MCP (Model Context Protocol)
Open standard for connecting AI clients to external tools, resources, and workflows.
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)
- Model capability surfaces first: identify tool calls vs read-only resource endpoints and define strict schemas.
- Implement an MCP server with validation, authentication, and policy enforcement before enabling write actions.
- Integrate an MCP client in your host app, then run contract tests for handshake, invocation, and error semantics.
- 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.
