Document how to use the OKF4net MCP server with JetBrains Rider (and IntelliJ)

[jchable]

Difficulty / est. effort: ~1-2h, small-medium (docs + config)

Context: JetBrains Rider is the JetBrains .NET IDE (and IntelliJ the JVM flagship); the AI Assistant supports MCP. A recipe lets Rider/IntelliJ users consult an OKF bundle via okf-mcp (a standard stdio MCP server; src/OKF4net.Mcp/README.md documents only Claude today).

Files to touch: src/OKF4net.Mcp/README.md (add a ### Use with JetBrains Rider (and IntelliJ) section).

What to do:

1. Add the section covering Rider and, where identical, IntelliJ IDEA.
2. Document how to register the server via the AI Assistant MCP settings (Settings → Tools → AI Assistant → Model Context Protocol) and/or an mcp.json, with command: "okf-mcp" + bundle-path args. Verify the exact path/schema and minimum IDE version against current JetBrains docs and link them.
3. Mention OKF_MCP_READONLY=1.

How to verify:

1. dotnet tool install -g OKF4net.Mcp (installs okf-mcp).
2. Point the config at a small test bundle (e.g. tests/fixtures/ has example bundles, or make a throwaway one with a single type:-tagged concept).
3. Restart the editor, open its MCP/agent panel, and confirm the okf server connects and the OKF tools appear (okf_read_concept, okf_browse, okf_graph, okf_search, okf_validate_bundle, okf_changes_since).
4. Ask the assistant to read or browse a concept from the bundle and confirm it works. Add a OKF_MCP_READONLY=1 note for read-only use.

Docs-only change — no build impact — but run dotnet build OKF4net.sln to be safe.

Good to know: Model the new section on the existing "Use with Claude Desktop" block in src/OKF4net.Mcp/README.md (same command: "okf-mcp" + bundle-path args, or OKF_BUNDLE_ROOT env). MCP is a standard stdio protocol, so the server itself needs no change — only the client-side config differs. See CONTRIBUTING.md. If you get stuck on a config format, open a Discussion.

@jchable can I try to do this?

@jchable I currently have issues to have it working with Rider and I am not sure why, I will talk to JetBrains to see what is going on. But, I made it working with VS Code, so I could start with #16, could you assign it to me?
