Automated summary

Retrieves official library documentation and API references using Context7 MCP.

Strengths

  • Direct access to official docs without leaving the IDE.
  • Automatic library ID resolution for accurate results.
  • Supports multiple modes (code info) for different needs.

Limitations

  • Requires an active MCP configuration with Context7.
  • May not find obscure or deprecated libraries.
  • Relies on Context7 data availability.
When to use it

Use this skill when you need API signatures, usage examples, or official documentation for a specific library or package.

When not to use it

Do not use it for general programming questions unrelated to a specific library, or for concepts you are already familiar with.

Security analysis

Safe
Quality score85/100

The skill only instructs an AI to use a documentation-fetching MCP tool; it does not execute system commands, access sensitive data, or perform any destructive actions. No risks identified.

name: context7-mcp description: Retrieve official library documentation and API references. Use when the user asks for "docs", "API signature", "usage examples", or "how to use" a specific package.

Use Context7 MCP for library APIs

Instructions

  1. When asked about a library/package API, first resolve it: call resolve-library-id with the package name.
  2. If a valid ID is returned, fetch docs with get-library-docs (mode code for API/reference; info for conceptual) and a topic if relevant (e.g., hooks, routing).
  3. Cite snippets from retrieved docs; avoid guessing. Prefer latest page unless user specifies version.
  4. If multiple matches, pick the closest and mention ambiguity briefly before proceeding.
  5. If no match, ask for clarification or alternate names instead of inventing APIs.
  6. Do not rely on memory for API shapes when Context7 docs are available; re-fetch as needed for accuracy.

Example prompts

  • "查下某个 npm 包的 hook 签名，用 context7 搜"
  • "给我 next.js app router 的官方用法，先用 context7 mcp"
  • "mongodb driver 的插入示例，走 context7 的文档"

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/context7-mcp-for-library-apis-mm78nnzp/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/context7-mcp-for-library-apis-mm78nnzp' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/context7-mcp-for-library-apis-mm78nnzp/download' --output '.skill-downloads/context7-mcp-for-library-apis-mm78nnzp/SKILL.md.part' && mv '.skill-downloads/context7-mcp-for-library-apis-mm78nnzp/SKILL.md.part' '.skill-downloads/context7-mcp-for-library-apis-mm78nnzp/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/context7-mcp-for-library-apis-mm78nnzp'

openskills read 'context7-mcp-for-library-apis-mm78nnzp'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/context7-mcp-for-library-apis-mm78nnzp/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
