Connect any AI stack

Hiasynth is a remote MCP server, so anything that speaks MCP over HTTP can use it: Le Chat, Cursor, LibreChat, or an agent you're building yourself. Three steps, whatever the stack. Building something of your own? Build with Hiasynth is the full reference.

  • Subscribe from the home page you land on. Connecting and browsing the catalogue is free before that; answers need the subscription.
The Hiasynth home page after signing in: plan, credits, and the way to the connector

Your home page: plan, credits, the server address and API keys in one place

Add the server to your client

Add a remote MCP server (some clients say connector, or integration). The transport is streamable HTTP, and this is the only address, for every client and every plan:

https://mcp.hiasynth.co

Sign in, or send a key

  • Clients that can open a browser (Le Chat, Cursor and most others): click Connect, sign in on the Hiasynth page that opens, approve. No key to copy.
  • Clients that can't (scripts, cron jobs, LibreChat, your own agent): create an API key on your connector page and send it as a bearer token on every request. The key is shown once.
Authorization: Bearer YOUR_API_KEY

In a client configured with JSON, that looks like this:

{
  "mcpServers": {
    "hiasynth": {
      "url": "https://mcp.hiasynth.co",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Then ask:

How many households in Bavaria have children under ten and an electric car, and where are they densest?

Keys and connected clients can both be revoked from your connector page at any time.
