Hgraph
Live blockchain data across many networks through one endpoint
Overview
What Hgraph does
Hgraph indexes blockchain data and exposes it three ways: GraphQL over enriched indexed data, read-only SQL against full network history, and JSON-RPC calls to live nodes on EVM networks. Coverage includes Hedera alongside Ethereum, Base, Polygon, Optimism, Avalanche and BNB Chain, with a chain listing call so newly added networks appear without reconfiguration. Questions the publisher points at include account balances, portfolio composition, token supply and holders, transaction history, NFT activity, DeFi metrics and network statistics. The listing also states the server supplies each chain's schema conventions up front so a query resolves on the first attempt rather than after several rounds of correction.
Tool surface
Six tools carry three query languages between them, so each has to be broad, but the endpoint refused the listing request outright and the names stay unconfirmed.
Availability
Where Hgraph is listed
Hgraph is listed in the Claude connectors directory only. Hgraph, Inc 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
Hgraph publishes 6 tools to Claude. That is a mid-sized surface: 28.1% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Data & Analytics publishes 12, so this one sits 6 tools below its bucket's median, 142nd of 198.
It falls in the 4-6 tools band, which holds 16.2% of the Claude directory.
Hgraph 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.

Hgraph 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 Hgraph, Inc describes it
Hgraph connects Claude directly to live blockchain data across networks including Ethereum, Base, Optimism, Polygon, Avalanche, BNB Chain, Hedera, and a growing list of others, through a single connector. Ask questions in plain English and get real-time, network-specific answers such as account balances, portfolio breakdowns, token supplies and holders, transaction history, NFT activity, DeFi metrics, and network analytics. Key features: - One connector, every network — a list_chains tool shows what's live; new chains appear automatically, no reconfiguration - GraphQL — rich indexed queries over enriched blockchain data - SQL — direct read-only queries against full network history - JSON-RPC — live node calls on EVM networks - Built-in context — the connector teaches Claude each chain's schemas and conventions, so queries work on the first try. Data is served from Hgraph's own bare-metal infrastructure with real-time updates. Get started free at app.hgraph.com.
