DevSpace-MCP: Instructions file for Codex

AGENTS.md

DevSpace-MCP AGENTS.md is an instructions file for Codex, OpenCode from chenchihcu/DevSpace-MCP. It costs 351 tokens per session, scanned A, a copy of devspace-local-artifacts AGENTS.md, MIT.

Instructions for using DevSpace, a local development workspace exposed through MCP. It lets an MCP-compatible assistant read, search, edit, and run commands in approved project folders.

In plain words
What is it for?
Guiding an assistant through local coding tasks such as reading files, searching code, editing files, and running shell commands.
Why use it?
They explain how to work in the right folder and reuse its workspace connection instead of repeatedly opening the same project.

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

DevSpace-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 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.

Origin

What it actually says

DevSpace

This project exposes a local development workspace over MCP so ChatGPT, Claude, or another MCP-capable host can operate directly on this machine's approved development directories.

The goal is not to delegate work to a separate local coding agent. The MCP host should call tools that read files, edit files, search code, and run shell commands directly against approved local project roots.

Pi's SDK is currently used as the backend adapter for mature local coding primitives such as read, edit, write, grep, find, ls, and bash. DevSpace wraps those primitives behind a remote Streamable HTTP MCP interface, suitable for use through a Cloudflare Tunnel.

The model-facing workflow is workspace based. MCP clients should call open_workspace once per local project directory or worktree, then reuse the returned workspaceId for subsequent tool calls in that same folder. Do not call open_workspace again for the same folder unless the workspaceId is rejected as unknown, the client switches folders/worktrees or checkout/worktree mode, or the user explicitly asks to reopen. AGENTS.md files are returned automatically by open_workspace and by later tool calls when the requested path enters a directory with instructions that have not been loaded for that workspace.

Core constraints:

  • Treat this as remote access to the local machine; security is part of the core design, not a later add-on.
  • Start with a narrow filesystem allowlist.
  • Prefer explicit, inspectable tool calls over autonomous local agent loops.
  • Keep the first version small enough to validate with real ChatGPT/Claude MCP clients before adding UI or workflow features.
Changes

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.
