ensures the agent only has access to the files that the client (and
+by extension, the user) has explicitly allowed.
+
+## Debugging and telemetry
+
+You can get insights into the ACP communication and the agent's behavior through
+debugging logs and telemetry.
+
+### Debugging logs
+
+To enable general debugging logs, start Gemini CLI with the `--debug` flag:
+
+```bash
+gemini --acp --debug
+```
+
+### Telemetry
+
+For more detailed telemetry, you can use the following environment variables to
+capture telemetry data to a file:
+
+- `GEMINI_TELEMETRY_ENABLED=true`
+- `GEMINI_TELEMETRY_TARGET=local`
+- `GEMINI_TELEMETRY_OUTFILE=/path/to/your/log.json`
+
+This will write a JSON log file containing detailed information about all the
+events happening within the agent, including ACP requests and responses. The
+integration test `integration-tests/acp-telemetry.test.ts` provides a working
+example of how to set this up.

+where agents traditionally needed custom integrations for each client. With ACP,
+developers can implement their agent once, and it becomes compatible with any
+ACP-compliant editor.
+
+For a comprehensive introduction to ACP, including its architecture and
+benefits, refer to the official
+[ACP Introduction](https://agentclientprotocol.com/get-started/introduction)
+documentation.
+
+### The ACP Agent Registry
+
+Gemini CLI is officially available in the **ACP Agent Registry**. This allows
+you to install and update Gemini CLI directly within supporting IDEs and
+eliminates the need for manual downloads or IDE-specific extensions.
+
+Using the registry ensures:
+
+- **Ease of use**: Discover and install agents directly within your IDE
+  settings.
+- **Latest versions**: Ensures users always have access to the most up-to-date
+  agent implementations.
+
+For more details on how the registry works, visit the official
+[ACP Agent Registry](https://agentclientprotocol.com/get-started/registry) page.
+You can learn about how specific IDEs leverage this integration in the following
+section.
+
+### IDE-specific integration
+
+Gemini CLI is an ACP-compatible agent available in the ACP Agent Registry.
+Here’s how different IDEs leverage the ACP and the registry:
+
+#### JetBrains IDEs
+
+JetBrains IDEs (like IntelliJ IDEA, PyCharm, or GoLand) offer built-in registry
+support, allowing users to find and install ACP-compatible agents directly.
+
+For more details, refer to the official
+[JetBrains AI Blog announcement](https://blog.jetbrains.com/ai/2026/01/acp-agent-registry/).
+
+#### Zed
+
+Zed, a modern code editor, also integrates with the ACP Agent Registry. This
+allows Zed users to easily browse, install, and manage ACP agents.
+
+Learn more about Zed's integration with the ACP Registry in their
+[blog post](https://zed.dev/blog/acp-registry).
+
+#### Other ACP-compatible IDEs
+
+Any other IDE that supports the ACP Agent Registry can install Gemini CLI
+directly through their in-built registry features.
