[MCP] Tool list costs ~100k tokens per chat — allow choosing a smaller toolset

💸 Quire MCP is too expensive to keep connected in clients that load all tools up front, so we had to turn it off for most of our team.

🚨 Problem

• 📦 The Quire MCP server exposes 107 tools, and every tool definition is sent to the model at the start of each chat.
• 📏 We measured about 100k input tokens for the Quire tool list alone in Codex/Cursor-style clients, before any task is read.
• 📝 Several descriptions are very long; search_tasks alone is over 5,000 characters with its schema.
• ⛔ In September we disabled Quire MCP for the team in Codex and Cursor because of this. Now we use it only in Claude Code, which loads tools on demand.

🛠️ Suggestion

• 🧰 Selectable toolsets via the connection URL or app settings, e.g. tasks (read, search, create, update, comment, move), read-only, and admin (dashboards, insights, statuses, fields, approvals, chats, documents).
• ✂️ Shorter descriptions: keep shared grammar (date filters, user boolean syntax) in one help tool or resource that the model opens only when needed.
• 🔒 A read-only option would also let teams hand the server to everyone safely.

ℹ️ Notes

• Our daily agent work uses about 15 tools: get/search/list tasks, create/update task, comments, move and status.
• Related to MCP hits rate limits too easy/often: both block wider team use of the MCP.
