MCP Servers

orbit-api

MCP server for cross-chain bridging, enabling AI agents to find routes, estimate costs, check risks, execute transfers, and track status across blockchains.

README

orbit-api

The control tower of Orbit — REST API, MCP server, and orchestration layer.

orbit-api is the public face of Orbit. It connects frontends, AI agents (via MCP), and third-party integrations to orbit-core (intelligence) and orbit-executor (execution).

What it exposes

REST API

Method	Endpoint	Description
`GET`	`/routes?from=&to=&asset=&amount=`	Find best routes (quick GET)
`POST`	`/quote`	Find and rank routes (full body)
`POST`	`/execute`	Execute a route
`GET`	`/status/:id`	Track a transfer
`GET`	`/health`	Health check

MCP tools (for Claude, Cursor, VSCode)

Tool	Description
`find_best_route`	Discovers and ranks cross-chain routes
`estimate_bridge_cost`	Returns cost breakdown for a transfer
`check_bridge_risk`	Safety and risk score for a route
`execute_transfer`	Initiates a bridge execution
`check_transfer_status`	Live status of an in-flight transfer

Quick start

npm install
cp .env.example .env
npm run dev

API runs on http://localhost:3000.

MCP setup (Claude Desktop / Cursor)

Add to your MCP config:

{
  "mcpServers": {
    "orbit": {
      "command": "node",
      "args": ["path/to/orbit-api/dist/index.js"],
      "env": { "MCP_MODE": "stdio" }
    }
  }
}

Then ask Claude:

"Find the cheapest route to send 500 USDC from Base to Stellar"

Quote example

curl -X POST http://localhost:3000/quote \
  -H 'Content-Type: application/json' \
  -d '{
    "fromChain": "base",
    "toChain":   "stellar",
    "fromAsset": "USDC",
    "toAsset":   "USDC",
    "amount":    "500"
  }'

Environment variables

PORT=3000
MCP_MODE=          # set to "stdio" to run as MCP server
