Known Issues

nextcloud-mcp

Server crashes on startup if OAuth endpoint is unreachable. Server tries to connect to Nextcloud during initialization to fetch OAuth discovery document. If connection fails, server raises ConnectError and exits before responding to JSON-RPC initialize.

imap-mcp

Server crashes on startup if IMAP connection fails. Server tries to connect to IMAP during lifespan context entry. If connection fails, server raises ConnectionError and exits before responding to JSON-RPC initialize.

webserial-mcp

Requires bridge server (esp32_bridge_server.py) running on host at ws://host.docker.internal:3000 plus browser with WebSerial access and ESP32 hardware.

kicad-mcp

Host-only - requires KiCAD installed on the host machine. The pcbnew Python module cannot be pip-installed and is only available with a full KiCAD installation.

wordpress-mcp

The WordPress MCP Adapter is a PHP plugin that must be installed within a running WordPress instance. It requires WordPress + Abilities API plugin + MCP Adapter plugin. Not suitable for containerized standalone deployment.

postizz-mcp

Uses HTTP transport (listens on port 3084) instead of stdio MCP. Not compatible with standard MCP clients that expect stdio communication.

discourse-mcp

Build failed with TypeScript TS2345 error in upstream repository. Cannot fix locally.

proxmox-mcp

Runtime ModuleNotFoundError: No module named 'mcp.server.fastmcp'. The FastMCP library changed its import paths - needs Dockerfile update to install correct mcp package version.

snipeit-mcp

Runtime ImportError: cannot import name 'SnipeIT' from 'snipeit'. The upstream snipeit-mcp depends on a private 'snipeit-api' package (referenced via local file path) that has a different API than the public PyPI 'snipeit' package. The public package exports Assets/Licenses/Components classes, not SnipeIT.

penpot-mcp

Uses HTTP/WebSocket transport instead of stdio MCP. Not compatible with standard MCP client connections. Multiple endpoints: HTTP at :4401/mcp, SSE at :4401/sse, WebSocket at :4402.

mcp-ansible

Package not found in PyPI registry. Upstream issue - the package may not be published.

reverse-engineering-assistant

Build failed - Ghidra download URL returns 404. The version number in the Dockerfile download URL is incorrect.

Usage

To build and start a specific server:

docker compose up -d <service-name>

To view logs:

docker compose logs -f <service-name>

To stop a server:

docker compose stop <service-name>

To rebuild a server after changes:

docker compose build --no-cache <service-name>

Note: Use lowercase service names from compose file. Container names will be prefixed with kneldevstack-aimiddleware-.
