Safety notes— missing✓The official TypeScript SDK is a protocol library; your MCP server's tool handlers, resources, prompts, transports, and auth logic determine the real risk. Treat every registered tool as a model-callable API endpoint and validate inputs, enforce permissions, bound side effects, and sanitize failures. HTTP and framework middleware deployments need host validation, authentication, TLS, request limits, logging policy, and abuse controls. The upstream main branch documents v2 pre-alpha work; use the production v1 package for stable deployments unless you intentionally accept alpha API churn.✓Agents can call function tools, hosted tools, MCP tools, realtime tools, and sandbox agents; treat every tool as an API endpoint with explicit authorization, input validation, rate limits, and side-effect controls. Sandbox agents can inspect files, run commands, apply patches, and carry workspace state across longer tasks; restrict workspace scope and require human approval before destructive or high-impact actions. Cloudflare Workers support is described upstream as experimental; review runtime compatibility, secrets, outbound network access, logging, request limits, and `nodejs_compat` behavior before production use. Guardrails help validate inputs and outputs, but they do not replace permission checks, least-privilege credentials, audit logs, or human review for risky operations. Handoffs and agents-as-tools can delegate work across agents; document which agent owns each tool, decision, retry, rollback, and escalation path.✓Strands agents can call custom tools, MCP tools, vended tools, model providers, HTTP APIs, file editors, shell tools, sandboxes, and multi-agent orchestrators; every tool needs explicit permission and side-effect review. The README says both SDKs default to Amazon Bedrock, so unattended examples may use AWS credentials and hosted model access unless the provider is changed. TypeScript exports include vended file-editor, HTTP request, bash, sandbox, intervention, plugin, telemetry, and session-storage surfaces; keep production credentials and filesystem scope narrow. Python optional extras include provider, A2A, bidirectional streaming, OpenTelemetry, Cedar, SageMaker, and other integrations; install only the extras needed for the current runtime. Hooks, guardrails, structured output validation, steering handlers, and traces help control behavior, but they do not replace authorization, audit logs, human approval, rollback plans, or domain-specific tests.
Privacy notes— missing✓MCP clients and servers built with the SDK may expose tool arguments, tool results, resource contents, prompt templates, OAuth state, errors, traces, and logs. Avoid returning secrets, private file contents, customer data, privileged paths, internal identifiers, or operational metadata through schemas, examples, errors, or logs. Document which MCP client, server, model provider, transport, middleware layer, and logging system can observe each request.✓Prompts, instructions, tool arguments, tool outputs, session history, traces, realtime audio events, sandbox files, logs, provider responses, and errors may contain user or workspace data. Do not expose secrets, tokens, private file paths, customer records, credentials, internal identifiers, raw exceptions, or voice transcripts through traces, logs, prompts, tool schemas, or examples. When using MCP servers, hosted tools, session stores, worker logs, observability systems, or deployment platforms, review each service's retention, access control, and third-party data handling separately. If sandbox agents operate on repositories or user files, define which files can be mounted, modified, committed, uploaded, logged, or returned to the model.✓Prompts, chat history, system prompts, tool schemas, tool arguments, tool results, traces, hooks, model responses, streaming events, structured outputs, and errors can be sent to configured model providers or observability backends. MCP servers and vended tools may expose local files, shell output, HTTP responses, cloud resources, SaaS records, credentials, source code, and user data to the agent loop. AWS, Anthropic, OpenAI, Gemini, Ollama, LiteLLM, SageMaker, A2A, OpenTelemetry, and other integrations each have separate logging, retention, and access-control behavior. Do not publish AWS credentials, provider API keys, Bedrock model access details, OpenTelemetry endpoints, trace IDs containing sensitive metadata, filesystem paths, or generated run logs in public issues or PRs.
Prerequisites— none listed
  • Node.js, Bun, or Deno runtime compatible with the SDK generation you choose.
  • A decision between production v1 package usage and the upstream v2 alpha split-package track.
  • A target MCP transport, such as stdio for local tools or Streamable HTTP for hosted servers.
  • Authentication, authorization, and side-effect boundaries for any production MCP server.
  • Node.js 22 or later, Deno, Bun, or an explicitly reviewed Cloudflare Workers runtime with `nodejs_compat` enabled.
  • OpenAI API credentials or another configured model provider supported through the SDK's provider-agnostic routes.
  • A reviewed tool boundary for function tools, hosted tools, MCP tools, handoffs, sandbox agents, and any external systems the agent can call.
  • A TypeScript schema strategy for `zod`, tool inputs, tool outputs, guardrails, and runtime validation.
  • Python 3.10 or newer for the Python SDK, or Node.js 20 or newer for the TypeScript SDK.
  • AWS credentials and Amazon Bedrock model access for the default provider, or configured credentials for Anthropic, OpenAI, Gemini, Ollama, LiteLLM, Mistral, Writer, SageMaker, or another selected provider.
  • A reviewed tool boundary for built-in tools, custom tools, MCP servers, HTTP calls, file editing, shell execution, sandboxing, A2A, and multi-agent workflows.
  • OpenTelemetry, tracing, logging, and retention decisions before using Strands for production agents.
