Implementation Reference
- mcp-server.js:144-156 (handler)Handler function that reloads environment variables using loadEnvMulti, rebuilds authentication and base URL from env vars, and returns the current configuration status.
"elfa_reload_env": async () => { loadEnvMulti(); ELFA_AUTH = buildAuthFromEnv(); ELFA_BASE = (process.env.ELFA_BASE || ELFA_BASE).replace(/\/+$/,""); return { content: textContent({ ok: true, base: ELFA_BASE, loaded: ENV_INFO.loaded, from: ENV_INFO.from, vars: ENV_INFO.vars, auth: { headerName: ELFA_AUTH.headerName || "", scheme: ELFA_AUTH.scheme || "", key: maskKey(ELFA_AUTH.key) } }) }; }, - mcp-server.js:276-280 (registration)Tool registration entry in the tools array, providing name, description, empty input schema (no parameters), and annotations.
{ name:"elfa_reload_env", description:"Reload .env files from common locations.", inputSchema:{ type:"object", properties:{} }, annotations:{ title:"ELFA: Reload .env", readOnlyHint:false, openWorldHint:false } }, - mcp-server.js:32-58 (helper)Key helper function called by the handler to load .env files from multiple possible locations (cwd, __dirname, parent dirs), updates ENV_INFO, and logs the result.

function buildAuthFromEnv() { const envKey = process.env.ELFA_API_KEY || ""; let header = (process.env.ELFA_HEADER || "x-elfa-api-key").toLowerCase(); // default to x-elfa-api-key if (header !== "x-elfa-api-key" && header !== "authorization") { header = "x-elfa-api-key"; } if (header === "authorization") { return { headerName: "Authorization", scheme: "Bearer", key: envKey }; } return { headerName: "x-elfa-api-key", scheme: "", key: envKey }; }
