SentinelMCP is a stateless enterprise policy firewall and token-cost proxy for the Model Context Protocol. You drop it in front of any MCP server and every tool call is checked for identity, policy and budget before it reaches your infrastructure. There is no database and no sticky sessions, so there is nothing new to operate at 3am, and a demo image runs with a single docker command.

Validate identity, policy and budget on each tool call before it is forwarded.
Use the proxy as a cost gate as well as a policy gate.
Run the published demo container with one docker command.
