MCP for websites

Turn your website into an MCP interface.

MCP gives agents a way to call tools. Arachne applies that idea to websites, turning messy human-facing surfaces into governed agent-callable interfaces.

Why MCP matters

MCP gives agents a safer way to interact with software.

A browser page is a poor interface for autonomous software. MCP-style tools let agents ask for structured capabilities and receive structured results.

Discoverable tools

Agents can see what capabilities exist before guessing how to act.

Typed inputs

Actions can require specific fields instead of relying on vague forms and page context.

Approval boundaries

Sensitive actions can require review instead of being executed blindly.

Website to MCP

How Arachne maps websites into tools.

Arachne looks at public surfaces and produces a structured interface around what the business already exposes.

Pages become resources

Core public content is exposed as agent-readable resources with source links.

Forms become draft tools

Forms can be represented as draft-only or approval-gated tool calls.

Pricing becomes structured

Plans, fees, discounts, and eligibility notes can be returned in a predictable shape.

Policies become gates

Rules define what agents can read, draft, request, or execute.

Design partner program

Give agents a front door without rebuilding your website.

Selected design partners can pilot a hosted Shadow API that exposes MCP-compatible capabilities for one authorized domain.

FAQ

Quick answers

Short answers for teams evaluating agent-readiness, MCP, and hosted Shadow APIs.

Do I need an existing API?

No. Arachne can start from public website surfaces and build a governed Shadow API layer.

Is MCP only for developers?

MCP is technical under the hood, but the buyer value is simple: agents get a safer way to use your business.

Can write actions be blocked?

Yes. Write actions can be draft-only, approval-required, or disabled.
