They can return listings of the resources they offer. Claude Code now limits how much of a listing it reads:\n\n- About the first 16 MB of a listing\n\n- About 1 million characters that take extra work to clean up and standardise\n\nA directory listing that is too large returns an error that lists no entries. Before, every entry was read with no size limit.\n\n**Why**\n\nThis protects Claude Code from an MCP server that sends a huge or harmful listing.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
