What it does

Nemo is an agent skill from ChengHua926/nemo-skill. Search engine for MCP tools and agent skills. Search 790+ MCP server tools and 760+ agent skills in one place, call remote MCP tools, and get full skill instructions via simple HTTP API.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files (for example `README.md`).

It sits in Agent Workflows, covering MCP servers and REST APIs. It works with Model Context Protocol.

When your agent uses it

Tasks that involve REST APIs

Example prompts

“/nemo”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Search: curl ".../api/search?q=file+conversion"
If result is type: "skill" → get instructions: curl ".../api/skill/SKILL_NAME" → follow them
If result is type: "mcp_tool" → call it: POST .../api/call with endpoint, tool, args

What it can do on your machine

Read from SKILL.md and the folder at commit 438f85b. 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:
- curl
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:
- nemo.25chenghua.workers.dev
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

Nemo loads about 433 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 152 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~48
When it runs · the whole SKILL.md, loaded when a task matches: ~433

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 152 words (~433 tokens).

“Nemo indexes MCP tools and agent skills into a single searchable catalog. Use it to discover tools on demand via HTTP.”
