fix: complete MCP server validation and documentation

- Fixed penpot-mcp Dockerfile for monorepo build (added data/ copy)
- Fixed snipeit-mcp Dockerfile COPY path and entrypoint
- Completed validation of all pending MCP servers
- Updated STATUS.md with comprehensive validation results
- Added JOURNAL.md entry documenting session work

Validation summary:
- terraform-mcp: Working (MCP handshake validates)
- 6 servers require config/env vars (matomo, nextcloud, paperless, postizz, redmine)
- 6 servers have build/runtime issues (discourse, revas, snipeit, proxmox, penpot, mcp-ansible)

+### MCP Server Validation Complete
+
+**Date/Time**: 2026-02-19 16:30:00 EST
+**Work**: Completed validation of all remaining MCP servers
+
+**What was done**:
+
+1. **Fixed Dockerfile issues**:
+   - penpot-mcp: Fixed monorepo build - added COPY for data/ directory containing api_types.yml
+   - snipeit-mcp: Fixed COPY path (context is ./vendor, not ./vendor/snipeit-mcp)
+
+2. **Validated all pending MCP servers**:
+   - terraform-mcp: **Working** - responds to MCP handshake without config
+   - nextcloud-mcp: Config required - needs NEXTCLOUD_HOST env var
+   - matomo-mcp: Config required - needs MATOMO_HOST, MATOMO_TOKEN_AUTH, OPENMOST_MCP_TOKEN
+   - paperless-mcp: Config required - needs baseUrl and token args
+   - postizz-mcp: Config required - needs POSTIZ_API_KEY env var
+   - mcp-redmine: Config required - needs REDMINE_URL env var
+
+3. **Identified upstream issues**:
+   - discourse-mcp: Build failed - TypeScript TS2345 error in upstream
+   - reverse-engineering-assistant: Build failed - Ghidra download 404
+   - snipeit-mcp: Runtime ImportError - depends on private snipeit-api package with different API
+   - proxmox-mcp: Runtime error - FastMCP module path changed
+   - penpot-mcp: Transport mismatch - uses HTTP/WebSocket, not stdio
+   - mcp-ansible: Runtime error - package not in PyPI registry
+
+4. **Updated STATUS.md** with comprehensive validation results
+
+**Validation Pattern Used**:
+```bash
+echo '{"jsonrpc":"2.0","method":"initialize","id":1,"params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' | timeout 10 docker run --rm -i kneldevstack-aimiddleware-{service}
+```
+
+**Final MCP Server Count**:
+- Working without config: 14 (audiobook, bitwarden, blender, cloudron, context7, docker, docspace, drawio, freecad, ghost, gimp, kubernetes, terraform, ghidra)
+- Config required: 8 (matomo, nextcloud, paperless, postizz, redmine, imap, webserial, kicad)
+- Build/Runtime issues: 6 (discourse, reverse-engineering-assistant, snipeit, proxmox, penpot, mcp-ansible)
+- Blocked: 1 (wordpress - PHP plugin)
+
+**Files Modified**:
+- dockerfiles/penpot-mcp/Dockerfile
+- dockerfiles/snipeit-mcp/Dockerfile
+- STATUS.md

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.
