Direct Usage

import asyncio
from pvlwebtools import web_search, web_fetch

async def main():
    # Search (requires SEARXNG_URL env var)
    results = await web_search("python async best practices", max_results=5)
    for r in results:
        print(f"{r.title}: {r.url}")

from pvlwebtools import SearXNGClient

client = SearXNGClient(url="http://localhost:8888")
if client.check_health():
    results = await client.search("query", domain_filter="wikipedia.org")

# Optional: enable verbose logging (sent to stderr)
export VERBOSE=1

# Run server
uvx pvl-webtools-mcp

Configuration

Environment Variable	Description
SEARXNG_URL	SearXNG instance URL (required for web_search)
LOG_LEVEL	Optional logging level for the MCP server (DEBUG, INFO, etc.). Logs are emitted on stderr so stdio transport stays valid.
VERBOSE	Convenience flag; set to 1/true to enable debug logging without specifying a level.

Legacy aliases PVL_MCP_LOG_LEVEL and PVL_MCP_VERBOSE are still accepted for backward compatibility.
