The MCP docs now say that
@modelcontextprotocol/serverand@modelcontextprotocol/sdkare optional peers ofagents, so you install the one your server uses yourself. They also bump the pinned MCP versions to the ones the current Agents release expects (server/client2.3.1,sdk1.32.1).Docs for cloudflare/agents#2634, which stops
agentsfrom installing the SDK v1 server stack (express,cors, ...) for apps that do not serve MCP (cloudflare/agents#2209):handler-apiandmigrate-to-mcp-sdk-v2: optional-peer note and updated versions. The migration guide also warns legacy servers that import@modelcontextprotocol/sdkwithout declaring it to add it before upgrading.agent-api(McpAgent): install step for@modelcontextprotocol/sdk.transport(RPC) andclient-api: the MCP client side needs neither package.Merge after cloudflare/agents#2634 is released.
