Managing MCP Index

What it does

When your agent uses it

• Asked to: sync MCP index
• Enhance MCP descriptions
• AI template descriptions for MCP
• Recommend override

Example prompts

• “Use the managing-mcp-index skill to build and maintains templates/index.mcp.json for Comfy Cloud MCP tools”
• “/managing-mcp-index”

Requirements

• Python 3
• A credential in AI_API_KEY

Workflow steps

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

1. 1npm run mcp — refresh structured fields and merge cache.
2. 2npm run mcp:ai / npm run mcp:models — if AI copy needed.
3. 3Commit index.mcp.json and relevant scripts/data/mcp/*.json files.
4. 4Bump pyproject.toml version if template assets changed (repo convention).

What it can do on your machine

Read from SKILL.md and the folder at commit 8be1f8c. 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
  • python3

  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 these keys or tokens, usually read from environment variables:

  • AI_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Managing MCP Index loads about 1.9k tokens when it runs. Until then it costs about 187 tokens; SKILL.md has 589 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~187

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

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

• NoteMentions a .env fileSKILL.md:31

  tes for AI steps: copy `.env.example` → `.env`, set `AI_API_KEY`, `AI_BASE_URL`, `AI_MODEL`. Optional: `COMFYUI_REPO_PAT

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

Builds and maintains templates/index.mcp.json for Comfy Cloud MCP tools. Covers deterministic sync from index.json, AI-generated English descriptions, model registry profiles, template cache, recommend/freshness overrides, and API node scanning. Use when asked to: sync MCP index, index.mcp.json, mcp sync, enhance MCP descriptions, AI template descriptions for MCP, models_registry, template_cache, recommend override, freshness, MCP pipeline, run mcp, mcp:ai, update MCP metadata, regenerate MCP copy, Use Cases MCP descriptions. NOT for site SEO (site/generate-ai) or hub i18n (sync:i18n / managing-translations). Triggers on: mcp index, index.mcp, mcp sync, template cache, models registry, mcp ai, recommend, MCP description.

npm run mcp          # Step 1: sync index.json → index.mcp.json
npm run mcp:check    # Dry-run sync (no write)
npm run mcp:ai       # Step 2b: AI English descriptions (stale templates only)
npm run mcp:models   # Step 2a: AI model profiles in models_registry.json
npm run mcp:enhance  # Step 2a + Step 2b in the required order
npm run i18n         # Hub translations (NOT MCP — separate system)
