www-search-mcp 1.0.2

MCP server providing web search (DuckDuckGo), HTTP fetch, browser fetch (Playwright), and file download.

www-search-mcp

MCP (Model Context Protocol) server providing web search, HTTP fetch, browser-based fetch (Playwright), file download, and package search (PyPI, GitHub).

Gives AI assistants (Qoder, Claude Desktop, Cursor, etc.) the ability to search the web, read web pages, download files, and discover Python packages — all through a single MCP server with 7 tools.

System Requirements

Requirement	Version
uv	Install guide
Python	3.10+ (managed automatically by uv)
Playwright	Chromium browser (installed via post-install script)

Install uv

macOS / Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows (PowerShell):

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

macOS (Homebrew):

brew install uv

Installation

Option 1: Run directly with uvx (recommended)

No clone needed. Runs from PyPI. Updates automatically on each run:

uvx www-search-mcp

MCP client config:

{
  "mcpServers": {
    "www-search-mcp": {
      "command": "uvx",
      "args": ["www-search-mcp"]
    }
  }
}

Option 2: Install as a uv tool

# From PyPI
uv tool install www-search-mcp

# After installation, the command is available globally:
www-search-mcp

To update or reinstall:

uv tool upgrade www-search-mcp
# or force reinstall latest:
uv tool install --force www-search-mcp@latest

MCP client config (global tool):

{
  "mcpServers": {
    "www-search-mcp": {
      "command": "www-search-mcp"
    }
  }
}

Option 3: Run from local source (for development)

git clone https://github.com/naifs/www-search-mcp.git
cd www-search-mcp
uv sync
uv run www-search-mcp

To update:

git pull && uv sync

MCP client config (local source):

{
  "mcpServers": {
    "www-search-mcp": {
      "command": "uv",
      "args": [
        "run",
        "--project",
        "/absolute/path/to/www-search-mcp",
        "www-search-mcp"
      ]
    }
  }
}

Option 4: Install from built wheel

cd /path/to/www-search-mcp
uv build
uv tool install dist/*.whl

To update:

uv build && uv tool install --force dist/*.whl

Note: Playwright Chromium is installed automatically on first use when a browser tool is called. If auto-install fails (e.g. no network), run manually:

uv run python -m playwright install chromium

Quick Verification

# Search the web
uv run python -c "from www_search_mcp.server import web_search; r=web_search('python mcp protocol', max_results=3); print(r['status'], r['result_count'])"

# Fetch a page
uv run python -c "import asyncio; from www_search_mcp.server import web_fetch; r=asyncio.run(web_fetch('https://example.com')); print(r['status'], r['http_status'])"

# Search GitHub
uv run python -c "from www_search_mcp.server import web_search_github; r=web_search_github('fastapi', max_results=3); print(r['status'], r['result_count'])"

# Search PyPI
uv run python -c "from www_search_mcp.server import web_search_pypi; r=web_search_pypi('httpx', max_results=3); print(r['status'], r['result_count'])"

Troubleshooting

uv not found

Install uv and reopen your terminal. See System Requirements.

Dependencies missing

uv sync

Playwright browser not found

uv run python -m playwright install chromium

GitHub API rate limit exceeded

The GitHub API allows ~10 requests/minute without authentication. To increase the limit, set a GitHub token:

export WEB_GITHUB_TOKEN=ghp_your_token_here

Binary content error in web_fetch

web_fetch rejects binary content (images, PDFs, etc.). Use web_download instead to save binary files to disk.

MCP tools not appearing in client

1. Check that the MCP client config JSON is valid.
2. Ensure the --project path is absolute and correct.
3. Reload the MCP client after config changes.
4. Check WEB_DEBUG=true for detailed logs.

Wrong project path in config

The --project argument must point to the root directory of www-search-mcp (where pyproject.toml is located), not to the src/ subdirectory.
