MCP server for AWS Cloud Development Kit (CDK) best practices, infrastructure as code patterns, and security compliance with CDK Nag.
Connect Tmp Cdk to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for AWS Cloud Development Kit (CDK) best practices, infrastructure as code patterns, and security compliance with CDK Nag. The tmp cdk mcp server is what makes that connection.
aws-cdk on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
CDKGeneralGuidance — Get prescriptive advice for building AWS applications with CDKGetAwsSolutionsConstructPattern — Find vetted architecture patterns combining AWS servicesSearchGenAICDKConstructs — Discover GenAI CDK constructs by name or featuresGenerateBedrockAgentSchema — Create OpenAPI schemas for Bedrock Agent action groupsLambdaLayerDocumentationProvider — Access documentation for Lambda layers implementationExplainCDKNagRule — Get detailed guidance on CDK Nag security rulesCheckCDKNagSuppressions — Validate CDK Nag suppressions in your codeConfiguration is passed through the environment: FASTMCP_LOG_LEVEL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
uv from Astral or the GitHub README 2. Install Python using uv python install 3.10 3. Install AWS CDK CLI using npm install -g aws-cdk (Note: The MCP server itself doesn't use the CDK CLI directly, but it guides users through CDK application development that requires the CLI)Among the cloud and infrastructure options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Tmp Cdk's toolset — CDKGeneralGuidance, GetAwsSolutionsConstructPattern, SearchGenAICDKConstructs and 4 more — is a fair guide to whether it matches your workflow. It is maintained by AkM-2018; worth a glance at recent repository activity before you build anything load-bearing on it.
