Known Issues

Empty ahujasid Repositories (2026-02-17)

Investigation revealed that most ahujasid vendor repositories are empty (contain only .git folder, no code):

• kubernetes-mcp-server, ProxmoxMCP, terraform-mcp-server, nextcloud-mcp-server, snipeit-mcp, mcp-redmine, mcp-ansible, penpot-mcp, postizz-MCP
• discourse-mcp (previously documented) - also empty
• matomo-mcp-client - repo doesn't exist (404)

These repos cannot be used to build MCP containers. Alternative sources or official repos should be identified.

Alternative Repositories Available

• kubernetes-mcp: Use silenceper/mcp-k8s instead (has content and Dockerfile)

WordPress MCP Configuration (2026-02-17)

The WordPress MCP Adapter (@wordpress/mcp-adapter) is NOT a standalone MCP server:

• It is a PHP plugin that must be installed within a running WordPress instance
• Requires the WordPress Abilities API plugin (wordpress/abilities-api)
• Uses WP-CLI for STDIO transport: wp mcp-adapter serve --user=admin --server=mcp-adapter-default-server
• HTTP transport available via /wp-json/mcp/mcp-adapter-default-server
• The docker-compose.yml entry for wordpress-mcp needs to be reconfigured or removed
• For containerized use, would need a full WordPress + plugins image, not just the MCP adapter

Previously Documented Issues

• matomo-mcp: Vendor repository does not exist. The CloneVendorRepos.sh references https://github.com/ahujasid/matomo-mcp-client.git which returns 404. Unable to build until a valid source is identified.
• discourse-mcp: Vendor repository exists but is empty. The CloneVendorRepos.sh references https://github.com/ahujasid/discourse-mcp.git which has no commits. Unable to build until repository has content.

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>

To test MCP server with Crush:

# Stdio-based servers are run on-demand by Crush
# Configuration is in crush.json
# Crush automatically handles docker run -i --rm

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