If you are weighing other options, here are the strongest alternatives, starting with Sealgate. Last updated: September 2026 TOP ALTERNATIVE ## Sealgate A runtime agentic data firewall that blocks dangerous tool calls before they execute, scans tool traffic for data loss and prompt injection, discovers shadow MCP servers on the device, and streams a provable audit trail to your SIEM. Bottom line: Microsoft MCP Gateway is infrastructure for routing MCP traffic on Kubernetes, not a security product; Sealgate is a runtime firewall that adds inline enforcement, DLP, injection defense, shadow-MCP discovery and enterprise governance. - Sealgate blocks dangerous tool calls inline and scans traffic for data loss and prompt injection; Microsoft MCP Gateway is a routing proxy with RBAC on server access and no tool-call inspection. - Sealgate runs a device-level agent and discovers shadow MCP servers; Microsoft MCP Gateway is a Kubernetes cluster component with no on-device presence. - Sealgate keeps local stdio servers on the device through a tunnel; Microsoft MCP Gateway deploys servers as cluster pods. - Sealgate governs the agent CLI as well as MCP; Microsoft MCP Gateway routes MCP session traffic.

Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | Deploy as pods (No) | | Local stdio servers stay on-device. The server keeps running on the machine, with no host-and-lift and no HTTP re-expose. | ✓ Yes | ✕ No | | Device-level management. An endpoint agent that discovers and governs MCP activity on the device itself. | ✓ Yes | ✕ No | | Interface coverage. Whether the gateway governs only the MCP protocol, or the agent CLI and LLM API too. | MCP + CLI (Yes) | MCP only (No) | | Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact. | ✓ Yes | ✕ No | | DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime. | ✓ Yes | ✕ No | | Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks. | ✓ Yes | ✕ No | | Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry. | ✓ Yes | ✕ No | | Shadow MCP discovery. Finds unauthorized MCP servers before they are used. | ✓ Yes | ✕ No | | Provable per-call audit. A receipt for every call: agent, tool, policy version, result. | ✓ Yes | – Not publicly verified | | SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs. | ✓ Yes | – Not publicly verified | | SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access. | ✓ Yes | ~ Partial | | Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals. | ✓ Yes | ~ Partial | | Self-host, on-prem or VPC. Run it in your own environment for data residency. | ✓ Yes | ✓ Yes | | Compliance mapping. Evidence mapped to SOC 2, NIST AI RMF and the EU AI Act. | ~ Partial | ✕ No | | Low latency overhead. Minimal added latency on the tool-call path. | ✓ Yes | – Not publicly verified | | Open source core. An open, inspectable core rather than a closed proxy. | ✕ No | ✓ Yes | ✓ Strong or native ~ Partial or via a partner ✕ Not offered – Not publicly verified ## Other Microsoft MCP Gateway alternatives
