MCP Proxy Server
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 (e.g., via `npm run dev:sse` or the Docker container). The `npm run dev` script runs in Stdio mode. | 3663 |
| LOGGING | No | (Optional) Controls the minimum log level output by the server. Possible values (case-insensitive): `error`, `warn`, `info`, `debug`. Logs at the specified level and all levels above it will be shown. | info |
| ALLOWED_KEYS | No | (Optional) Comma-separated list of API keys to secure the proxy's HTTP-based endpoints (`/sse`, `/mcp`). If neither `ALLOWED_KEYS` nor `ALLOWED_TOKENS` are set, authentication is disabled for these endpoints. Clients must provide a key via `X-Api-Key` header or `?key=` query parameter. | |
| 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` for a specific server. If set, installations for servers without a specific `installDirectory` will target a subdirectory named after the server key within this folder (e.g., `${TOOLS_FOLDER}/<server_key>`). If not set or empty, such installations default to a `tools` subdirectory within the proxy server's working directory (e.g., `./tools/<server_key>`). The Dockerfile sets this to `/tools` by default. | |
| ADMIN_PASSWORD | No | Password for Admin UI login. Required if the Admin UI is enabled. Change this! | password |
| ADMIN_USERNAME | No | Username for Admin UI login. Required if the Admin UI is enabled. | admin |
| ALLOWED_TOKENS | No | (Optional) Comma-separated list of Bearer Tokens to secure the proxy's HTTP-based endpoints (`/sse`, `/mcp`). If neither `ALLOWED_KEYS` nor `ALLOWED_TOKENS` are set, authentication is disabled. Clients must provide a token via the `Authorization: Bearer <token>` header. If both `ALLOWED_KEYS` and `ALLOWED_TOKENS` are configured, Bearer Token authentication will be attempted first. | |
| SESSION_SECRET | No | (Optional, recommended if Admin UI enabled) Secret used to sign session cookies. If not set, a default, less secure secret is used, and a warning is issued. A secure secret is automatically generated and saved to `config/.session_secret` on first run if not provided via environment variable. | |
| ENABLE_ADMIN_UI | No | (Optional) Set to `true` to enable the Web Admin UI (only applicable in SSE mode). | false |
| RETRY_SSE_TOOL_CALL | No | (Optional) Controls whether to enable retries for SSE tool calls. Set to `"true"` to enable, `"false"` to disable. | 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. | 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. | 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 (e.g., `server-key__tool-name`). This key is used internally and in the `tool_config.json` file. Must be at least 2 characters long and contain only letters (a-z, A-Z), numbers (0-9), hyphens (`-`), and underscores (`_`). If the provided value is invalid, the default (`__`) will be used, and a warning will be logged. | __ |
| SSE_TOOL_CALL_MAX_RETRIES | No | (Optional) Maximum number of retry attempts for SSE tool calls (after the initial failure). | 2 |
| HTTP_TOOL_CALL_MAX_RETRIES | No | (Optional) Maximum number of retry attempts for HTTP tool calls (after the initial failure). | 2 |
| STDIO_TOOL_CALL_MAX_RETRIES | No | (Optional) Maximum number of retry attempts for Stdio tool calls (after the initial failure). | 2 |
| SSE_TOOL_CALL_RETRY_DELAY_BASE_MS | No | (Optional) Base delay in milliseconds for SSE tool call retries, used in exponential backoff. | 300 |
| HTTP_TOOL_CALL_RETRY_DELAY_BASE_MS | No | (Optional) Base delay in milliseconds for HTTP tool call retries, used in exponential backoff. | 300 |
| STDIO_TOOL_CALL_RETRY_DELAY_BASE_MS | No | (Optional) Base delay in milliseconds for Stdio tool call retries, used in exponential backoff. | 300 |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
