Optional if set in ~/.cursor/mcp.json's mcpServers.substack-api.env.), SUBSTACK_USER_ID (Your Substack numeric user id. Optional if set in ~/.cursor/mcp.json.), SUBSTACK_SESSION_TOKEN (Your Substack session cookie value (the s%3A... string). Required for authenticated calls. Easier path: run `substack-ops auth login --browser chrome` and the cookie is auto-grabbed.), SUBSTACK_OPS_MCP_PATH (Override path to the mcp.json file the auth layer reads. Defaults to ~/.cursor/mcp.json.), SUBSTACK_OPS_LLM_CMD (Optional: override the host CLI used by the unattended daemon path (default: auto-detect claude / cursor-agent / codex on PATH). Use {prompt} placeholder if your CLI takes the prompt as an arg.). The author declared them in the registry entry; get the values from the project itself.
