microcms-mcp-server: Instructions file for Claude Code

CLAUDE.md

microcms-mcp-server CLAUDE.md is an instructions file for Claude Code from microcmsio/microcms-mcp-server. It costs 2,174 tokens per session, scanned A, original, MIT.

An MCP server for managing microCMS, a cloud content-management service, through AI assistants such as Claude. It supports content records and media files through eight listed API tools.

In plain words
What is it for?
Use it to list, read, create, update or delete content, and to list or upload media files in a microCMS service.
Why use it?
It removes the need to build separate instructions for connecting an assistant to microCMS and carrying out common content-management actions.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is microcmsio/microcms-mcp-server's own configuration. It tells Claude Code how to work on microcms-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything microcms-mcp-server configures →

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

microcms-mcp-server CLAUDE.md 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 2mo 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 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.
