MCP server · Unto Labs

thru-explorer

Official hosted MCP server on the Thru block explorer. Lets AI agents inspect blocks, transactions, accounts, recent activity, search results, and on-chain program ABIs with live chain context. Tool responses use an LLM-oriented text format (format=toon) instead of browser HTML.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "unto-labs": { "url": "https://scan.thru.org/api/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "unto-labs": { "command": "npx", "args": ["-y", "mcp-remote", "https://scan.thru.org/api/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://scan.thru.org/api/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools

get_block — Inspect a specific block, its producer, timestamps, and transaction rows.
get_transaction — Debug a single transaction, including accounts, instructions, and events.
get_account — Look up account metadata, balance, owner, and flags.
list_account_transactions — Walk an account's recent history without fetching each transaction manually.
list_recent_blocks — Recent network activity and slot-level monitoring (limit 1-50).
list_recent_transactions — Recent chain-wide transaction activity (limit 1-50).
search — Resolve whether an unknown value is a slot, transaction signature, or account address.
get_program_abi — Fetch the on-chain ABI that explorer tooling uses for reflection.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
