EVE Online OSINT MCP Server

Instructions

Implementation Reference

• src/server.ts:752-857 (handler)

  The execute handler for the corporation-osint tool. Resolves the corporation name to ID using ESI search, fetches detailed corporation information from ESI (including member count, tax rate, CEO, etc.), retrieves member list and stats from EveWho API, and compiles a markdown-formatted OSINT report.
  execute: async (args, { log }) => { try { log.info("Resolving corporation name to ID", { corporationName: args.corporationName, }); // Resolve corporation name to ID const resolved = await resolveNamesToIds([args.corporationName]); if (!resolved.corporations || resolved.corporations.length === 0) { return `Corporation "${args.corporationName}" not found. Please check the spelling and ensure it's an exact match.`; } const corporation = resolved.corporations[0]; log.info("Corporation resolved", { id: corporation.id, name: corporation.name, }); // Get corporation information from multiple sources log.info("Fetching corporation data from multiple sources", { corporationId: corporation.id, }); const [esiCorpInfo, eveWhoCorpData] = await Promise.allSettled([ getESICorporationInfo(corporation.id), getCorporationMembers(corporation.id), ]); let result = `# Corporation OSINT Report: ${corporation.name}\n\n`; result += `**Corporation ID:** ${corporation.id}\n`; result += `**Corporation Name:** ${corporation.name}\n\n`; // ESI Corporation Information if (esiCorpInfo.status === "fulfilled") { const esiInfo = esiCorpInfo.value; result += `## ESI Corporation Information\n`; result += `**Name:** ${esiInfo.name}\n`; result += `**Ticker:** ${esiInfo.ticker}\n`; result += `**Member Count:** ${esiInfo.member_count}\n`; result += `**Tax Rate:** ${(esiInfo.tax_rate * 100).toFixed(1)}%\n`; if (esiInfo.date_founded) { result += `**Founded:** ${esiInfo.date_founded}\n`; } if (esiInfo.alliance_id) { result += `**Alliance ID:** ${esiInfo.alliance_id}\n`; } result += `**CEO ID:** ${esiInfo.ceo_id}\n`; result += `**Creator ID:** ${esiInfo.creator_id}\n`; if (esiInfo.description) { result += `**Description:** ${esiInfo.description}\n`; } if (esiInfo.url) { result += `**URL:** ${esiInfo.url}\n`; } if (esiInfo.war_eligible !== undefined) { result += `**War Eligible:** ${esiInfo.war_eligible ?
