If the server Claude Code talks to has already refused tool search during the current run, Claude Code now turns tool search off for the conversation. It logs: \"Tool search is off for this conversation: the endpoint refused it earlier in this process.\"\n\nThe check that decides whether search across MCP tools is unavailable now also counts that earlier refusal. MCP servers are add-ons that give Claude Code extra tools.\n\n**Why**\n\nClaude Code no longer keeps trying tool search against a server that rejects it.\n\n- Area: Tool Search\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
