"Notion - Productivity and Note-Taking App" matching MCP servers:

Enables MCP clients to access Notion through a permission-checking proxy that restricts operations to a configured root page and its subtree, while blocking unauthorized tools. It also handles Notion OAuth and validates signed permission settings.

Enables AI agents to inspect any public domain’s web technology stack, email deliverability and DNS health (MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI), and HTTPS security posture with typed JSON scores and remediation-ready findings, plus history, bulk checks, monitoring alerts, and reverse technology lookups.

Brings interactive blue-team security operations into AI hosts, enabling alert triage, attack discovery, case management, detection rules, threat hunting, and sample data generation with rich inline UIs.

Enables enterprise-managed authorization for MCP on Azure App Service, with deployable Entra OAuth and a local EMA ID-JAG lab exposing whoami and authorization_model tools.

A stateless remote MCP server that lets AI agents anonymously submit encrypted reports of alignment and safety failures to leaks.md (what others did) and confession.md (what the agent itself did), returning a receipt without accounts or keys. It exposes public tools such as submit_leak and submit_confession over Streamable HTTP.

Enables applications to scan model replies for leaks, sanitize output, authorize model-proposed actions with signed single-use grants, and optionally score prompt injection in a way that can only tighten enforcement decisions.

Enables secure MCP-based HR operations, such as verified hr_whoami calls, through workload identity and authenticated Hub dispatch across managed and standalone deployments.

Enables existing apps to expose their users and data to external AI agents via MCP with OAuth 2.1 authentication and scoped tools.

An MCP server that enables interaction with the Firebase App Check API, allowing users to verify and manage the authenticity of requests to Firebase backend services through natural language.

This MCP server implements a secure OAuth 2.1 authorization server with Google login, enabling authenticated tool execution and a user interface for MCP applications.

A hardened MCP server that enforces authentication via Easy Auth and OAuth, manages secrets with Key Vault, and restricts network access using VNet integration and API Management, enabling secure tool invocations through a fully private infrastructure.

A secure server that enables AI agents to access 2FA codes and passwords from the Authenticator App, allowing them to assist with automated login processes while maintaining security.

Enables AI agents to securely reach enterprise tools and other agents through a governed gateway with pinned tool definitions, delegated authorization, content inspection, human approval, and signed audit trails.

Enables named, authenticated callers to run read-only introspection of a Google Cloud project and to read and write per-tenant notes that stay isolated between callers. Every request is scope-checked against a reviewed policy, rate-limited per caller, and audited without ever logging argument values.

A lightweight stdio-to-http relay that enables the GitHub MCP server to authenticate using a GitHub App instead of a Personal Access Token. It automatically manages fine-grained permissions and short-lived tokens for secure, organizational AI agent workflows.

Validates URLs and checks their reputation to help identify AI hallucinations and verify web page authenticity.

Compare service-grant changes, tool alias origins, and saved MCP tool definitions with Gooo rules. Reports preserve incomplete-capture uncertainty and source bindings. No grants are applied and no compared tools are invoked.

Enables encrypted messaging via Signal, SimpleX, and Session through a unified API, supporting message sending, polling, and key management.

Lets your assistant check text for credentials and personal details before passing it to another tool. Runs on your device over stdio and makes no network calls.

Exposes cQnce human-in-the-loop authorization as MCP tools, letting AI agents request and await human approval for risky actions. Includes request submission, monitoring, and project/team management capabilities.

Enables generating secure passwords, exposing password policies, and providing reusable prompt templates for secure password creation through MCP primitives.

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.

Tamper-evident receipts for AI agent actions. The notary layer for agent-to-agent transactions.

Enables AI agents to discover and invoke backend tools over MCP JSON-RPC while enforcing 3-legged OAuth 2.0 identity propagation, role-based access control, and protocol transcoding to REST APIs.

Enables agents to read and report, and to carry human-authored updates into systems of record after human consent, while structurally preventing autonomous writes of commitments like owners, due dates, or statuses.

Enables AI agents and apps to check URLs, domains, IP addresses, phone numbers, emails, crypto wallets, IBANs, mobile apps, and payment handles for scam, phishing, and fraud risk, returning verdicts, probabilities, facts, and reason codes.

Enables developers to wrap existing MCP servers with a deterministic policy enforcement gate that intercepts tool discovery and tools/call requests over stdio, allowing only authorized calls to reach the downstream server. It supports dynamic tool exposure or hiding, allow/deny/approval-required decisions, configurable error disclosure modes, and Ed25519-signed retry credentials for approved workflows.

Enables enterprise MCP clients and partner agents to execute tenant-isolated underwriting, claims, and compliance workflows with durable step checkpointing, evidence-grounded tool calls, and deterministic PDF citation receipts. It supports A2A task dispatch and MCP JSON-RPC operations while blocking cross-tenant access and ungrounded deliverables.

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.

Enables AI agents to manage a consumer todo list through an authenticated MCP endpoint backed by Workers KV and Stytch-managed user and client identity.

Prepares and validates an authenticated PipMCP connection so AI coding agents can discover and call hosted provider tools with schemas, scopes, and approval controls.

Enables AI agents to discover and execute tools via a secure MCP server with JWT authentication, RBAC, rate limiting, and audit logging.

Enables automated review and analysis of network security controls (AWS Security Groups, Network ACLs) using natural language queries. Supports NSC configuration reviews, network segmentation testing, and identifying security gaps through conversational LLM interaction.

Provides governed MCP tools for querying optionally restricted Microsoft Sentinel/Log Analytics tables and optional Defender XDR hunting data, retrieving incidents and entities, and—for agent identities only—adding attributed incident comments, with Entra ID authentication, KQL validation, rate limits, and redacted audit logging.

Enables solving rotate/image-orientation CAPTCHAs through a single MCP tool by submitting parallel solving attempts and aggregating their angle estimates. It exposes this capability over a Streamable HTTP transport with configurable timeouts and success thresholds.

A deployable MCP server template for Cloudflare Workers that provides Google OAuth authentication and comprehensive analytics tracking of tool usage, performance metrics, and user behavior.

Stateless Streamable HTTP MCP endpoint with OAuth 2.1 authentication via Cloudflare Workers, supporting PKCE, DCR, and token introspection.

Demonstrates OAuth2/OIDC authentication for MCP servers using Asgardeo, with JWT validation and a sample weather tool to showcase secured API access.

A local MCP server that lets AI agents read, create, and update end-to-end encrypted static.md notes, merging edits with people typing in the same note. Keys and plaintext stay on the user's computer, so the service only ever receives ciphertext, note ids, and titles.

Enables pre-approving deliveries and visitors at your gate via the NoBrokerHood resident app, so you or an LLM can automate gate access.
