"Let's Encrypt" matching MCP servers:

Enables AI agents to manage Nginx Proxy Manager (reverse proxies, streams, redirects, and Let's Encrypt certificates) through natural language commands.

Let's your agent access the heroku platform

Slim OPNsense MCP Server — 62 tools for managing firewall infrastructure via the OPNsense REST API. Covers DNS/Unbound, Firewall rules, Diagnostics, Interfaces, DHCP (ISC + Kea), System/Backups, ACME/Let's Encrypt, and Firmware. No SSH, no shell, API-only with 3 runtime dependencies. AGPL-3.0 + Commercial dual-licensed.

Enables management of Nginx Proxy Manager instances for configuring proxy hosts, requesting Let's Encrypt SSL certificates, and managing access lists. It allows users to control their web proxy infrastructure through natural language commands in MCP-compatible environments.

Free SSL/TLS scanning and Let's Encrypt certificate issuance (private key stays local), plus certificate-expiry monitoring via one MCP server. Public scan and cert tools need no account.

Enables users to encrypt and decrypt data, generate keypairs, and list supported algorithms through MCP, with decryption keys supplied via environment variables or files rather than the model.

A standalone MCP server for managing SSL/TLS certificates across FortiGate, Windows, Linux, and Fortinet devices using Let's Encrypt with Cloudflare DNS-01 challenges.

Rust-powered PDF toolkit over MCP: create, read, and analyze PDFs; extract text and entities for RAG; convert to Markdown; split/merge/rotate/reorder pages; manage form fields and annotations; encrypt documents. Runs locally via uvx oxidize-mcp.

An MCP server that gives AI agents durable, temporal memory over local markdown vaults, with tools for searching, asserting facts, querying point-in-time state, and reinforcing useful knowledge.

locidx

MCP server for PDF manipulation — create PDFs from Markdown with tables and formatting, fill forms, merge, split, encrypt, add QR codes, and more. 16 tools, zero external binaries, TypeScript-native. Install with npx -y @aryanbv/pdf-toolkit-mcp.

A Model Context Protocol server that brings the capabilities of enigmapython library to LLMs, allowing them to encrypt and decrypt messages using historically accurate Enigma machine emulators

Secrets vault for Claude Code. Encrypt API keys, tokens and passwords with AES-256. Full audit logs, MCP access rules, and zero-knowledge mode. Secrets never appear in chat.

A simple Model Context Protocol server that provides real-time weather data to AI agents like GitHub Copilot, allowing users to get current weather information for any city through natural language queries.

Integrates AI safety analysis, red-teaming, and prompt auditing directly into MCP-compatible clients like Claude Desktop and Cursor IDE, allowing real-time analysis of prompts and detection of jailbreak attempts.

Enables AI assistants to perform PDF operations like merge, split, compress, convert, encrypt, OCR, and summarize using natural language.

Enables encrypting and decrypting plain-text messages with AES-256-CBC using any passphrase, with automatic scrypt key derivation and a fresh random IV per call. It also exposes a resource describing the algorithm and ready-to-use prompts, and can be run directly inside VS Code Copilot Chat or the MCP Inspector.

A proxy server that sits between MCP clients and servers, providing authentication, tool discovery, caching, and guardrail enforcement to protect MCP servers from malicious inputs.

Zerion MCP let's your agent analyze EVM and Solana wallets and summarize total portfolio value, top holdings, DeFi positions, recent transactions, PnL and more.

Enables document conversion and processing through MCP, including Office/PDF/Markdown conversions, OCR, and PDF operations like split, rotate, encrypt, and extract.
