"Understanding and Using JSON" matching MCP servers:

MCP server for sealing and opening JSON with φ-split keyword shares and benefit checks.

Production-grade MCP Gateway in Go featuring dynamic OpenAPI tool registration, RBAC governance, in-flight PII/DLP redaction, and structured JSON audit logging.

MCP server that gives AI agents paid tools to de-risk costly actions: dependency vetting, x402 endpoint verification, JSON repair, and URL reading. Fronts the Guard HTTP API at guard.fabtally.com.

Enables LLMs to analyze network packet captures (PCAP files) from local or remote sources through a modular architecture. Supports DNS traffic analysis with structured JSON responses for network security and troubleshooting tasks.

Autonomous synthetic health checks, JSON-RPC 2.0 handshake validation, breaking schema drift detection, and credential leak scanning for remote MCP servers.

Transparent Go proxy that intercepts, signs, rate-limits, redacts, and audits all MCP JSON-RPC tool calls without modifying client or server. Stores to JSONL or SQLite with HMAC-SHA256 signatures.

An MCP server that exposes a mock email verification tool over stdio transport, providing structured JSON results with statuses valid, invalid, or risky.

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

Enables AI assistants to interact with FortiManager for centralized firewall policy management, device provisioning, and network configuration through the FortiManager JSON-RPC API.

Enables subdomain enumeration and discovery by querying the Subdomain Scan1 API. Returns all subdomains for a given domain in JSON format.

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 AI agents to perform security audits on pull request diffs by detecting secrets, dangerous code patterns, and new dependencies, outputting structured JSON for generating PR review comments.

Provides a secure enterprise gateway bridging Rovo, Jira, Confluence, and external IDEs to SEOSiri's MCP suite with data masking, governance, and JSON-RPC standardization.

This server enables interaction with SailPoint IdentityIQ through SCIM API endpoints, allowing MCP clients like Claude Desktop to manage identity resources using natural language.

Enables authenticated user profile retrieval via the 'whoami' tool, using OAuth2 and Asgardeo.

Enables AI agents to scan projects for secrets, manage incidents, and create honeytokens using GitGuardian's API.

Creates and manages encoded messages using zero-width characters and advanced Unicode steganography techniques, enabling quantum-themed puzzle generation with hidden secrets.

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.

mcpwall is a deterministic security proxy for MCP tool calls — iptables for MCP. It sits between the MCP client and server, intercepting every JSON-RPC request and enforcing YAML-defined policies.

Public read-only MCP server for turva.dev's agent-readiness audit, enabling AI agents to query service catalog, security evidence, and engagement principles via structured JSON.
