MCP Proxy Server
by zDaniels437
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| PORT | No | Port for the proxy server's HTTP-based endpoints (`/sse`, `/mcp`, and Admin UI if enabled). Only used when running in a mode that starts an HTTP server. | 3663 |
| LOGGING | No | Optional. Controls the minimum log level output by the server. Possible values (case-insensitive): `error`, `warn`, `info`, `debug`. Default: `info`. | info |
| ALLOWED_KEYS | No | Comma-separated list of API keys to secure the proxy's HTTP-based endpoints (`/sse`, `/mcp`). Clients must provide a key via `X-Api-Key` header or `?key=` query parameter. If neither ALLOWED_KEYS nor ALLOWED_TOKENS are set, authentication is disabled. | |
| TOOLS_FOLDER | No | Optional. Specifies the base directory for Stdio server installations initiated via the Admin UI, used when `installDirectory` is not explicitly set in `mcp_server.json`. Defaults to a `tools` subdirectory within the proxy server's working directory if not set. | |
| ADMIN_PASSWORD | No | Password for Admin UI login. Required if Admin UI enabled. Default: `password` (Change this!). | password |
| ADMIN_USERNAME | No | Username for Admin UI login. Required if Admin UI enabled. Default: `admin`. | admin |
| ALLOWED_TOKENS | No | Comma-separated list of Bearer Tokens to secure the proxy's HTTP-based endpoints (`/sse`, `/mcp`). Clients must provide a token via the `Authorization: Bearer <token>` header. If both ALLOWED_KEYS and ALLOWED_TOKENS are configured, Bearer Token authentication is attempted first. | |
| SESSION_SECRET | No | Optional, recommended if Admin UI enabled. Secret used to sign session cookies. If not set, a secure secret is automatically generated and saved to `config/.session_secret` on first run. | |
| ENABLE_ADMIN_UI | No | Set to `true` to enable the Web Admin UI (only applicable in SSE mode). Default: `false`. | false |
| RETRY_SSE_TOOL_CALL | No | Optional. Controls whether to enable retries for SSE tool calls. Set to `"true"` to enable, `"false"` to disable. Default: `true`. | true |
| RETRY_HTTP_TOOL_CALL | No | Optional. Controls whether to retry on HTTP tool call connection errors. Set to `"true"` to enable, `"false"` to disable. Default: `true`. | true |
| RETRY_STDIO_TOOL_CALL | No | Optional. Controls whether to retry on Stdio tool call connection errors (attempts to restart the process). Set to `"true"` to enable, `"false"` to disable. Default: `true`. | true |
| SERVER_TOOLNAME_SEPERATOR | No | Optional. Defines the separator used to combine the server name and tool name when generating the unique key for tools. Default: `__`. Must be at least 2 characters long and contain only letters, numbers, hyphens, and underscores. | __ |
| SSE_TOOL_CALL_MAX_RETRIES | No | Optional. Maximum number of retry attempts for SSE tool calls (after the initial failure). Default: `2`. | 2 |
| HTTP_TOOL_CALL_MAX_RETRIES | No | Optional. Maximum number of retry attempts for HTTP tool calls (after the initial failure). Default: `2`. | 2 |
| STDIO_TOOL_CALL_MAX_RETRIES | No | Optional. Maximum number of retry attempts for Stdio tool calls (after the initial failure). Default: `2`. | 2 |
| SSE_TOOL_CALL_RETRY_DELAY_BASE_MS | No | Optional. Base delay in milliseconds for SSE tool call retries, used in exponential backoff. Default: `300`. | 300 |
| HTTP_TOOL_CALL_RETRY_DELAY_BASE_MS | No | Optional. Base delay in milliseconds for HTTP tool call retries, used in exponential backoff. Default: `300`. | 300 |
| STDIO_TOOL_CALL_RETRY_DELAY_BASE_MS | No | Optional. Base delay in milliseconds for Stdio tool call retries, used in exponential backoff. Default: `300`. | 300 |
