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. Default: 3663. | 3663 |
| LOGGING | No | Optional minimum log level output by the server. Possible values (case-insensitive): error, warn, info, debug. Default: info. | 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 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 target ${TOOLS_FOLDER}/<server_key>; otherwise they default to ./tools/<server_key>. The Dockerfile sets this to /tools by default. | |
| ADMIN_PASSWORD | No | Required if Admin UI enabled. Password for Admin UI login. Default: password (change this!). | password |
| ADMIN_USERNAME | No | Required if Admin UI enabled. Username for Admin UI login. Default: admin. | 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 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 | 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 separator used to combine the server name and tool name when generating the unique key for tools (e.g., server-key__tool-name). Must be at least 2 characters long and contain only letters, numbers, hyphens, and underscores. If invalid, the default (__) is used and a warning is logged. | __ |
| 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 |

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
