AllSource Prime with ChatGPT

Use Prime from ChatGPT desktop via its MCP connector — the same local stdio binary.

Prime runs as a local allsource-prime binary over stdio in ChatGPT. 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: Connector fields — Command / Arguments
Command:    allsource-prime
Arguments:  --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: Connector fields — Command / Arguments
Command:    allsource-prime
Arguments:  --data-dir ~/.prime/memory --auto-inject

Notes

Heads up: we couldn't fully verify ChatGPT's MCP config path against current vendor docs — it varies across versions. Double-check it in the client's settings, and read the notes below.
  • MCP connector support in ChatGPT is rolling out and gated by plan/region — availability and the exact Settings path differ across builds. If you don't see a local/stdio MCP connector option, use the Claude Code or Cursor page instead.
  • Enter the command and each argument as separate fields if the connector UI asks for an args array rather than one string.

After install

  • Restart ChatGPT 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.
