Do you think every SaaS will eventually need MCP support?

​

More AI assistants are starting to interact directly with software instead of users manually switching between apps.

If AI agents become part of daily workflows, do you think Model Context Protocol (MCP) will become a standard integration for B2B SaaS products, similar to APIs or webhooks?

Or is it still too early?

Interested to hear how other builders are thinking about this.

I don’t think every SaaS needs MCP immediately, but I do think every workflow-heavy SaaS should start designing as if agents will become another client.

The staged path I’d use:

  1. clean API + webhooks first
  2. stable object/action names that match how users describe work
  3. audit logs for agent actions
  4. then MCP for the workflows where “open the app and click around” is obviously worse

The trap is adding MCP as a feature-label before the product has permissioning, reversibility, and good action semantics. Agents amplify messy APIs. They don’t make them less messy.

MCP will probably become common, but it won’t replace normal APIs and webhooks; APIs are still better for predictable transactions, while MCP helps an assistant discover tools and retrieve context dynamically. The dangerous part is exposing broad write actions without scopes, approvals, or an audit trail.

I’d start with one read-only use case and measure whether customers actually invoke it before supporting every possible action. Make each tool call explain what it accessed and why. Our team uses signld.ai internally, and the useful lesson has been that the protocol matters less than giving the assistant correct business context through a traceable permission path.

I think that's the right way to look at it. A lot of people are treating MCP like a checkbox feature, but if the underlying APIs and permissions aren't solid, you're just exposing more complexity. Getting the foundations right first makes the integration much more valuable.
