[dharsj]

Summary

• Adds ContextIQ to partner-built/ — an MCP-native knowledge server that gives Cowork and Claude Desktop governed access to enterprise knowledge sources
• Returns cited answers scoped to user entitlements with audit-ready answer paths
• Deploys into the customer's AWS account via CloudFormation (Bedrock AgentCore, ECS, Bedrock Knowledge Bases, S3 Vectors)
• Includes stdio-to-HTTP MCP proxy for Cowork transport bridging with Cognito authentication
• Two skills: Governed Query (cited enterprise knowledge retrieval) and Source Discovery (entitlement-scoped source listing)

Hi @tobinsouth @bryan-anthropic — friendly ping on this PR. ContextIQ is live on AWS Marketplace and we have customers using the Cowork integration today. Happy to address any feedback on the plugin structure or content. Thanks!
