PLwC Personal MCP Server

PLwC Personal 1.0.0

Controlled local access for AI assistants, persistent profiles and governed changes.

PLwC lets compatible AI assistants read and organise allowed local files, create and read documents, and run Python or Node.js in isolated Docker environments under locally configured rules. Persistent profiles retain preferences and working context across sessions and compatible clients. The Governor separates proposed lasting profile changes from their explicitly confirmed application.

PLwC provides the local gateway and tools; you choose the AI client and model. Requests and returned contents can still be processed by an external AI provider.

Downloads and documentation

• Official release: Windows setup, checksums, sources and browser packages
• Full software description in German: 65 pages, 22 diagrams
• Full software description in English: 62 pages, 22 diagrams
• Website and installation guidance

PLwC Personal and its gateway use version 1.0.0. The browser extension, PLwC Personal Chat Bridge, uses version 2.0.0 for Chrome and Edge; its store publication is separate. The bridge protocol is 1.0.0.

What is included

• A bilingual Windows installer with the gateway, configuration and selectable client integrations.
• Bounded workspace file and directory operations.
• DOCX, XLSX, PPTX, PDF and ZIP operations through the document worker.
• Separate Docker runtimes for documents, Python and Node.js. Sandbox execution has no network access and no automatic host-shell fallback.
• Local profiles, Compile, Reflection, memory and Governor Plan/Apply workflows.
• A local Chat Bridge for ChatGPT in supported browsers; native STDIO integration for compatible MCP clients.

The gateway exposes exactly eight tools: plwc_status, plwc_describe, plwc_profile, plwc_reflection, plwc_governor, plwc_sandbox_run, plwc_workspace_operation and plwc_document_operation.

Installation and integrity

Use Windows 11 x64. Python is required for the gateway; Node.js is additionally required for the Chat Bridge. Docker Desktop with Linux containers and WSL 2 is required for document and sandbox operations. The installer checks prerequisites and asks before optional runtime downloads.

Without available Docker runtimes, profile and workspace functions remain usable in Safe Mode; document and sandbox operations are unavailable.

The official installer is PLwC-Setup-1.0.0-installer-r27.exe, SHA-256:

aa1650fd560b73d0920ce6a4f070f290602cafe271b35e6b6314fa3af25ffe23

The EXE has no Windows Authenticode signature (NotSigned). Its release manifest has an independently verified RSA signature. The release includes the signed manifest, the public trust anchor, the final runtime lock and SHA256SUMS.txt.

The unchanged V9 runtime digests are:

Sources, licenses and support

The release sources are bound to commit 0c1c367c00bb7f5bb265d129f4daa7b73167b313 and tag v1.0.0. Changes to this README do not alter that release tag or its runtime/installer artifacts.

Corresponding GPL/LGPL sources, image mapping and replacement instructions are provided alongside the binaries. Third-party components retain their own licenses and applicable modification and replacement rights.

PLwC-owned components use the PolyForm Internal Use License 1.0.0, with Personal Use Permission and Official Redistribution Permission. These permit the specified private/internal use and free sharing of complete, unmodified official releases. Modified distribution and commercial offerings require a separate agreement. Earlier lawfully published Apache 2.0 content retains its original rights; see licensing.

Known status inconsistency: successful Python and Node.js executions can report sandbox_ready: false. The agreed execution tests completed successfully; this display inconsistency is documented.
