Semgrep identified an issue in your code:
Prefer to use RequestFetcher's fetch function (#server-common/utils/requestFetcher.ts) instead of another library's fetch function. This is because RequestFetcher's fetch function has some built-in SSRF prevention mechanisms that other third-party fetch functions do not.

To resolve this comment:

✨ Commit Assistant Fix Suggestion

1. Import RequestFetcher from #server-common/utils/requestFetcher.
2. Create an instance of RequestFetcher before making your HTTP request. For example: const fetcher = new RequestFetcher();
3. Replace the direct fetch(url, ...) call with fetcher.fetch(url, ...) and use the same parameters.
4. Do the same for any retry/follow-up requests in this function.
5. Destroy the RequestFetcher instance after you are finished, using fetcher.destroy();.

Using RequestFetcher helps protect against SSRF vulnerabilities by enforcing additional security checks.

To resolve this comment:

✨ Commit Assistant Fix Suggestion

1. Remove any usage of the fetch function (or any other third-party HTTP request libraries) in this module.
2. Import the RequestFetcher utility from #server-common/utils/requestFetcher.ts if it's not already imported: import { RequestFetcher } from "#server-common/utils/requestFetcher";.
3. Create an instance of RequestFetcher at the top of the file or where appropriate: const fetcher = new RequestFetcher();
4. Replace your calls to fetch(url, { ... }) with fetcher.fetch(url, { ... }), preserving the same parameters and options.
5. If fetcher.fetch expects parameters in a different shape than the standard fetch API, update the options accordingly to match RequestFetcher's interface.

Alternatively, if you need to handle JSON responses and RequestFetcher provides a fetchJSON method, use fetcher.fetchJSON(url, {}, options) instead.

RequestFetcher automatically includes protections to help prevent Server-Side Request Forgery (SSRF) attacks.

Pull Request Summary: Complete GET Endpoint Coverage & Operations Structure Reorganization

🎯 Overview

This PR delivers complete GET endpoint coverage for the Vanta MCP Server, implementing comprehensive access to all major Vanta API resources, along with a systematic reorganization of the operations structure for enhanced maintainability and developer experience.

📊 Scale of Implementation

Massive Expansion of Operations Coverage

• 17 total operations files (up from original 4-5)
• 66 comprehensive evaluation test cases covering all implemented functionality
• 50+ individual tools implemented across all resource types

New Operations Files Created

• documents.ts - Document management and file handling (6 tools)
• policies.ts - Organizational policy management (2 tools)
• discovered-vendors.ts - Automated vendor discovery (2 tools)
• groups.ts - Organizational structure management (3 tools)
• people.ts - People and identity management (2 tools)
• vulnerabilities.ts - Vulnerability tracking (2 tools)
• vulnerability-remediations.ts - Remediation management (1 tool)
• vulnerable-assets.ts - Asset vulnerability tracking (2 tools)
• monitored-computers.ts - Endpoint monitoring (2 tools)
• vendor-risk-attributes.ts - Risk assessment criteria (1 tool)
• trust-centers.ts - Customer-facing compliance portals (24 tools)

Enhanced Existing Operations

• controls.ts - Added library controls, documents, and individual control retrieval
• frameworks.ts - Added individual framework retrieval
• risks.ts - Added individual risk scenario retrieval
• integrations.ts - Added complete resource management (6 tools total)
• vendors.ts - Added comprehensive vendor management (7 tools total)

🏗️ Major Technical Achievements

1. Complete API Coverage Implementation

• Documents: Full document lifecycle including intelligent file download with MIME type handling
• Trust Centers: Comprehensive customer portal management (24 endpoints)
• Vulnerability Management: Complete vulnerability tracking and remediation workflow
• Identity & Access: Full people and group management
• Vendor Risk: Complete vendor lifecycle from discovery to risk assessment
• Infrastructure: Complete integration and resource monitoring

2. DRY Architecture Refactoring

• Schema Factory Functions: createPaginationSchema(), createIdSchema(), createFilterSchema()
• Request Handler Utilities: makePaginatedGetRequest(), makeGetByIdRequest(), makeSimpleGetRequest()
• Response Processing: Standardized handleApiResponse(), createSuccessResponse(), createErrorResponse()
• URL Construction: buildUrl() with parameter handling
• Authentication: Centralized makeAuthenticatedRequest()

3. RESTful Naming Convention

• Adopted REST conventions: list_* for collections, get_* for individual resources
• Updated all tools: get_controls → list_controls, get_control_by_id → get_control
• Consistent naming: Input schemas, tool names, and function names all aligned

4. Automated Tool Registry System

• Zero-maintenance registration: New tools automatically discovered and registered
• Eliminated boilerplate: Reduced index.ts from 721 lines to 41 lines
• Type-safe registration: Full TypeScript support throughout the registry

5. Operations Structure Reorganization

• Created operations/common/ subdirectory for shared infrastructure
• Clean separation: Business logic files vs. infrastructure files
• Enhanced readability: Much cleaner operations directory listing
• Updated import patterns: Universal application of "./common/imports.js"

📁 Before & After Structure

Before - Limited Coverage:

Tool consolidation performed using a systematic approach to consolidate related tools while preserving functionality and improving usability:

Consolidation Examples

Document Operations (5→3 tools):

// Before: 5 separate tools
list_document_controls, list_document_links, list_document_uploads, documents, download_document_file

// After: 3 consolidated tools
documents (main listing + get by ID)
document_resources (consolidates 3 resource types with routing)
download_document_file (kept separate - file operations)

Integration Operations (5→2 tools):

// Before: 5 separate tools
integrations, list_integration_resource_kinds, get_integration_resource_kind_details,
list_integration_resources, get_integration_resource

// After: 2 consolidated tools
integrations (main listing + get by ID)
integration_resources (consolidates 4 operations with operation parameter)

Vendor Operations (6→4 tools):

// Before: 6 separate tools
vendors, list_vendor_documents, list_vendor_findings, list_vendor_security_reviews,
get_vendor_security_review, list_vendor_security_review_documents

// After: 4 consolidated tools
vendors (main listing + get by ID)
vendor_compliance (consolidates 3 compliance types)
get_vendor_security_review (kept separate - specific operation)
list_vendor_security_review_documents (kept separate - document operation)

Discovery Operations (4→1 tool):

// Before: 4 separate tools
list_discovered_vendors, list_discovered_vendor_accounts,
list_vendor_risk_attributes, list_vulnerability_remediations

// After: 1 consolidated tool
compliance_discovery (consolidates all discovery types)

Summary

• hard-coded enabledToolNames allowlist in src/config.ts and documented the limited tool surface; registration now skips everything not on that list
• added filtering inputs (statusFilter, frameworkFilter, integrationFilter) to the tests operation so list queries can be scoped without breaking single-test lookups; similar additions for other tools for the most common or useful filtering parameters
• refreshed the README tables to only advertise the active tools

Tool Allowlist

src/config.ts now restricts registration to this set: tests, list_test_entities, people, documents, document_resources, integrations, integration_resources, controls, list_control_tests, list_control_documents, vulnerabilities, frameworks, list_framework_controls, risks.

Testing

• ✅ tested using the MCP testing tool
• ⚠️ limited testing performed using Claude
• ⛔ unable to run automated tests in eval due to not having an OpenAI token with sufficient calls available
