"How to organize my email effectively" matching MCP servers:

Checks email deliverability: audits a domain's SPF (including the 10-lookup limit), DKIM, DMARC and MX records with ranked fixes, checks a sending IP's reverse DNS and blocklist listings, and tests email headers against Gmail and Yahoo bulk sender requirements.

Enables AI assistants to search, retrieve, and send email across multiple ordinary IMAP, POP3, and SMTP mailboxes, with per-account permissions and safe sending checks.

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.

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 agents to validate email addresses through RFC 5321 syntax checks, MX record lookups, a 182,000-domain disposable blacklist, role-account detection, and an optional SMTP handshake. Runs locally via npx or as a hosted HTTP endpoint, returning explainable per-check scores at zero per-lookup API cost.

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

Enables secure chat-based interaction with PostgreSQL databases through Claude Desktop. Features GitHub OAuth authentication, role-based access control, and enterprise-grade security for database queries and operations.

Enables management of system users through a simple sample API, exposed as MCP tools for natural-language interaction.

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

An MCP server template with built-in OAuth 2.0 authorization code flow and PKCE, enabling Grok to authenticate and invoke tools such as hello and publish_page.

Enables management of system users through a simple sample API, with support for HTTP and stdio transports and forwarding of authentication headers.

Enables management of system users through a simple API, exposing two MCP tools that forward authentication headers to the upstream service.

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.

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.

Enables AI agents to interact with an Odoo ERP through tool calls that are allowlist-policy-checked, risk-scored and throttled before touching the ERP, covering record reads, writes, deletes and method execution. Every request and decision is recorded to a hash-chained, tamper-evident audit log with optional HMAC keys and anchor exports.

Enables local, self-hosted email verification with syntax and DNS/MX checks, disposable-address detection, and bounded bulk CSV processing without paid API dependencies.

Demonstrates an MCP server with a vulnerable add tool protected by SonnyLabs prompt injection detection.

Audits Ethereum/Solidity smart contracts using the Cysic Minimax model, providing automated vulnerability detection, gas optimization suggestions, and markdown report generation.

Enables creating and managing workspaces, attaching records, inviting participants, and retrieving verification and receipt lookups through tools.

Enables chatting with PostgreSQL databases via MCP tools, with GitHub OAuth authentication and role-based write access, deployable on Cloudflare Workers.

Enables Claude to list Iceberg tables and run read-only DuckDB SQL queries, including time travel by snapshot, with per-caller token authentication and audit logging.

Enables MCP clients to manage files in an isolated workspace and perform lightweight Git operations through a protected Streamable HTTP endpoint, including listing, reading, writing, searching, replacing, and deleting files plus checking status and diffs.

MCP server demonstrating Streamable HTTP with Tools, Resources, and Prompts for user registration, login, and profile management via a REST API.

Collects read-only compliance evidence from GitHub and web pages, stores it locally in SQLite, and returns opaque collection IDs for retrieval to support audit workflows.

Agent trust & data safety MCP: PII/secret redaction, email validation, sanctions screening, and OSV vulnerability checks for AI agents.

Provides redacted access to a private local knowledgebase for coding agents, allowing them to inspect files while hiding sensitive names and identifiers.

MCP server that enables AI agents to check if email addresses or domains are disposable using the isitdisposable.com API. It provides tools like check_email, check_domain, and check_batch for real-time validation.
