The Model Context Protocol gives agents hands. Security is what decides whether those hands can reach production — and proves what they touched. iTechSmart governs and receipts every MCP tool call.
MCP (Model Context Protocol) standardizes how AI agents call external tools. That's powerful — and it's the whole risk surface: a tool call can restart a service, move data, or spend money. MCP security is about controlling which calls are allowed, enforcing that control before execution, and proving what actually ran. iTechSmart's MCP server puts every side-effecting call through Arbiter policy enforcement and returns a ProofLink receipt in the response, so agent tool use is both governed and auditable.
Policy enforcement before any side-effecting tool call executes
Blast-radius, time-window, and approval controls on high-impact tools
A cryptographic receipt returned with each governed call
A discoverable, documented tool surface with least-privilege defaults
Read-only, rate-limited public access for safe evaluation
Agents wired directly to production tools with no policy layer
Tool calls that leave no verifiable record of what happened
All-or-nothing credentials with no per-action limits
No way to prove, after an incident, which call caused what
Because MCP tool calls can take real actions on infrastructure, data, and money. Without a policy and proof layer, an agent's tool access is an unguarded path to production.
