Bankless Onchain
MCP server that provides access to blockchain data and smart contract interactions via the Bankless Onchain API. Enables AI agents to read contract state, retrieve contract source code and ABIs, query event logs, and fetch transaction history across multiple EVM networks.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API token passed via environment variable, not hardcoded. Dependencies use standard MCP SDK and JSON schema tools. No CVE data available for analysis. Scope is all-or-nothing: single API token grants access to all Bankless API capabilities without granular permission control. MCP server itself is read-only (no state mutation), reducing risk surface.
⚡ Reliability
Best When
You need an AI agent to programmatically analyze smart contracts, look up on-chain data, and understand contract behavior without manual API calls.
Avoid When
You need transaction writing capabilities, complex real-time data subscriptions, or support for non-EVM networks.
Use Cases
- • Smart contract analysis and verification
- • Blockchain data retrieval for AI agents
- • Event log searching and decoding
- • Transaction history lookup
- • Proxy contract implementation resolution
- • ABI and source code fetching for verified contracts
Not For
- • Writing smart contracts or performing transactions
- • Real-time blockchain state monitoring at scale
- • Building public-facing blockchain explorers
- • Non-EVM blockchain ecosystems
Interface
Authentication
Single API token via BANKLESS_API_TOKEN environment variable. No granular scopes or OAuth. Token is passed to Bankless API backend.
Pricing
MCP server itself is open source. Costs depend on Bankless API backend usage.
Agent Metadata
Known Gotchas
- ⚠ Error recovery strategy not documented — agents should implement exponential backoff for rate limits
- ⚠ Proxy contract handling requires multi-step logic (get_proxy → follow implementation), adding complexity to agent workflows
- ⚠ Rate limit handling relies on Bankless API backend; no client-side rate limit headers mentioned
- ⚠ Event topic building requires correct ABI understanding; mismatch between event signature and arguments will silently fail
