One config entry that exposes every tool of the five servers. It starts the time tracker, price tracker, spreadsheet, invoice and expense tracker as child processes and exposes every tool, resource and prompt under one server, with one license pair.
One entry rather than five, and the arithmetic is worth doing: 49 tools against Cascade's ceiling of 100 leaves room for roughly one more server of this size, not four.
| You say | Tool |
|---|---|
| Start a timer for Acme. | timer_start |
| Now invoice Acme for this week's hours and the rebillable expenses, 23% VAT, due in 14 days, PDF. | six calls, entry_list through invoice_pdf |
| What did I spend this month and what is still unbilled? | expense_list and entry_list |
Its startup line reads: proxying [time-tracker, price-tracker, spreadsheet, invoice, expense-tracker], 49 tools. Those three sentences are consecutive turns of one audited conversation that scored 12 out of 12.
The file is mcp_config.json, and the key inside it is mcpServers.

}Save and reopen the MCP Servers list; Cascade picks it up without restarting the editor.
The npm publish of @theluckystrike/mcp-office-suite is pending; until then use the .mcpb bundle or a clone and build from the latest release.
The suite starts five child processes, so it has no hosted form. Each of the five is served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP instead: mint a free token with curl https://mcp.zovo.one/mcp/token, or use a Pro key as the bearer.
Read this first: mcp_config.json applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, takes its servers from the Devin CLI config files, so a correct entry here can still be invisible in a fresh tab. The other hard number is a cap: Cascade reaches at most 100 tools at once, and every enabled server spends from it.
Free: each child keeps its own free tier. Pro is $39 once, verified offline.
~/.codeium/windsurf/mcp_config.json, under mcpServers. Reach it from the MCPs icon at the top right of the Cascade panel, or Devin Settings, Cascade, MCP Servers.
That file applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, reads its servers from the Devin CLI config files instead. Check which agent the tab runs.
Cascade reaches at most 100 tools at any one time, and every enabled server spends from that single budget. MCP Office Suite contributes 51 tools, so keep the enabled list short rather than counting servers.
