"Connecting WhatsApp with Evolution email/calendar client" matching MCP servers:

Governs and automates WhatsApp messaging for AI agents with security controls like recipient allowlisting, secret scanning, rate limiting, and audit logging.

Enables querying WhatsApp OSINT API to gather intelligence on WhatsApp numbers, including business verification, user status, privacy settings, linked devices, and profile pictures.

An open-source MCP server that provides AI agents with secure access to read, search, and manage emails via Microsoft 365 and Gmail. It features security-first defaults like recipient allowlists and markdown content conversion to facilitate safe agent interaction with mailboxes.

A local MCP server for Gmail with strict alias whitelisting, allowing AI clients to search, read, reply to, and send emails only from explicitly whitelisted alias addresses while keeping all other mailbox content unreachable.

Enables agents to interact with the Human Is Offline protocol by reading authority cards, submitting encrypted ask-first notes, and fetching delegation receipts.

Comprehensive email validation MCP server that checks syntax, MX records, disposable domains, role-based accounts, SPF/DKIM, typo suggestions, and risk scoring.

An MCP server that provides email verification, bulk list cleaning, and signup risk assessment tools. It exposes three typed tools for agents: verify_email, clean_email_list, and assess_signup_risk, with real DNS MX checks and disposable domain detection.

Enables AI assistants to read, create, update, move, and delete calendar events, list calendars, and query free/busy across multiple independent Google accounts through a single interface, with each account routed explicitly and gated by role-based access control. It also includes a built-in personal time-management assistant and stores each account's OAuth tokens in a local encrypted vault.

Implements a secure MCP server with API Key and JWT authentication, providing tools like echo, login, secure_action, and admin_action. Includes MCP Inspector integration for testing and debugging.

Audits email deliverability configuration for a domain, checking SPF, DKIM, DMARC, and MX records, returning a score and recommendations.

A local stdio MCP server that authenticates to remote OAuth-protected MCP servers using the client_credentials grant, handling token acquisition and request forwarding.

Enables AI agents to record structured pitfalls (problem, root cause, solution), query experience others have already verified, check an agent's reputation, and repay trust signals when adopting someone else's findings. Read operations are anonymous while writes require a free identity credential.

Enables role-based order management through MCP tools, allowing users to view and refund orders according to their permissions (USER, MANAGER, ADMIN) with audit logging and JWT authentication handled by a FastAPI client.

Provides email verification as a tool, performing syntax validation, domain verification, and disposable-domain risk detection.

A wrapper for mcp-remote that provides secure authentication for protected MCP servers using Adobe IMS or Okta OAuth flows. It features automated token management, validation, and background refreshing for seamless access to remote resources.

Analyzes raw email headers and emails for phishing, spoofing, and BEC using AI forensics, SPF/DKIM/DMARC/ARC validation, and IP reputation checks. Exposes analyze_email, get_analysis, and list_analyses as MCP tools.

Email validation MCP server using MailboxValidator API to determine validity of an email address.

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.

Demonstrates how to secure an MCP server with OAuth 2.1 using AWS Cognito, with support for dynamic client registration and client ID metadata documents.

Enables secure filesystem access with privacy controls using .mcpignore files to block MCP clients from reading or writing sensitive files and directories while allowing directory browsing and search.
