The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the io.mcprating/gateway MCP server?
io.mcprating/gateway is an MCP server listed in the public MCP registry as io.mcprating/gateway. Find MCP servers in the MCP Rating index and connect on demand, with env vars scoped per server. This page covers its npm package (@mcp-rating/gateway).
Is the io.mcprating/gateway MCP server safe to use?
io.mcprating/gateway scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 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 io.mcprating/gateway MCP server expose?
io.mcprating/gateway exposes 13 tools: mcp_discover, mcp_connect, mcp_disconnect, mcp_list_active, mcp_server_info, and 8 more. Their descriptions and schemas cost roughly 1,738 tokens of context every time the server is loaded.
Is the io.mcprating/gateway MCP server still maintained?
io.mcprating/gateway is still listed as active in the MCP registry. We last reached this channel on 5 November 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 io.mcprating/gateway MCP server under?
io.mcprating/gateway declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the io.mcprating/gateway MCP server?
VerifyMCP ran 16 checks on io.mcprating/gateway, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
