"Let's Encrypt" matching MCP servers:

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

Enables AI agents to perform 13 PDF operations (merge, split, compress, watermark, encrypt, and more) on local files via MCP.

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.

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

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.

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.

Enables timelock encryption using the Shutter Network, allowing users to encrypt messages that can only be decrypted after a specified future time. Supports natural language time parsing and provides trustless time-delayed communications.

A testing environment for MCP server setup and client-server interactions, allowing users to verify basic MCP server functionality and test client-server communications including shell command execution.
