AllSource Prime with Windsurf

Windsurf's Cascade reads MCP servers from an mcp_config.json with the standard mcpServers envelope.

Prime runs as a local allsource-prime binary over stdio in Windsurf. 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: ~/.codeium/windsurf/mcp_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: ~/.codeium/windsurf/mcp_config.json

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

Notes

Heads up: we couldn't fully verify Windsurf'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.

Config path is the documented Windsurf default; open Windsurf → Settings → Cascade → MCP and click Refresh after saving, or edit the file via the 'View raw config' button if your version stores it elsewhere.
Windsurf uses the same `mcpServers` JSON shape as Claude Desktop — only the file path differs.

After install

Restart Windsurf 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.
