@lphal/deepseek-tool-search

An npx-friendly MCP server exposing DeepSeek-backed web_search and web_fetch tools.

The default path calls DeepSeek's dedicated Search and Fetch APIs without an auxiliary model response. An optional Messages-compatible search mode mirrors DeepSeek Harness's legacy web_search_20250305 server-tool flow.

Quick Start

Requires Node.js 20.19 or newer.

The development toolchain is pinned to pnpm@10.23.0 and typescript@6.0.3.

{
  "mcpServers": {
    "deepseek-search": {
      "command": "npx",
      "args": ["-y", "@lphal/deepseek-tool-search"],
      "env": {
        "DEEPSEEK_API_KEY": "sk-your-key"
      }
    }
  }
}

This is a stdio MCP server. The MCP client starts it through npx; the DeepSeek REST URL is not used as an HTTP/SSE MCP endpoint.

After publishing, register it with Codex CLI:

codex mcp add deepseek-search \
  --env DEEPSEEK_API_KEY="$DEEPSEEK_API_KEY" \
  -- npx -y @lphal/deepseek-tool-search

codex mcp list shows the configured server. The --env option writes the key into the Codex MCP configuration, so use your client's preferred secret-injection mechanism if local persistence is unsuitable.

Local development:

pnpm install
pnpm build
pnpm start -- --check
pnpm test
