Model Context Protocol

Extend Warp’s agents with custom tools and data sources using MCP servers — modular plugins powered by a standardized interface.

Model Context Protocol (MCP)

MCP servers extend Warp’s agents in a modular, flexible way by exposing custom tools or data sources through a standardized interface — essentially acting as plugins for Warp.

MCP is an open source protocol. Check out the official MCP documentation for more detailed information on how this protocol is engineered.

In these docs, we'll focus on how to use MCP servers in Warp.

How to access MCP Server settings

You can navigate to the MCP servers page in any of the following ways:

• From Warp Drive: under Personal > MCP Servers

• From the Command Palette: search for Open MCP Servers

• From the settings tab: Settings > AI > Manage MCP servers

This will show a list of all configured MCP servers, including which are currently running

Adding an MCP Server

To add a new MCP server, you can click the + Add button. MCP server types you can add:

CLI Server (Command)

Provide a startup command. Warp will launch this command when starting up and shut it down on exit.

Adding a CLI MCP Server (Command)

Always set working_directory explicitly when your MCP server command or args include relative paths. This ensures consistent and predictable behavior across machines and sessions.

CLI Server (Command) MCP Configuration Properties

Property	Type	Required	Description
command	string	Yes	The executable to launch (e.g., npx).
args	string	Yes	Array of command-line arguments passed to command (e.g., module name, paths).
env	object	No	Key-value object of environment variables (e.g., tokens, API keys).
working_directory	string	No	Working directory path where the command is run, used for resolving relative paths. Default null
start_on_launch	boolean	No	Whether Warp auto-starts the MCP server on Warp launch. Default true

SSE Server (URL)

Provide a URL where Warp can reach an already-running MCP server that supports Server-Sent Events.

Adding an SSE MCP Server (URL)

SSE Server (URL) MCP Configuration Properties

Property	Type	Required	Description
url	string	Yes	The HTTP endpoint URL to connect to via Server-Sent Events (SSE).
env	object	No	Optional key-value object for environment variables or headers (e.g., tokens).
start_on_launch	boolean	No	Whether Warp connects to the SSE endpoint automatically on Warp launch. Default true

Adding multiple MCP Servers

Warp supports configuring multiple MCP servers using a JSON snippet. Each entry under mcpServers is keyed by a unique name (filesystem, github, notes, etc). All servers defined in the example are added automatically — no manual setup required. To add a multiple MCP servers, you can click the + Add button then paste in a JSON snippet like the example below.

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/files"],
      "start_on_launch": true
    },
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "your-github-token"
      },
      "start_on_launch": true
    },
    "notes": {
     "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-notes", "--notes-dir", "./notes"],
      "working_directory": "/Users/Warp/Documents",
      "start_on_launch": true
    }
  }
}

Managing MCP servers

After MCP servers are registered in Warp, you can Start or Stop them from the MCP servers page. Each running server will have a list of available tools and resources.

You can rename and edit a server's name, as well as delete the server. To prevent Warp from automatically starting a server when you open Warp, set the "start_on_launch" value to false in the server's JSON configuration.

Debugging

If you're having trouble with an MCP server, you can check the logs for any errors or messages to help you diagnose the problem by clicking the View Logs button on a server from the MCP servers page.

If you choose to share your MCP server logs with anybody, make sure to remove any sensitive information before sharing, as they may contain API keys.

Many SSE based MCP servers will state that your URL should be treated like a password, and can be used with no additional authentication.

Tip: We've noticed that some models often work better with MCP servers than others. If you're having trouble calling or using an MCP server, try using a different model.

Where MCP Logs Are Stored

Warp saves the MCP logs locally on your computer. You can open the files directly and inspect the full contents in the following location:

macOS

cd "$HOME/Library/Application Support/dev.warp.Warp-Stable/mcp"

Windows

Set-Location $env:LOCALAPPDATA\warp\Warp\data\logs\mcp

Linux

cd "${XDG_STATE_HOME:-$HOME/.local/state}/warp-terminal/mcp"
