MCP Station

The MCP app store for DeepSeek Harness: curated catalog, one-click install, health checks and browser presets.

MCP Station solves three concrete problems for DSH users:

1. Find it and configure it: most MCP managers are CRUD panels; installing Playwright still means hand-writing JSON and fighting Chromium revisions. MCP Station ships a curated catalog, writes the config, connects, and runs a smoke check.
2. Slow markets: the default market index goes through jsDelivr and often takes 15-25s or times out in mainland China. The MCP Station catalog is bundled with the plugin and works offline.
3. Did it actually work?: every entry can be tested (initialize + tools/list) with tool count, latency and error details. The Playwright preset detects local Chrome and adds --browser chrome for you.

What's new in 0.1.1

• Custom MCP servers: stdio (command/args/env) or HTTP (url/headers), with validation and a test button.
• Import JSON: paste Claude / Cursor mcpServers configs or a servers array; invalid or duplicate entries are skipped with reasons.
• Auto-test after install: initialize + tools/list immediately, showing status, tool count and errors; can be disabled in Settings.

Features

• Curated store: browser, search, dev, data, memory and productivity categories, bilingual copy and risk labels.
• One-click install: writes a managed block into the active profile cordis.patch.yml; DSH HMR loads it in seconds.
• Connectivity test with tool count, latency and errors; Playwright’s first test downloads the server into the npm cache under DSH Home.
• Browser preset that detects Chrome/Chromium and avoids missing bundled Chromium revisions.
• Safety: risk levels, secret redaction, env references that never persist secrets, read-only external rows, YAML validation + atomic replace + 3 backups.
• Environment doctor: profile, patch path, DSH version, Chrome, Playwright cache.

Install

Desktop: Settings → Plugins → Add plugin → enter dsh-mcp-station → Install → restart/refresh.

CLI:

dsh plugin --profile web add dsh-mcp-station

Usage

1. Open MCP Station → Store.
2. Pick Playwright Browser → Install (already carries --browser chrome).
3. In Installed, click Test connection. The first run downloads @playwright/mcp (~30s); then you should see Connected and 25 tools.
4. Go back to the conversation and ask the agent to open a page.
