Govern MCP-hosted tools through the same control plane that already inspects and routes AI traffic.
MCP tool support is only useful when teams can expose it deliberately. Posturio AI Gateway turns MCP-hosted tools into a governed surface: curated server catalogs, org approval, per-key scope, prompt-inspection gating, and request review after every tool-backed interaction.
That keeps MCP-hosted tools inside the same operator workflow as policy review, live keys, investigations, and model routing instead of treating tools as a parallel system.
What gets governed
Start with curated server catalogs, not arbitrary MCP endpoints.
The gateway should not become a tunnel to any remote MCP server a caller names. Posturio keeps MCP-hosted tools behind curated server definitions, synchronized tool catalogs, and explicit org-level enablement.
- Approved server catalog with sync health and last-sync status
- Per-server tool discovery mapped into a canonical Gateway tool list
- Org-level enablement so tools stay off until operators approve them
- Console visibility for enabled servers, enabled tools, and sync failures
Why this matters
Buyers evaluating MCP support usually care less about protocol novelty and more about whether engineering and security teams can keep tool access reviewable as adoption grows.
Keep org approval separate from per-key tool access.
Org enablement
Approve the tools the organization is allowed to use at all, regardless of which app key requests them.
Per-key scope
Issue a live key that can use every org-enabled tool, or narrow that key down to a smaller MCP tool set.
Operator clarity
Review key scope, tool enablement, and request traces from one shared console instead of stitching together separate views.
Run tool calls only after the same Gateway inspection path clears the prompt.
Tool execution should not bypass the control layer. In Posturio AI Gateway, MCP-hosted tools stay behind the same inspection path used for regular model traffic.
- Secrets and token patterns can block the request before any provider or MCP call
- PII and sensitive data policies can reroute or stop the tool-backed request
- Prompt-injection signals can suppress MCP tool execution in v1
- Tool-backed requests disable cache and keep redacted previews for operator review
Tool usage belongs in the same review queue as the rest of the Gateway.
Recent requests
Operators can see which requests invoked tools, which tool names ran, and which servers were involved.
Saved investigations
Longer-running review stays attached to the same request record instead of jumping into a separate MCP-only console.
Redacted traces
Arguments and results stay reviewable through redacted previews and hashes rather than raw payload dumps.
