What is super-mcp-server CLAUDE.md?

Project instructions for a Go MCP server that lets Claude send plain-language data questions to the SuperSQL command-line tool. It can also find data files in directories.

Use it when developing or testing queries over supported data files, listing files, or maintaining the Go server that connects Claude with SuperSQL.

It explains the server's two tools, required external program, code conventions, and testing expectations before changes are made.

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 5.1	$0.01183	$0.01183
Opus 5.5	$0.00473	$0.00473
Sonnet 5.5	$0.00237	$0.00237

Security

Grade A, and why

super-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 2mo 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.

Super MCP Server Development Guide

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Model Context Protocol (MCP) server implementation in Go that provides SuperSQL querying capabilities. It acts as a bridge between Claude Desktop and the Super data processing tool, allowing natural language queries to be executed against various data formats.

Core Architecture

Single-file MCP server (main.go) implementing two primary tools:
- query: Executes SuperSQL queries via the external super command
- list_files: Discovers data files in directories
Tool registration pattern: Uses the MCP Go SDK's tool registration system
External dependency: Requires the super command-line tool to be installed and in PATH

Code Style Guidelines

Imports: Standard library first, third-party second, internal packages last
Error Handling: Use if err != nil with meaningful error returns/wrapping
Testing: Use testify for assertions, mock interfaces when needed
Naming:
- Variables/fields: camelCase
- Functions/methods: CamelCase
- Packages: single lowercase word
Commits and Pull Requests:
- Commits should be atomic and have a descriptive commit message
- Pull requests should be made against the main branch
- Don't mention claude in the commit message

Planning Phase

Use gh issue view to get the issue details
Understand the problem described in the issue
Ask clarifying questions if necessary
Understand the prior art for this issue
- Search the scratchpads for previous thoughts related to the issue
- Search PRs to see if you can find history on this issue
- Search the codebase for relevant files
Think harder about how to break the issue down into a series of small, manageable tasks
Document your plan in a new scratchpad
- Include the issue name in the filename
- Include a link to the issue in the scratchpad

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.
