Marsbit Opennews

MarsBit OpenNews Skill (Directly Usable)

This skill is designed to work immediately after installation using the hosted MCP endpoint.

MCP endpoint:

• https://www.marsbit.co/api/mcp

Use this endpoint in all commands:

MCP_URL="https://www.marsbit.co/api/mcp"

Runtime rules

When user asks for MarsBit news/flash info, call MCP tools via curl directly.

Required headers for every MCP POST:

• Content-Type: application/json
• Accept: application/json, text/event-stream
• mcp-protocol-version: 2025-11-25

Response parsing:

• MCP wraps tool output in result.content[0].text
• text is a JSON string; parse it before answering
• If success is false, surface the error and ask user whether to retry with different params

Backend architecture alignment

This skill relies on the current marsbit-co hosted MCP implementation (/api/mcp), which internally uses:

• fetcher(..., { marsBit: true }) in src/lib/utils.ts
• News APIs: /info/news/channels, /info/news/shownews, /info/news/getbyid, /info/news/v2/relatednews
• Flash API: /info/lives/showlives
• Search API: /info/assist/querySimilarityInfo (via src/lib/db-marsbit/agent)
