### Is the Sealgate MCP server safe to use?

Sealgate scores 93 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Sealgate MCP server expose?

Sealgate exposes 2 tools: list_mcp_servers, get_session_status. Their descriptions and schemas cost roughly 207 tokens of context every time the server is loaded.

### Is the Sealgate MCP server still maintained?

Sealgate is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sealgate MCP server under?
