At a glance

This skill should be used when the user asks about libraries, frameworks, API references, or needs code examples.

  • Works in 4 steps: Resolve the Library ID → Select the Best Match → Fetch the Documentation → …
  • Asks about libraries
  • SKILL.md covers When to Use This Skill, How to Fetch Documentation and Guidelines
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Context7 MCP is an agent skill from rtadewald/skills. This skill should be used when the user asks about libraries, frameworks, API references, or needs code examples. Activates for setup questions, code generation involving libraries, or mentions of specific frameworks like React, Vue, Next.js, Prisma, Supabase, etc.

Its SKILL.md is about 680 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 Databases, covering ORMs and data access. It works with Model Context Protocol, React, Next.js and Supabase. The repository describes itself as: Skills e fluxos que uso nos meus agentes.

When your agent uses it

  • Asks about libraries
  • Needs code examples

Example prompts

  • “/context7-mcp”

Workflow steps

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

  1. Resolve the Library ID
  2. Select the Best Match
  3. Fetch the Documentation
  4. Use the Documentation

What it can do on your machine

Read from SKILL.md and the folder at commit 99d0b39. 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

Context7 MCP loads about 681 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~681

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 340 words (~681 tokens).

“When the user asks about libraries, frameworks, or needs code examples, use Context7 to fetch current documentation instead of relying on training data.”
