Integrate with Activity Log." +**Related Proposal**: `docs/proposals/004-security-attack-detection.md` (Phase 3) + +## Overview + +This feature adds automatic detection of sensitive data in MCP tool call arguments and responses. The focus is on **secrets and credentials** (API keys, private keys, tokens) and **sensitive file path access** (SSH keys, cloud credentials, environment files). Detection results are recorded in the Activity Log, enabling users to identify potential data exposure or exfiltration risks. + +**Design Principle**: Detection-only mode - no automatic blocking or redaction. Users gain visibility into sensitive data flows to make informed decisions. + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Detect Secrets in Tool Call Data (Priority: P1) + +A security-conscious user wants to know when API keys, tokens, or credentials pass through MCPProxy. When an AI agent accidentally exposes an AWS key or GitHub token in tool arguments or responses, the user should see this flagged in the Activity Log. + +**Why this priority**: Secrets are the highest-risk sensitive data. Leaked credentials can lead to account takeover, data breaches, and financial loss. This is the core security value. + +**Independent Test**: Execute a tool call with an AWS access key (AKIAIOSFODNN7EXAMPLE) in arguments, view Activity Log, verify detection indicator shows "aws_access_key" type. + +**Acceptance Scenarios**: + +1. **Given** a tool call contains `AKIAIOSFODNN7EXAMPLE` in arguments, **When** I view the Activity Log, **Then** I see a sensitive data indicator with "aws_access_key" detected +2. **Given** a tool response contains a GitHub PAT (`ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`), **When** I view activity details, **Then** I see "github_token" type with location "response" +3. **Given** a tool call contains `-----BEGIN RSA PRIVATE KEY-----`, **When** detection runs, **Then** "private_key" type is detected with severity "critical" +4. **Given** a tool call contains a Stripe key (`sk_live_` + 24 chars), **When** I view details, **Then** "stripe_key" is detected + +--- + +### User Story 2 - Detect Sensitive File Path Access (Priority: P1) + +A user wants to know when an AI agent attempts to read sensitive files like SSH private keys, AWS credentials, or environment files. This could indicate a compromised or malicious MCP server attempting data exfiltration. + +**Why this priority**: File path detection catches exfiltration attempts at the intent stage - before secrets are actually exposed. This is critical for detecting tool poisoning attacks. + +**Independent Test**: Execute a tool call with argument `{"path": "~/.ssh/id_rsa"}`, verify Activity Log shows "sensitive_file_path" detection with "ssh_private_key" category. + +**Acceptance Scenarios**: + +1. **Given** a tool argument contains `~/.ssh/id_rsa` (Linux/macOS) or `C:\Users\user\.ssh\id_rsa` (Windows), **When** detection runs, **Then** "sensitive_file_path" is detected with category "ssh" and severity "critical" +2. **Given** a tool argument contains `/home/user/.aws/credentials` (Linux) or `%USERPROFILE%\.aws\credentials` (Windows), **When** I view details, **Then** "aws_credentials_file" is detected +3. **Given** a tool argument contains `.env.production`, **When** detection runs, **Then** "env_file" is detected with severity "high" +4. **Given** a tool argument contains `/etc/shadow` (Linux), **When** detection runs, **Then** "system_password_file" is detected with severity "critical" +5. **Given** a tool argument contains `C:\Users\user\AppData\Roaming\npm\npmrc` (Windows), **When** detection runs, **Then** "auth_token_file" is detected + +--- + +### User Story 3 - View and Filter Detection Results (Priority: P1) + +A compliance officer needs to audit all tool calls that involved sensitive data. They want to filter the Activity Log to show only records where sensitive data was detected, with the ability to filter by detection type and severity. + +**Why this priority**: Filtering is essential for practical use at scale. Without it, users must manually scan all records, making security auditing impractical. + +**Independent Test**: Execute multiple tool calls (some with secrets, some without), filter Activity Log by "Sensitive Data: Yes" and severity "critical", verify only relevant records appear. + +**Acceptance Scenarios**: + +1. **Given** the Activity Log contains mixed records, **When** I filter by "Sensitive Data Detected", **Then** only records with detections are shown +2. **Given** I want to find API key exposures, **When** I filter by type "api_key", **Then** only records with API key detections appear +3. **Given** I want critical issues only, **When** I filter by severity "critical", **Then** only critical detections (private keys, cloud credentials) appear +4. **Given** I'm using CLI, **When** I run `mcpproxy activity list --sensitive-data --severity critical`, **Then** filtered results are returned + +--- + +### User Story 4 - CLI Sensitive Data Visibility (Priority: P2) + +A developer using MCPProxy via CLI wants to see sensitive data detection results when reviewing activity. The CLI should show detection status in list output and full details in the show command. + +**Why this priority**: CLI is a primary interface for developers and automation. Enables scripting and integration with security tools. + +**Independent Test**: Run `mcpproxy activity list` after sensitive data detection, verify indicator column. Run `mcpproxy activity show `, verify full detection details. + +**Acceptance Scenarios**: + +1. **Given** activity records with detections exist, **When** I run `mcpproxy activity list`, **Then** I see a "SENSITIVE" indicator column +2. **Given** an activity record with detected secrets, **When** I run `mcpproxy activity show `, **Then** I see detection types, severities, and locations +3. **Given** I want JSON for automation, **When** I run `mcpproxy activity list --sensitive-data -o json`, **Then** I get structured detection data + +--- + +### User Story 5 - Configure Custom Detection Patterns (Priority: P3) + +An enterprise user has organization-specific sensitive data formats (e.g., internal API key format `ACME-KEY-xxxxxxxx`, employee IDs) that should be detected. They want to add custom regex patterns. + +**Why this priority**: Custom patterns extend the system to organization-specific needs but are not required for core functionality. Most users benefit from built-in patterns alone. + +**Independent Test**: Add custom pattern via configuration, execute tool call with matching data, verify custom pattern detected in Activity Log. + +**Acceptance Scenarios**: + +1. **Given** I configure `{"name": "acme_api_key", "regex": "ACME-KEY-[a-f0-9]{32}", "severity": "high"}`, **When** a tool call contains "ACME-KEY-abc123...", **Then** it is detected as "acme_api_key" +2. **Given** I add sensitive keywords `["internal-only", "confidential"]`, **When** those words appear in tool data, **Then** they are flagged +3. **Given** an invalid regex pattern, **When** MCPProxy starts, **Then** I see a warning and the invalid pattern is skipped + +--- + +### User Story 6 - Detect Credit Card Numbers (Priority: P3) + +A user working with payment-related tools wants to ensure credit card numbers are flagged if they appear in tool call data, as this could indicate PCI compliance issues. + +**Why this priority**: Credit cards are a special PII category with regulatory implications (PCI-DSS). Lower priority than secrets because legitimate payment tools may handle card data intentionally. + +**Independent Test**: Execute tool call with test card number `4111111111111111`, verify detection with Luhn validation (valid card detected, random 16-digit numbers ignored). + +**Acceptance Scenarios**: + +1. **Given** a tool call contains `4111111111111111`, **When** detection runs, **Then** "credit_card" is detected (passes Luhn validation) +2. **Given** a tool call contains `1234567890123456` (invalid Luhn), **When** detection runs, **Then** it is NOT flagged as credit card +3. **Given** a tool call contains `4111-1111-1111-1111` (with dashes), **When** detection runs, **Then** "credit_card" is still detected + +--- + +### Edge Cases + +- What happens when detection encounters very large payloads (>1MB)? Detection applies to first 1MB with truncation flag. +- How are false positives handled? Users view detection details to assess; no automatic action taken. +- What if a secret pattern matches example/test values?
