OOneUptime MCP (official, remote)

Context cost warning: its tools/list is about 218,440 tokens (223 tools), 667% of a 32k context window and 109% of a 200k window, before you send a single message (raw tools/list payload 224,598 tokens). Load only the tools you need, or expect most of the context to go to tool definitions. Measured by counting the tokens in this server's tool list on 2026-11-02. How MCP context cost adds up

OneUptime's hosted endpoint https://oneuptime.com/mcp (server oneuptime-mcp 14.0.98; source in the OneUptime/oneuptime monorepo) completed initialize and tools/list with no sign-in and listed 223 tools (create/get/list/update/delete/count for each OneUptime resource). Calls need an account: count_teams was refused with 'Authentication is required for this tool. Sign in with OneUptime, or send a OneUptime API key in the x-api-key header.' (live endpoint probe, Nov 2, 2026). License: Apache-2.0, from the repo's LICENSE file, which covers everything outside the ee/ directory; the MCP server lives outside ee/. The npm package @oneuptime/mcp-server 9.2.22 was not tested. Score capped: no passing tool call.
