What it does

Revyl MCP is an agent skill from RevylAI/revyl-cli. Base MCP skill for Revyl tool-call orchestration. Use when users want direct MCP execution instead of shell commands.

Its SKILL.md is about 250 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

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

When your agent uses it

  • Users want direct MCP execution instead of shell commands
  • Tasks that involve MCP servers

Example prompts

  • “/revyl-mcp”

Workflow steps

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

  1. Use MCP tools only.
  2. Re-anchor frequently with screenshot() before stateful actions.
  3. Prefer one action per loop iteration unless the sequence is trivial and deterministic.
  4. If the user asks for shell-command guidance, switch to the revyl-cli skill family.
  5. When more than one device session may be live, including parallel agents sharing one MCP server, pass the session_id returned by…

What it can do on your machine

Read from SKILL.md and the folder at commit 496d6f4. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Revyl MCP loads about 247 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 117 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~247

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 117 words (~247 tokens).

“Use this skill when execution should happen through Revyl MCP tools.”
