Improve retrieve_tools diagnostics for annotation filters and automation-critical tools
Summary
I am using MCPProxy as a local lightweight gateway for many MCP servers, with retrieve_tools as the main way to keep tool schemas out of the agent context until needed. This works very well overall, but I ran into a failure mode where a tool existed and was callable, yet was effectively hidden from routine automation because annotation-based filtering removed it without a very actionable explanation.
I would like to propose a small set of discovery/diagnostic improvements rather

OAuth regression for runlayer backed servers
I was helping someone set mcpproxy up, and they ran into these errors to oauth:
{
"detail": [
{
"type": "missing",
"loc": [
"query",
"resource"
],
"msg": "Field required",
"input": null
}
]
}
This is a regression of https://github.com/smart-mcp-proxy/mcpproxy-go/issues/155
I had been running off the version on https://github.com/smart-mcp-proxy/mcpproxy-go/pull/255 and was able to reproduce once i merged main.

[Bug] MCP server connection issues
Some MCP servers aren't very stable. It might be their implementation issues or different protocol versions/approach to development.
One of the most annoying but also a very desirable is Jetbrains MCP. If i add SSE endpoint its just doesn't loads any tools. If i try stdio - it loads, but might lose the connection. Such connection issues can lead to dashboard freeze, which is a not a big deal most of the time. Application might even hang and only forced kill helps.
Im using xubuntu 25.04, runni

Listen port config setting being ignored

Avoid storing credentials in mcpproxy.json in plaintext
Right now, if you need things like API keys, hostnames, or anything else sensitive, you have to store it in plaintext in the config files. This means you can't easily store mcp_proxy.json in version control.
I'd love to be able to use something like macOS Keychain, 1password, etc. I could imagine having templating in command, env, etc, and expose things that way. I've used keyring-rs bindings for node before. I can't tell if this is golang bindings for it, or just using the same keyring name:

Not all mcp servers are relevant for all clients
There are tons of MCP out there that assume they are being run from the directory the MCP client is.
For example, ast-grep-mcp will run in the directory it’s started from, or take an explicit directory to run from.
If a user is running a single mcpproxy (which is encouraged by having things like a menu bar to manage), it could get confusing to add ast-grep-mcp to use in one project, but then another project ends up trying to call it and gets results

Docker images are needed
Hello there! :) First things first, thanks for your effort on this
One of the best HomeAssistant MCPs just support stdio transport at this moment, so your proxy is fixing it being in front.
I have a K8s cluster where I have deployed both. You can see the values for that here
Kubernetes 1.33+ support a mechanism to mount a Docker image as a volume in a pod, making this kind of "fixes" much more
