Tollgate
Teams letting AI agents call real tools get a checkpoint in front of every call — an MCP proxy that allows, holds for a person, or blocks each tool call and scans what tools return for planted instructions. On 229 held-out calls it caught 96.3% of risky calls in a median 321 ms, about 12x faster and 60x cheaper than asking Gemini on every call.
