Exposed MCP Tools (4)

safe

read_contract

Reads the state of a smart contract on a specified blockchain network.

Read-only operation, no modification of contract state.

safe

get_proxy

Retrieves the implementation contract address for a given proxy contract.

Read-only operation, no modification of contract state.

safe

get_events

Fetches event logs for a contract based on specified filter criteria.

Read-only operation, retrieves existing event data.

safe

build_event_topic

Generates an event topic signature from an event name and argument types.

Pure computation, no external interaction.

Safety Assessment

The server is relatively safe for read operations on blockchain data. However, the lack of sandboxing and reliance on external APIs introduce some risks. It is crucial to protect the Bankless API token and validate the data retrieved.

Read-only contract state access
Event log retrieval with filtering
No direct modification of blockchain state
API key authentication
Rate limiting to prevent abuse

Potential for data exposure if API key is compromised
Reliance on Bankless API security
Risk of incorrect data interpretation by AI models
No sandboxing of contract interactions
Vulnerable to supply chain attacks via npm dependencies
