Model Context Protocol (MCP) — Primer
The Model Context Protocol (MCP) standardizes how clients discover and invoke tools/resources from tool servers for AI agent contexts.
Why it matters
Standards reduce risk and vendor lock‑in. We implement this spec across our Studios and runtime so policy is portable.
Where it’s enforced
- Gateway: pre‑execution gating (plan/schema pins, params/egress)
- Shield: inline budgets/stream caps/content checks
- PDP: decisions with constraints/obligations/TTL
- IdP: passports, token exchange, consent/DPoP
How it works (high level)
MCP defines a protocol between clients and tool servers for model context. Clarify roles (client/server/tools), transport vs schema, version negotiation, and policy/security hooks.
