Integration

Overledger integration

Overledger is Quant's multi-blockchain gateway, here its Fusion Rollup server (the public testnet endpoint the vendor publishes). An agent can read the networks it reaches, its own identity, transactions, deposits, swaps, withdrawals and stakes, read deployed Fusion contracts and grant or revoke access to permissioned ones, register or remove its own RPC nodes and provider reset policies, track a transaction hash or watch an address or contract event with an HTTPS callback, get swap quotes, and drive Flow Apps (start a session, read and submit steps, run read-only queries, subscribe to app webhooks). Deposit, swap, stake and withdrawal routes only RECORD transactions the user already signed and sent on chain; they move no funds. Submitting a Flow App step CAN move funds: a payment-gated step settles a token payment on chain, and a transaction step is signed and broadcast by Quant when Quant holds the account's keys. Not included: the health checks, the raw JSON-RPC proxy (its URL carries the key) and API key administration. Authentication is an Overledger API key (fk_<keyId>.<secret>) created in Quant Connect (API Keys page), sent in the X-API-Key header.

Connect Overledger How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Overledger.Built from the 63 Overledger tools below, on the connection you add once.

What you can do with Overledger

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Status, 4 operations

get_tracked_transactionGet tracked transactionGETReturns the current status of a transaction tracked with track_transaction.
refresh_deposit_statusRefresh deposit statusGETRefreshes a deposit's on-chain status and returns it (status, transaction hash, last check time, failure reason).
refresh_swap_statusRefresh swap statusGETRefreshes a swap's on-chain status and returns it (status, transaction hash, actual output, failure reason).

Use Overledger from Claude Code, Cursor or Codex

Connect Overledger in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Overledger operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs
