mcp-server-snowflake: Instructions file for Codex

AGENTS.md

mcp-server-snowflake AGENTS.md is an instructions file for Codex, OpenCode from christianclaudio/mcp-server-snowflake. It costs 826 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for an MCP server that exposes Snowflake, a cloud data platform, to AI clients. The server provides tools for databases, schemas, tables, SQL queries, and related operations.

In plain words
What is it for?
Developing or modifying Snowflake MCP tools, connection handling, SQL operations, and the server’s stdio or SSE interfaces.
Why use it?
They explain the project structure, supported connection methods, and development commands so agents can work on the server consistently.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is christianclaudio/mcp-server-snowflake's own configuration. It tells Codex and OpenCode how to work on mcp-server-snowflake itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server-snowflake configures →

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

mcp-server-snowflake 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 today.

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.

Project Overview

This is mcp-server-snowflake — an Enterprise Model Context Protocol (MCP) server exposing 140 tools for Snowflake's Data Cloud and Cortex AI. It runs over stdio or SSE and is consumed by AI clients (Claude Desktop, VS Code, Antigravity, Cursor, etc.).

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.
