Bouncer, the AI-agent gateway with a deny button

Bouncer turns OpenAPI services into governed MCP endpoints, adding proxy URLs, tool policies, keys, quotas, spend caps, and call logs.

Landing page captured for the 2026-09-03 issue.

Field notes

The gateway accepts an OpenAPI or Swagger URL, generates MCP tools, and exposes them through a proxy rather than requiring an agent to change its original integration. Its visible policy example blocks `delete_repo` with a wildcard `delete_*` deny rule and returns a 403 decision. The page also names per-minute limits, daily quotas, hard spend caps, scoped keys, and request-level logging, while presenting WebMCP snippets as a supported endpoint format.
