What it does

MCP Integration is an agent skill from LunCoSim/lunco-sim. Install, register, test, or troubleshoot the LunCoSim MCP server and its portable skills. Use when an agent needs MCP tools, skill discovery, host configuration, an installed npm package, or API connection troubleshooting.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers and Skill management. It works with Model Context Protocol and npm. The repository describes itself as: Collaborative Multiphysics Cosimulator For Space Missions 🌎🚀🌚. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit d1c6f00. 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
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

MCP Integration loads about 547 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 254 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~60
When it runs · the whole SKILL.md, loaded when a task matches: ~547

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 passed

The automated check found no risky patterns in SKILL.md.

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.

description: Install, register, test, or troubleshoot the LunCoSim MCP server and its portable skills. Use when an agent needs MCP tools, skill discovery, host configuration, an installed npm package, or API connection troubleshooting.

MCP integration: connect the host to LunCoSim and its skills

Read mcp/README.md, skills/START-HERE.md, and docs/apps/README.md. The MCP server is a standard stdio server usable by Claude Code, Claude Desktop, Cline, Cursor, Windsurf, Codex, and other MCP-compatible hosts.

Lifecycle

Start this agent's production luncosim session with an explicit free --api PORT, from the same checkout and working directory as its terminal. MCP connects to that API; it does not launch, rebuild, or replace the simulator. Verify /api/ready and use DiscoverSchema for live commands.
Register either the published @lunco/mcp-server package or the checkout's .mcp.json. Other agents may run on their own ports; do not control their sessions or reuse an occupied API port.
Call list_skills or read lunco://skills before declaring that a workflow is unavailable. Use read_skill(name) or lunco://skills/<name> to load the portable Markdown runbook, then follow its owner and evidence rules.
Use simulation tools for the live API and skill resources for development guidance. They are complementary surfaces, not duplicate implementations.

For a source checkout, set LUNCOSIM_BIN to the freshly built production binary. For an installed GitHub build, set it to the installed command or absolute path. Node/npm packaging and Python catalogue validation are tooling choices; Python remains an optional LunCoSim integration, not a runtime dependency.

Acceptance

Test the package with npm pack --dry-run and confirm the tarball contains skills/*/SKILL.md. Test the server's skill listing and read operations without an API session; test simulation tools separately against a live /api/ready endpoint. Keep host-specific registration examples in mcp/README.md, not in individual skills.
