[Bug/Improvement] Editor/VS Code reports "invalid JSON parameters"

[vjaykrsna]

The MCP exposes JSON schemas that include newer JSON Schema meta-features. The JSON Schema validator used by VS Code / the extension doesn't support those features, so editors show "invalid JSON parameters" and the MCP tool schemas are rejected.

Reproduction: Use the MCP with VS Code / Copilot (or the extension that integrates MCP tools). The logs show messages like: "Tool firecrawl_scrape has invalid JSON parameters: The schema uses meta-schema features ($dynamicRef) that are not yet supported by the validator."

Can we make firecrawl backward compatible?
I am unable to use firecrawl mcp in Github Copilot currently
other ide like gemini cli and qwen cli throw error while tool call sometimes too
