X

Before you begin, obtain:

• An X account that can enroll in the X Developer Platform and accept the Developer Agreement and Policy.
• Authority to create an X developer app.
• Organization-approved wording for the app name, description, and API use case.
• Access to your organization’s password manager or secure vault.
• API credits available through the billing and credits area of the Developer Console. API requests are blocked when the credit balance is zero or negative.

This setup provides read-only access to public data. It cannot act as a user or perform writes.

Enroll in the X Developer Platform

1. Go to console.x.com.
2. Sign in with the X account that will own the developer app.
3. If prompted, review the Developer Agreement and Policy.
4. If prompted, accept the Developer Agreement and Policy.
5. Provide the requested information about how your organization will use the API. Obtain the wording from the application or cloud security owner if needed.
6. Complete the remaining enrollment steps shown in the console.

Successful enrollment opens the Developer Console dashboard. Confirm that New App is visible.

Create an X app

1. On the Developer Console dashboard, select New App.
2. Enter the organization-approved app name, description, and use case.

Before you submit the form, open your organization’s password manager or secure vault. X displays generated credentials once.

3. Submit the form using the create control shown in the console.

X creates the app and displays its credentials, including the Bearer Token.

Copy the Bearer Token

Copy Bearer Token from the generated credential view into your organization’s password manager or secure vault before leaving the page.

Add the server in Speakeasy

In the Speakeasy AI Control Plane sidebar, under Connect, select Sources, then click Add Source.

• If X is in the catalog: choose 3rd-party server. On the MCP Catalog page, find X (the search box reads Search MCP servers…), open its entry with View, and click Add. If the Add to Project dialog requests headers during installation, configure its Upstream headers section before continuing — follow steps 3–6 under Connect your credentials. In the Add to Project dialog, click Add to Project.
• If it is not: choose Custom remote server. On the Add a custom remote MCP server page, paste https://api.x.com/mcp into Remote MCP server URL and click Add server.

Either path creates the hosted MCP server and opens its Overview page.

Connect your credentials

If you configured headers in the Add to Project dialog, skip this section. Otherwise, from the server’s Overview page:

1. Open Settings.
2. Under Upstream Headers, select Add header.
3. Enter Authorization in Header name.
4. Leave Value source set to Static value.
5. In the value field, enter Bearer followed by the Bearer Token you saved.
6. Select Secret.
7. Select Save.
