Connect Claude, Cursor, Codex and ChatGPT to the Hedra MCP server

The Hedra MCP server is https://mcp.hedra.com. Add that URL to an MCP client and sign in with your Hedra account. The client can then generate video, images, speech, music and sound effects with every model in the catalog, read your Hedra library, and save what it makes there. You need no API key. Use your Hedra subscription or pay as you go; MCP settings in the developer console shows the workspace a client acts in and how Hedra bills its usage.

Add the server

Add Hedra to Claude

Add to Claude opens claude.ai’s Add custom connector dialog with the name Hedra and the URL https://mcp.hedra.com filled in. To add it by hand, open Customize → Connectors → Add custom connector and enter that URL.

Connect and sign in

Click Add, then Connect, and finish the Hedra sign-in.

claude mcp add --transport http hedra https://mcp.hedra.com

Run /mcp and complete the Hedra sign-in in the browser window it opens.

codex mcp add hedra --url https://mcp.hedra.com

Start Codex and approve the Hedra sign-in when it prompts you.

Add to Cursor installs the server. To add it by hand, put this in ~/.cursor/mcp.json:

{
  "mcpServers": {
    "hedra": { "url": "https://mcp.hedra.com" }
  }
}

Reload Cursor, then sign in to Hedra from the MCP panel.

Open Settings → Apps, add a custom app, and paste https://mcp.hedra.com. Some plans need developer mode on first. Then authorize Hedra.

Add this to ~/.hermes/config.yaml:

mcp_servers:
  hedra:
    url: "https://mcp.hedra.com"
    auth: oauth

Hermes opens the Hedra sign-in and keeps the token after the OAuth callback.

Try it

Ask the client:

Use Hedra to make a hero image for a coffee brand landing page, 16:9, moody morning light

The client submits the job and shows the image when it finishes. Ask for a video, a voice or a song the same way, or name a model from the catalog.

If the client reports 404

The server URL is https://mcp.hedra.com on its own. A connector saved with a curl command, or with an api.hedra.com URL, gets 404 from every chat that uses it. Remove that connector and add the URL above. The REST API at api.hedra.com is for code you write, with an API key; the quickstart covers it.
