### Description (declared)

# ews-mcp-orf

MCP server for an on-premises Microsoft Exchange mailbox via EWS — a lean,
safety-gated tool surface for LLM assistants: capability tiers, send
kill-switch, two-phase content-bound send confirmation, recipient guard,
and a hash-chained audit log.

> This is the internally packaged distribution of
> [`azizmazrou/ews-mcp`](https://github.com/azizmazrou/ews-mcp) (MIT).
> It carries local hardening patches (attachment size cap, recipient
> canonicalization, audit fail-closed, persistent confirm tokens,
> system-trust TLS). Full architecture and development docs live in the
> source repository.

## Install & run (stdio — the default)

Requires [uv](https://docs.astral.sh/uv/) (a single EXE; it manages its
own Python) — no Docker, no venv, no checkout:

```bash
uvx --from ews-mcp-orf ewsmcp
```

Pin a version for pilot deployments:

```bash
uvx --from ews-mcp-orf==4.5.0a1.post1 ewsmcp
```

**Claude Code** (one command, then restart the session):

```bash
claude mcp add exchange \
  -e EWS_SERVER_URL="https://mail.example.com/EWS/Exchange.asmx" \
  -e EWS_EMAIL="user@example.com" \
  -e EWS_USERNAME="DOMAIN\\user" \
  -e EWS_PASSWORD="…" \
  -e EWS_CAPABILITY_TIER="read" \
  -e SEND_ENABLED="false" \
  -e EWS_TZ="Europe/Vienna" \
  -- uvx --from ews-mcp-orf ewsmcp
```
On Windows, Integrated Authentication is available as an explicit opt-in:

```bash
EWS_AUTH_MODE=process \
EWS_SERVER_URL="https://mail.example.com/EWS/Exchange.asmx" \
EWS_EMAIL="user@example.com" \
uvx --from ews-mcp-orf ewsmcp
```

This uses the current Windows logon token through SSPI and does not use
`EWS_USERNAME` or `EWS_PASSWORD`. The default `EWS_AUTH_MODE=credentials`
remains portable across Windows, Linux and macOS.

**Claude Desktop** — add to `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "exchange": {
      "command": "uvx",
      "args": ["--from", "ews-mcp-orf", "ewsmcp"],
      "env": {
        "EWS_SERVER_URL": "https://mail.example.com/EWS/Exchange.asmx",
   …
