PLwC Personal MCP server

PLwC — Personality Layer with Conscience

PLwC is a local, model-independent governance gateway for AI tool access, persistent context and controlled memory. It is not the agent and it is not the language model. It is the independent control layer between the AI host, the model and local tools.

PLwC exposes one visible MCP server, routes all capabilities through policy and governance checks, and provides workspace, document, sandbox, profile, reflection and audit-oriented controls. The gateway is designed for MCP-capable hosts in general. Claude Desktop is a packaged and smoke-tested route, but the boundary remains useful when a host, such as ChatGPT Work, Claude or another MCP client, also offers its own file access or agent features.

PLwC is not production-certified. It is local infrastructure under active development.

What PLwC is - and what it is not

PLwC is:

reflection and Governor flows;

• an MCP gateway, not its own agent;
• a local governance boundary between model requests and tool execution;
• model- and host-independent policy for MCP-capable hosts;
• controlled memory, profile and persona management through explicit profile,

• a single public MCP boundary named plwc-gateway.

PLwC is not:

outside PLwC;

• a standalone AI platform;
• a desktop agent;
• the language model or a replacement for the user's chosen AI host;
• a full proxy for all model traffic;
• protection for data that a user or host sends directly to a cloud model

• permission to expose raw PLfC/PBA or Desktop Commander MCP servers beside the
