What You'll Need

Set these up before or after installing:

Persistent-state backend URL shared by every pvl-core subsystem that needs state. `memory://` is in-process and lost on restart; `file:///path` persists on one server; `redis://`, `dynamodb://` and `mongodb://` each need their matching extra. When unset, defaults to `file:///data/state` (the volume family Docker images mount), or to `memory://` (with a warning) on a host where that directory is not usable.Optional

Environment variable: SCHOLAR_MCP_KV_STORE_URL

Comma-separated explicit tool names this instance exposes; every other tool is hidden from listings and cannot be invoked. Names matching no registered tool are inert. Mutually exclusive with `tools_deny`. Takes effect through `apply_tool_visibility`.Optional

Environment variable: SCHOLAR_MCP_TOOLS_ALLOW

Comma-separated explicit tool names hidden from this instance (absent from listings, cannot be invoked). Names matching no registered tool are inert. Mutually exclusive with `tools_allow`. Takes effect through `apply_tool_visibility`.Optional

Environment variable: SCHOLAR_MCP_TOOLS_DENY

Rename this server instance; defaults to the project name.Optional

Environment variable: SCHOLAR_MCP_SERVER_NAME

Concise routing context that distinguishes this deployment's material or responsibility.Optional

Environment variable: SCHOLAR_MCP_INSTANCE_DESCRIPTION

Deployment-specific behavioral policy added to the generated MCP instructions.Optional

Environment variable: SCHOLAR_MCP_INSTRUCTIONS_EXTRA

Legacy: replaces all generated MCP instructions (deprecated; use _INSTANCE_DESCRIPTION for routing and _INSTRUCTIONS_EXTRA for policy).Optional

Environment variable: SCHOLAR_MCP_INSTRUCTIONS

Log level for FastMCP internals and app loggers (DEBUG / INFO / WARNING / ERROR / CRITICAL). The -v CLI flag overrides to DEBUG.Optional

Environment variable: FASTMCP_LOG_LEVEL

Set false for plain or structured JSON log output.Optional

Environment variable: FASTMCP_ENABLE_RICH_LOGGING

GitHub token used to raise rate limits when fetching standards documents from GitHub. Optional; unauthenticated requests work at reduced limits.Required

Environment variable: SCHOLAR_GITHUB_TOKEN

When true, write-tagged tools (PDF download and conversion cache writes) are hidden. Set false to enable them.Optional

Environment variable: SCHOLAR_MCP_READ_ONLY

Semantic Scholar API key. Optional but strongly recommended: unauthenticated requests are limited to ~1 req/s. Request one at https://www.semanticscholar.org/product/api#api-key-form.Required

Environment variable: SCHOLAR_MCP_S2_API_KEY

Base URL of a running docling-serve instance for PDF conversion (e.g. http://localhost:5001). When unset, PDF conversion tools return an error.Optional

Environment variable: SCHOLAR_MCP_DOCLING_URL

OpenAI-compatible VLM endpoint for formula and figure enrichment during PDF conversion.Optional

Environment variable: SCHOLAR_MCP_VLM_API_URL

API key for the VLM endpoint.Required

Environment variable: SCHOLAR_MCP_VLM_API_KEY

Model name to use with the VLM endpoint.Optional

Environment variable: SCHOLAR_MCP_VLM_MODEL

Directory for the SQLite cache database (cache.db) and downloaded PDFs (pdfs/, md/).Optional

Environment variable: SCHOLAR_MCP_CACHE_DIR

Contact email for the OpenAlex polite pool (improves rate limits). Also enables Unpaywall lookups as a PDF fallback source.Optional

Environment variable: SCHOLAR_MCP_CONTACT_EMAIL

EPO Open Patent Services consumer key. Optional; patent tools are hidden when unset. Register at https://developers.epo.org/user/register.Optional

Environment variable: SCHOLAR_MCP_EPO_CONSUMER_KEY

EPO Open Patent Services consumer secret. Optional; patent tools are hidden when unset.Required

Environment variable: SCHOLAR_MCP_EPO_CONSUMER_SECRET

Google Books API key. Optional; book tools work unauthenticated at reduced rate limits.Required

Environment variable: SCHOLAR_MCP_GOOGLE_BOOKS_API_KEY

Seconds a long-running tool call may run in the foreground before it is promoted to a background job and a job handle is returned instead.Optional

Environment variable: SCHOLAR_MCP_JOBS_SOFT_DEADLINE_S

Seconds a background-job record (working or finished) is retained for polling before it expires from the store.Optional

Environment variable: SCHOLAR_MCP_JOBS_RESULT_TTL_S

Maximum live background jobs per calling subject; further promotions are rejected until older records expire.Optional

Environment variable: SCHOLAR_MCP_JOBS_MAX_PER_SUBJECT

Public base URL of the deployed server, for example `https://mcp.example.com`. Required for OIDC. Also the fallback source of the MCP Apps domain when `app_domain` is unset.Optional

Environment variable: SCHOLAR_MCP_BASE_URL

Single shared bearer token; enables bearer auth unless `bearer_tokens_file` is set, which takes precedence.Required

Environment variable: SCHOLAR_MCP_BEARER_TOKEN

OIDC discovery document URL, for example `https://auth.example.com/.well-known/openid-configuration`.Optional

Environment variable: SCHOLAR_MCP_OIDC_CONFIG_URL

OIDC client identifier registered with the provider.Optional

Environment variable: SCHOLAR_MCP_OIDC_CLIENT_ID

OIDC client secret registered with the provider.Required

Environment variable: SCHOLAR_MCP_OIDC_CLIENT_SECRET

Expected `aud` claim; tokens issued for another audience are rejected.Optional

Environment variable: SCHOLAR_MCP_OIDC_AUDIENCE

Scopes a caller must present, space- or comma-separated. Defaults to `openid` in oidc-proxy mode.Optional

Environment variable: SCHOLAR_MCP_OIDC_REQUIRED_SCOPES

Scopes advertised to MCP clients in protected-resource metadata, space- or comma-separated. Overrides the default `openid offline_access`; `oidc_required_scopes` is always added on top. Set this when the registered client is not permitted `offline_access`, or to have clients request extra claim scopes (such as `groups`) without also requiring them in every token.Optional

Environment variable: SCHOLAR_MCP_OIDC_ADVERTISED_SCOPES

Signing key for issued tokens; used in oidc-proxy mode only. When unset, the key is derived deterministically from `oidc_client_secret`, so tokens survive a restart. Rotating that secret then invalidates every issued token. Set this explicitly to decouple token validity from secret rotation. Generate with `openssl rand -hex 32`.Required

Environment variable: SCHOLAR_MCP_OIDC_JWT_SIGNING_KEY

Validate the access token instead of the id token.Optional

Environment variable: SCHOLAR_MCP_OIDC_VERIFY_ACCESS_TOKEN

MCP Apps iframe domain, used for CSP sandboxing. Overrides the host derived from `base_url`.Optional

Environment variable: SCHOLAR_MCP_APP_DOMAIN

Explicit auth-mode override, accepting `remote` or `oidc-proxy` (case- and whitespace-insensitive). When unset the mode is auto-detected from which auth variables are set; the override exists because having all four OIDC variables set is ambiguous between those two modes. Other values are ignored with a warning.Optional

Environment variable: SCHOLAR_MCP_AUTH_MODE

Path to a TOML file mapping bearer tokens to subjects; overrides the single-token `bearer_token` mode.Optional

Environment variable: SCHOLAR_MCP_BEARER_TOKENS_FILE

Subject assigned to the single-token bearer mode; ignored when `bearer_tokens_file` is set, since mapped mode carries per-token subjects.Optional

Environment variable: SCHOLAR_MCP_BEARER_DEFAULT_SUBJECT

Mount path for the MCP endpoint; the health routes derive their prefix from it.Optional

Environment variable: SCHOLAR_MCP_HTTP_PATH

How much the unauthenticated /health and /health/ready bodies say: status, standard (adds name, version and per-check verdicts), or full (adds redacted reasons; trusted networks only).Optional

Environment variable: SCHOLAR_MCP_HEALTH_DETAIL

Run the server process as this UID; the container entrypoint reassigns ownership of writable paths to match.Optional

Environment variable: PUID

Run the server process as this GID; pair with PUID to match the owner of a mounted volume.Optional

Environment variable: PGID
