Use the Explorer MCP server when an agent needs live chain context from the explorer without scraping pages or guessing from stale context.

​
Use This When

  • you want an agent to inspect a block, transaction, account, or program ABI
  • you want to debug deployed behavior against a specific network
  • you want recent chain activity or account transaction history
  • you want a tool-friendly way to search unknown ta..., ts..., or slot values
Choose another interface when:
  • you need to send transactions or mutate chain state: use CLI Reference or the relevant SDK
  • you need a typed application integration: use the REST API, gRPC API, or the appropriate SDK
  • you are still deciding which docs to read: start with Build with LLMs

​
Installation

Use the public Explorer MCP endpoint: 
https://scan.thru.org/api/mcp

​

codex mcp add thruExplorer --url https://scan.thru.org/api/mcp
codex mcp list

What It Exposes

The explorer app hosts an MCP server at /api/mcp and exposes these tools: On the public explorer, the MCP endpoint is: 
https://scan.thru.org/api/mcp
  • get_block
  • get_transaction
  • get_account
  • list_account_transactions
  • list_recent_blocks
  • list_recent_transactions
  • search
  • get_program_abi
Every tool ultimately calls the explorer API with format=toon, which means the returned content is optimized for LLM consumption instead of browser rendering.

​
RPC Override

The MCP endpoint accepts an optional ?rpc=<url> query parameter. Use that when:
  • you are debugging a non-default network
  • you want the same agent workflow against devnet, staging, or another explorer-compatible RPC endpoint
If the rpc value is missing or invalid, the explorer falls back to its default network.
