Security Report

6.2
Moderate6.2Moderate Risk

The MCP server implements a cognitive fingerprint protocol with reasonable security architecture. Authentication is absent by design (it operates over stdio and relies on process-level isolation), which is appropriate for an MCP server. The main concerns are moderate-severity code quality issues around input validation and error handling, combined with the sensitive nature of the data being processed (personal behavioral profiles). The server appropriately avoids exfiltration and unsafe operations, but input validation could be more comprehensive. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

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

npx phaedo-mcp        # run the server over stdio

Or wire it into Claude Desktop / Cursor / Claude Code automatically:

npm install -g phaedo-mcp
cd "$(npm root -g)/phaedo-mcp" && npm run setup

Out of the box it serves a sample fingerprint, so every tool works immediately. Your real fingerprint comes from the Phaedo app — currently in private beta (phaedo.so) — learned on-device from your actual usage; pair with npm run pair. See 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 is sent to any Phaedo service.
  • 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.
