MCP Server
This is an experimental feature. It may break or the interface may change.
Complete the connection steps below to give your agent of choice access to your Adnuntius account. Then ask it questions (for example about campaign performance, or fill rate) and it will suggest improvements based on data such as the latest traffic and reach forecasts available to your user. The agent has read only access to your account via a token which will refresh itself for 30 days, after which you will have to complete the authentication step again.
Register the Adnuntius MCP server with your agent
NOTE: If you are a user who has multiple networks, please select the network you wish to allow access to before pressing authorise in the steps below for your desired agent. Most users are in a single network and do not have to worry about this.
-> Anthropic Claude Code
Follow the 3 steps below to get setup with Claude Code.
1. Install a Client
You can skip this section if you already have a Claude Code client installed. The Adnuntius MCP is supported in both the App which you can get it from here:
Or the Command Line Interface (CLI) which you can get from here:
2. Install the Connector
Choose one of the 4 options below to do this. Option A is recommended.
Option A - Register to Account
The recommended approach is to add the Adnuntius connector to your claude.ai account which makes it available to all your clients.
If you are on a personal account you do that here:
Otherwise if you are an owner of a team account you do that here (if you are on a team account but not an owner, you must ask an owner to do this):
For either method, name the server what you like, and for the Remote MCP server URL use:
Once you press Add you (and everybody in your team if you have one) should see it in their list of connectors. You are now done with the setup and can use the MCP integration from the app or CLI. The following methods are only needed if you were not able to add the connector.
Option B - Register to CLI
The next step is only needed if you didn't follow the Register to Account instructions and wish to use the CLI. In that case you would add the Adnuntius MCP to the CLI client by running:
Option C - Register to Windows App
The following steps are only needed if you didn't follow the Register to Account instructions and you wish to use the app:
Go to the Connectors page in settings, and select Customize
Select + to add a new connector, and select ... Add custom connector
Name it whatever you like, and use the url https://api.adnuntius.com/api/mcp
Option D - Register to Mac App
There is currently no option to Add custom connector in the mac app, so the Adnuntius MCP can only be used in the Mac App via the Option A - Register to Account method.
3. Connect to Adnuntius
You connect the Claude Code App to Adnuntius by going to Settings -> Connectors -> Customise , selecting the Adnuntius connector (which is named depending on how you set it up in step 2), and clicking Connect:

If you are using the CLI, you connect to Adnuntius inside the CLI by typing /mcp and moving the selector down to adnuntius, pressing enter, and selecting 1. Authenticate
For either the app or CLI, you will then be taking to a page in your default browser which will ask you to authorise the agent to access your account (if you are not currently signed in to the Adnuntius Admin User Interface in that browser, you will be asked to sign in first). Once you click Authenticate, you should be connected in the app or CLI and can now ask questions from any session in it.
-> OpenAI Codex
1. Install the Codex Command Line Interface (CLI)
This is recommended even if you want to use the desktop app, because the app MCP has a number of bugs1 which make it unreliable to manage MCP servers in. The latest steps for installing the CLI can be found at:
omits the RFC 8707 resource= parameter so tokens get the wrong audience (#13891), sends a malformed /token exchange that fails with "Required argument is missing" (#5045), silently does nothing when DCR isn't supported and prints "No authorization support detected" in the CLI (#11585), can't reach its own localhost:1455 callback in Windows+WSL or other multi-namespace setups (#12263), and even when login succeeds the Desktop app still reports auth_status: "unsupported" and never imports the server's tools into threads (#20009)
2. Add the Adnuntius MCP Server and Authorize it
In a terminal, run
codex mcp add adnuntius --url https://api.adnuntius.com/api/mcp
This will open a browser window for you to complete the authentication by pressing the Authorize button. If you are not already signed in to the Adnuntius platform you will be asked to do so first.
3. Use codex to ask questions about Adnuntius
Type codexto start the CLI and start asking questions.
4. (Optional) Use the desktop app
This can be installed from here:
If you completed steps 1 and 2 above, you should be able to ask questions about Adnuntius in the app. If you didn't you can try and add the integration in the app using the following steps:
Go to the
MCP Serverpage in settings, and select+Add ServerSelect
Streamable HTTPand enterhttps://api.adnuntius.com/api/mcpas the URL. You can name the server anything you like.Back on the MCP servers page, an Authorize button should appear after about 10 seconds (otherwise click on the gear icon). This Authorize button will open your browser to complete the login flow.
-> Google Antigravity
If you haven't already, download the app from https://antigravity.google/download and install for your OS (Windows, Mac, or Linux are all fine)
If you haven't already, open the app, and in the setup select sign in with Google and complete the Google login in your browser
Exit the app and follow the OS specific setup instructions below
After completing the setup instructions below, open Antigravity again and click Settings (gear icon) → Customizations.
Scroll to Installed MCP Servers. You should see adnuntius with an "Unauthorized" warning.
Click Authenticate next to adnuntius. A browser tab will open to the Adnuntius admin page.
Sign in to Adnuntius if prompted, you should now be on a authorization page for token use.
Once you click Authorize google should give you an authorization code in your browser. Copy it.
Return to Antigravity. A dialog is waiting for the code, paste and click Submit.
The adnuntius row should turn green, and you can now ask the agent questions about your Adnuntius account
Google Antigravity OS specific setup instructions:
3a Windows Setup
In the start menu, search for Powershell and open it. Run the following command in it:
3b Mac Setup
In Launchpad, search for Terminal and open it. Run the following command in it:

Troubleshooting
Claude Code authentication or tool access issues
Go to https://claude.ai/customize/connectors and find the Adnuntius connector
Click the three dots in the top right and select
Refresh tools listIf there is a connection issue you should see a screen giving you a Connect button to re-authenticate
Once you press that button, after a short pause an Adnuntius window will open and you need to click the Authorize button to grant access
The window should close and claude.ai will display a message about being connected
After this you MUST restart your claude clients to pick up the new MCP auth, you cannot fix MCP state without a restart.
