Beyond ContextForge: Modern Alternatives for MCP Workflows
Introduction
The Model Context Protocol (MCP) has rapidly become a key standard for integrating AI agents with tools and data sources . ContextForge is one of the flagship tools in this space — an open-source MCP Gateway originally developed with IBM’s involvement. ContextForge serves as a gateway, proxy, and registry that federates multiple MCP servers and even traditional REST APIs into one unified endpoint . In essence, it acts as a central hub in front of your AI tools and services, handling discovery, authentication, rate-limiting, and more, so that AI clients (like LLM-based agents) can access a wide catalog of capabilities through a single interface. To developers, this sounds powerful — essentially a “one-stop shop” for MCP-based AI orchestration. But as many early adopters have learned, power comes with trade-offs.
ContextForge packs in enterprise-grade features: it supports federation (multiple gateway instances auto-discover and merge their tool registries), can virtualize legacy APIs by wrapping them as MCP-compatible tools, and speaks multiple transport protocols (HTTP, WebSocket, JSON-RPC, etc.) to accommodate diverse backends . It even offers an optional web Admin UI for live management and extensive observability hooks (OpenTelemetry tracing, metrics on token usage, etc.) for debugging . In theory, it provides everything and the kitchen sink — a private “Zapier for AI” that you can fully control . However, this breadth also makes ContextForge complex. The official documentation itself cautions that ContextForge is an open-source component with no official IBM support, not a fully productized solution . Early versions (pre-1.0) have been beta-quality, with breaking changes and rough edges still being worked out . Industry evaluations note that ContextForge is “very complex to deploy and manage,” recommending it only for teams with significant DevOps expertise . In practice, setting up ContextForge can feel like deploying a whole new piece of infrastructure — requiring databases, caches, and careful configuration — rather than simply adding a library . For smaller developer teams or faster iterations, this overhead and fragility have proven challenging. This gap has led many developers to seek leaner, more accessible alternatives for MCP workflows.
Below, we explore two notable alternatives to ContextForge — Klavis and Peta — and how they stack up. Each takes a different approach to simplifying MCP tool integration. Klavis offers a cloud-based, ready-to-use service with a rich feature set, whereas Peta is a newer self-hosted project built with security and minimalism in mind. We’ll examine what each brings to the table and why an enterprise developer might favor one over the other.
Klavis: Cloud-Powered Convenience with Caveats
What is Klavis? Klavis is a relatively new platform (Y Combinator-backed, founded 2025) that aims to make MCP integrations turnkey for developers . It provides an open-source infrastructure platform coupled with managed cloud services to simplify using, building, and scaling MCP-based tools . In practical terms, Klavis offers hosted MCP servers on dedicated cloud infrastructure, so you don’t have to run your own MCP server instances . These managed servers handle all the heavy lifting — maintaining tool endpoints, managing authentication, and ensuring stable performance — so developers can plug in new AI capabilities without worrying about backend ops . By offering this managed infrastructure, Klavis eliminates the need for teams to deploy or authenticate to their own MCP servers, which lowers the barrier to entry .
Klavis’s feature set is rich and developer-friendly. Out of the box, it supports secure access control via OAuth and user-based authentication, meaning tools and data can be exposed to AI agents in a controlled, permissioned way without embedding credentials in client code . The platform also provides ready-made MCP clients for common environments like Slack, Discord, and web dashboards . This lets users interact with MCP-enabled AI tools directly from chat platforms or a browser, which can greatly streamline workflows. Additionally, Klavis exposes a standardized RESTful API for integrating its MCP services into your own applications or pipelines . In short, the service wraps a lot of the MCP ecosystem (servers, clients, auth, APIs) into one cohesive cloud offering. For a developer, this means you can get started quickly: register your tools or use existing ones, and let Klavis handle the hosting and scaling.
Why not just use Klavis then? The flip side of Klavis’s convenience is its cloud-centric model. Relying on Klavis means your MCP tool calls and possibly sensitive credentials are flowing through a third-party cloud service. This may be fine for hobby projects or less sensitive applications, but many enterprises will think twice. Large organizations often have strict requirements around data residency, security, and compliance — they may be unable or unwilling to trust an external cloud platform to mediate AI tool access. While Klavis does offer enterprise-tier plans (with presumably stronger isolation or even on-prem options), its core proposition is a managed cloud infrastructure. That inherently introduces potential lock-in and less control compared to a self-hosted solution. If your company has policies against putting certain data or connectors in the cloud, Klavis could be a non-starter despite its technical merits. In summary, Klavis shines in ease-of-use — it’s like an “MCP-as-a-Service” that you can subscribe to — but teams must consider the trade-off of cloud reliance. The rich feature set comes at the cost of handing over some control to a vendor’s environment. For startups or smaller teams, that trade-off might be worth it to avoid DevOps overhead. For enterprises with strict security mandates, it may be “too cloud-dependent” to adopt widely (even if parts of Klavis are open source). It’s a fantastic quick solution, but one that raises questions for those who need absolute autonomy over their AI tool stack.

(To be clear, Klavis is actively working on enterprise features — such as role-based access controls and even hints of on-premise deployments in documentation — underscoring that larger customers demand those. But the default use of Klavis assumes comfort with a cloud-managed context.)
Peta: Security-First, Lightweight MCP Gateway
If Klavis is the convenient cloud hub, Peta represents the opposite philosophy: a lean, self-hosted MCP gateway with security built from the ground up. Peta (launched in 2025) is often described as “1Password for AI agents” due to its focus on secrets management and policy enforcement . Where ContextForge tries to cover every imaginable feature and Klavis offers a full cloud stack, Peta zeroes in on the essentials that teams consistently need once AI agents go beyond toy examples . The creators of Peta asked themselves what functionality enterprises actually use day-to-day in MCP workflows, and the answers — secure credential handling, fine-grained access control, audit logging, simple API integration — became the core feature set of Peta . By deliberately omitting the more exotic bells and whistles, Peta achieves a dramatically simpler design. One analysis summarized that Peta “delivers 80% of the value with 20% of the complexity” compared to something like ContextForge . This philosophy of minimalism is evident throughout Peta’s architecture and developer experience.
Strong Security Foundations: Peta’s foremost priority is security of tool access. It implements a built-in zero-trust model for secrets: API keys, tokens, and credentials for your tools are never exposed in plaintext to the AI or the client . Instead, Peta stores all sensitive secrets in an encrypted vault (within your infrastructure), and only injects the needed credentials into tool requests at execution time . This means an AI agent using a database tool or a SaaS API via Peta never actually “sees” the real database password or API key — it only gets a secure handle or temporary token. By containing secrets server-side, Peta drastically reduces the risk of leaks or unauthorized access, which is a critical concern in AI integrations. In practice, Peta functions as a combined MCP vault + gateway intercepting calls: it sits between your MCP clients and MCP servers, brokered as a proxy that substitutes any sensitive parameters with encrypted versions on the fly . Developers continue to use standard MCP client libraries; they just point them at Peta, which wraps the calls in an invisible security layer.
On top of secret protection, Peta provides an integrated policy engine and human oversight workflow. Through a web console (the Peta Desk), administrators can define per-agent and per-action policies — essentially, which AI agents are allowed to call which tools, and under what conditions . If an AI’s request violates a rule or is deemed high-risk, Peta can automatically pause the request and require human approval before proceeding . For example, you might allow an AI agent to read from an internal database tool freely, but flag any attempt to delete records or perform a financial transaction for manual approval. Peta handles this scenario out-of-the-box: it will halt the action and prompt a designated human reviewer in real-time. ContextForge users could theoretically build similar checks, but it would require custom development or external systems — whereas Peta bakes it in as a first-class feature . All actions and interventions are logged in an audit trail, providing traceability for compliance needs . Essentially, Peta treats security and governance not as afterthoughts but as core to the MCP workflow.
Lightweight Design and Easy Deployment: Unlike ContextForge’s heavyweight “everything” approach, Peta’s narrower scope keeps it lightweight and fast to deploy. The entire Peta system is distributed as a set of containerized components that can run on a single server, VM, or Kubernetes cluster with minimal configuration . The project emphasizes sane defaults and guided setup — reports suggest teams have gone from zero to a working MCP stack with Peta in an afternoon . In contrast, attempts to trial ContextForge often bogged down in multi-day (or multi-week) setup efforts due to its complexity . Peta’s lean footprint means fewer moving parts that can break. If you configure a dozen potential tools in Peta but only a few are actively used, the others sit dormant and consume no resources until needed . This on-demand activation saves overhead and avoids the need to run a fleet of microservices 24/7 “just in case.” In everyday use, developers have commented that Peta “just works” for common scenarios, without constant tweaking . Fewer configuration knobs and a smaller codebase translate to fewer mysterious bugs and easier maintenance. Importantly, Peta is self-hosted — you run it in your own environment (on-premises or in your private cloud) and retain full control . The Core and Desk components of Peta are open source, inviting transparency and community audit of its security mechanisms . This approach appeals to enterprises that need the confidence of inspecting the code or meeting strict internal compliance (and it sidesteps the external cloud trust issue we noted with Klavis). Peta even plans to offer a managed SaaS option for those who prefer hosted convenience, but its design fundamentally allows an organization to keep everything in-house if desired .
Why Peta Stands Out: In summary, Peta marries the crucial safety features enterprises want (secure secret storage, fine-grained access control, audit logging) with a streamlined, developer-friendly experience. It doesn’t attempt to replace every aspect of ContextForge — rather, it implements the 20% of features that cover 80% of use cases . This focus results in a product that is easier to understand and manage day-to-day. Developers exploring Peta often find it appealing because it reduces the time spent wrestling with the infrastructure or worrying about leaks, allowing them to iterate on AI capabilities faster. While Peta is a newer entrant and will undoubtedly evolve, its strong security foundation and pragmatic design have positioned it as an attractive choice for teams who might be overwhelmed by ContextForge’s complexity or wary of cloud-only solutions like Klavis. In an era of increasing concern over AI security and data protection, Peta’s approach of “secure by default, simple by design” resonates with many.
Conclusion
For developers working with MCP-based AI workflows, the tooling landscape is expanding quickly. ContextForge remains a powerful pioneer — essentially an entire toolbox for AI tool integration — but its complexity and early-stage nature mean it isn’t the best fit for everyone. We’ve seen how Klavis and Peta offer two distinct alternatives: one providing a cloud-based plug-and-play MCP platform, and the other delivering a security-centric, lightweight gateway you control.
Klavis may be ideal for those who want instant gratification — you get a robust set of features and don’t need to run anything yourself. It’s a great stepping stone for development teams who want to prototype or offload infrastructure concerns. Just be mindful of the cloud trade-off: ensure it aligns with your organization’s policies and long-term autonomy needs. Peta, on the other hand, appeals to those who value control and security above all. It asks you to run the show, but rewards you with deep safety guards and a cleaner, faster path to production. For many developer teams (especially in enterprises), that balance — getting critical MCP functionality without excessive complexity — is exactly what they’ve been looking for.
In choosing your MCP tooling, consider the priorities of your project or organization. If you require extensive features and don’t mind complexity, investing in ContextForge or a similar all-in-one solution could pay off. If you crave simplicity and speed and are comfortable with a managed service, Klavis offers a polished experience (just factor in the cloud aspect). And if you need a security-first, on-prem solution that covers common use cases with minimal fuss, Peta is a compelling new option to evaluate. The good news is that MCP’s ecosystem is maturing — whether you go with a powerhouse like ContextForge or a focused tool like Peta, you’re benefiting from the collective lessons of early adopters. Each alternative addresses different pain points, but all aim to help developers manage AI context more effectively. As the MCP standard continues to evolve, having these diverse tools at your disposal means you can pick the approach that best fits your team’s workflow and risk profile.
Ultimately, the goal is to empower you to build smarter AI integrations without getting bogged down in plumbing. ContextForge showed what’s possible; now tools like Klavis and Peta are refining how to make it practical. Happy hacking on your MCP workflows — and may your AI agents always have the context they need, in the most efficient and secure way possible.
