What it does

Archestra MCP Catalog Entry is an agent skill from archestra-ai/archestra. Use when adding a new MCP server to the public MCP catalog (mcp-catalog/data) or preparing/reviewing a catalog-entry PR. Derives the entry name from the server URL, live-probes remote servers to fill in tools/transport/auth, fetches and encodes the icon, and validates the manifest against the catalog schema before opening the PR.

Its SKILL.md is about 1.5k 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. It works with Model Context Protocol. The repository describes itself as: Enterprise AI Platform with guardrails, MCP registry, gateway & orchestrator.

When your agent uses it

  • Adding a new MCP server to the public MCP catalog (mcp-catalog/data)
  • Preparing/reviewing a catalog-entry PR

Example prompts

  • “/archestra-mcp-catalog-entry”

Requirements

  • Python 3
  • Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Derive the entry name from the URL (do not guess)
  2. Live-probe remote servers (machine-fill, don't transcribe docs)
  3. Write the manifest
  4. Validate before the PR
  5. Open the PR

What it can do on your machine

Read from SKILL.md and the folder at commit df802e7. 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
    • python3
    • npx
    • pnpm

    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:

    • github.com
    • mcp.linear.app
    • agenttools.wolfram.com
    • api.iconify.design
    • vendor.com

    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

Archestra MCP Catalog Entry loads about 1.5k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 440 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 440 words (~1,519 tokens).

“The catalog is two files under mcp-catalog/data/ (see mcp-catalog/README.md):”
