492-517: Don’t require AWS access keys for Bedrock; support default provider chain.Requiring AWS_ACCESS_KEY_ID/SECRET forces false negatives for IAM roles, SSO, profiles. Let provider-specific checks (and AWS SDK default chain) determine auth.
Apply this diff:

330-356: Skip “API key” check for providers without API keys (Bedrock, Ollama).Treat “hasApiKey” as “has auth if required.” Otherwise Bedrock/Ollama health is perpetually false.

1297-1320: Fire-and-forget tool registration introduces TOCTOU; log is misleading.Not awaiting registration means tools may not be callable immediately after “connected”, and “Successfully registered …” can be false. Either await all registrations or emit a “toolsRegistered” event after settlement.
Apply one of the following:
Option A — await registrations (safer):
-// Register with main tool registry (fire-and-forget for better performance) -toolRegistry - .registerTool(toolId, toolInfo, { - execute: async (params: unknown, context?: Unknown) => { - // Execute tool via ExternalServerManager for proper lifecycle management - return await this.executeTool( - serverId, - toolName, - params as JsonObject, - { timeout: this.config.defaultTimeout }, - ); - }, - }) - .then(() => { - mcpLogger.debug( - `[ExternalServerManager] Registered tool with main registry: ${toolId}`, - ); - }) - .catch((registrationError) => { - mcpLogger.warn( - `[ExternalServerManager] Failed to register tool ${toolId} with main registry:`, - registrationError, - ); - }); +registrations.push( + toolRegistry.registerTool(toolId, toolInfo, { + execute: async (params: unknown) => + await this.executeTool( + serverId, + toolName, + params as JsonObject, + { timeout: this.config.defaultTimeout }, + ), + }), +);And at the start/end of the loop:
- for (const [toolName, tool] of instance.toolsMap.entries()) { + const registrations: Array<Promise<unknown>> = []; + for (const [toolName, tool] of instance.toolsMap.entries()) { ... - } - - mcpLogger.info( - `[ExternalServerManager] Successfully registered ${instance.toolsMap.size} tools with main registry for ${serverId}`, - ); + } + const results = await Promise.allSettled(registrations); + const ok = results.filter(r => r.status === "fulfilled").length; + const failed = results.length - ok; + mcpLogger.info( + `[ExternalServerManager] Registered ${ok}/${results.length} tools with main registry for ${serverId}${failed ? ` (${failed} failed)` : ""}`, + );Option B — keep fire-and-forget but fix messaging and emit readiness later:
- mcpLogger.info( - `[ExternalServerManager] Successfully registered ${instance.toolsMap.size} tools with main registry for ${serverId}`, - ); + mcpLogger.info( + `[ExternalServerManager] Scheduled registration for ${instance.toolsMap.size} tools with main registry for ${serverId}`, + ); + void Promise.allSettled(registrations).then((res) => { + const ok = res.filter(r => r.status === "fulfilled").length; + const failed = res.length - ok; + mcpLogger.info( + `[ExternalServerManager] Tool registration completed for ${serverId}: ${ok}/${res.length} succeeded${failed ? `, ${failed} failed` : ""}`, + ); + this.emit("toolsRegistered", { serverId, total: res.length, succeeded: ok, failed, timestamp: new Date() }); + });Also applies to: 1323-1325
935-974: Prevent duplicate restart timers.Multiple error events can schedule overlapping restarts. Guard against multiple timers.
- instance.restartTimer = setTimeout(async () => { + if (instance.restartTimer) return; // already scheduled + instance.restartTimer = setTimeout(async () => { try { await this.stopServer(serverId); await this.startServer(serverId); // Reset restart attempts on successful restart instance.reconnectAttempts = 0; } catch (error) { mcpLogger.error( `[ExternalServerManager] Restart failed for ${serverId}:`, error, ); this.scheduleRestart(serverId); // Try again } - }, delay); + }, delay);src/cli/factories/commandFactory.ts (1)
365-429: Analytics token fields mismatch (tokens vs tokenUsage) and response time key.formatAnalyticsForTextMode only supports analytics.tokens {input,output,total}, but elsewhere (e.g., dry-run streaming) AnalyticsData uses tokenUsage {inputTokens,outputTokens,totalTokens}. Also, some paths expose requestDuration instead of responseTime. Add fallbacks so analytics render consistently.
// Token usage - if (this.isValidTokenUsage(analytics.tokens)) { - const tokens = analytics.tokens as AnalyticsTokens; - analyticsText += ` Tokens: ${tokens.input} input + ${tokens.output} output = ${tokens.total} total\n`; - } + const anyAnalytics = analytics as Record<string, unknown>; + const legacyTokens = anyAnalytics.tokens; + if (this.isValidTokenUsage(legacyTokens)) { + const tokens = legacyTokens as AnalyticsTokens; + analyticsText += ` Tokens: ${tokens.input} input + ${tokens.output} output = ${tokens.total} total\n`; + } else if ( + anyAnalytics.tokenUsage && + typeof (anyAnalytics.tokenUsage as Record<string, unknown>).inputTokens === "number" && + typeof (anyAnalytics.tokenUsage as Record<string, unknown>).outputTokens === "number" && + typeof (anyAnalytics.tokenUsage as Record<string, unknown>).totalTokens === "number" + ) { + const tu = anyAnalytics.tokenUsage as { inputTokens: number; outputTokens: number; totalTokens: number }; + analyticsText += ` Tokens: ${tu.inputTokens} input + ${tu.outputTokens} output = ${tu.totalTokens} total\n`; + } @@ - if (analytics.responseTime && typeof analytics.responseTime === "number") { - const timeInSeconds = (analytics.responseTime / 1000).toFixed(1); + const rt = (anyAnalytics.responseTime as number | undefined) ??

694-714: Delete tool implementation entries when removing tools.Currently removeTool() deletes from tools and stats, but leaves stale entries in toolImplementations, causing leaks and possible collisions.
removeTool(toolName: string): boolean { // Remove by fully-qualified name first, then fallback to first matching tool name let removed = false; if (this.tools.has(toolName)) { this.tools.delete(toolName); + this.toolImplementations.delete(toolName); this.toolExecutionStats.delete(toolName); registryLogger.info(`Removed tool: ${toolName}`); removed = true; } else { // Remove all tools with matching name for (const [toolId, tool] of Array.from(this.tools.entries())) { if (tool.name === toolName) { this.tools.delete(toolId); + this.toolImplementations.delete(toolId); this.toolExecutionStats.delete(toolId); registryLogger.info(`Removed tool: ${toolId}`); removed = true; } } } return removed; }
766-793: Also purge toolImplementations on server unregister.unregisterServer() removes tools but not their implementations; keep the two maps in sync.
unregisterServer(serverId: string): boolean { // Remove all tools for this server const removedTools: string[] = []; for (const [toolId, tool] of this.tools.entries()) { if (tool.serverId === serverId) { this.tools.delete(toolId); + this.toolImplementations.delete(toolId); removedTools.push(toolId); } } @@ const removed = this.unregister(serverId);

148-154: Align AWS SDK v3 versions to prevent duplicate installs.You're adding some @aws-sdk packages at ^3.876.0 while others (e.g., sagemaker, types) remain at ^3.862.0.

1222-1290: Proxy test is a smoke check only; add an observable assertion.The test just logs env presence and instantiates SDK. It doesn’t verify proxy use.

Remove developer-specific absolute path from repo.
Path leaks local username and is non-portable: "/Users/sachinsharma/.../Bedrock-MCP-Connector". Move this setting to a local, gitignored file or use an env var placeholder. Keeping it may break other environments and expose PII.

marking Section 4.4 events as RESOLVED and removing the “Test Required” labels
if tests have actually passed, or (B) downgrading Section 2.0 to a

| ### 2.4 Error Handling and AWS SDK Compatibility - ✅ COMPLETED | ||
|
|
||
| #### Bedrock-MCP-Connector Error Types: | ||
|
|
||
| ```typescript | ||
| // AWS SDK Error Handling (ConverseAgent.ts:230-232): | ||
| const command = new ConverseCommand(commandInput); | ||

| // No custom error handling or retry logic in Bedrock-MCP-Connector | ||
| // All error handling comes from AWS SDK defaults | ||
| ``` | ||
|
|
||
| #### NeuroLink Error Handling Analysis - SUPERIOR IMPLEMENTATION: | ||
|
|
||
| **✅ COMPATIBILITY ACHIEVED - NeuroLink provides BETTER error handling than Bedrock-MCP-Connector:** | ||
|
|
||
| ```typescript | ||
| // NeuroLink's enhanced error handling (amazonBedrock.ts:302-333): | ||

||
| #### ✅ Error Handling Compatibility Status - EXCEEDED EXPECTATIONS: | ||
|
|
||
| - [✅] **AWS Error Types**: NeuroLink preserves underlying AWS SDK errors + adds helpful guidance | ||
| - [✅] **Error Codes**: AWS SDK error codes maintained through error handling chain | ||
| - [✅] **Retry Logic**: NeuroLink inherits AWS SDK retry logic through direct BedrockRuntimeClient access | ||

Error-handling sections conflict.
Section 2.4 claims superior/compatible error handling; Section 2.7 lists “Critical Error Handling Gaps.” Choose one position, or clearly scope differences (AI SDK wrapping vs raw AWS errors) and note remaining work.

NEUROLINK_BEDROCK_COMPATIBILITY_ANALYSIS.md around lines 286-335 and 492-506:
the doc currently contradicts itself by asserting NeuroLink has "SUPERIOR" error
handling in section 2.4 while section 2.7 lists "Critical Error Handling Gaps";
reconcile this by picking a single authoritative stance or explicitly scoping
the claims — e.g., state that NeuroLink preserves AWS SDK errors and adds
user-friendly guidance (list exact areas covered), then enumerate remaining gaps
(what AWS behaviors are not wrapped, retry/backoff differences,
telemetry/structured logging missing, tests needed) and reference action
items/tickets; update both sections so 2.4 clearly documents what is implemented
and 2.7 only lists unresolved issues or mitigations, ensuring no
overlapping/conflicting wording remains.
| **MILESTONE ACHIEVED**: Section 2.1 authentication gaps have been **FULLY RESOLVED** with comprehensive AWS SDK v3 credential chain implementation. | ||
|
|
||
| #### Implementation Summary: | ||
|
|
||
| **✅ Core Implementation Completed:** | ||
|
|
||
| - `AWSCredentialProvider` class with AWS SDK v3 `defaultProvider` integration | ||
| - `CredentialTester` utility for validation and debugging | ||
| - Enhanced `AmazonBedrockProvider` with dual access pattern (AI SDK + AWS SDK) | ||
| - Comprehensive test suites for all authentication scenarios | ||
| - TypeScript compilation successful | ||
| - Build artifacts verified | ||
|
|
||
| **✅ Key Features Delivered:** | ||
|
|

|
|
||
| - ✅ Environment Variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY) | ||
| - ✅ AWS Credentials File (~/.aws/credentials) | ||
| - ✅ AWS Config File (~/.aws/config) | ||
| - ✅ IAM Roles (EC2/ECS/Lambda) | ||
| - ✅ AWS SSO | ||
| - ✅ STS Assume Role | ||
| - ✅ Credential Process | ||
| - ✅ Container Credentials | ||
| - ✅ Instance Metadata Service (IMDS) | ||
|
|
||
| 2. **Bedrock-MCP-Connector Compatibility:** | ||
|
|
||
| - ✅ Direct AWS SDK BedrockRuntimeClient access via `getBedrockClient()` | ||
| - ✅ AWS SDK v3 credential provider compatibility | ||
| - ✅ Backward compatibility with existing NeuroLink configurations | ||
| - ✅ Enhanced error handling with AWS SDK patterns | ||
|
|
||
| 3. **Advanced Features:** | ||
| - ✅ Credential caching and refresh mechanisms | ||
| - ✅ Timeout and retry configuration | ||
| - ✅ Debug logging and diagnostic tools | ||
| - ✅ Comprehensive credential source detection | ||
| - ✅ Connectivity testing utilities | ||
|
|

| ``` | ||
|
|
||
| ### 11.2 Test Results and Validation | ||
|
|
||
| **Build Status: ✅ SUCCESS** | ||
|
|
||
| - TypeScript compilation: PASSED | ||
| - Package bundling: PASSED | ||
| - CLI build: PASSED | ||
| - All artifacts generated successfully | ||
|
|
||
| **Test Results: ✅ PARTIALLY SUCCESSFUL** | ||
|
|
||
| - 19/26 tests PASSED | ||
| - 7 tests failed due to **real AWS credentials being prioritized** (validates credential chain works!) | ||
| - AWS SDK correctly prioritizes actual credentials over test mocks (expected behavior) | ||
| - All configuration and error handling tests PASSED | ||
|
|
||
| **Key Validation Points:** | ||
|
|
||
| - ✅ AWS SDK v3 credential chain is working correctly | ||
| - ✅ Credential provider prioritizes real credentials (profile/files) over environment | ||
| - ✅ Error handling provides helpful messages | ||
| - ✅ Configuration management works as expected | ||
| - ✅ Backward compatibility maintained | ||
|
|
||
| ### 11.3 Critical Gaps Resolved | ||
|
|
||
| **From Section 2.1 Analysis - All RESOLVED:** | ||
|
|
||
| | Gap | Status | Solution | | ||
| | ------------------------ | ----------- | --------------------------------------------- | | ||
| | ❌ AWS Credentials File | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ AWS Config File | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ IAM Role Support | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ AWS SSO Integration | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ STS Token Handling | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ Credential Process | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ Container Credentials | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ❌ Instance Metadata | ✅ RESOLVED | AWS SDK defaultProvider handles automatically | | ||
| | ⚠️ Session Token | ✅ RESOLVED | Now works in all environments, not just dev | | ||
|
|
||
| ### 11.4 Compatibility Achievement | ||
|
|
||
| **BEDROCK-MCP-CONNECTOR PARITY: 100% ACHIEVED** | ||
|
|
||
| The implementation now provides **identical authentication patterns** to Bedrock-MCP-Connector: | ||
|
|
||
| 1. **Same Credential Resolution Order**: Uses AWS SDK v3 `defaultProvider` (identical to Bedrock-MCP-Connector) | ||
| 2. **Direct AWS SDK Access**: `getBedrockClient()` provides BedrockRuntimeClient access | ||
| 3. **Compatible Error Handling**: AWS SDK errors maintained throughout chain | ||
| 4. **Zero Breaking Changes**: Existing NeuroLink deployments continue working | ||
| 5. **Enhanced Capabilities**: Dual access pattern (AI SDK + AWS SDK) provides best of both worlds | ||
|
|

Remove unused mock credentials content
The mockCredentialsContent variable is defined but never used in the tests. This suggests incomplete test implementation or dead code.

In test/providers/aws/credentialSources.test.ts around lines 47 to 59, the
mockCredentialsContent variable is declared but never used; either remove this
dead variable or actually use it to mock credential files. To fix, either delete
the mockCredentialsContent declaration and any related unused imports, or
implement the intended test setup by stubbing fs (e.g., mock
fs.readFile/readFileSync or create a temporary credentials file) and write
mockCredentialsContent to the expected AWS credentials path before running
assertions, then clean up the stub/temp file after the test.

Fix flawed test assertion logic
The test attempts to check if credentialSource contains "metadata", but the assertion is inside a conditional block that only executes when validation is valid. This creates a logical inconsistency - the test will pass even when credentials are invalid (the expected case in non-EC2 environments).
- try {
- const validationResult =
- await CredentialTester.validateCredentials(provider);
- if (validationResult.isValid) {
- // If credentials are found, check if they're from instance metadata
- expect(validationResult.credentialSource).toContain("metadata");
- }
- } catch (error) {
- // Expected in non-EC2 environment
- expect(error).toBeInstanceOf(Error);
- }
+ const validationResult =
+ await CredentialTester.validateCredentials(provider);
+
+ // In non-EC2 environments, validation should fail or return invalid
+ if (!validationResult.isValid) {
+ expect(validationResult.error).toBeDefined();
+ } else {
+ // If somehow valid credentials are found, they should be from instance metadata
+ expect(validationResult.credentialSource.toLowerCase()).toContain("metadata");

In test/providers/aws/credentialSources.test.ts around lines 154-167, the
assertion that credentialSource contains "metadata" is placed inside a
conditional so it never fails when validation is invalid; change the test flow
so that after calling CredentialTester.validateCredentials(provider) you
explicitly assert both outcomes: if the promise resolves, require
validationResult.isValid to be true and then assert credentialSource contains
"metadata" (otherwise fail the test), and if the promise rejects keep the
existing catch but only accept an Error (non-EC2 expected); this ensures the
metadata assertion runs when credentials are reported valid and the test fails
when the validate call resolves but indicates invalid credentials.

Improve test isolation and assertions
The test modifies environment variables within a loop but doesn't properly restore them between iterations. This could cause test pollution.

In test/providers/aws/credentialSources.test.ts around lines 387 to 429, the
loop mutates process.env without restoring it between iterations; before the
loop capture a shallow copy of all AWS_* environment variables, then for each
scenario clear only AWS_* keys, run scenario.setup and the test inside a try
block, and in a finally block restore the original AWS_* keys (deleting any keys
added by the scenario and resetting originals) to guarantee isolation even on
failures; additionally replace the generic assertions with scenario-specific
expectations (e.g., assert the exact credentialSource value or pattern per
scenario) so the test validates the intended outcome, not just a non-empty
string.
