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.
