A security layer that works with your existing MCP infrastructure. No changes to your MCP servers or clients required.
MCPS adds a digital identity and trust layer on top of existing MCP. Every agent that calls your MCP server proves who it is. Every response your server returns is digitally signed.
No modifications to your MCP server code. No changes to your tool definitions. No new protocol to learn. MCPS sits in front of your existing infrastructure as a verification layer.
One HTTP header carries the agent's identity. One signature proves the response is genuine. That's it.
MCPS and AgentPass are integrated into moov-io/watchman -- the open source sanctions screening platform used across financial services. 18,758 real OFAC entities. Live agent verification. Signed responses.
Zero trust architecture. Self-hosted. Open source SDKs (Apache 2.0). No third-party dependency.
