### Description (declared)

# Zero Harm AI MCP

Zero Harm AI MCP is a Model Context Protocol server that lets AI agents and runtime firewalls call Zero Harm AI safety checks for text, chat messages, prompts, tool inputs, and generated outputs.

The server is a thin adapter over `zero-harm-ai-detectors`. It should not duplicate detector logic from the detector package or from the Zero Harm AI GitHub Action.

## Goals

- Expose PII, secret, and harmful-content detection through MCP tools.
- Return structured findings that agents and firewalls can enforce.
- Support local/self-hosted operation for sensitive data.
- Keep logs privacy-safe by default.
- Provide stable tool contracts that can be used by coding agents, chat agents, and firewall.

## Non-Goals

- Reimplementing `zero-harm-ai-detectors`.
- Acting as a hosted service by default.
- Making policy enforcement decisions that belong to a firewall or calling agent.
- Replacing the Zero Harm AI GitHub Action.

## Relationship To Other Projects

```text
zero-harm-ai-detectors
  Shared detector engine for PII, secrets, and harmful content.

zero-harm-ai-gh-action
  GitHub Action and CI-oriented scanner for pull requests.

zero-harm-ai-mcp
  MCP server adapter that exposes detector functionality to AI agents.

zero-harm-ai-firewall (future)
  Runtime enforcement layer. It can call zero-harm-ai-mcp or use
  zero-harm-ai-detectors directly.
```

## MCP Tools

### `zero_harm.scan_text`

Scan one text string for PII, secrets, and harmful content.

Use this for prompt inputs, generated outputs, tool arguments, logs, and arbitrary text.

### `zero_harm.scan_messages`

Scan chat-style messages while pr…
