AllSource Prime with Codex
OpenAI's Codex CLI reads MCP servers from ~/.codex/config.toml under an [mcp_servers] table.
Prime runs as a local allsource-prime binary over stdio in Codex. 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-prime2. 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.
One click mints a Prime-scoped key. We don't show secrets twice — paste it into the config below.
Then paste this, swapping <YOUR_API_KEY> for the key you just minted:
[mcp_servers.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.
[mcp_servers.prime]
command = "allsource-prime"
args = ["--data-dir", "~/.prime/memory", "--auto-inject"]Notes
- Codex CLI uses TOML, not JSON, and the table is `mcp_servers` (snake_case).
- Run `codex mcp list` (where available) to confirm Prime registered after editing the file.
After install
- Restart Codex 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.
