What's New

Repositioned for Claude Code users — BlockRun MCP is now focused on giving your AI agent access to live data, not just more models.

Tools

• blockrun_search — real-time web + news search
• blockrun_exa — neural research via Exa (papers, competitors, similar products)
• blockrun_twitter — X/Twitter intelligence via Grok
• blockrun_markets — prediction markets (Polymarket, Kalshi)
• blockrun_dex — DEX prices via DexScreener (free)
• blockrun_image — image generation (DALL-E 3, Flux)
• blockrun_chat — second opinion from GPT, Gemini, DeepSeek, etc.
• blockrun_wallet — balance, budgets, spending reports
• blockrun_models — list models with pricing

Changes since v0.4.1

• Exa fix: switched from nonexistent llm.exaSearch() to requestWithPaymentRaw, fixed double /api path
• Dex tool: now properly registered
• Chat tool: repositioned as "second opinion", not primary value
• Hosted option: mcp.blockrun.ai/mcp available (HTTP transport)
• Cleaned repo: removed dead tools (whale, analyze, signal, swap), dead constants, internal docs
• Dual chain: supports Base and Solana wallets
