What it does
Mobius MCP Stdio Invocation is an agent skill from mobius-system/mobius. Invoke any MCP (Model Context Protocol) server directly from the CLI via stdio JSON-RPC, with no Claude Code / harness dependency. Use when you need to call MCP tools (web search, image understanding, file ops, custom tools) from a shell script, CI job, or a session that doesn't have the MCP auto-loaded. Covers: installing uv/uvx (or npx), spawning the server, the JSON-RPC 2.0 handshake, tools/list discovery, tools/call invocation, and result parsing — with the MiniMax minimax-coding-plan-mcp package as a…
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `mcp_invoke.py`).
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, MiniMax and Bash. The repository describes itself as: Self-Evolving Multi-Agent Operation System.
When your agent uses it
- You need to call MCP tools (web search
- Image understanding
- Custom tools) from a shell script
- A session that doesnt have the MCP auto-loaded
Example prompts
- “/mobius-mcp-stdio-invocation”
Requirements
- Python 3
- Node.js
- A credential in MINIMAX_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 5fe32b1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
uvxclaudecurlshnpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.minimaxi.comastral.sh
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
MINIMAX_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mobius MCP Stdio Invocation loads about 2.9k tokens when it runs. Until then it costs about 144 tokens; SKILL.md has 968 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePipes a well-known installer script into a shellSKILL.md:62
| PyPI (`uvx`) | `curl -LsSf https://astral.sh/uv/install.sh \| sh` (one-time) | `uvx --from <pkg> <entrypoint> -y` |
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 968 words (~2,915 tokens).
“MCP servers speak JSON-RPC 2.0 over stdio — the server's stdin is the request stream, stdout is the response stream, stderr is for human logs. Any process that can spawn a subprocess and read/write its stdio can be an MCP…”
