Clark
One agent. Every financial action.
Clark is being built to plan payroll, investments and cross-border payments, asking for your approval before money moves. It is designed to connect Krypton’s financial tools and give external AI agents access through MCP.
The interface
Two products. One interface.
Clark is designed to bring Krypton Pay and the Yield Engine behind one interface: a single MCP endpoint for agents. The example shows the initialization request and an abridged response.

Clark is the orchestration layer between them: one runtime across both products.
One MCP interface for agents. The example request initializes a session; the response shown is abridged.

Your money, understood
Clark sits across your whole financial life.
Payments, portfolio, yield and tax are one surface to Clark, and it acts on natural language in real time, which is only safe because every action it takes is bounded by a mandate you wrote and, where it moves money, gated by an approval you give.
Understands
Payment patterns, portfolio composition, risk tolerance, tax constraints and jurisdictional limits.

Capabilities
What Clark does once it is connected.
Four behaviours the runtime brings to every request it is handed, whether that request came from you, from a schedule, or from another agent over MCP.
Illustrative product preview
Understands full financial context
Payment patterns, portfolio composition, risk tolerance, tax constraints, jurisdictional limits. Clark supports the complete picture.
Illustrative product preview
Acts across the app, with your approval
Proposes rebalances, routes surplus cash toward the Yield Engine and schedules cross-border payouts. Anything that moves money waits for your approval.
Illustrative product preview
Open runtime via streamable MCP
External AI agents connect to Clark's full financial runtime. Every capability (Pay, Yield, Tax, Strategy) becomes an API for commerce.
Illustrative product preview
Agent marketplace (planned)
On the roadmap: developers will be able to deploy custom financial agents and earn per call, a share of AUM or a share of yield.
How it works
Six moments. One thread.
The app, drawn rather than filmed: a request chosen out of what Clark can actually run, answered with its working attached, and then a payment made in the same thread. Pick a moment and it jumps there.
01 / 06 · Understands
One control from the balance
The ask is a sentence
One call, a stack behind it
The answer is a figure set
And the working sits under it
Then the same thread moves money

Clark opens from the wallet, not from a second app. And it opens on what it can actually run: the stack's jobs, one tap away in the bar you ask in, and behind them requests that execute rather than prompts to adapt.
The wallet, with Clark opened from it. The Ask Clark bar with its row of shortcuts, and a Strategy & Backtesting panel opening from the bar's more button onto example requests, one of which is copied.

MCP
AI agent protocol.
Multilingual
Multiple languages supported.
Tool surface
An agent asks. A human approves.
Clark exposes a query tool and an approval tool. The preview below shows the approval flow planned for a payment request: the agent asks, the run stops at an interrupt, and a person decides.
tools/
- 2 tools
- streamable HTTP
- responses as SSE
Interactive preview · approval behaviour planned
01Agent request
krypton_
Routes a natural-language query through the remote Krypton orchestrator, across Pay and the Yield Engine.
Example: prepare a supplier payment
02Human approval
krypton_
Approves or rejects a pending interrupt before the run continues.
stops atkrypton-pay-approval
03Continuation
After approval, the proposed run can continue.

krypton_query routes a natural-language request through Clark, across Pay and the Yield Engine.
Tool / krypton_query
Before the three calls, one file
The endpoint is registered the way any MCP server is. Nothing here is Krypton-specific except the URL and who you say you are.
jsonclaude_desktop_config.json
1{2 "mcpServers": {3 "clark": {4 "type": "http",5 "url": "https://clark.kryptonfund.com/mcp",6 "headers": {7 "X-Username": "krypton",8 "X-User-Id": "7895abe0-d992-488a-a848-e6b5bd0e300f"9 }10 }11 }12}Connecting takes three calls, not one
The endpoint is a streamable HTTP transport, so the handshake has a shape worth stating plainly rather than hiding behind a one-liner that would fail.
- initialize
Returns the server's capabilities and an Mcp-Session-Id response header.
- notifications/
initialized Echo the session id back as a request header. Every later call needs it.
- tools/
list Now the tool surface resolves. Responses stream as SSE, not plain JSON.
And what it resolves to is the two tools above. That is the whole surface.
Built-in financial agents
A registry with attribution built in.
Every agent call is tracked, metered and attributed. The registry is designed around four agents, covering the operations Krypton is being built to run.
- Payments
Krypton Pay
Cross-border settlement and payroll. Called for anything that moves money between currencies.
- Allocation
Yield Agent
Strategy routing across vaults. Called when idle capital has to be placed against a mandate.
- Quant
Backtesting
QuantConnect Lean. Called to run a strategy over historical data before any capital is committed.
- Compliance
Tax Agent
Jurisdiction-aware. Called to check what a proposed action means where the money actually lands.
On the roadmap
Planned, and labelled as planned.
Neither of these has shipped. They are on this page because a roadmap stated openly is worth more than a roadmap implied by silence.
PlannedDeveloper Platform
Developers deploy custom financial agents onto Clark's runtime, earning per call, per unit of AUM, or per unit of yield generated.
- Planned
Agent Marketplace
A registry where third-party agents are discovered, metered and monetised alongside the built-in set.
