# setup-context7-mcp

Set up Context7 MCP server to provide real-time access to library and framework documentation, eliminating hallucinations from outdated training data.

* Purpose - Configure documentation access for your project's technology stack
* Output - Working Context7 integration with CLAUDE.md configuration

```bash
/mcp:setup-context7-mcp [technologies]
```

## What is Context7?

Context7 is an MCP server that fetches up-to-date documentation with code examples for any library or framework. Instead of relying on potentially outdated training data, the LLM can query actual documentation in real-time.

Benefits:

* Access latest API references and code examples
* Eliminate hallucinations about deprecated methods or incorrect signatures
* Get version-specific documentation for your exact dependencies
* Reduce back-and-forth when the LLM suggests outdated patterns

## Arguments

Optional list of languages and frameworks to configure documentation for. If omitted, the command analyzes your project structure to identify relevant technologies.

Examples:

* `react, typescript, prisma` - Specific technologies
* `nextjs 14, tailwind` - Version-specific documentation
* (no arguments) - Auto-detect from project files

## How It Works

1. **Availability Check**: Verifies if Context7 MCP server is already configured
2. **Setup Guidance**: If not available, guides you through the installation process for your operating system and development environment
3. **Technology Analysis**: Parses your input or scans project structure to identify relevant documentation
4. **Documentation Search**: Queries Context7 to find available documentation IDs for your technologies
5. **CLAUDE.md Update**: Adds recommended library IDs and usage instructions to your project configuration

## Usage Examples

```bash
# Configure for a React/TypeScript project
> /mcp:setup-context7-mcp react, typescript, @tanstack/react-query

# Let the command detect technologies from your project
> /mcp:setup-context7-mcp

# Specific framework versions
> /mcp:setup-context7-mcp nextjs 14, prisma 5, zod
```

After setup, your CLAUDE.md will include:

```markdown
### Use Context7 MCP for Loading Documentation

Context7 MCP is available to fetch up-to-date documentation with code examples.

**Recommended library IDs**:

- `react` - React core library documentation
- `typescript` - TypeScript language reference
- `prisma` - Prisma ORM documentation
```

## Best Practices

* Run early in project setup to establish documentation access from the start
* Include specific versions when working with rapidly evolving libraries
* Review the generated documentation IDs and remove any that are not relevant
* Re-run when adding new major dependencies to your project

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://cek.neolab.finance/plugins/mcp/setup-context7-mcp.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
