daytona-mcp-interpreter: Instructions file for Claude Code

CLAUDE.md

daytona-mcp-interpreter CLAUDE.md is an instructions file for Claude Code from nibzard/daytona-mcp-interpreter. It costs 447 tokens per session, scanned C, original, Apache-2.0.

Development instructions for a Python MCP interpreter built around Daytona, a service for running code in managed environments. They cover setup, commands, project structure, style, and configuration.

In plain words
What is it for?
Use them when developing the server, installing dependencies, inspecting it with MCP Inspector, viewing logs, building the package, or following its Python coding conventions.
Why use it?
They give contributors a shared way to run, inspect, test, build, and maintain the interpreter. This reduces uncertainty when changing the project.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is nibzard/daytona-mcp-interpreter's own configuration. It tells Claude Code how to work on daytona-mcp-interpreter 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 daytona-mcp-interpreter 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 C, and why

daytona-mcp-interpreter CLAUDE.md scanned grade C with 1 finding 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 11d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Daytona MCP Interpreter Development Guide

Build Commands

  • Run server: uv run src/daytona_mcp_interpreter/server.py
  • Test with MCP Inspector: npx @modelcontextprotocol/inspector uv --directory . run src/daytona_mcp_interpreter/server.py

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.
