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
