What
The name you give a connector in a manifest is no longer restricted to letters, digits, spaces and a few punctuation marks. Any 1 to 64 characters are allowed except control characters, line breaks, unusual spaces and text-direction marks, and the name cannot start or end with a space or invisible character. A new check also rejects names that read like a host: prefix or like an internal id.
Details
- Names shaped like the internal
claude_ai_ormcp__prefixes are rejected too. - The change swaps an allow-list for a deny-list, so accented and non-Latin names now pass.
Evidence
`must not read as \host:\ or be shaped like an id or a \claude_ai_\u2026\/\mcp__\u2026\ prefix`
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
