"How to add data to Google Sheets" matching MCP servers:

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

Enables MCP clients such as Claude, ChatGPT and Cursor to answer business questions about sales, customers, orders and spreadsheets in natural language by reading live Postgres/SQLite databases and Google Sheets without exporting files or gaining write access. Guardrails include AST-based read-only SQL validation, read-only database roles, row/byte caps with pagination, PII masking, bearer-token auth for remote HTTP use, and a full JSONL audit log of every tool call.

Enables Claude and other models to read a Google Ads account and safely create, edit, pause, and budget campaigns, ad groups, ads, keywords, and bids. Every write is previewed through Google's validateOnly, approved by a person, and protected by server-side spending limits and an audit log.

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

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.

An MCP server that enables authentication and authorization with Google's OAuth2 API, allowing users to securely authenticate and access Google services through natural language interactions.

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

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.

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 agents to detect and redact PII and secrets in text, HTML, and PDF documents before they reach an LLM, with reversible placeholder, mask, or hash redaction, and to list supported detectors and redaction styles.

Enables agents to validate data safety before storing, transmitting, or logging data, preventing GDPR/HIPAA/PCI-DSS violations with clear verdicts like SAFE_TO_PROCESS, REDACT_BEFORE_PASSING, DO_NOT_STORE, or ESCALATE.

An MCP server that enables AI agents to securely add secrets to .env files by prompting the user to input the value through a local masked dialog, ensuring the agent never sees the secret.

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.

Seven read-only tools help AI agents review public breach disclosures, organization histories, incident timelines and aggregate statistics. Preserve source attribution, redaction and incomplete-coverage warnings. Local threat-text triage needs no key; no breached data, credentials or private records are collected.

Enables AI assistants to interact with security data pipelines and map data to the Open Cybersecurity Schema Framework (OCSF) through Tenzir. Provides seamless integration for processing and analyzing cybersecurity data using natural language.

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

A local-first MCP server that scores your codebase's Build Readiness by reading code and running tests on your machine, outputting a diligence-grade score and risk register without uploading your source.

Investigate fraud directly from Claude, Cursor, or any MCP-compatible client. Analyze suspicious activity with clear, evidence-backed verdicts. Pivot from a single signup to every account sharing the same device, IP address, or email inbox. Check entities against a cross-operator abuse network, review linked accounts, and efficiently process your fraud review queue. Read-only by default, with no r

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.

Governance circuit-breaker MCP server that enables AI agents to request risk-based decisions, approve or deny actions, and finalize outcomes with full audit receipts.

Enables AI agents to classify IP addresses through the VPNDetection API with read-only tools that detect VPNs, residential and datacenter proxies, Tor nodes, relays, hosting providers and CDNs, in single or bulk lookups of up to 100 addresses. It also exposes which datasets an organisation is licensed for, along with their metadata and published checksums.

An MCP server that provides comprehensive data verification in China, including identity, business, vehicle, OCR, and risk assessment services.

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.

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.

Local-first MCP proxy with BM25 tool discovery, quarantine security, Docker isolation, OAuth support, activity logging, and web UI. Routes multiple upstream MCP servers through a single endpoint.

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.

Enables querying Red Hat security data including CSAF advisories, CVEs, and OVAL streams through natural language.
