MarsBit Crypto News Skill (Web3-focused)

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"

Capabilities

Use this skill when users ask about:

1. Crypto market-moving headlines
2. Web3 ecosystem updates (Ethereum, Solana, Base, Arbitrum, etc.)
3. DeFi protocols, CeFi exchanges, ETFs, policy and regulation
4. Flash updates for short-term market sentiment
5. Narrative discovery (RWA, AI x Crypto, DePIN, restaking, meme sectors)

Runtime rules

When user asks for crypto/Web3 information, 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

Web3 answer format recommendation:

1. TL;DR (1-2 lines)
2. Market impact (bullish / bearish / neutral + why)
3. Key entities (token/protocol/chain/exchange/regulator)
4. Sources with publication time

Intent -> tool routing (Web3)

1. Latest crypto headlines -> get_latest_news
2. Category/channel browsing -> get_news_channels
3. Narrative or keyword lookup -> search_news
4. Deep dive one article -> get_news_detail
5. Context expansion -> get_related_news
6. Short-term market pulse -> get_latest_flash
7. Event scanning by keyword -> search_flash

Useful query patterns:

1. Chain: Ethereum, Solana, Base, Arbitrum, Sui
2. Protocol: Uniswap, Aave, Jupiter, Pendle
3. Narrative: RWA, DePIN, restaking, AI crypto
4. Risk/Event: hack, exploit, liquidation, SEC, ETF

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)
