Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| MCP_HOST | No | Bind address for streamable-http transport. Default: 127.0.0.1. | 127.0.0.1 |
| MCP_PORT | No | Port for streamable-http transport. Default: 8000. | 8000 |
| MCP_TRANSPORT | No | Transport mode: 'stdio' (default) or 'streamable-http'. | stdio |
| MCP_PUBLIC_URL | No | Externally-visible base URL. When set, enables OAuth 2.1. Leave unset for local stdio use. | |
| MCP_ALLOWED_HOSTS | No | Comma-separated Host headers to accept (DNS-rebinding protection). Required when behind a reverse proxy. | |
| MCP_AUTH_STATE_PATH | No | Where to persist OAuth clients/tokens. Default: oauth-state.json beside server.py. | oauth-state.json |
| SEMANTIC_SCHOLAR_API_KEY | No | A personal Semantic Scholar API key. Without one, S2 calls fall back to the shared unauthenticated rate limit, which is slower and more prone to 429 errors. All other functionality works unaffected. | |
| PAPER_SEARCH_CONTACT_EMAIL | No | Sent as a mailto: contact to get polite pool (faster, more reliable) treatment from CrossRef and OpenAlex. Required by get_open_access_pdf (Unpaywall rejects requests with no email). |
