MCP result-size override v2.1.91

MCP server authors can now raise the truncation cap on a specific tool by setting anthropic/maxResultSizeChars in the tool's tools/list entry, up to a hard ceiling of 500K characters. The cap used to be global, so tools that occasionally returned inherently large payloads like database schemas or full file trees hit the default limit and got persisted to disk with a file reference. Per-tool overrides keep those results inline when the tool really needs them.

Annotate the tool in your server's tools/list response:

{
  "name": "get_schema",
  "description": "Returns the full database schema",
  "_meta": {
    "anthropic/maxResultSizeChars": 500000
  }
}

Plugin executables on PATH v2.1.91

Place an executable in a bin/ directory at your plugin root and Claude Code adds that directory to the Bash tool's PATH while the plugin is enabled. Claude can then invoke the binary as a bare command from any Bash tool call, with no absolute path or wrapper script needed. Handy for packaging CLI helpers next to the commands, agents, and hooks that call them.

Add a bin/ directory at the plugin root:

my-plugin/
├── .claude-plugin/
│   └── plugin.json
└── bin/
    └── my-tool
