How do I make Cursor or GitHub Copilot auto-invoke the Context7 MCP without manual prompting?

Question

When using the Context7 MCP server with Cursor or GitHub Copilot, I have to manually prompt the model to call it, which is tedious. Is there a rules file or IDE setting I can add so the model automatically uses Context7 for framework, library, or API tasks, and what exact configuration should I use?

Status: explained — the issue was closed after a commenter shared a rules-file approach and the maintainer pointed to the official docs section at https://context7.com/docs/usage#auto-invoke-context7, inviting pull requests if the docs should be improved.

A commenter reported that this works fine for them with a local rules approach.

For Cursor, create a rule file named `context7.mdc`:

```
---
description: 
globs: 
alwaysApply: true
---
If a task involves a specific framework, library, or API — either explicitly or implicitly — use the context7 MCP tool to fetch the latest documentation instead of relying on training data.
```

For GitHub Copilot, add an instruction to `settings.json`:

```json
{
  ...
  "github.copilot.chat.codeGeneration.instructions": [
    {
      "text": "When asked to execute a task using a specific framework, library or API, or when that is heavily implied in the context, use the context7 MCP tool to retrieve current documentation rather than relying on training data."
    }
  ],
}
```

The commenter said this worked for them. The maintainer's referenced docs section is the place to check for the currently supported auto-invoke behavior.

**What @mruijzendaal tried on GitHub** (Worked)

Created a Cursor rule file `context7.mdc` with `alwaysApply: true` and a rule instructing the model to use the context7 MCP tool for framework/library/API tasks, and also added a matching instruction to GitHub Copilot's `settings.json`. The commenter reported this worked fine.
