rpc

Start here. Pay-per-call access to AI models, real-time data, media generation and multi-chain RPC over x402 — which tool to reach for, how the wallet works, and how to get a first call working without spending anything.

Use when BlockRun MCP is installed but misbehaving — Failed to connect, spawn npx ENOENT, HTTP 402, fetch failed, media timeouts, missing spend dialogs, or a Polymarket order failing after funding. Symptom → cause → fix, plus what never to do.

1 skill

Use when asked to install, add, or set up the BlockRun MCP server in Claude Code, Cursor, Codex or another client — the nvm/Homebrew PATH fix, first-run wallet, funding with USDC, profiles, and proving the install works.

1 skill

Use when the server prints 'Update available', when asked to upgrade, pin or roll back @blockrun/mcp, when a fix should be in the new version but the client still runs the old one, or when refreshing skills copied into a project.

1 skill

Use for any crypto data question — token prices, FX, commodities, stock ticker catalog, OHLC history, DEX pairs, DeFi TVL and yields, on-chain SQL, wallet labels and net worth, social mindshare. Routes across five overlapping tools and says which one to use and which are free.

1 skill

Use when the user wants typed judgments over their own data — yes/no probabilities, a labelled choice, or a rubric score over text or images. BlockRun Decisions (OpenAI Decisions-compatible, gpt-6-luna): served only at api.blockrun.ai/v1/decisions, free with a key (no x402 rail). Not an MCP tool; called with curl.
