🧠 MCP Server: Decisions

An open-source MCP server that helps teams record architectural decisions, connect them to testable predictions, and validate outcomes over time. It gives AI agents and developers a lightweight, auditable memory for technical choices.

✨ Project Highlights

  • Outcome-linked decisions — connect each technical choice to measurable predictions and observed results.
  • In-band outcome gates — tool responses identify predictions that still need validation before the work is considered complete.
  • Portable storage — append-only JSONL keeps the log inspectable, easy to back up, and free from database setup.
  • Zero runtime dependencies — Python's standard library is enough to run the server.
  • MCP-native interface — expose decision tracking through JSON-RPC over stdio to MCP-compatible clients.
  • Technology feedback — aggregate validated outcomes to inform future technology choices.

📌 What It Provides

The server exposes four tools:

Example flow

Decide → Predict → Implement → Measure → Validate → Learn

A decision can produce an outcome-gate reminder such as:

{
  "decision_id": "DEC-2026-0001",
  "status": "OK",
  "OUTCOME_GATE": "2 prediction(s) still lack outcomes."
}

The reminder is a workflow signal, not a claim about adoption or measured impact. See the Outcome Gate Pattern for the design and trade-offs.

📊 Current Project Status

The project is early-stage. Contributions, examples from real projects, and feedback are welcome.
