snowflake-mcp-server CLAUDE.md

snowflake-mcp-server CLAUDE.md is an instructions file for coding agents from dynamike/snowflake-mcp-server. It costs 293 tokens per session, scanned A, original, MIT.

A project instruction file for a Python server that connects to Snowflake, a cloud database used for storing and querying data. It documents setup, running the server, tests, linting, formatting, type checking, and coding rules.

In plain words
What is it for?
Use it as a reference when installing dependencies, starting the server, running pytest, checking coverage, using Ruff or mypy, and writing safe Snowflake queries.
Why use it?
It gives coding agents consistent project-specific directions for building, testing, and modifying the server.

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.

Security

Grade A, and why

snowflake-mcp-server CLAUDE.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 4d 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.

What it actually says

CLAUDE.md - MCP Server Snowflake (Python)

Build & Run Commands

  • Setup: uv pip install -e . or uv pip install -r requirements.txt
  • Start server: python -m mcp_server_snowflake.main
  • Development mode: uvicorn mcp_server_snowflake.main:app --reload

Test Commands

  • Run all tests: pytest
  • Run single test: pytest tests/test_file.py::test_function
  • Test coverage: pytest --cov=mcp_server_snowflake

Lint & Format

  • Lint: ruff check .
  • Format code: ruff format .
  • Type check: mypy mcp_server_snowflake/

Code Style Guidelines

  • Use Python 3.10+ type annotations everywhere
  • Format with Ruff, line length 88 characters
  • Organize imports with Ruff (stdlib, third-party, first-party)
  • Use async/await for Snowflake queries via snowflake-connector-python
  • Prefer dataclasses or Pydantic models for structured data
  • Follow PEP8 naming: snake_case for functions/variables, PascalCase for classes
  • Document public functions with docstrings (Google style preferred)
  • Handle database exceptions with proper logging and client-safe messages
  • Parameterize all SQL queries to prevent injection vulnerabilities
  • Use environment variables for configuration with pydantic-settings

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.
