Add Index-Now.ru MCP server

[arseniigruzdev]

Adds servers/index-now-ru-mcp.yaml for the public remote MCP server io.github.arseniigruzdev/index-now-ru.

• Transport: HTTP streaming (https://index-now.ru/mcp)
• Source: https://github.com/arseniigruzdev/index-now-ru-mcp
• Authentication: user-provided Bearer API key; no secret is included in this PR.
• License and version match the canonical public manifest (CC0-1.0, 1.0.0).

hi @arseniigruzdev,
The YAML validates successfully and the public manifest confirms the endpoint, Streamable HTTP transport, version, and Bearer authentication.

Before merging, please address the following:

1. Add a tested install configuration or another machine-readable connection configuration. The MCP endpoint currently appears only inside the description, so registry consumers cannot automatically connect or pass the required Bearer API key.

2. The repository field is expected to point to the server’s source code, but the linked repository contains only metadata and documentation. Please link the actual source repository or clearly disclose that the service implementation is closed-source.

3. CC0-1.0 applies only to the metadata repository, not necessarily to the hosted MCP service. Please remove the license field or replace it with the service’s actual license.

4. Please include the actual tool definitions from an authenticated tools/list response and validate them through the published connection configuration.

The service appears to be real and reachable, but the current registry entry is not complete enough for users to connect to and independently verify.
