Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Evidence-backed decision briefs with citations — recommendation, confidence, risks, sources.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
QUREDEC_API_KEY, QUREDEC_BASE_URL, QUREDEC_MOCKValues marked secret are keys to your account. Never share them or paste them into a chat.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Run a structured QuReDec decision brief from inside Claude Code, Claude Desktop, Cursor, or any MCP-compatible client.
Status: alpha (2026-04-30). Wired to the live QuReDec public API
(
/api/v1/brief*, per-user Bearer-token auth). SetQUREDEC_MOCK=1for
offline development.
| Tool | Description |
|---|---|
decision_brief | Submit a question; receive a structured, evidence-backed decision brief with citations |
get_brief_status | Poll an in-progress brief by ID |
list_recent_briefs | List the caller's recent briefs |
The completed brief contains: executive_summary, recommendation, confidence (0–1), key_facts[].citation_ids, implications[], actions[] (with effort + impact), risks[] (with severity + citation_ids), and citations[] (with citation_id, title, url, source_type).
pip install quredec-mcp
Or from source:
git clone https://github.com/Advanced-Binary-Operations/QuReDec_MCP
cd QuReDec_MCP pip install -e .
Generate a QuReDec API key at https://quredec.com/account → API keys. Each key is shown to you exactly once at creation; copy it into a password manager immediately.
Add to your MCP client config (Claude Desktop example):
{
"mcpServers": { "quredec": { "command": "quredec-mcp", "env": { "QUREDEC_API_KEY": "qrd_live_xxxxxxxxxxxx" } } } }
Optional env vars:
QUREDEC_BASE_URL — defaults to https://quredec.com.QUREDEC_MOCK=1 — run against an in-process mock for development.In Claude Code or Claude Desktop:
Use the
decision_brieftool to evaluate "Should I migrate from Stripe to LemonSqueezy?"
The brief comes back with: recommendation, confidence score, key facts with inline citation ids, risks, recommended actions, and a public share URL. Briefs typically take 2–5 minutes; the tool blocks and polls by default (timeout 600 s) and falls back to a synthetic running status with a poll hint if the timeout fires.
The MCP server is free. Briefs consume credits from your QuReDec account:
See https://quredec.com/pricing.
Unit tests run against the in-process mock (no network, no key required):
pip install -e ".[dev]"
QUREDEC_MOCK=1 pytest
Run the server locally against the mock:
QUREDEC_MOCK=1 quredec-mcp
scripts/integration_test.py exercises the full path against quredec.com: submit → poll → assert brief schema → list. It consumes 1 credit from the account whose key you pass in, so run it sparingly.
QUREDEC_API_KEY=qrd_live_xxxxxxxxxxxx \
python scripts/integration_test.py
Optional env vars:
QUREDEC_BASE_URL — defaults to https://quredec.com.QUREDEC_QUESTION — override the default seed question.QUREDEC_TIMEOUT — poll timeout in seconds (default 600).Exit code 0 on full pass, 1 on the first failed assertion.
