Claim this listing →Overview
Blockchain MCP by Tatum exposes the Tatum Blockchain Data API and RPC Gateway so LLM clients can query blocks, transactions, balances, and token metadata across 130+ networks, spanning EVM chains (Ethereum, Polygon, Arbitrum, Base, Avalanche) and non-EVM networks (Bitcoin, Solana, Cardano, Ripple, and others). Builders drop it in as a data/RPC layer for agents that need direct chain reads without standing up their own infrastructure; requires a free Tatum API key.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.
Install — as documented by the project, not run by us
Runtime: node
npx @tatumio/blockchain-mcp npx @tatumio/blockchain-mcp (stdio; published binaries: blockchain-mcp, blockchain-mcp-server)
You supply: TATUM_API_KEY (free key at dashboard.tatum.io)
claude mcp add satohub-tatum-blockchain-mcp -- npx @tatumio/blockchain-mcp
A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-15, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
