"Using agents in VSCode to reference library documentation during programming" matching MCP servers:

VS Code Extension & Model Context Protocol Suite Orchestrator for Cursor, Claude Desktop, and VS Code IDEs.

Secure MCP server that enforces allowlist-based policies, read-only access, input validation, and human-in-the-loop for sensitive actions, enabling safe vulnerability analysis.

Enables AI agents to discover each other and communicate through cryptographically verified messaging and secure inbox management via the Agents Registry. It provides tools for Ed25519-based identity authentication, message signing, and agent discovery across domains.

An MCP server that sends plain-text Gmail messages only to a predefined allowlist, using generated recipient IDs instead of email addresses to enforce security.

Validates AGENTS.md files against the cross-vendor coding-agent spec, detecting security smells and consistency issues.

Enables AI assistants to search and retrieve information from the REMnux malware analysis toolkit documentation, allowing users to ask questions about reverse-engineering tools and get accurate, up-to-date answers from the live documentation.

Enables authorized web/API security analysis as a stateful, multi-stage workflow with persistent session state, human-controlled validation, candidate versus confirmed finding tracking, and stop conditions.

Enables autonomous agents and MCP-compatible clients to enforce policy-approved actions using risk tiers, reversible checkpoints, and token approval bounds.

Blocks AI coding assistants from installing non-existent packages and accessing non-existent files.

Provides 14 MCP tools for AI agent infrastructure, enabling knowledge base queries, skill search, handoffs, blueprint validation, trust scoring, identity verification, SLA validation, and compliance checks.

Enables AI assistants to search and retrieve security, privacy, and AI-governance controls from multiple compliance frameworks (e.g., NIST, HIPAA, OWASP) with cross-references, providing authoritative cited control text.

Enables a sandboxed Claude Code session to see editor selections, review proposed edits as VS Code diffs, and read workspace diagnostics through an MCP-over-WebSocket IDE bridge.

Authentik MCP provides seamless integration with Authentik's API, supporting both full-featured and diagnostic modes. These enable secure, automated user, group, and system management through MCP-compatible tools.

Enables AI assistants to perform penetration testing and security assessments by exposing 60+ Kali Linux security tools including network scanning, web security testing, password cracking, exploitation frameworks, and OSINT capabilities through an AI-friendly interface.

Enables LLM coding agents to sign in with Nostr by generating NIP-07 signatures and exposing public keys, without requiring a wallet or browser extension.

Enables agents to serve interactive Auth0 Forms as MCP Apps in a sandboxed iframe, letting users complete sign-up, consent, profile, or payment flows while the agent only receives completion status.

Fast PDF tools for AI agents: 31 tools in one Rust binary. CLI, MCP server and library.

Enables Claude AI to access and run over 150 integrated cybersecurity tools through a public ngrok tunnel, supporting agentic security workflows via MCP.

An MCP authorization server implementing OAuth2/OIDC flows, supporting dynamic client registration, PKCE, consent screens, and client ID metadata documents for MCP authorization.

Enables AI coding agents to execute commands that require credentials while resolving secrets from HashiCorp Vault, injecting them only for the spawned process and redacting them from agent-visible output. It also lets users authenticate via OIDC and check which Vault secret references resolve without exposing secret values.
