dev.io

dev.io is a command for Claude Code from amirtaherkhani/dev-io-mcp. It costs 16 tokens per session (230 once invoked), scanned A, original, MIT.

A command workflow for using the dev-io MCP server to publish, list, read, inspect, or record metrics for posts. A post is a written article, and metrics are measurements such as views or reactions.

In plain words
What is it for?
For publishing conversation or document summaries, listing and reading posts, viewing post information, and recording views, likes, or comments while protecting secrets and private data.
Why use it?
It gives common post operations one consistent entry point and prevents confusing a locally created file with a successfully published DEV.to article.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dev.io scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use the dev-io MCP server and the dev-io skill for this request.

Route the command from $ARGUMENTS:

  • publish or post: summarize the current conversation or supplied document, redact secrets, and call publish_post.
  • list: call list_posts and present the file names.
  • read or show: call read_post for the requested file.
  • info or stats: call get_post_info for the requested file.
  • view, like, or comment: call record_post_event with the matching event.

For publishing, return the local file path and clearly separate local creation from a DEV.to result. Never claim remote publication unless the MCP response contains remote.published: true and an article ID or URL. Never expose API keys or private conversation data.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
