solana_contract_dataGet Solana token details by contract address.
| Action | Description |
|---|---|
get-token-details-by-contract-address | Get token details by contract address |
Supported Networks: mainnet, devnet
| Argument | Description | Default |
|---|---|---|
--api-key | Crypto APIs API key | CRYPTOAPIS_API_KEY env var |
--transport | Transport type: stdio or http | stdio |
--host | HTTP host | 0.0.0.0 |
--port | HTTP port | 3000 |
--path | HTTP path | /mcp |
--stateless | Enable stateless HTTP mode | false |
When using HTTP transport, the server supports two API key modes:
--api-key: The key is used for all requests. x-api-key request headers are ignored.--api-key: Each request must include an x-api-key header with a valid Crypto APIs key. This enables hosting a public server where each user provides their own key.# Per-request key mode (multi-tenant)
npx @cryptoapis-io/mcp-contracts --transport http --port 3000
# Clients send x-api-key header with each request
Stdio transport always requires an API key at startup.
Warning: Making requests without a valid API key — or with an incorrect one — may result in your IP being banned from the Crypto APIs ecosystem. Always ensure a valid API key is configured before starting any server.
Crypto APIs provides an official remote MCP server with all tools available via HTTP Streamable transport at https://ai.cryptoapis.io/mcp. Pass your API key via the x-api-key header — no installation required.
