Input file is not valid JSON

Type URI: https://modeled-information-format.github.io/mif-rs/references/errors/mif-mcp-invalid-json/v1 HTTP status: 400 Exit code: 2 Emitted by: mif-mcp (McpError::Json)

failed to parse {path} as JSON: {source}

The mif-mcp validate_mif_document/ingest_mif_document tools read path successfully but it did not parse as JSON — reached only for the already-JSON-LD input branch, since a markdown-with-frontmatter input takes a different parse path entirely.

No suggested fix or code action is attached to this variant — the emitted envelope carries only the standard RFC 9457 members plus exit_code.
