Cyclr: Turn Your API into MCP Servers for the AI Economy
Every B2B SaaS team eventually hits the same wall. Customers want their tools to talk to each other — the customer relationship management (CRM) system, the enterprise resource planning (ERP) platform, the marketing automation tool, the niche regional database nobody outside their industry has heard of. So engineering builds the first integration. Then the second. Then the tenth. Then a customer asks for an integration with an on-premises system written over a decade ago, and someone realizes that maintaining bespoke API wrappers is no longer a sustainable engineering strategy.
Layer the artificial intelligence (AI) conversation on top, and the math gets worse. Product teams are now expected to expose their APIs to agents, support Model Context Protocol (MCP) servers, gatekeep authentication for autonomous workflows, and orchestrate data between large language models and the rest of the stack. Building all of that in-house is possible. It’s also a fast way to spend the next two years rebuilding plumbing instead of shipping product.
Cyclr
Cyclr is an embedded integration platform as a service (iPaaS) built for B2B Software-as-a-Service (SaaS) companies that want to ship native integrations and expose their APIs to AI agents without rebuilding integration infrastructure from scratch.
Cyclr sits within your product as a multi-tenanted layer, meaning each of your customers gets a ring-fenced account with its own credentials and data flow. Engineering keeps the surface area small while customers get the connectivity they expect. Cyclr’s visual, low-code builder handles authorization, paging, API rate limits, and extract-transform-load (ETL) data transformation across more than 600 connectors, so a product manager can ship a new integration template without filing engineering tickets for every API quirk. For teams moving into agentic territory, the same infrastructure exposes APIs as user-generated MCP servers with security and tenancy handled at the platform level.
What’s Inside Cyclr
Cyclr’s capabilities span the full integration lifecycle, from initial connector configuration through long-term operational management.
- AI Orchestration: Coordinate data flows between AI models, agents, and the rest of your SaaS stack, with multi-tenancy acting as the gatekeeper for AI access at scale.
- API Connector Ecosystem: Over 600 prebuilt connectors covering SaaS applications, APIs, and data sources, each handling authorization, paging, rate limits, and ETL transformation.
- Authentication Gatekeeping: Multi-tenanted controls that keep customer credentials isolated and govern which agents and users can call which endpoints.
- Data on Demand API: A single unified API for pulling third-party (3P) data into your product without standing up individual integrations for each source.
- Integration Delivery: Embeddable user interface components and an API for building in-app integration experiences that your customers can configure themselves.
- Integration Management: Monitoring, logging, and operational tooling for keeping live integrations healthy across your customer base.
- MCP Platform as a Service (PaaS): Convert your existing API into user-generated MCP servers with security, authentication, and tenancy handled for you.
- On-Prem Integrations: Connect to proprietary on-premises systems, local ERPs, and databases that sit behind a customer’s firewall.
- Orchestration Layer: Low-code visual tooling for designing the logic, mapping, and conditional flows that move data between systems.
- Private Deployments: Run Cyclr in your own hosted environment to meet enterprise security, regulatory, or data residency requirements.
A lot of the systems we need to integrate with are niche and so specific, local ERP systems for instance. It would mean I’d need 10 people to maintain these and change their APIs, which is a bit of a headache financially. That’s why it makes sense to implement Cyclr; it takes the burden away and allows us to only create native integrations to our core code that add value to our product.

Taken together, Cyclr’s connector ecosystem, orchestration layer, MCP capabilities, and deployment options provide B2B SaaS and service providers with a single platform for handling everything from Salesforce syncs to agent-driven workflows. The result is less engineering capacity tied up in integration plumbing and more available for the product work that actually differentiates your offering.

Frequently Asked Questions
What’s the difference between an embedded iPaaS and a traditional iPaaS like Zapier or Workato?
A traditional iPaaS is a standalone product that end users log into to build their own automations. An embedded iPaaS like Cyclr lives inside your SaaS product, so your customers experience integrations as native features rather than third-party connections. This keeps the user experience consistent and gives your team control over which integrations are exposed.
How does MCP PaaS differ from building your own MCP server?
Building your own MCP server means handling authentication, multi-tenancy, rate limiting, and version management on top of the actual API logic. Cyclr’s MCP PaaS abstracts that infrastructure so you can expose your existing API to agents quickly, with security and tenant isolation already built in. It’s the difference between writing a server from scratch and configuring one.
Can Cyclr connect to on-premises systems behind a firewall?
Yes. Cyclr supports on-prem integrations for proprietary systems, local ERPs, and databases that don’t expose public APIs. Combined with private deployment options, this lets B2B service providers connect customer data sources that wouldn’t typically be reachable from a public-cloud iPaaS.
