xfy 9eac025b3e feat(mcp): 完整工具面 + token 管理 + 管理页(T2-T5 并行实现 + 合并)
T2 token 管理(src/api/mcp_tokens.rs):create/list/reveal/revoke + get_mcp_client_configs
服务端函数,均经 get_current_admin_user 鉴权;TokenLifetime 枚举(1/7/30/90天/永不过期)。
src/mcp/config.rs 生成 4 种客户端配置(Claude Code/Cursor/Cline/通用 + CLI)。
src/pages/admin/mcp.rs 令牌管理页:列表 + 新建表单 + 一次性明文展示/重查 + 撤销 +
配置片段卡片。路由 /admin/mcp,导航项加入 admin_layout。

T3 read 工具 + Resources(tools/read.rs, resources.rs):search_posts/get_post/list_tags
(read 作用域,仅已发布);published-post Resources(post://{slug},游标分页)。
search_published 提取为共享函数。

T4 write 工具(tools/{posts,comments,tags,media}.rs):create/update/publish/trash/delete_post、
评论审核、标签 CRUD、媒体 base64 上传(WebP 转码 + 去重)。复用既有 helper 的 SQL 与
缓存失效(moka + ssr_cache)。write 作用域,可读草稿。

T5 admin 工具(tools/{settings,runner}.rs):get/update_settings、run_code(沙箱执行)。
admin 作用域。

合并(server.rs):用 rmcp tool_router 的「命名路由 + 组合」模式,7 个工具组在
YggMcpServer 上 impl,combined_router 用 + 合并成单一 ServerHandler。各工具组鉴权
独立,经 Extension<Parts> 读 McpPrincipal + scope.grants 校验。

新增依赖 base64 0.22(媒体上传解码)。验证:server/web 双目标编译通过、clippy
--all-features -D warnings 干净、659 单测 + 1 集成全绿(+20 新测试)。

T4 — write-scope tools (post CRUD, comments, tags, media)

Blocking edges

  • Blocks: T6 (hardening covers these).
  • Blocked by: T1 (mount + auth + dispatch exist).

Target files

  • src/mcp/tools/posts.rs, src/mcp/tools/comments.rs, src/mcp/tools/tags.rs, src/mcp/tools/media.rs — new.
  • src/mcp/server.rs — register write tools (scope-gated).

Change

Reuse existing server-fn / helper logic — do NOT duplicate business rules. Each write tool calls the same helpers the web admin uses, then runs the same cache invalidation (moka invalidate_* + ssr_cache::invalidate_ssr_*).

  1. Posts: create_post, update_post, publish_post, trash_post, delete_post. write/admin scope. These tokens MAY read drafts (decision 7). create_post must spawn_blocking(render_markdown_enhanced) and persist content_html, exactly like src/api/posts/create.rs.
  2. Comments: list_comments, approve_comment, delete_comment, set_comment_status — delegate to src/api/comments/* helpers.
  3. Tags: create_tag, rename_tag — delegate to src/api/posts/tags.rs.
  4. Media: upload_media(filename, base64, alt?) — feed the existing upload pipeline (src/api/upload.rs); return the served URL for embedding in posts.

Acceptance

  • A write-token create_post writes a row, renders content_html, and invalidates the matching moka + SSR caches (web admin sees the new post immediately).
  • A read token calling any write tool → insufficient_scope rejection.
  • write/admin tokens can read drafts via get_post; read tokens cannot.
  • Media upload returns a usable image URL consumable in post body.
  • Both targets compile; clippy clean; existing tests pass.
