All gateway targets are now behind-gateway only. The mcp-runtime exposure mode was disabled and never used by customers. - Remove ExposureMode type, EXPOSURE_MODE_OPTIONS, --exposure and --agents CLI flags - Simplify wizard flow: name → source → language → gateway → host → confirm - Remove mcp-runtime code paths from create-mcp, remove-gateway-target, McpGuidedEditor - Remove existingAgents prop chain (only used for mcp-runtime agent selection) - Clean up unused imports (ViewMode, AgentCoreMcpRuntimeTool, WizardMultiSelect)
- Remove mcp-runtime validation tests and fixtures - Remove mcp-runtime integration tests (add and remove) - Simplify gateway target test fixtures to behind-gateway only

TUI uses React state for proper rendering. API errors are non-blocking — deploy succeeds regardless of status query result. * refactor: remove gateway bind flow from add gateway TUI (#431) Gateways are project-level in Phase 1 — all agents get all gateways automatically via CDK env vars. The bind-agent-to-gateway flow was pre-Phase 1 code that is no longer needed. Add gateway now goes straight to the create wizard. * fix: prettier formatting for gateway-status.ts (#449) * feat: add gateway auth and multi-gateway support to agent templates (#427) * feat: add gateway auth support to agent templates Add SigV4 authentication to MCP client templates so agents can authenticate with AWS_IAM gateways. Each framework's client.py uses Handlebars conditionals to include auth when gateways exist. SigV4HTTPXAuth class signs HTTP requests using botocore SigV4Auth, passed to the MCP client via httpx.AsyncClient. Templates read gateway URLs from AGENTCORE_GATEWAY_{NAME}_URL env vars and handle missing vars gracefully (warn, don't crash). Updated all 5 frameworks: Strands, LangChain, OpenAI Agents, Google ADK, AutoGen. Schema mapper reads mcp.json to populate gateway config for template rendering. All gateways are auto- included when creating an agent. * feat: add multi-gateway support and fix template rendering Replace single-gateway [0] indexing with {{#each gatewayProviders}} loops. Each gateway gets its own client function (Strands) or entry in the servers dict (LangChain/OpenAI/AutoGen/ADK). Add snakeCase Handlebars helper for gateway function names. Add gatewayAuthTypes array for conditional SigV4 imports. Fix @index parse error by using plain variable names. * fix: update main.py files with gateway conditional imports All 5 framework main.py files now use Handlebars conditionals to import the correct MCP client function based on hasGateway flag. Fix snakeCase helper to handle all special characters. * style: fix formatting * refactor: use mcp-proxy-for-aws for gateway auth, remove AutoGen gateway support Replace custom SigV4HTTPXAuth class with official mcp-proxy-for-aws package: - Strands: aws_iam_streamablehttp_client factory pattern - LangChain: SigV4HTTPXAuth via auth param in MultiServerMCPClient config - OpenAI Agents: SigV4HTTPXAuth via httpx_client_factory param - Google ADK: SigV4HTTPXAuth via httpx_client_factory in StreamableHTTPConnectionParams Revert AutoGen to original upstream — SDK doesn't support custom httpx auth (no httpx_client_factory param). * fix: pass AWS region to aws_iam_streamablehttp_client in Strands template * refactor: remove dead agent binding step from add gateway wizard (#456) * feat: wire existing-endpoint flow for gateway targets (#455) * feat: wire existing-endpoint flow for gateway targets * test: add routing and validation tests for existing-endpoint flow * refactor: remove source/language/host steps, existing-endpoint is the only flow * fix: CDK template types and credential ARN passthrough for gateway deploy (#432) * fix: correct CDK template type names and prop names The CDK stack template used McpSpec (doesn't exist) instead of AgentCoreMcpSpec, and passed wrong prop names to AgentCoreMcp: - spec → mcpSpec - application → agentCoreApplication - Added missing projectName prop * fix: collect API key credential ARNs and write to deployed state before CDK synth API key credential providers were created during deploy but their ARNs were not stored in deployed state, causing CDK to fail with 'Credential not found in deployed state' for gateway targets with API key auth. - Return credentialProviderArn from create/update API key providers - Unify API key and OAuth credential ARNs into single deployed state map - Move credential setup before CDK synth so template can read ARNs - Write partial deployed state with credentials before synth * fix: pass credential ARNs from deployed state to CDK gateway construct CDK template now reads deployed-state.json and extracts credential provider ARNs per target, passing them to AgentCoreMcp so gateway targets can reference outbound auth credentials. * fix: reorder TUI preflight to create credentials before CDK synth * fix: fetch OAuth credential ARN via Get after create/update * fix: handle Mcp prefix in gateway output key parsing * fix: bump CDK version to 2.239.0 in project template * fix: lint errors in deploy actions and preflight hook * feat: set gateway env vars in agentcore dev for local testing (#428) Read deployed-state.json for gateway URLs and mcp.json for auth types, then set AGENTCORE_GATEWAY_{NAME}_URL and AGENTCORE_GATEWAY_{NAME}_AUTH_TYPE env vars when running agentcore dev locally. - New gateway-env.ts helper iterates all deployment targets - Integrated in both CLI dev command and TUI dev hook - .env.local values take precedence over gateway env vars - Graceful fallback when no deployed state exists - Fixed parseGatewayOutputs to parse Id, Arn, and Url outputs separately - Added gatewayUrl field to deployed-state schema (optional, backward compat) * fix: prettier formatting for upstream files (#461) * refactor: remove dead bind flow and rename MCP Tool to Gateway Target (#459) * refactor: remove mode selection and bind flow from gateway target wizard * fix: rename 'MCP Tool' to 'Gateway Target' in UI labels, CLI output, and comments * fix: update CDK asset snapshot for cdk/bin/cdk.ts * fix: prettier formatting for AddGatewayTargetFlow.tsx * feat: add outbound auth wizard step with inline credential creation (#417) * fix: require gateway when creating a gateway target (#469) * fix: require gateway when creating a gateway target A gateway target must always be attached to a gateway. Previously it was possible to create unassigned targets via "Skip for now" in the TUI or by omitting --gateway in non-interactive mode. - Validation now requires --gateway and verifies the gateway exists - TUI removes the "Skip for now" option from gateway selection - createExternalGatewayTarget rejects missing gateway at operations layer - Updated tests to cover all new validation paths * style: fix prettier formatting * fix: correct gateway success message to reference gateway-target command (#468) * feat: add OAuth credential type to add identity TUI wizard (#464) * feat: add OAuth credential type to add identity TUI wizard * fix: add OIDC well-known suffix validation to identity TUI discovery URL * refactor: reuse identity screen for OAuth credential creation in gateway target flow * fix: correct deploy step ordering and credential count display * fix: allow identity creation without existing agents * fix: rename MCP gateway references to gateway in UI text * fix: add missing newline to identity types * feat: implement inbound auth (#467) * feat: extend JWT wizard with allowedScopes and agent OAuth credential inputs * feat: auto-create managed OAuth credential for CUSTOM_JWT gateway * feat: add CLI flags for CUSTOM_JWT agent OAuth credentials * feat: add CUSTOM_JWT Bearer token auth to agent templates (Strands, LangChain, OpenAI, Google ADK) * feat: protect managed credentials from accidental deletion * test: add tests for CUSTOM_JWT CLI validation and managed credential protection * fix: resolve httpx import collision between AWS_IAM and CUSTOM_JWT templates * fix: use placeholder instead of initialValue for gateway discovery URL * feat: wire CUSTOM_JWT inbound auth through AgentCore identity system * fix: prettier formatting and remove redundant condition * fix: sanitize OAuth error to prevent clear-text logging of sensitive data --------- Co-authored-by: Tejas Kashinath <42380254+tejaskash@users.noreply.github.com>

Description
Remove the
exposure/mcp-runtimemode from theadd gateway-targetcommand. All gateway targets are now behind-gateway only.The exposure field previously allowed two modes:
mcp-runtime(standalone MCP tools attached directly to agents) andbehind-gateway(targets routed through a gateway). Themcp-runtimemode was disabled and never exposed to users. This PR removes it entirely, simplifying the codebase and the wizard flow.Changes:
EXPOSURE_MODE_OPTIONSconstant,--exposureand--agentsCLI flagsname → source → language → gateway → host → confirm (create-new) and name → source → endpoint → gateway → confirm (existing-endpoint)Related Issue
Part of the MCP Gateway Phase 1 integration (gateway-integration branch). Cleanup identified during Batch 3 test writing.
