Claude Code v2.1.321 makes Claude Fable 5.2 the default Fable model and fixes an MCP OAuth token leak
Anthropic's Claude Code release notes say Claude Fable 5.2 is now the default Fable model, with a 1M-token context window. It is priced at $8 input and $40 output per million tokens, and cache reads cost $0.20. The update also fixes a bug where MCP OAuth could pass refresh tokens to a different host after a server redirect.
- Verdict
- Use The public docs say it does what you need. We read the docs. We did not test it.
- For
- Developers and teams using Claude Code, especially those connecting to MCP servers or running claude remote-control
- Why it matters
- This release changes which model runs by default and what it costs, so teams should check their spending. The OAuth fix closes a path where credentials could leak, which makes it worth installing soon if you use MCP servers that sign in through OAuth. The new --settings flag for remote-control helps teams keep sessions set up the same way.
- Next check
- Check the full release notes for the cut-off read-only Bash fix. Also confirm Fable 5.2 pricing and availability on Anthropic's model documentation.
