deBridge: DLN API, widget, MCP, and agent skills

deBridge is cross-chain liquidity and execution. The builder door is debridge.com/develop. Docs live at docs.debridge.com. Index: docs.debridge.com/llms.txt.

DLN (deBridge Liquidity Network) is a 0-TVL swap layer. Solvers fill intents instead of AMM pools. Same-chain and cross-chain. Hooks run extra calls on fill. DMP is the messaging layer. dePort lock-and-mints a token onto secondary chains. IaaS connects a new chain to the network.

Integration paths

DLN API

Swap API base: https://dln.debridge.finance/. Order tracking: https://dln-api.debridge.finance/. Public access is 50 requests per minute with no key. Authenticated is 300. Limits are per endpoint, not shared. 429 needs backoff. Commercial keys: authentication form.

Docs put trade size from 1 USD to 5.5m USD. Typical fill under 2 minutes. Users can cancel and reclaim. Integrator examples (EVM and Solana) live in api-integrator-example. Review that code before sending real funds.

MCP and agent skills

Hosted MCP: https://agents.debridge.com/mcp. Local: npx -y @debridge-finance/debridge-mcp@latest. Skills: npx skills add debridge-finance/debridge-skills. Agent index: debridge.com/llms.txt. No API key. Same 50 rpm public cap. The MCP package is a stateless proxy onto the REST API.

{
  "mcpServers": {
    "debridge-mcp": {
      "command": "npx",
      "args": ["-y", "@debridge-finance/debridge-mcp@latest"]
    }
  }
}

First tool to call: get_instructions. Then search_tokens. Claude Desktop wants HTTP transport on http://localhost:3000/mcp.

Solana

Solana is in the DLN examples (Polygon USDC ↔ Solana USDC) and in the agent MCP copy (20+ EVM chains and Solana). For a Solana → Hyperliquid hop, keep the older piece: Solana to Hyperliquid programmatic bridges.
