Zerion Hosted MCP

Use Zerion's hosted MCP as the primary interface for MCP-native agent environments.

Endpoint

https://developers.zerion.io/mcp

When to use

Use the hosted MCP when your client supports MCP and the model should choose and call tools directly (Cursor, Claude, etc.).

Use the CLI when your environment expects shell commands returning JSON. See cli/README.md.

Authentication

See the root README for full auth setup (API key or x402 pay-per-call).

Supported clients

• Cursor: examples/cursor

• Claude: examples/claude

Wallet-analysis walkthrough

Use one of the example wallets:

• vitalik.eth / 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

Then ask:

Analyze this wallet and summarize:
- total portfolio value
- top holdings
- DeFi positions
- recent transactions
- PnL

The tool catalog in mcp/tools/ documents the concrete wallet capabilities.

Failure modes

• Missing or invalid API key

• Invalid address or ENS resolution failure

• Unsupported chain filters

• Rate limits (429)

• Upstream timeout or temporary unavailability

• Empty or partially bootstrapped wallet state
