typesafe-mcp
An MCP server exposing TypeSafe evaluation to coding agents.

- Problem
- An MCP server exposing TypeSafe evaluation to coding agents.
- Jev’s role
- Machine-readable decisions and probabilities available as agent tools.
- Architecture
- MCP client → server tool → TypeSafe API → typed response.
- Why it matters
- The probability-bearing result can be preserved through agent infrastructure instead of flattened to prose.
Code boundary
Jev answers the bounded questions described above. Thresholds, retries, side effects, and anything that must be reproducible stay in the surrounding application code. The research record does not capture this project’s exact question set or threshold values; read the linked source before copying the architecture.

Limitations
- A located repository or demonstration does not establish production reliability or independent validation.
Reusable pattern and related records
- Decision quorum PlausibleMultiple typed judgments are aggregated through voting or confidence-aware stopping.
- Agent Tool Firewall Authored HypothesisA local gateway that scores every proposed tool call and requires confirmation only when risk is high.
- Jev exposes constrained decision primitives for Boolean probability, choice distributions, and ordered scores. DemonstratedThe public API documentation defines `noul`, `choice`, and `score` response shapes.
- Decision sidecar PlausibleA typed judgment service sits beside ordinary code; code owns effects and safety boundaries.
