Add PolicyLayer/Intercept to Security section

[s-a-m-a-i]

Adding PolicyLayer/Intercept — an open-source MCP proxy that enforces YAML policies on tool calls (rate limiting, spending caps, argument validation, audit logging).

It sits at the transport layer between agent and server, so enforcement is deterministic and model-agnostic. Works with any MCP server.

Apache 2.0 licensed.

Hey,

To ensure that only working servers are listed, we're updating our listing requirements.

Please complete the following steps:

1. Ensure your server is listed on Glama. If it isn't already, submit it at https://glama.ai/mcp/servers and verify that it passes all checks (including a successfully built Docker image and a release).

2. Update your PR by adding a [glama](https://glama.ai/mcp/servers/...) link immediately after the GitHub repository link, pointing to your server's Glama listing page.

If you need any assistance, feel free to ask questions here or on Discord.

P.S. If your server already has a hosted endpoint, you can also list it under https://glama.ai/mcp/connectors.
