Title: Community plugin: GLM Coding Plan (Z.ai) inside DeepSeek Harness — web_search/web_fetch providers, vision/zread MCP tools, quota chip

Body:

Hi! I built a community plugin that plugs a GLM Coding Plan (Z.ai) subscription into DeepSeek Harness, using only the public dsh plugin seams (ctx.credentials, ctx.web, ctx.webServer, ctx.slots, dsh-mcp-client):

Repo: https://github.com/FamousMonsterr/zai-web-search-mcp (MIT, zero npm dependencies)
npm: dsh-zai-web-search-mcp

What it does:

1. web_search runs through the Z.ai web_search_prime MCP server (registered as a ctx.web search provider, id zai-mcp) — a drop-in replacement backend for the built-in tool.
2. web_fetch runs through the Z.ai web_reader MCP server (a ctx.web fetch provider, id zai-reader) — server-side fetching with structured markdown extraction.
3. Standalone MCP tools: mcp__zai__web_search_prime, mcp__zai-reader__webReader, mcp__zai-zread__search_doc/read_file/get_repo_structure (GitHub repo analysis), and 8 mcp__zai-vision__* image/video tools (local stdio @z_ai/mcp-server) — the vision tools work for text-only models since the server returns text for a file path.
4. A quota chip in the composer stats row: 5-hour & weekly credit windows + MCP calls in the last 30 days (the Z.ai monitoring API), localized en/ru/zh.
5. The API key never appears in config or the browser: the plugin resolves ZAI_API_KEY through ctx.credentials and hot-reloads on credentials/reference-updated.

If the maintainers are interested, the interesting bits for dsh itself: the plugin shows a full third-party bundle flow (Host plugin + client module + dsh.bundle.patch auto-activation from npm, engines.dsh gating) and could serve as a reference implementation for third-party web providers and MCP bridges. Feedback and issues welcome — happy to contribute improvements back.

Take it and use it if you have a GLM Coding Plan: install dsh-zai-web-search-mcp from npm via the Plugins page (or ask your agent to install it), store ZAI_API_KEY in the credentials surface, restart. ⭐
