### Describe the bug get_file_contents returns (today) this format: {"jsonrpc":…"2.0","id":7,"result":{"content":[{"type":"text","text":"successfully downloaded text file"},{"type":"resource","resource":{"uri":"repo://MY_ORG/MY_REPO/contents/logic/index.js","mimeType":"text/plain; charset=utf-8","text":"module.exports = require('./src/tasks-service');\n"}}]}} When using get_file_contents, and getting such response, cursor continues with an error: "content type 'resource' not supported" ### Affected version Taken from docker logs: GitHub MCP Server running on stdio {"jsonrpc":"2.0","id":1,"result":{"protocolVersion":"2025-03-26","capabilities":{"logging":{},"resources":{"subscribe":true,"listChanged":true},"tools":{"listChanged":true}},"serverInfo":{"name":"github-mcp-server","version":"v0.5.0"}}} ### Steps to reproduce the behavior Ask to summarize readme in some repo. eg https://github.com/github/github-mcp-server ### Expected vs actual behavior readme summarized. Actual: "content type 'resource' not supported" ![Image](https://github.com/user-attachments/assets/2d08ce29-4cf7-43fc-a7ae-97621b6aaee8) Previously (from memory) github used to return response in base64... so perhaps something had changed in the response ### Logs Paste any available logs. Redact if needed.

This also occurs with the GitHub remote MCP.
