AllSource Prime with Claude Desktop

The original Prime surface — paste one JSON block, or double-click the .dxt bundle for a no-terminal install.

Prime runs as a local allsource-prime binary over stdio in Claude Desktop. The same store serves every MCP client you wire it into — one source of truth, everywhere your agents work.

1. Install the binary

From crates.io. Builds standalone — no AllSource server required, just a Rust toolchain.

cargo install allsource-prime

2. Hosted memory (recommended)

Mint an API key, then run Prime with --sync-to. Your memory persists to your AllSource tenant and shows up live in the dashboard — and the same key works from any other client you connect.

Mint your API key

One click mints a Prime-scoped key. We don't show secrets twice — paste it into the config below.

Get API key

Then paste this, swapping <YOUR_API_KEY> for the key you just minted:

Paste into: claude_desktop_config.json

{
  "mcpServers": {
    "prime": {
      "command": "allsource-prime",
      "args": [
        "--data-dir",
        "~/.prime/memory",
        "--auto-inject",
        "--sync-to",
        "https://api.all-source.xyz",
        "--api-key",
        "<YOUR_API_KEY>"
      ]
    }
  }
}

3. Local-only alternative (no account)

Skip the account entirely. Drop the --sync-to / --api-key flags and memory stays on disk at ~/.prime/memory. Nothing leaves your machine.

Paste into: claude_desktop_config.json

{
  "mcpServers": {
    "prime": {
      "command": "allsource-prime",
      "args": [
        "--data-dir",
        "~/.prime/memory",
        "--auto-inject"
      ]
    }
  }
}

Notes

Easiest path: download the `.dxt` bundle from the latest GitHub release and double-click it — Claude Desktop prompts for your API key and writes the config for you.
Fully quit and relaunch Claude Desktop (not just close the window) after editing the config.
On macOS, Claude Desktop may need Full Disk Access for data dirs outside your home folder.

After install

Restart Claude Desktop so it picks up the new MCP server.
Verify by asking it: "List the MCP tools you have available." You should see prime_add_node, prime_recall, and friends.
On the hosted path, watch nodes appear live at /dashboard/memory.
