# MCP Servers Setup Status

Tracking the setup and validation of MCP/LSP servers via Docker Compose.

Last validated: 2026-01-22

## Validation Summary

**Working MCP Servers (tested with MCP initialize protocol):**
- ✓ ghost-mcp: Working (ghost-mcp-ts v1.0.0) - requires GHOST_API_URL, GHOST_ADMIN_API_KEY
- ✓ penpot-mcp: Working (Penpot MCP Server v1.25.0) - requires PENPOT_URL, PENPOT_TOKEN
- ✓ docker-mcp: Working (docker-mcp v0.1.0)
- ✓ audiobook-mcp: Working (audiobook-library v1.1.0) - requires AUDIOBOOK_ROOT
- ✓ bitwarden-mcp: Working (Bitwarden MCP Server v2026.1.0) - requires BITWARDEN_* env vars
- ✓ context7-mcp: Working (Context7 v2.1.0) - Takes >10s to initialize
- ✓ drawio-mcp: Working (drawio-mcp-server v1.4.0) - Takes >10s to initialize
- ✓ redmine-mcp: Working (Redmine MCP server v1.25.0) - Takes >10s to initialize

**MCP Servers with Configuration Issues:**
- ⚠ proxmox-mcp: Requires PROXMOX_MCP_CONFIG file path (not individual env vars) - incompatible with Crush's docker run approach
- ⚠ imap-mcp: Working but requires IMAP_HOST, IMAP_USERNAME, IMAP_PASSWORD env vars

**HTTP-based MCP Servers:**
- nextcloud-mcp: HTTP-based on port 8083, needs to be started via `docker compose up -d nextcloud-mcp`

**Pending Build:**
- discourse-mcp, cloudron-mcp, postizz-mcp, snipeit-mcp, docspace-mcp
- kubernetes-mcp-server, terraform-mcp-server, mcp-ansible
- wordpress-mcp, matomo-mcp-client, elasticsearch-mcp

**LSP Servers:**
- ✓ bash-language-server: Built (190MB) - configured in crush.json
- ✓ docker-language-server: Built (49.2MB) - configured in crush.json
- ✓ marksman: Built (144MB) - configured in crush.json

## Known Issues

1. **ProxmoxMCP**: Requires a JSON config file (PROXMOX_MCP_CONFIG) instead of individual environment variables. This doesn't work with Crush's `docker run` approach which can't easily mount config files.

2. **Slow initialization**: Some MCP servers (context7, drawio, redmine) take >10 seconds to initialize, likely due to downloading dependencies on first run.

3. **Validation script**: Fixed bash script to use `echo |` instead of `<<<` for proper Docker stdin handling.

4. **Docker config warning**: Non-critical warning about `/home/charles/.docker/config.json` being a directory (not a file). Doesn't affect MCP server operation.

## Usage

To build and start a specific server:
```bash
docker compose up -d <service-name>
```

To view logs:
```bash
docker compose logs -f <service-name>
```

To stop a server:
```bash
docker compose stop <service-name>
```

To rebuild a server after changes:
```bash
docker compose build --no-cache <service-name>
```

To test MCP server with Crush:
```bash
# 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-.
