The project converts existing OpenAPI specs into hosted MCP servers, avoiding the need to rebuild APIs. The author predicts a gradual shift toward MCP adoption, driven by AI's need for consistent interaction with software.", "body_md": "Over the last year, I've noticed an interesting pattern.\n\nA few years ago, every software company wanted a REST API.\n\nToday, many of those same companies are asking a different question:\n\n\"How do we make our product work with AI agents?\"\n\nThat shift made me wonder:\n\n**Will having an MCP server eventually become as common as having an API?**\n\nI'm not convinced we're there yet.\n\nBut I do think we're heading in that direction.\n\nLet's discuss why.\n\nThink back to the early days of APIs.\n\nMany businesses didn't expose one publicly.\n\nIntegrations were built manually.\n\nPartners requested CSV exports.\n\nDevelopers wrote custom scripts.\n\nEverything worked—but only until the next integration request arrived.\n\nEventually, APIs became the standard because they reduced friction for everyone involved.\n\nNow AI is creating a similar moment.\n\nWhen people use tools like ChatGPT, Claude, Cursor, or other AI assistants, they don't want to switch between five browser tabs just to complete a task.\n\nInstead, they expect to say something like:\n\n\"Create a customer in our CRM.\"\n\nor\n\n\"Generate this invoice.\"\n\nor\n\n\"Show today's failed deployments.\"\n\nFor that to work, the AI needs a reliable way to interact with your product.\n\nThat's where the conversation around MCP starts.\n\nThis is probably the most common question.\n\nTechnically, AI *can* call a REST API.\n\nBut here's the problem.\n\nREST APIs were designed for software developers.\n\nDevelopers read documentation.\n\nDevelopers understand authentication.\n\nDevelopers know which endpoint to call first.\n\nDevelopers combine multiple requests together.\n\nAI agents don't \"read documentation\" the same way humans do.\n\nThey need structured descriptions of available actions.\n\nThey need context.\n\nThey need discoverable tools.\n\nThat's exactly what MCP provides.\n\nThis is probably the biggest misconception I see online.\n\nSome people talk about MCP as if REST APIs are becoming obsolete.\n\nI don't think that's true.\n\nYour API is still the foundation.\n\nThe MCP server simply becomes another interface for accessing it.\n\nA simple way to think about it is:\n\nOne doesn't replace the other.\n\nThey solve different problems.\n\nHistorically, if you wanted your product to work with different platforms, you often built separate integrations.\n\nOne for Slack.\n\nOne for Zapier.\n\nOne for Teams.\n\nOne for internal automation.\n\nNow imagine doing the same thing for every AI platform that appears over the next few years.\n\nThat doesn't seem sustainable.\n\nStandards become valuable when ecosystems grow.\n\nThat's why MCP has attracted so much attention.\n\nWhile working on **0mcp** ([https://0mcp.io](https://0mcp.io)), one thing became very clear.\n\nMost teams already have everything they need.\n\nThey have:\n\nThe missing piece isn't the API.\n\nIt's making that API understandable to AI systems.\n\nThat's why 0mcp focuses on turning existing OpenAPI specifications into hosted MCP servers instead of asking teams to rebuild everything from scratch. If you're curious how the workflow looks, the documentation at ** https://docs.0mcp.io** walks through the process from importing an API to exposing AI-ready tools.\n\nProbably not.\n\nAt least, not today.\n\nIf your software has no need to interact with AI agents, adding an MCP server just because it's trendy doesn't make much sense.\n\nTechnology should solve a real problem.\n\nBut if your customers are already asking questions like:\n\n...then it's worth paying attention.\n\nI don't think every product will suddenly launch an MCP server next month.\n\nBut I do think we'll see a gradual shift.\n\nFive years ago, companies proudly announced they had an API.\n\nToday, nobody makes that announcement because it's expected.\n\nI wouldn't be surprised if MCP follows a similar path.\n\nNot because it's fashionable.\n\nBut because AI tools need a consistent way to interact with software.\n\nI wouldn't recommend throwing away your existing APIs.\n\nInvest in them.\n\nKeep your OpenAPI specification up to date.\n\nDesign clear endpoints.\n\nGood APIs become even more valuable in the AI era.\n\nWhen you're ready to expose those capabilities to AI clients, standards like MCP can build on top of the work you've already done rather than replacing it.\n\nThat's one of the reasons we built **0mcp**—to help teams reuse the APIs they already have instead of starting from zero. You can learn more on the homepage ([https://0mcp.io](https://0mcp.io)) or explore the guides and examples in the documentation ([https://docs.0mcp.io](https://docs.0mcp.io)).\n\nThis is still an evolving space.\n\nSome teams are already exposing MCP servers.\n\nOthers are experimenting.\n\nMany are still deciding whether they need one at all.\n\nSo I'm curious:\n\n**Do you think MCP servers will become as common as REST APIs, or will they remain a niche tool for AI-focused products?**\n\nLet's discuss in the comments.", "url": "https://wpnews.pro/news/is-every-saas-company-going-to-need-an-mcp-server", "canonical_source": "https://dev.to/bhavyshekhaliya/is-every-saas-company-going-to-need-an-mcp-server-1l79", "published_at": "2026-08-01 01:53:35+00:00", "updated_at": "2026-08-01 02:10:21.420892+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-infrastructure"], "entities": ["0mcp", "ChatGPT", "Claude", "Cursor", "Slack", "Zapier", "Teams"], "alternates": {"html": "https://wpnews.pro/news/is-every-saas-company-going-to-need-an-mcp-server", "markdown": "https://wpnews.pro/news/is-every-saas-company-going-to-need-an-mcp-server.md", "text": "https://wpnews.pro/news/is-every-saas-company-going-to-need-an-mcp-server.txt", "jsonld": "https://wpnews.pro/news/is-every-saas-company-going-to-need-an-mcp-server.jsonld"}}
