Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| POSTHOG_HOST | No | Override the PostHog host for anonymous telemetry, such as for a self-hosted PostHog deployment. | https://us.i.posthog.com |
| POSTHOG_API_KEY | No | Override the PostHog project write key used for anonymous telemetry. Set to an empty string to skip PostHog client initialization. | |
| WINDOWS_MCP_DEBUG | No | Set to 1, true, yes, or on to enable debug mode, which sets the log level to DEBUG for verbose output. Also available as the --debug CLI flag. | false |
| WINDOWS_MCP_TOOLS | No | Comma-separated explicit list of tools to enable (e.g., Screenshot,Click,Snapshot). Alternative to --tools CLI flag. | |
| WINDOWS_MCP_CALLLOG | No | Call log path, or off to disable it | ~/.windows-mcp/calls.log |
| WINDOWS_MCP_JOB_DIR | No | Where job output files are written | ~/.windows-mcp/jobs |
| ANONYMIZED_TELEMETRY | No | Set to false to disable anonymous usage telemetry. No personal data, tool arguments, or outputs are ever collected regardless of this setting. | true |
| WINDOWS_MCP_AUTH_KEY | No | Bearer token required on all HTTP requests. Alternative to --auth-key CLI flag. | |
| WINDOWS_MCP_WATCHDOG | No | Set to off, 0, false, no, or disabled to disable the UIA focus watchdog that keeps the accessibility tree current. On unstable UIA environments the watchdog can degrade after long uptime (e.g. across a sleep/resume or session change); disabling it trades away automatic focus tracking for stability — the accessibility tree still refreshes on-demand for tool calls. | true |
| WINDOWS_MCP_SSL_KEYFILE | No | Path to TLS private key file (.pem) for HTTPS. Must be provided with WINDOWS_MCP_SSL_CERTFILE. | |
| WINDOWS_MCP_CORS_ORIGINS | No | Comma-separated list of origins permitted to make cross-origin browser requests (e.g., https://my-client.example.com). No CORS headers are emitted when unset. Alternative to --cors-origins CLI flag. | |
| WINDOWS_MCP_IP_ALLOWLIST | No | Comma-separated list of allowed client IPs or CIDR ranges (e.g., 203.0.113.0/24,198.51.100.5). Alternative to --ip-allowlist CLI flag. | |
| WINDOWS_MCP_SSL_CERTFILE | No | Path to TLS certificate file (.pem) for HTTPS. Must be provided with WINDOWS_MCP_SSL_KEYFILE. | |
| WINDOWS_MCP_DISABLE_FLASH | No | Set to 1, true, yes, or on to suppress the orange-red glowing border that briefly highlights the captured area after every screenshot. | |
| WINDOWS_MCP_EXCLUDE_TOOLS | No | Comma-separated list of tools to disable (e.g., PowerShell,Registry). Alternative to --exclude-tools CLI flag. | |
| WINDOWS_MCP_STATELESS_HTTP | No | Set to 1, true, yes, or on to run streamable-http without Mcp-Session-Id connection state. Useful for reconnects after restarts and for horizontally scaled deployments. | false |
| WINDOWS_MCP_CALLLOG_BACKUPS | No | Older generations to keep | 3 |
| WINDOWS_MCP_OAUTH_CLIENT_ID | No | OAuth client ID for HTTP transports. Must be provided with WINDOWS_MCP_OAUTH_CLIENT_SECRET. | |
| WINDOWS_MCP_JOB_RETURN_AFTER | No | Seconds a call waits before handing a command over as a job (capped at 225) | 200 |
| WINDOWS_MCP_PROFILE_SNAPSHOT | No | Set to 1, true, yes, or on to emit per-stage timing logs for Screenshot/Snapshot calls. Useful for diagnosing slow captures. | |
| WINDOWS_MCP_SCREENSHOT_SCALE | No | Scale factor applied to screenshots before encoding. Accepts a float in the range 0.1–1.0. Useful on high-resolution displays (1440p, 4K) where the default produces images that exceed Claude Desktop's 1 MB tool-result limit. Set to 0.5 to halve both dimensions (quarter the file size). | 1.0 |
| WINDOWS_MCP_CALLLOG_MAX_BYTES | No | Rotation threshold in bytes | 1000000 |
| WINDOWS_MCP_SCREENSHOT_BACKEND | No | Screenshot capture backend. Accepted values: auto (tries dxcam → mss → pillow in order), dxcam, mss, pillow. Use mss or pillow if dxcam is unavailable or causes issues on your GPU. | auto |
| WINDOWS_MCP_OAUTH_CLIENT_SECRET | No | OAuth client secret for HTTP transports. Must be provided with WINDOWS_MCP_OAUTH_CLIENT_ID. |
