Add Amazon Bedrock Guided MCP Power

[dgallitelli]

Proposal: Add amazon-bedrock Guided MCP Power

What

A Guided MCP Power for building generative AI applications on Amazon Bedrock, integrating two MCP servers from awslabs/mcp.

Coverage

• Model catalog — All foundation model IDs and CRIS inference profile IDs (pulled from live AWS APIs), provider reference, embedding model selection
• Converse API — Unified model invocation, streaming, tool use, multimodal inputs, prompt caching, extended thinking/reasoning
• Agents — Action groups (function definitions, OpenAPI, return control), Lambda handlers, code interpreter, KB association
• Knowledge Bases (RAG) — Vector stores (OpenSearch Serverless, Aurora, S3 Vectors), data sources, chunking strategies, retrieve and generate
• Guardrails — Content filters, PII protection, topic denial, word blocking, contextual grounding checks
• Model customization — Supervised fine-tuning, reinforcement fine-tuning, distillation, custom model import
• Prompt management and Flows — Reusable versioned prompts with variables, multi-step AI workflow orchestration

MCP Servers

• awslabs.bedrock-kb-retrieval-mcp-server — Knowledge Base querying with reranking
• awslabs.aws-bedrock-custom-model-import-mcp-server — Custom model lifecycle management

Note: Deliberately excludes amazon-bedrock-agentcore-mcp-server as it already has its own aws-agentcore power.

Why

Bedrock has a broad API surface across multiple boto3 clients (bedrock, bedrock-runtime, bedrock-agent, bedrock-agent-runtime). Without explicit steering, AI agents commonly:

• Use invoke_model() with model-specific JSON payloads instead of the Converse API
• Use single-region model IDs instead of CRIS inference profiles (lower throughput)
• Mix up build-time vs runtime clients
• Use outdated model IDs

The always-on guardrails table in POWER.md prevents these mistakes regardless of which steering file is loaded.
