Error: URL was not provided by the user. For security, you can only fetch URLs that were explicitly shared by the user in their messages.
Come on guys... first it's a read-only PostgreSQL MCP Server (no read or admin??)
Now you're taking away Claude Code's ability to do research and pull up documentation using fetch? that's insane?
It was amazing having Claude use Brave MCP to search and Fetch MCP to fetch documentation in real-time. I don't need to be in the middle slowing things down. I get this is a security thing, but can you make it togglable or make separate MCP servers where we can accept the risk? I'm developing in a vm with version control and secure env variables. I should be treated like an adult and permitted to accept these risks myself.
*edit: two things.
1) seems to be working now? which is odd because the error in the title was a system error, not something Claude was just making up (red text).
2) I LOVE CLAUDE CODE. It has been an amazing coding agent and partner. While of course it makes mistakes (we all do) the capabilities are phenomenal. The tool is amazing and I am deeply grateful to the team at Anthropic who must be working like crazy to build and maintain this solution.
-I felt my initial comment was a little brash, so I did want to recognize the considerable effort that goes into this product and express my gratitude. thanks all

I agree. This change took the tooling from incredible to irrelevant very quickly. I can’t whitelist domains or asking for information on certain libraries it now figures out the URL and then just refuses.
Yes, this was NOT thought threw, I understand the thinking but if you add a restriction you have to also add the ability for us to whitelist
This is a blocker indeed.
Claude should now be preferring your MCP fetch tool if one is available. Please let me know if you're seeing otherwise.
OK, so we need to set up an MPC to do this which one would be an example of
that to get around the continued warning that as Claude is doing research
on a topic to help solve a problem that the user didn’t explicitly give it
the URL it found on its own to go research. Happy to configure it just need
to know what to do and we might wanna make that more clear to the end user
as how to do it correctly.
