Retrieve real-time stock quotes using Octagon MCP. An agent skill from OctagonAI/skills.

  • Works in 4 steps: Identify the Stock → Execute Query via Octagon MCP → Expected Output → …

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Stock Quote is an agent skill from OctagonAI/skills. Retrieve real-time stock quotes using Octagon MCP. Use when you need current price, day range, 52-week range, volume, market cap, and moving averages for any publicly traded stock.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `README.md`, `marketplace.json` and `references/interpreting-results.md`).

It sits in Business, Finance & HR, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: A collection of Claude skills for agentic financial research by Octagon. The licence is MIT.

When your agent uses it

  • You need current price
  • Moving averages for any publicly traded stock

Example prompts

  • “/stock-quote”

Workflow steps

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

  1. Identify the Stock
  2. Execute Query via Octagon MCP
  3. Expected Output
  4. Interpret Results

What it can do on your machine

Read from SKILL.md and the folder at commit 51e938c. 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 (its code samples are json).

    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

Stock Quote loads about 1.4k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 512 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
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.6k

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.

Analysis Tips

  1. Compare to averages: Price vs. 50-day and 200-day MA shows trend.

  2. Check volume: High volume confirms price moves.

  3. Range position: Near highs = strength, near lows = weakness.

  4. Market cap context: Larger caps typically less volatile.

  5. Time of day: Opening and closing often most volatile.

  6. Pre/post market: Less liquidity, wider spreads.
