Default Browser Headers: The server automatically includes realistic browser headers to prevent blocking:
- User-Agent: Chrome browser simulation
- Accept: Standard browser content types
- Accept-Language, Accept-Encoding: Browser defaults
- Security headers: Sec-Fetch-* headers for modern browsers
Custom headers in JSONRPC_MCP_HEADERS` will override defaults when there are conflicts.
fetch-json
Extract JSON content from a URL using JSONPath with extended features. Supports extensions like len, keys, filtering, arithmetic operations, and more. If 'pattern' is omitted or empty, the entire JSON document is returned. Supports different HTTP methods (default: GET).
fetch-text
Fetch text content from a URL using various HTTP methods. Defaults to converting HTML to Markdown format.
batch-fetch-json
Batch extract JSON content from multiple URLs with different extended JSONPath patterns. Supports all JSONPath extensions and optimizes by fetching each unique request only once. Executes requests concurrently for better performance. Supports different HTTP methods.
batch-fetch-text
Batch fetch raw text content from multiple URLs using various HTTP methods. Executes requests concurrently for better performance.

A Model Context Protocol (MCP) server that provides tools for fetching JSON data and web content from URLs. Features intelligent content extraction, multiple HTTP methods, and browser-like headers for reliable web scraping.
🎯 Why Use This?
Reduce LLM Token Usage & Hallucination - Instead of fetching entire JSON responses and wasting tokens, extract only the data you need.Traditional Fetch vs JSONPath Extract
❌ Traditional fetch (wasteful): ``json
// API returns 2000+ tokens
{
"data": [
{
"id": 1,
"name": "Alice",
"email": "[email protected]",
"avatar": "https://...",
"profile": {
"bio": "Long bio text...",
"settings": {...},
"preferences": {...},
"metadata": {...}
},
"posts": [...],
"followers": [...],
"created_at": "2023-01-01",
"updated_at": "2024-01-01"
},
// ... 50 more users
],
"pagination": {...},
"meta": {...}
}
`
✅ JSONPath extract (efficient):
`json
// Only 10 tokens - exactly what you need!
["Alice", "Bob", "Charlie"]
`
Using pattern: data[*].name saves 99% tokens and eliminates model hallucination from irrelevant data.
