MCP server · In development

Your AI agent will soon read every blockchain.

ChainFoundry's MCP server gives AI agents decoded, structured data from 7 architectures and 500+ networks — self-hosted, no API keys. Preview coming soon.

Coming soon — the MCP server is actively in development.

The underlying primitives (chaincodec, chainrpc, chainindex) already ship across 7 architectures. The MCP wrapper is next. Join the waitlist to get early access.

What is MCP?

Model Context Protocol (MCP) is the open standard — created by Anthropic — that lets AI agents connect to external tools and data. ChainFoundry's MCP server makes blockchain data a native capability for any MCP-compatible AI system.

Under the hood it's just our regular SDK — chaincodec, chainrpc, chainindex, and chaincorrelate — exposed as a set of tool calls the agent can reason about. One config, any chain, every framework.

Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "chainfoundry": {
      "command": "chainfoundry-mcp",
      "args": ["--chains", "ethereum,solana,cosmos,sui"]
    }
  }
}

Then in Claude: “Decode the last transfer event on Ethereum transaction 0x…” or “Did this wallet bridge anything to Solana in the last hour?”

One agent, every chain

How a multichain conversation actually flows.

A single agent, reasoning across heterogeneous architectures, with no per-chain API integration work.

Has 0xA1B2…9D moved any funds out of Ethereum in the last 24h, and did they arrive on Solana?

agent → tool

calling get_transaction(chain="ethereum", address="0xA1B2…9D", since="24h")

agent → tool

calling correlate_bridge(source="ethereum", dest="solana", from="0xA1B2…9D")

agent

Yes — one outbound transfer of 480 ETH to Wormhole on Ethereum, matched to a wrapped ETH mint on Solana 9m later. Time delta and amounts check out. Want the full correlation graph?

Under the hood: two MCP tool calls, dispatched in parallel, each decoded against the chain's native encoding (ABI on EVM, Anchor IDL on Solana, Wormhole VAA matching across both).

Tools your agent gets

8 primitives. Every architecture.

Every tool is backed by the same battle-tested primitives used by production ChainFoundry SDKs — so the agent sees one schema, not seven.

MCP tool	What it does	Chain coverage
decode_event	Decode a transaction's events on any chain	EVM, Solana, Cosmos, Substrate, Bitcoin, Aptos, Sui
decode_call	Decode a function / instruction / message call	EVM (ABI), Solana (Anchor), Cosmos (Msg), Sui (Move entry)
get_block	Get block header + tx list from any chain	All 7 architectures, canonical shape
get_balance	Native + fungible token balances at any height	ERC-20, SPL, CW-20, IBC, BRC-20, Move coins
get_transaction	Full tx details with decoded events + errors	Includes Solana logs, Cosmos events, Sui object changes
correlate_bridge	Trace a bridge deposit to its withdrawal on another chain	Wormhole, LayerZero, Circle CCTP, IBC (v2 roadmap)
list_supported_chains	Show all supported chains and architectures	500+ networks today
list_schemas	Browse bundled protocol schemas (CSDL)	Uniswap, Raydium, Osmosis, Lido, Wormhole…

Multichain by construction

The same agent call, translated per chain.

The MCP server normalizes every chain's binary encoding into a single canonical shape — so your agent can reason about a Sui object change the same way it reasons about an ERC-20 Transfer.

Ethereum

decode_event → Uniswap v3 Swap

Solana

decode_event → Raydium swap (Anchor IDL)

Cosmos

decode_call → Osmosis IBC transfer

Polkadot

get_block → SCALE-encoded extrinsics

Bitcoin

get_transaction → UTXO graph + Ordinals inscription

Sui

decode_event → Move object mutation

Aptos

get_balance → Move fungible asset store

How it works

Five hops. Every chain.
