Choosing an MCP server means deciding how AI agents will access your company's data, and that decision carries real weight when the data is revenue-critical. The right choice depends on hosting model (self-hosted vs managed), security and compliance standards, integration breadth, and vendor support. For GTM and RevOps teams, the deciding factor is which server can be trusted with governed, compliant data access – not which one has the most integrations.
You already know you need MCP. What you might be staring at now is a fast-growing, developer-first ecosystem, wondering which piece of software actually fits your GTM stack.
MCP itself isn't a standalone software product. It's a connection standard that lets AI assistants like Claude or ChatGPT access external data and tools. What you're really choosing is a server that sits between those assistants and your company's revenue data, not just a tool for coding or general AI-agent tinkering.
Here's a decision framework built around what matters when the data flowing through the server is customer and prospect data.
MCP servers mostly differ on three things: hosting model, security posture, and how much setup and maintenance your team takes on itself. Once you strip away the marketing, most comparisons come down to a handful of decision factors.
The true distinctions that are important to evaluate are:
A common mistake is comparing the integration count or setup speed alone. For a GTM team, the real question is whether what flows through the server stays governed and compliant the whole way, rather than how many tools it connects to.
Self-hosted gives you more control but needs ongoing engineering time. Managed trades some of that control for speed and support. Neither is universally right – it depends on team size and how mature your existing infrastructure already is.
Here is a quick way to sense-check where you land:
|
Self-hosted |
Managed (general-purpose) |
Managed (data-specific) |
|
|
Security/ compliance |
Your responsibility end-to-end |
Varies by vendor |
Built around the data's compliance requirements |
|
Hosting control |
Full control |
Limited |
Limited, by design |
|
Governed data access |
You build the governance |
Rarely a focus |
Core to the product |
|
Ecosystem breadth |
Whatever you integrate yourself |
Usually broad |
Usually narrower, deeper on one data type |
If your team is small and already stretched, or if the data involved is sensitive enough that "we'll build governance later" isn't a real option, then managed – and specifically a data-specific managed option – tends to be the most sensible option. If you've got the engineering capacity and the data isn't the sensitive part of the equation, self-hosted keeps you in full control.
Ask yourself three questions before deciding:
This is the part most evaluations skip until it's too late, and it's the one that actually matters once revenue data is involved.
Before trusting any MCP server with your data, check for:
A feature comparison table usually doesn’t provide this information.
"What I've seen is that the deeper you get into an enterprise evaluation, the less it becomes about ticking feature boxes and the more scrutiny there is around trust.
Security and compliance teams want to know how their data is handled, where it goes, and what controls and audit trails exist around it.
A product can look great on paper, but if a vendor can't answer those questions confidently and transparently, it can quickly become a blocker."

Cost depends entirely on hosting model. Free or open-source options don't have a subscription fee, but they carry engineering and maintenance cost instead – someone on your team is the ongoing cost. Managed options typically price on usage, seats or data volume.
There's no universal number to quote here, but there is a useful mental model: with self-hosted, you're trading a subscription line item for engineering hours; with managed, you're paying to not have that be your team's problem. Neither is automatically cheaper. It depends on how much that engineering time is worth to you elsewhere.
There's no single best option. It depends on hosting preference, compliance needs, and what's already in your stack – which is exactly why most "best MCP server" lists online are answering the wrong question.
Microsoft, Anthropic, and GitHub all publish their own reference or example MCP servers, aimed squarely at developers building on their respective platforms. Microsoft's Azure MCP Server, GitHub MCP Server, and Azure AI Foundry MCP Server are genuinely useful if you're building developer tooling on that stack. They're a different tool for a different job than a managed, data-specific option built for GTM teams.
That's where a data-specific managed option earns its place. Cognism's upcoming MCP connector gives AI tools like Claude and ChatGPT governed, read-only access to verified B2B company and contact data, without your team building and maintaining a custom integration per tool.
The right MCP server for a coding assistant and the right one for your GTM stack are rarely the same choice. If what's flowing through it is customer and prospect data, the questions worth asking are about governance, compliance, and who's accountable for both – avoid simply focusing on which one has the longest integration list. Keep your eyes peeled for Cognism’s upcoming MCP connector if you're specifically weighing this up for revenue data.
