Phaedo — your cognitive fingerprint, on every AI surface

npm license

Phaedo learns how you think — communication style, working style, decision pattern — into a portable, user-owned cognitive fingerprint, and carries it to any AI tool. This repo is the open half of that system:

  • spec/ — Anamnesis (formerly "Phaedo Protocol"), the open cognitive-fingerprint standard: machine-readable JSON Schemas (fingerprint layers, consultation request/response, deference policies, receipts) + the conformance suite.

  • docs/protocol/ — the Anamnesis spec (v0.1), the MCP binding, and accepted proposals.

  • mcp/ — the reference MCP server (phaedo-mcp on npm): injects your fingerprint at session start and answers agent consultations — an agent at a decision point can ask "would my human proceed here?" and get a calibrated proceed / clarify / escalate / decline signal (or an honest abstain), gated by user-authored deference policies, with an encrypted on-device audit trail. On a blocking signal it can escalate to your paired phone in real time for a live approve / deny / modify, and your overrides teach the act-as-me channel — how you want delegated work handled, not just how you work yourself.

Quick start

Claude Code — install the plugin (it brings the server and the hooks):

claude plugin marketplace add phaedo-labs/phaedo-mcp
claude plugin install phaedo@phaedo

Claude Desktop — download desktop/phaedo.mcpb and double-click it.

Anything else that speaks MCP — npx phaedo-mcp runs the server over stdio.

Your full fingerprint comes from the Phaedo phone app, learned on-device from your actual usage. The app isn't open to the public yet (phaedo.so has a link to hear when it is). Without it, the Claude Code plugin builds a starter profile on your computer from your own sessions. With neither, the server says plainly that there is no profile; it does not guess. To try it with a made-up example profile, set PHAEDO_FINGERPRINT=sample. See plugin/README.md for what the plugin runs, stores and sends, and mcp/README.md for the full guide (pairing, policies, receipts, the agreement metric).

Design commitments

  • User-owned & local. The fingerprint lives on your devices, encrypted; the server holds no plaintext at rest. Nothing readable is sent to any Phaedo service: with a paired phone, messages between your computer and your phone are end-to-end encrypted, and the relay that carries them off your Wi-Fi can't read them.

  • Signals out, never structure. Consultations return a signal + confidence — never fingerprint internals (spec §10.4).

  • Honest abstention. No coverage → insufficient_signal, not a confident guess.

  • User-authored guardrails win. Deference policies (§10.5) override any inferred signal; standing authorizations are explicit and auditable (§10.6).

What's not in this repo

The learning pipeline that builds fingerprints (conversation capture, on-device extraction models) is Phaedo's proprietary side. This repo is everything a client, agent, or independent producer needs to consume and interoperate: the spec, the schemas, and a complete reference server.
