MCP (Model Context Protocol)

Who launched it and why

• MCP was introduced by Anthropic (announced Nov 25, 2024) to solve fragmented AI-to-system integrations.
• It was created so model applications could connect to tools/data via one protocol rather than bespoke per-integration connectors.
• The protocol is open and ecosystem-supported across multiple clients, IDEs, and infrastructure providers.

What it is

• A JSON-RPC-based protocol defining hosts, clients, and servers for agent context/tool interoperability.
• Core server primitives include resources, prompts, and tools; clients can expose features like sampling and elicitation.
• MCP is transport-agnostic in practice and designed for composable, capability-negotiated integration patterns.

Who it is for

• AI product teams building assistants, copilots, and agent workflows that need reliable external capabilities.
• Enterprise platform teams exposing internal APIs/knowledge systems once for many agent clients.
• Security and governance teams requiring explicit boundaries for tool invocation and context exposure.

How to implement it (core architecture)

1. Model capability surfaces first: identify tool calls vs read-only resource endpoints and define strict schemas.
2. Implement an MCP server with validation, authentication, and policy enforcement before enabling write actions.
3. Integrate an MCP client in your host app, then run contract tests for handshake, invocation, and error semantics.
4. Deploy with observability: trace request IDs, tool execution outcomes, latency, and denied-authorizations.

CMS and platform implementation playbook

WordPress

• Expose read resources from WP REST API (posts, taxonomies, metadata) and custom plugin endpoints for controlled tool actions.
• Wrap privileged mutations (publish/update/delete) with role-aware permissions and explicit user confirmations.
• Use custom post types + ACF structures for predictable schema-mapped context payloads.

Shopify

• Map MCP tools to Admin API and Storefront API operations (catalog lookup, inventory checks, order workflows).
• Isolate write operations behind app-level scopes and enforce checkout/order action policies.
• Use MCP resources for product/collection knowledge and tools for transactional operations.

Webflow

• Use CMS API for structured content retrieval as MCP resources and keep editorial writes gated.
• Publish workflow-safe tools for draft updates, staged publish checks, and schema consistency validation.
• Pair Webflow CMS collections with protocol-level content typing to reduce agent hallucination risk.

Headless (Next.js, Astro, custom)

• Place MCP server in your backend/API layer close to source-of-truth services and business logic.
• Use typed SDK schemas shared between frontend agent clients and server tool contracts.
• Implement environment-specific capability toggles so staging and production policies differ safely.
