Highstack

Highstack supports MCP servers over standard HTTP. Point your Highstack agent at AllMCP’s URL and API key, and your agent gains access to every provider you connect.

Connection

connection

MCP Server URL: https://go.allmcp.co/mcp/
Auth header:    X-API-Key: YOUR_API_KEY

Note

Works with any Highstack setup. Refer to the Highstack documentation for the exact config location and syntax — AllMCP works with any Highstack setup that accepts an MCP server URL and a custom header. If your setup only allows a bearer token, use Authorization: Bearer YOUR_API_KEY instead.

Per-user scoping

If you run Highstack for multiple end users, append ?user_id=<id> so each person connects and uses their own provider accounts:

per-user URL

https://go.allmcp.co/mcp/?user_id=USER_ID

Note

This keeps credentials separate — every user authorizes their own integrations, and one user never sees another’s data.

After connecting

1. See what’s available

   Ask your agent to list the available AllMCP integrations. It returns the catalog of providers and shows which ones you’ve already connected.

2. Connect a provider

   Ask your agent to connect the provider you want — for example, “Connect my Bitrix24” or “Connect Google Sheets.” AllMCP handles OAuth consent and token refresh for you; for OAuth providers your agent returns a link to approve in your browser, and for API-key providers you supply the credential when prompted.

3. Use the provider tools

   Once a provider is connected, its tools become available to your Highstack flows automatically. Just describe what you want — list contacts, update a deal, append a row — and your agent picks the right tool.
