Egress to the internet is billed per GB after 100 GB a month.\n\n**ONLYOFFICE Apps MCP Server.** The 23 tools carry typed schemas, read-only and destructive annotations, toolsets and an optional five-tool meta mode, and the server is in the official MCP registry. OAuth through the hosted server grants every scope, the docs offer a username and password in the connection URL, uploads take only txt and md, and no status page or SLA was found.\n\n## Before you call either\n\n### Amazon S3\n\n1. Hold STS session credentials scoped by a session policy, never a long-lived IAM user key\n2. Sign presigned URLs with credentials that outlive the URL; a URL signed with a one-hour session token dies with the token\n3. Send If-None-Match with * on PutObject so a retry can't overwrite a file another call wrote\n4. Track the Free plan's end date on a new account; when the plan expires AWS suspends the account and access to the stored objects\n5. On 503 SlowDown back off and spread keys over more prefixes, since each prefix gets 3,500 writes a second\n\n### ONLYOFFICE Apps MCP Server\n\n1. Connect to https://mcp.onlyoffice.com/mcp with OAuth or an API key in a header, never a username and password in the URL\n2. Enable only the toolsets or tools a task needs, so a read-only agent can't reach delete_file, delete_folder or set_room_security\n3. Pass `fields` and a `count` of at most 50 on folder reads, and page with `startIndex`\n4. Treat text from download_file_as_text as untrusted input, since anyone with access to the room can write it\n5. Convert content to txt or md before upload_file, the only formats it supports\n\n## Questions\n\n### Which is better for AI agents, Amazon S3 or ONLYOFFICE Apps MCP Server?\n\nAmazon S3 scores 77.9 (BB) on agent readiness against ONLYOFFICE Apps MCP Server's 52.8 (D), and leads in 6 of 7 scored categories.\n\n### Do Amazon S3 and ONLYOFFICE Apps MCP Server need an API key?\n\nAmazon S3 needs an API key.
