"Building and Using MCP Tools" matching MCP servers:

An MCP server that exposes 43 domain tools behind 4 meta-tools, applying guardrails such as budgets, rate limits, schema validation, human-in-the-loop confirmation for mutations, PII redaction, and an append-only audit log while reducing context window usage.

MCP server for connecting to SQL Server in readonly mode. Allows any MCP client to explore the schema and run SELECT queries against a SQL Server database.

MCP server that lets AI agents use the Online Cyber Tools catalogue as a set of native MCP tools.

A comprehensive suite of HTTP and API testing tools that enables AI agents to perform requests, check endpoint health, and decode JWTs. It also provides utilities for URL parsing and detailed security analysis of HTTP response headers.

Enables cryptographic operations including hashing, encoding/decoding, ID generation, password tools, and JWT inspection via MCP.

MCP server providing 35 utility tools for AI agents including text analysis, encoding, hashing, password generation, JSON/CSV/XML parsing, regex, color, date, finance, URL metadata, SEO tags, DNS lookup, SSL inspection, and JWT decoding. Free, zero-dependency, and works with any MCP client.

Fork of @cyanheads toolkit MCP server. Added encoding functions, removed system network functions.

Provides AES-256-CBC encryption and decryption tools, a resource for algorithm details, and prompts for encrypting and decrypting messages, all runnable inside VS Code Copilot Chat.

Living off the Land intelligence for AI agents. GTFOBins, LOLBAS, LOOBins, LOLDrivers, LOLRMM, WADComs, LOLC2 and more — unified into a single MCP server.

Defense-grade cryptographic compliance and analysis tools for MCP, including FIPS 140-3 validation, CNSA 2.0 analysis, post-quantum readiness assessment, and classical cipher utilities.

Community MCP server for the Cymulate security validation platform. It exposes the full Cymulate REST API (337 endpoints) as 106 semantic tools for BAS, exposure validation, attack surface management, and platform administration.

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.

Enables high-precision detection, anonymization, encryption and decryption of personally identifiable information (PII) in text using GPT-4o-based detection and advanced cryptographic methods. Supports both deterministic encryption for searchable data and format-preserving encryption for structured identifiers.

Wraps the Remnawave API to provide per-operation MCP tools with mutation safety and data redaction, enabling secure interaction with Remnawave panel.

Provides comprehensive HIPAA compliance guidance for developers building healthcare applications. Offers tools to identify PHI, understand encryption requirements, navigate business associate rules, and ensure compliance with HIPAA Security and Privacy Rules.

Local, read-only MCP server that provides verified access to bounded.tools' signed static API, including the Web-Build Conformance report and SPDX SBOM, with byte-for-byte verification against a Sigstore-signed manifest.

Governs AI agent tool calls by checking them against Agentic Control Plane policies, returning allow/deny/ask decisions with audit logging and identity attribution for MCP clients like Claude and ChatGPT. Exposes acp_check and acp_status tools for policy enforcement and connection verification.

Provides trust scores, comparisons, and search for software entities, AI tools, packages, and MCP servers using Nerq's Trust Score system.

A template for building MCP servers with optional per-tool authentication using WorkOS AuthKit and Vercel MCP adapter.

A sovereign, MIT-licensed MCP server that provides cryptographically signed notarization for listings, benchmarks, and transactions using Ed25519. It runs offline on user infrastructure as a free alternative to SaaS notary tools.
