Overview

What SQD does

SQD Portal indexes onchain data across a large number of networks, and this hosted server exposes it read-only. Networks can be discovered, tokens and contracts resolved into query-ready identifiers, and then wallets, transactions, logs, token transfers and chain-level analytics queried without writing raw API calls. Results come back structured enough to turn straight into tables or charts. Published by Subsquid Labs, twenty-eight tools claimed, and the endpoint answered a tool listing without credentials, which matches its description as read-only.

Who it is for

Onchain analysts and researchers working across several chains at once.

Tool surface

The twenty-eight tools are namespaced by virtual machine: portal_evm_*, portal_solana_*, portal_bitcoin_*, portal_substrate_* and portal_hyperliquid_*, sitting beneath shared helpers like portal_resolve_entity, portal_get_wallet_summary and portal_get_time_series. Every name is a query or a get, with three portal_debug_* tools held back for raw block and timestamp work.

Availability

Where SQD is listed

SQD is listed in the Claude connectors directory only. Subsquid Labs GmbH has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.

Claude listing

In the Claude connectors directory

SQD publishes 28 tools to Claude, deeper than 79.2% of the 1,253 Claude-listed connectors.

The median Claude-listed connector filed under Data & Analytics publishes 12, so this one runs 16 tools above its bucket's median and ranks 29th of 198 by tool count.

It falls in the 21-50 tools band, which holds 20% of the Claude directory.

Measured against the live endpoint

A direct call to the endpoint returned 28 tools, matching the 28 the listing publishes. Probed 2026-08-07.

SQD publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.

Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

SQD is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.

In the publisher's words

How Subsquid Labs GmbH describes it

SQD Portal lets Claude query indexed blockchain data through a hosted, read-only MCP server. It validates user intent, maps requests to Portal API queries, and returns structured results that are easy for Claude to inspect, summarize, and turn into tables or charts. Users can discover supported networks, resolve tokens and contracts, inspect wallets, query transactions, logs, token transfers, Hyperliquid fills, Bitcoin activity, Solana instructions, and chain-level analytics without writing raw API calls.
