Problem
`TDLibClient.getChatHistory()` 已支援 `sinceDate`、`untilDate`、`maxMessages` 三個參數(含 bulk pagination 和 client-side date filtering),但 MCP Server 層(`Server.swift`)未將這些參數暴露給 MCP tool schema,呼叫端無法使用時間區間篩選或指定總筆數上限。
Type
feature
Expected
MCP tool `get_chat_history` 應支援:
`since_date` / `until_date`:ISO 8601 或 Unix timestamp,讓呼叫端篩選特定時間範圍的訊息
`max_messages`:指定總筆數上限,觸發 TDLibClient 的 bulk pagination 路徑自動翻頁
Actual
MCP tool 只暴露 `chat_id`、`limit`、`from_message_id` 三個參數。
已實作但未接上的 code:
`TDLibClient.swift:183-251`:三條路徑(backward-compat / single-page+date-filter / bulk pagination)
`Server.swift:345-351`:只傳了 `chatId`、`limit`、`fromMessageId`
Impact
想看「上週的對話」需要手動分頁 + 在 client 端過濾
長對話需要多次呼叫手動翻頁,無法一次指定「給我最多 200 則」
Library 層已經做好的功能白費了
Code Reference
MCP tool schema:`Server.swift:112-117`(缺少 `since_date` / `until_date` / `max_messages` 宣告)
MCP handler:`Server.swift:345-351`(未傳遞新參數給 `tdlib.getChatHistory()`)
Library 層已完成:`TDLibClient.swift:183-251`
Current Status
Phase : closed
Last updated : 2026-04-16 by idd-close
Key Decisions
Pure wiring: TDLibClient already had sinceDate/untilDate/maxMessages; only Server.swift needed changes
MCP params: since_date and until_date as YYYY-MM-DD, max_messages as integer
Reused existing parseISODate() helper — consistent with dump_chat_to_markdown
Spec updated from 'thin wrapper (3 params)' to '6 params with auto-pagination'
Verification: 6-AI cross-review PASS, Codex flagged until_date semantics → 日期處理改善: until_date 語義偏差 + parseISODate 靜默 nil #5
