AllSource Prime with OpenCode

OpenCode uses its own envelope: a top-level `mcp` key, `type: "local"`, and command-as-array.

Prime runs as a local allsource-prime binary over stdio in OpenCode. 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: opencode.json
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "prime": {
      "type": "local",
      "command": [
        "allsource-prime",
        "--data-dir",
        "~/.prime/memory",
        "--auto-inject",
        "--sync-to",
        "https://api.all-source.xyz",
        "--api-key",
        "<YOUR_API_KEY>"
      ],
      "enabled": true
    }
  }
}

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: opencode.json
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "prime": {
      "type": "local",
      "command": [
        "allsource-prime",
        "--data-dir",
        "~/.prime/memory",
        "--auto-inject"
      ],
      "enabled": true
    }
  }
}

Notes

  • OpenCode's envelope differs from every other client: top-level `mcp`, `type: "local"`, and the command + all args go in ONE array.
  • Set `enabled: true` so OpenCode starts the server (it defaults to enabled, but being explicit avoids surprises).

After install

  • Restart OpenCode 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.
