Strategy & architecture
Define the commercial and customer journeys, participant roles, target markets and integration boundaries. Inventory the estate and prioritize interfaces by value, risk and readiness.
Open Banking, API Ecosystems & Agentic AI
Connect customers, financial institutions and approved partners through purposeful APIs. Make banking information useful across channels while retaining clear consent, ownership and operating boundaries.
Select a stage to explore its purpose and controls.
Give customers a clear view of what information is shared, with whom and for what purpose. Design the permission journey alongside the API.

A Genellipse integration pattern for Cortex AI OS and MCP. Agents receive a bounded toolset; bank APIs retain their authorization and consent checks. The model does not become the authority to move money.

How Genellipse helpsMap the workflow, build adapters and bounded tools, evaluate agent behavior, and establish monitoring, escalation and operating ownership.
OPEN BANKING WITH AN OPERATING MODEL
Banking transformation spans customer experience, established systems, partner relationships and the responsibilities of a regulated institution. Genellipse brings process design, engineering, data, AI and security together around a practical implementation.
We help define what should be exposed, who may use it, how it should behave and who owns the result. Start with a valuable journey, validate its controls and expand with evidence.
Define the commercial and customer journeys, participant roles, target markets and integration boundaries. Inventory the estate and prioritize interfaces by value, risk and readiness.
Design OpenAPI contracts, resource models, pagination, versioning and predictable errors. Implement gateway policies, contract testing, safe retries and idempotency for relevant state-changing operations.
Connect supported core interfaces, adapters, files and events. Account for batch cut-offs, stale data, dependencies and vendor limits. Reconcile parallel runs before retiring an existing path.
Build purpose-specific authorization journeys, permission dashboards and revocation handling. Define partner registration, sandbox testing and approval gates appropriate to the target ecosystem.
Package approved API operations as narrow tools. Define agents, solution packs and applications around specific tasks, with evaluations, permission boundaries, human approvals and operational ownership.
Threat-model the full journey, test access boundaries and recovery, and configure monitoring. Deliver key and certificate lifecycle procedures, incident runbooks, support responsibilities and release controls.
EIGHT PRACTICAL BANKING JOURNEYS
Explore illustrative workflows, the controls they need and the measures that make progress visible. These examples describe potential engagement scopes.
Account servicing
Service teams navigate multiple screens to explain transactions, fees or account status.
An approved assistant retrieves permitted account and transaction data, prepares a source-linked explanation and routes disputed or incomplete information to the right team.
Identity and record-level access are checked before retrieval. The assistant cannot change account entitlements or move money.
Handling time, first-contact resolution, correction rate and unauthorized-access test results.
SECURITY IS PART OF THE DESIGN
Genellipse works with your security, risk and engineering teams to turn controls into implementation requirements, test evidence and operating procedures.
Distinguish customer consent, client authentication, user authority and account-level access. Apply the required OAuth and financial-grade profile, including sender-constrained tokens where the profile requires them.
Minimize payloads and model context. Design encryption, secret handling, key rotation, masking, residency and retention around the bank’s data classification and approved providers.
Allowlist tools and destinations, validate schemas and keep credentials outside prompts. Treat documents and tool responses as untrusted. Test prompt injection, data leakage and attempts to bypass approval.
Keep transaction authorization outside the model. Enforce limits, separation of duties and customer confirmation where required. Handle idempotency, replay, status uncertainty and reconciliation explicitly.
Use timeouts, circuit breakers and bounded retries appropriate to the operation. Make stale or incomplete data visible. Test dependency outages, recovery, revocation and operational fallback.
Correlate the initiating identity, consent reference, API calls, agent version, source evidence, approvals and outcome. Redact sensitive logs and apply access and retention controls.
UK Open Banking’s published security profile and the OpenID Foundation’s FAPI 2.0 specification are distinct implementation references. Confirm the required profile, version and conformance process for each market. MCP authorization complements these boundaries; it does not replace banking consent or payment authorization.

Explore productPARTNERSHIP THROUGH IMPLEMENTATION
Agree one workflow, selected interfaces and clear acceptance criteria. The schedule begins when access, test environments and critical dependencies are ready. Wider rollout follows a separate plan.
Weeks 1–2: confirm the journey, legal and operating context, interfaces, consent design, baseline and acceptance criteria.
Approved scope and readinessWeeks 2–4: implement the selected APIs and adapters, connect permitted tools and configure workflow permissions in a representative environment.
Contract and integration testsWeeks 3–5: exercise normal paths, expired consent, duplicate requests, model errors, failed dependencies and recovery.
Business and security acceptanceWeeks 5–6: complete the agreed MVP release, monitoring, runbooks and training. Wider rollout follows the bank’s approval and change process.
Named owners and rollout decisionYour bank nominates business, engineering, risk and security owners; provides permitted test access and representative data; and approves acceptance and change decisions. Genellipse coordinates delivery with named responsibilities and regular evidence-based reviews.
External approvals, unsupported connectors and broader core migrations are planned explicitly. A full Open Banking program can extend beyond the first MVP.
MAKE THE BUSINESS CASE TESTABLE
This illustrative capacity model uses your assumptions. It is not a Genellipse performance claim, price quote or guaranteed saving.
ILLUSTRATIVE ANNUAL OPPORTUNITY
220,000Net capacity value, in your currencyCapacity value is not automatically cash saved. Include integration, licensing, model usage, review, change management and support in the cost assumption. Confirm whether released time can be redeployed or expenditure avoided.
Calculation: monthly cases × minutes reduced ÷ 60 × hourly cost × 12, less annualized implementation and running cost. Negative time reductions are treated as zero capacity released.
COMMON QUESTIONS
Explore the scope, practical considerations, and a useful starting point for your team.
Not necessarily. We first assess supported interfaces, batch processes, vendor permissions and operational constraints. A phased API layer can extend a viable core; replacement is considered where controls, economics or technical limits make extension unsuitable.
Open Banking concerns permissioned banking data and services within a defined ecosystem. OpenAPI describes HTTP API contracts. MCP lets compatible AI applications discover and use exposed tools and resources. They can work together, but none substitutes for the bank’s authorization and transaction controls.
Yes, the design can evaluate existing models and compatible agents alongside Cortex AI OS. Confirm tool support, identity propagation, data handling, deployment constraints and evaluation evidence before approving an integration. An OpenAI model is one possible provider choice, not a requirement for Open Banking.
Only within an explicitly approved architecture and participant role. Separate recommendation from execution. Any money-moving capability needs the applicable customer and bank authorization, transaction limits, access controls and reconciliation. The initial MVP can remain read-only.
No. MCP needs a secure implementation, narrowly scoped tools and validated authorization. Banking APIs must independently enforce their own permissions. Do not pass an incoming MCP access token unchanged to a downstream banking API; use the appropriate downstream authorization flow.
Discovery identifies the target market, participant role and applicable API, security and customer-experience requirements. UK Open Banking, European frameworks and other market ecosystems differ. We agree the relevant profiles, versions and conformance work rather than assuming one implementation qualifies everywhere.
A focused MVP for one agreed journey, such as a read-only servicing assistant or a reconciliation investigation flow, with selected interfaces, validation evidence and an operating handover. Access, test environments, owners and dependencies must be ready. A full banking transformation or external authorization can require a longer program.
Establish a baseline for the chosen workflow, then compare handling time, exceptions, quality and total operating cost. Include implementation, integration, licensing, model usage, human review and support. Publish measured results only after the bank approves the evidence.
