Safe MCP Server

An MCP (Model Context Protocol) server implementation for interacting with Safe (formerly Gnosis Safe) smart contract wallets.

Features

  • Query Safe transactions for any Safe address
  • Get multisig transaction details
  • Decode transaction data
  • Safe API integration

Installation

npm install

Usage

npm run build
npm start

No configuration is required - the server uses the Safe Transaction API mainnet endpoint by default.

Available Tools

getSafeTransactions

Get all transactions for any Safe address. The Safe address is determined by the LLM at runtime based on the context of the conversation.

// Example tool call
getSafeTransactions({
  address: "0x123...", // Safe address determined by LLM
  limit: 100, // optional
  offset: 0, // optional
});

getMultisigTransaction

Get details of a specific multisig transaction.

getMultisigTransaction({
  safeTxHash: "0x456...", // Transaction hash to query
});

decodeTransactionData

Decode transaction data using Safe API.

decodeTransactionData({
  data: "0x789...", // Transaction data to decode
  to: "0xabc...", // Optional contract address
});

Configuration (Optional)

By default, the server uses the Safe Transaction API mainnet endpoint:

https://safe-transaction-mainnet.safe.global/api/v1

If you need to use a different endpoint (e.g., for testnet), you can set it via environment variable:

SAFE_API_URL=https://safe-transaction-goerli.safe.global/api/v1 npm start

Development

npm run dev

Runtime guide

cloud

Hosted runtime

Hosted servers run from a provider-managed environment. You usually connect the MCP client to the hosted endpoint or follow the provider's authorization flow, without keeping a local process alive

  1. Open provider connection page
  2. Authorize or copy endpoint
  3. Connect from your MCP client
terminal

Local runtime / other methods

Local servers run on your own machine or infrastructure. You normally copy the server_config into your MCP client, install the required package, and provide env variables from env_schema when needed

  1. Copy server_config
  2. Install required package
  3. Fill env variables and restart client
