What is the Phaedo MCP Server?

Phaedo carries a local preference projection into assistants and offers consultation tools at selected decision points.

Carry preferences across clients

Phaedo exposes a projection of the user's cognitive fingerprint to a compatible assistant. The documented tools request that projection, consult a decision pattern and check authorization context. This is a personalization interface, rather than a general-purpose approval system. Inspect the actual projection and policy before allowing its results to influence an automated workflow.

Local stdio package

The npm package phaedo-mcp runs over stdio. A local JSON fingerprint can be supplied with PHAEDO_FINGERPRINT; the project also documents pairing with its phone application. Consultation can use a configured model endpoint, with additional model, URL and API-key settings. The standard local mode is implemented, while the enhanced privacy transport is described as future work.

Test a decision with a sample projection

Use a non-sensitive sample fingerprint, request its injection and ask a consultation question with a known context. Compare the answer with the supplied preferences and inspect any local consultation receipt. Pairing and projection access follow the application's authorization flow. Preferences should inform a decision, while permission to take an external action should remain explicit in the workflow using the tool.
