本地 MCP 插件：agent 接到新任务时，从本地已安装的全部 skill（用户级/插件级/项目级）中检索 Top-N 推荐。只推荐不执行。
索引方法来自 SkillRouter（arXiv 2603.22455）：all-field 分段多向量（name+description 一个向量 + 正文 ~800 字符切块各一个向量），查询对每块算余弦、skill 得分取 max-pool。
工具 | 用途 |
| 任务开始前检索最相关 skill；返回 score、tier（auto/prompt/skip，参考值）、调用名与路径 |
| 安装/删除 skill 后增量重建索引（mtime diff），无需重启会话 |

claude mcp add fastroute -- node /absolute/path/to/fastroute/dist/index.js数据目录 ~/.fastroute（FASTROUTE_DATA_DIR 覆盖）：fastroute.db、config.json、models/
embedding 模型：Xenova/paraphrase-multilingual-MiniLM-L12-v2（q8，约 135MB），首次调用工具时联网下载，默认 ModelScope 镜像（FASTROUTE_EMBEDDING_HOST 可指回 https://huggingface.co）；已有 ~/.knowyoubetter/models 缓存时直接复用
模型是硬依赖：离线且无缓存时工具返回错误与下载指引，无词法降级
config.json 可覆盖：chunkSize(800)、autoThreshold(0.9)、promptThreshold(0.6)、topK(5)、userSkillsDir、pluginCacheDir、projectSkillsEnabled
修改 chunkSize 后已有索引不会自动重切：需删除 ~/.fastroute/fastroute.db 再调用 reindex_skills

MCP Server for an Agent Task Marketplace
The CustomGPT.ai MCP server is a fully managed, RAG-powered endpoint that connects large language models with private knowledge bases and external data sources. It provides tools for retrieval-augmented generation queries (send_message), data ingestion (upload_file), and source listing, enabling AI agents to query private documents like PDFs with high accuracy and real-time citations.
Fastio gives your team and AI agents a workspace for each project, bringing source files, comments and new work together. Connect a compatible MCP client to find files, answer questions from project material, and save results where the team can review and use them. \ Sign in through Fastio and choose the workspaces the connection can reach. Read Only connections expose read tools; Read & Write connections also allow changes. \ • **Files and folders:** browse, read, upload, and organize files, with version history and trash. • **Search:** find files by keyword; search file content and meaning when Deep Indexing is enabled and files have been processed. • **Metadata:** read, set, and search metadata fields, including extracted fields where available. • **Shares:** create and manage shares for sending or collecting files. • **Comments and members:** read and add comments, and manage workspace membership within your permissions. • **Activity:** search workspace events to see what changed. \ Hosted by Fastio, with no server installation required. \ • **Claude and most MCP clients:** https://mcp.fast.io/mcp/tools • **ChatGPT:** https://mcp.fast.io/mcp/operations • **ChatGPT and Codex:** Fastio plugin • **Claude Code, Cursor and similar coding agents:** https://mcp.fast.io/mcp/code • **Setup and client-specific capabilities:** https://mcp.fast.io/docs \ Paid plans. Monthly plans include a trial of up to 30 days. A card is required, and billing begins when the trial ends or trial credits run out, whichever comes first. No free plan.
