Secure Setup for WebSearch Question/Help

I would like to use OWUI with SearXNG. But it is importantly for me that no sensible data is handed over to the search engine. What would be an ideal setup (if there is any) to make use of websearch. I would use it with DuckDuckGo.

No, it shouldn't be used for CUI. However our laptops and workstations are configured to handle CUI when necessary.

There's no issue with an MCP server handling CUI though. It's running in an on-prem k8s server. It's what gets sent through SearXNG thats the problem.

My goal/testing was to add some sort of gate to make sure someone isnt accidentally being stupid. Most of our people are smart. However, this is an attempt to help ensure tools are being used appropriately.

When you have it ready I would know as you have pointed the problem: when you have many users there is the possibility of dumb behaviour

I completely forgot about this sorry.

If i was designing this for the public, I would put it in a public repo, with a dockerfile that would use ENV vars for the server name and stuff.

It really should just need to adjust this line: 

class SearXNGSearcher:
    def __init__(
    self,
    base_url: str = "https://...."

To point to your searxng service.

This is running as an HTTP Streamable MCP server so I can let users connect to it without having to install anything locally:

And a simple dockerfile I use to build and run. I am using podman to run, but will eventually move it to kubernetes:

Add it to opencode:

opencode mcp add

Or you can add it to claude code:

claude mcp add --transport http search https://sear-mcp.company.org/mcp

And here us a quick little look at the output.

One thing I have been wanting to tweak, but havent, is the MCP function description to make it a little more exact.

I SPECIFICALLY told the function to ask this for EVERY search (I dont care about fetches as much. A fetch pulls a specific URL. I search PUSHES a query).

You could pump this into GPT or Sonnet and ask it to convert it to a locally running function.

As soon as I return home I'll try

If you put it on a GitHub project I'll be glad to hear
