The SQD plugin connects Claude Code to blockchain data across 140+ networks through the hosted Portal MCP server. Coverage includes Ethereum, Base, Solana, Polkadot, Bitcoin, Tron, Hyperliquid, and many more networks. The package adds 28 read-only MCP tools plus four skills for Portal, Pipes SDK, and Squid SDK projects.
Before you start: install Claude Code. Run the install commands below in your terminal, not inside the Claude Code chat.
Using Claude on the web, desktop, or mobile instead? Add SQD from the Claude Directory. The connector gives Claude the hosted MCP tools. The Claude Code plugin also includes the four coding skills.

​
Install

1

Add the SQD plugin marketplace

A marketplace is a catalog of plugins. This command registers SQD’s catalog so the next step can install from it.
2

Install the Portal plugin

3

Restart Claude Code

Claude Code loads plugin MCP servers when a session starts. Exit Claude Code (/exit) and start it again with claude.
4

Confirm it loaded

In the new session, run the /mcp command inside Claude Code. The SQD server should be listed as connected.

What gets added

​
Try it

Start with a direct request:
  • “Which blockchain networks can SQD query?”
  • “Show me up to 200 BTC perp fills on Hyperliquid from the past hour.”
  • “How many transactions landed on Base in the past 2h?”
  • “Track USDT transfers on Tron.”
  • “Migrate this Squid SDK project from the v2 gateway to Portal.”
  • “Build a Pipes SDK indexer for USDC transfers on Ethereum.”
For a bounded data question, Claude Code should call a portal_ tool and return query results. The bundled Portal skill handles raw exports, including data shapes not exposed as a dedicated MCP tool. The other skills help build Pipes SDK indexers, migrate Squid SDK projects, and compare Squid sync performance. If Claude Code only explains how to fetch the data, restart Claude Code and check /mcp.

​
Troubleshooting

  • portal@sqd not found: confirm the marketplace add command finished without errors, then rerun claude plugin install portal@sqd.
  • Plugin installed but no tools: restart Claude Code so it loads the plugin’s MCP server, then run /mcp to confirm SQD is connected.
  • Prefer manual setup: configure the endpoint by hand from the Portal MCP Server page instead.
