• citations: Array of source URLs
• model: Model used
• usage: Token statistics

2. Complex Reasoning

For analytical queries requiring deep thinking:

mcp__scraper__perplexity_reason(
    query="Compare React Server Components vs traditional SSR approaches. Consider performance, developer experience, and migration complexity.",
    temperature=0.3,
    max_tokens=4000
)

Use cases:

• Technology comparisons

mcp__scraper__perplexity_reason(
    query="Should I use a monorepo or polyrepo structure for a microservices architecture? Consider team size of 15 developers, 8 services, and CI/CD complexity."
)

Code Pattern Research

mcp__scraper__perplexity(
    messages=[
        {"role": "user", "content": "What is the recommended way to handle form validation in React 19 with server actions?"}
    ]

)

Best Practices

Choose the Right Tool

• perplexity: Factual queries, lookups, simple questions
• perplexity_reason: Comparisons, trade-offs, complex analysis

Temperature Settings

# Factual accuracy (recommended for most queries)
temperature=0.3

# More creative/exploratory responses
temperature=0.7

# Maximum creativity (use sparingly)
temperature=1.0

Working with Citations

Responses include numbered citations [1], [2], etc. matching URLs in the citations array:

{
    "content": "Next.js 15 introduces several features [1] including improved caching [2]...",
    "citations": [
        "https://nextjs.org/blog/next-15",
        "https://nextjs.org/docs/caching"
    ]
}

Iterative Research

Build on previous answers:

# Initial query
mcp__scraper__perplexity(messages=[
    {"role": "user", "content": "What is Zustand?"}
])

# Follow-up with context
mcp__scraper__perplexity(messages=[
    {"role": "user", "content": "What is Zustand?"},
    {"role": "assistant", "content": "Zustand is a state management library..."},
    {"role": "user", "content": "How does it compare to Redux Toolkit for a medium-sized application?"}
])

Requirements

The Perplexity tools require PERPLEXITY_API_KEY environment variable to be set on the scraper MCP server. Without it, these tools will not be available.
