What is mtdata-mcp AGENTS.md?

Repository instructions for mtdata-mcp, a Python project with market-data services, forecasting and pattern tools, an API, reports, and a React web interface.

Use them when developing, testing, linting, evaluating schemas, or running the mtdata web application.

They explain where code belongs, which commands to run, and how to test and validate changes across the backend and web interface.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00709	$0.00709
Opus 5	$0.00354	$0.00354
Sonnet 5	$0.00142	$0.00142

Security

Grade A, and why

mtdata-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidelines

Project Structure & Module Organization

Python code lives in src/mtdata/. Runtime setup is in bootstrap/; CLI, MCP, Web API, reporting, regimes, and trading tools are in core/; market access belongs in services/; forecasting and pattern logic live in their named packages; shared schemas and utilities are in shared/ and utils/. The React/Vite client is under webui/src/. Keep tests in tests/, grouped by the corresponding domain (tests/core/, tests/services/, and so on). Documentation belongs in docs/, maintenance utilities in scripts/, and reusable agent prompts in prompts/.

Build, Test, and Development Commands

pip install -e ".[web,pattern-search-hnsw]" pytest ruff installs the backend and CI test tools for Python 3.14.
ruff check src tests runs Python lint and import-order checks.
python scripts/schema_evaluate.py validates public tool schemas.
python -m pytest tests runs the backend suite; pass a test path or -k expression for focused work.
mtdata-webapi serves the API and built UI locally.
From webui/, run npm ci, npm run dev, npm test, npm run typecheck, and npm run build to install, develop, verify, and package the frontend.

Coding Style & Naming Conventions

Use four spaces in Python, type hints on public interfaces, snake_case for modules/functions, and PascalCase for classes. Ruff rules in pyproject.toml are authoritative. Frontend code uses strict TypeScript, two-space indentation, PascalCase React components, and camelCase hooks/helpers. Preserve established single-quote, semicolon-free TS style.

Testing Guidelines

Pytest files and functions use the test_*.py / test_* pattern. Frontend tests use *.test.ts with Vitest. Add focused regression tests beside the affected domain and cover error paths and public contracts. No numeric coverage threshold is configured; all lint, schema, backend, frontend test, type-check, and build jobs must pass.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
