mcp-web-search
Provides web search and site content access via DuckDuckGo, allowing AI agents to search the web and retrieve page content.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-web-searchsearch for latest AI news"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-web-search
A local MCP server that gives Claude or IBM Bob or other Agents web search and page-fetching capabilities. Built to work around:
the network restrictions that Claude organisation accounts operate under.
no built-in "web search" capabilities.
Why this exists
Claude.ai organisation accounts restrict outbound network access to a fixed domain allowlist. General web search and browsing are blocked and regular members cannot change that. Personal accounts have built-in web search and don't have this problem.
This server runs locally on your machine — where the internet is unrestricted — and proxies web requests back to Claude via the MCP protocol. If you've ever hit host_not_allowed with no way to fix it, this is for you.
IBM Bob does not have built-in web-browsing or internet capability due.

Key design decisions
No authentication on the server
Decision: The server accepts all requests without any auth token or API key.
Why: It only binds to 127.0.0.1 by default and is intended as a personal local tool — adding auth would be friction with no real security benefit in that context.
Do not change because: adding auth here would also require changes to every Claude Desktop config that uses this server.
Raw urllib instead of httpx / requests
Decision: access_site uses the stdlib urllib.request only.
Why: Avoids an extra dependency for a single HTTP call. ddgs already handles the search transport.
Do not change because: it keeps the dependency surface minimal; only revisit if redirect handling or TLS behaviour becomes a problem.
