io.github.FlawlessBytePublished by GitHub account FlawlessBytev0.1.0Updated Oct 24, 2026
Paper-backed quant trading methods and a deterministic, no-LLM decision helper for serious traders.
Overview
A local MCP server giving an assistant paper-backed quantitative trading methods and a deterministic scoring helper for screening, signals and entry decisions.
- What you can do
- List and describe the bundled trading methods with their paper citations, and extend the registry with new ones from code modules. Screen a ticker universe and compute indicators such as EMA, RSI, ATR, VWAP and Hurst. Detect market regime and run per-ticker or universe methods to get signals with entry, stop and target levels. Backtest a method over history with win rate, expectancy, drawdown and in-sample versus out-of-sample halves. Check earnings and ex-dividend events, portfolio heat and correlation, and broad market context with sectors and VIX. Score a setup deterministically into a verdict, position size and execution plan, and fetch recent headlines for the agent to interpret.
- When to use it
- Useful for traders or researchers who want an assistant to run reproducible quantitative screening, method signals, backtests and risk checks on US equities, with the assistant supplying narrative and sentiment judgement. Not intended for placing orders or as investment advice.
- Requirements
- Runs as a local stdio process; install via uvx from PyPI or GitHub, pipx, Docker, or from source with git and uv. Python-based; the Claude Desktop bundle still needs uv on the machine. Network access is needed for most tools, which use yfinance by default with roughly 15-minute delayed data. An alternative data provider can be selected with the QUANT_DATA_PROVIDER environment variable.
Installation
In SourceWeft
- Open Quant Research MCP in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

[CI] [License: MIT] [Python] [MCP]
An MCP server exposing a registry of paper-backed quantitative trading methods
plus a deterministic, no-LLM decision helper. The server supplies reproducible
math (screening, indicators, regime detection, method signals, scored entry
decisions); the calling agent supplies judgement (e.g. reading headlines into a
sentiment signal). No claude -p, no subprocess, no LLM inside the server.
⚠️ Not financial advice. This is read-only research and educational tooling. It performs quantitative computation only and places no orders. Nothing it outputs is investment advice or a recommendation. Market data may be delayed or wrong, backtests are not forecasts, and trading carries substantial risk of loss. You alone are responsible for any capital you risk. Provided "as is" without warranty — see
LICENSE.
Why this exists
Repackages a working day-trading pipeline as composable MCP tools, with two goals:
- Extensible to future papers. Each strategy is a
TradingMethodregistered in a registry. Adding a new paper = drop one module, callregister(...), import it. Nothing else changes. - Decision-making is scientific, not generative. The old pipeline gated entries
with an LLM call. Here that is replaced by
quant_score_decision— a pure function combining reward:risk, regime strength, volume, RSI positioning and ATR-normalised stop quality into an auditable score. Same inputs → same output.
Tools (13)
All tools are read-only and support response_format: markdown | json.
Workflows
Day trade
Swing (days) — rsi2_reversion, pairs_cointegration via
quant_analyze_setup / quant_analyze_universe; earnings veto matters most
here (quant_check_events → days_to_earnings).
Position (weeks+) — donchian_trend per ticker, xs_momentum over the
universe; re-rank monthly, weekly stop review per the execution plan.
Before trusting any method: quant_backtest_method on your tickers and
period — it replays the method's own signal logic with costs, and reports
in-sample vs out-of-sample halves so you can see decay.
The agent writes any narrative; the server guarantees the numbers.
The decision helper (quant_score_decision)
Pure function. Composite score (weights in config.DECISION_WEIGHTS):
- reward_risk — realised R:R vs the target multiple.
- regime_strength —
|Hurst − 0.5|scaled (distance from random walk). - volume_confirmation — relative volume vs the floor.
- momentum_position — RSI in a healthy band for the direction (not exhausted).
- stop_quality — stop distance normalised by daily ATR (noise-tight stops penalised).
Optional news_sentiment (the agent derives this) boosts an aligned score or
vetoes a contradicted one at confidence ≥ 0.5. Output includes the per-factor
breakdown, fixed-fractional position_size (with a haircut for noise-tight stops),
and a mechanically derived execution_plan (entry trigger, order type, stop ladder,
profit taking, time stop, abort conditions).
Bundled methods (5)
Data providers
Default is yfinance (free, ~15-min delayed). The data layer sits behind a
provider interface (quant_research_mcp/providers/): implement the
DataProvider protocol for Alpaca/Polygon/IBKR, register the factory, then run
with QUANT_DATA_PROVIDER=<name>. All calls are TTL-cached in-process (daily
15 min, intraday 60 s, news 5 min, events/sector 1 h).
Adding a future paper
Then add from . import my_paper to methods/__init__.py. It now appears in
quant_list_methods and is runnable via quant_analyze_setup(method_key=...).
Quick start (Makefile)
Install as a shell binary
If the command isn't found after install, run uv tool update-shell and restart
your shell (uv's tool bin dir, usually ~/.local/bin, must be on PATH).
Install
Every method runs the same stdio server — pick whichever fits your setup.
PyPI and Docker images are published on tagged releases; until the first release, use the uvx from GitHub or from source rows.
Use with Claude Code
Fastest — runs straight from GitHub, no clone:
After a PyPI release this shortens to:
Containerised:
From a local clone (development): make claude-add registers this checkout at
user scope; make register prints a paste-ready .mcp.json block.
Verify inside Claude Code:
Then ask e.g. "screen the universe and analyze the top name with the hurst
method, then score the entry decision." It will call quant_screen_universe
→ quant_analyze_setup → quant_score_decision.
From source (development)
Optional: make install-cli puts a quant-research-mcp binary on your PATH
(via uv tool). If it isn't found afterwards, run uv tool update-shell and
restart your shell. Inspect tool schemas with make inspect.
Releasing (maintainers)
CI runs ruff + the 40 offline tests on every push/PR (Python 3.12 & 3.13). Cutting a release is tag-driven:
That fires two workflows:
release.yml→uv build, publish to PyPI via Trusted Publishing (OIDC, no stored token), and attach the wheel/sdist + a.mcpbbundle to the GitHub Release.docker.yml→ build and pushghcr.io/flawlessbyte/quant-research-mcp.
One-time setup:
- PyPI: create the project and add a Trusted Publisher (owner
FlawlessByte, repoquant-research-mcp, workflowrelease.yml, environmentpypi). - GHCR: after the first push, set the package visibility to public.
- MCP registry: after the first PyPI release, list it with the
mcp-publisherCLI —mcp-publisher login githubthenmcp-publisher publish(usesserver.json; GitHub login proves ownership of theio.github.FlawlessByte/…namespace).
The Claude Desktop
.mcpbinvokesuvxunder the hood, so a one-click install still requires uv on the machine — bundling pandas/scipy/statsmodels wheels directly would be large and platform-specific.
Limitations (what a serious trader still needs elsewhere)
- Delayed data until you wire a real-time provider key (interface is ready; yfinance is ~15-min delayed and its news feed is thin).
- No macro calendar (FOMC/CPI/NFP) — no reliable free feed; pass your own
judgement through
news_sentiment/news_confidence. - No options data (IV, term structure, gamma levels), no short interest/float, no Level 2 — next frontier.
- Backtests are parameter validation, not forecasts: yfinance history has survivorship bias, costs are estimates, intraday replay is capped at ~60 days of 5m bars by the provider.
- No persistence by design — the server stores nothing; supply open
positions per call (
quant_portfolio_risk). A trade journal is a planned opt-in module.
