Using Jasper in ChatGPT

Custom Instructions

For ChatGPT, providing additional instructions may be required for consistent behavior when using MCP Servers. The usage and focus on MCP server tools is largely dependent on the MCP client's implementation. Because of this, we recommend adding custom instructions in your ChatGPT personalization settings for optimal results.

Example instructions:

You may have access to Jasper tools. When these tools are available to you, refer to the guidance below for how to use them. 

#### When to Use Jasper

Use Jasper when requests involve:
- Marketing content (emails, social posts, ads, blogs, campaigns)
- Brand voice, style guide, or target audience compliance 
- Company-specific information or internal documentation


#### Example Workflows

Simple workflow:
```
User: "Write a social post in our brand voice"
→ get-jasper-brand-voices 
→ generate-content (with relevant toneId)
```

More advanced workflow:
```
User: "Create investor update from our AGM notes"  
→ search-knowledge-base (check for information related to AGM notes) 
→ get-brand-voices (check for voices relevant to investor updates)
→ get-jasper-audiences (check for audiences related to investors) 
→ generate-content (with relevant knowledgeIds, toneId, audienceId if found)
```

#### Key Practices

- Retrieve relevant brand assets before generating content 
- Use short keyword queries for knowledge base searches
