"How to use Google Search" matching MCP servers:

Enables LLM agents to access Google Threat Intelligence data, including IOC search, file/domain/IP/URL analysis, and threat hunting rulesets, for security investigations.

Safety middleware for AI computer use agents that monitors, enforces policies, and provides guardrails to enable safe desktop interaction.

Enables MCP clients to authenticate with Google OAuth and securely access Google Calendar's official MCP server without exposing the Google client secret.

Enables approved MCP clients to invoke read-only Google Workspace operations through typed, OAuth-scoped HTTPS interfaces while keeping Google authorization separate from MCP access.

MCP server with built-in Google OAuth 2.0 authentication, enabling secure tool access via Google sign-in with automatic token lifecycle management and optional domain restriction for Google Workspace organizations.

Read-only MCP server for narrowly scoped Google Workspace user lookups via the Admin SDK Directory API, providing user status, search, aliases, and summary tools with strict domain and trust-boundary controls.

A remote MCP server with Google OAuth authentication, deployable to Cloudflare Workers, that provides tools accessible after signing in with Google.

Enables remote MCP servers with Google OAuth authentication, allowing users to connect and sign in via their Google account.

Routes web requests from AI tools through Tor for anonymized fetching, with selective per-URL routing to bypass Tor-blocking sites.

Enables AI agents to securely use real secrets (API keys, database passwords) by requiring human approval for each release, ensuring secrets never enter the model's context.

Scans suspicious messages, URLs, and text for scams inside any MCP-compatible AI assistant. No signup or API key needed for anonymous use.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

Enables AI agents to check URL safety before fetching content, using Google Web Risk, URLhaus, PhishTank, and AI analysis to return SAFE/SUSPICIOUS/DANGEROUS verdicts.

Enables an AI agent to check whether contracts are covered by ERC-7730 descriptors, preview how transactions and typed-data signatures would appear to a person, and simulate execution outcomes before signing, without holding keys or submitting transactions.

Enables AI assistants to search and retrieve threat-intelligence collections—including leaks, malware, attacks, suspicious IPs, threats, and group profiles—through indicator queries, filtered pagination, update tracking, and WHOIS enrichment.

Enables MCP clients to search, describe, and call roughly 180 undocumented UniFi OS/Network console API operations from a bundled OpenAPI spec, plus curated reads and typed configuration changes. Writes are off by default, require per-entity enablement, and use previews, verification, and rollback safeguards.

Enables AI agents to securely manage local credentials, obtain short-lived tokens for authenticated API access, and audit every use by purpose.

Zero-knowledge proof generation MCP server. AI agents can prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal data. Runs in AWS Nitro Enclave TEE with x402 USDC payments.

Provides DNS lookup and email authentication diagnostic tools (SPF, DKIM, DMARC, MX, etc.) for use with MCP-compatible clients. Enables natural language queries to check DNS records and email health.

MCP server to easily use compliance-trestle for OSCAL compliance workflows from any MCP-compliant client.

MCP server that integrates the Phylax verification API, enabling AI assistants to verify packages, repositories, and other MCP servers before use. It exposes tools for verifying artifacts, checking policies, and fetching attestations.

A Model Context Protocol (MCP) server for accessing the CIRCL CVE SEARCH API, providing comprehensive vulnerability and security information.

Enables Claude Code, Claude Desktop, and Cursor to perform Taiwan-specific tasks such as Labor Standards Act overtime pay calculations, Taiwan workday calculations, PII masking, real estate transaction lookup, and PDF-to-image conversion locally without API keys.

Enables AI assistants to raise, submit, approve, amend, and cancel purchase orders and onboard suppliers in ERPNext or SAP S/4HANA while enforcing procurement controls such as duplicate detection, budget limits, split-purchase checks, price tolerances, and segregation of duties.

Enables AI agents to use corporate card and expense functions, including balance checks, transaction listing, receipt compliance, expense reporting, and approval workflows, by calling existing REST APIs through a governed gateway with identity, policy, and audit controls.

Enables searching and analyzing CVEs and vulnerabilities from multiple sources, optimized for PR review scenarios to help developers identify the latest security issues.

A secure email gateway MCP server that protects AI agents from prompt injection attacks by scanning emails for malicious instructions before they reach the agent.

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.

Exposes user, membership, and role administration tools via MCP, acting as a thin passthrough to a coordinator API with RBAC enforced by the coordinator using caller bearer tokens.

Checks how long ago a package version was published and returns the newest version older than a minimum age (3 days by default), so an agent avoids brand new releases when adding dependencies. Also checks lockfiles across 15 ecosystems; read-only.

A demonstration server that reveals security risks by accessing sensitive environment variables, illustrating how MCP tools can potentially leak user data without explicit consent.

A local-first secrets vault for MCP clients that lets AI assistants use secrets by injecting them into child processes, without the plaintext ever entering the model's context.

Enables agents to search and call the full OPNsense core and plugin API, perform model-validated CRUD and settings operations, and use curated firewall, service, and network tools with optional auto-revert writes.

Enables comprehensive threat analysis for Indicators of Compromise (IoCs) including IP addresses, file hashes, domains, and URLs. It provides detailed reputation scores, security vendor evaluations, and network metadata to facilitate security assessments and risk detection.

Enables AI agents to browse customers, bookings, and availability while any booking creation or cancellation stays gated behind a human-approved, single-use token cryptographically bound to the exact arguments. Runs over stdio or Streamable HTTP and enforces the read/write separation in host code with a full audit trail.

Enables AI agents to ask users for credentials, secrets, and sensitive data through local browser forms that the model never sees, then resolve and use those values only at approved points of use. Also supports blind web capture, SSH key provisioning, and writes to .env files, SQL databases, and APIs, with the agent receiving only structural results.

Enables checking IP reputations and threat intelligence by querying Chaitin's global honeypot network and millions of defense nodes. Provides real-time IP profiling, malicious behavior detection, and threat alerts based on aggregated security data.

Enables action-bound authorization and verifiable evidence contracts for MCP tool execution, offering deterministic action planning, policy decisions, and one-use capability tokens tied to exact action envelopes.

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.

Enables AI coding agents to plan, policy-check, and cost-estimate Terraform changes while requiring human approval through Slack or CLI before any terraform apply can execute.
