Feature request: optional bearer auth for the native Streamable HTTP /mcp endpoint
Summary
When running in PROXMOX_MCP_MODE=mcp-http, the native Streamable HTTP endpoint on
:8000/mcp accepts any request. PROXMOX_API_KEY does not apply to it — that key
only guards the OpenAPI proxy on :8811, and the two modes are mutually exclusive
processes, so there is currently no configuration in which /mcp is authenticated.
Since that endpoint exposes the full tool surface (power management, backups, guest creation/deletion within the token's ACL scope), the only availab

Feature Request: Whitelist of exposed tools to reduce token spend on local LLM
TL:DR: you should add a whitelist.json or environment (or both) to ONLY expose the MCP tools I care about so they are not surfaced to MCP clients, thus reducing the precious tokens the dormant tools take up just by existing.
Last night I had an infuriating and token-wasting session only to find out this isn't even a thing; but it should be 🥲
In an effort to reduce tokens on my LOCAL LLMs, I learned that JUST the fact of having MCP tools (enabled), not even USING them, but simply that they exi

Add option to configure DNS rebinding protection for MCP transport
Problem
When deploying ProxmoxMCP-Plus behind a reverse proxy or MCP gateway (e.g. agentgateway), the Python MCP SDK's DNS rebinding protection rejects requests with 421 Misdirected Request because the incoming Host header doesn't match localhost.
There's currently no way to configure this without patching the SDK at runtime.
Root Cause
In src/proxmox_mcp/server.py, the FastMCP() constructor is called without a transport_security parameter:
self.mcp = FastMCP(

### Compatibility: Home Assistant MCP client fails on nested payload schema ($ref/$defs) for get_containersArguments
## Summary
ProxmoxMCP-Plus appears to work with permissive MCP clients, but Home Assistant's MCP integration currently fails to load this server because at least one tool schema uses a nested `payload` object via `$ref`/`$defs`.
This causes HA to put the MCP config entry into `setup_retry`.
## Observed error in Home Assistant
Error converting schema Invalid schema, missing type: {'$defs': {'GetContainersPayload': {'properties': {'node': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'de

Missing container command execution setup
On previous version I managed to get this to work with your guide. I see now there's been a lot of changes and also this guide is no longer available. Can you help update it?
Great MCP btw!

Network binding settings in config.json are being ignored (hardcoded to 127.0.0.1, port 8000)
Hey,
I’ve been trying to get this running in a Docker container/LXC environment so I can point an external agent to it, but I’ve run into an issue where the server ignores the host and port settings defined in the mcp section of the config.json file.
The Issue: Even if I set mcp.host to 0.0.0.0 and change the port in the config file, the server still binds to 127.0.0.1:8000. This makes the Docker image essentially unreachable from the host or the rest of the network.
**Steps to Reproduce:

Why does /health return {"detail":"Not Found"} when running ProxmoxMCP-Plus in Docker?
I've been trying to deploy the ProxmoxMCP-Plus project. I've followed the instructions to set up the API Token (with PVE administrator permissions) and used Docker Compose to spin up the environment.
From the Dockerfile, the service seems to be running fine on port 8811, but I'm hitting a strange issue: whenever I try to access http://

STDIO transport aborts with SIGABRT on every shutdown (_enter_buffered_busy at interpreter finalization)
Under the STDIO transport the server aborts with SIGABRT on every shutdown instead of exiting cleanly. On macOS this surfaces as a "Python quit unexpectedly" crash dialog each time the MCP client disconnects; on Linux it produces a core dump / exit code 134.
Fatal Python error: _enter_buffered_busy: could not acquire lock for

Add HTTP Streamable MCP support
Currently when running in docker, it's not possible for an MCP client to connect due to the server only support STDIO. This prevent client on other host using the MCP server.
Would be great if we can support HTTP mode.
