"Understanding RPG (Role-Playing Games) or Related Topics" matching MCP servers:

A role-based access control MCP server template with authentication, role-based tool exposure, and rate limiting, enabling secure tool management for AI assistants.

A zero-dependency Node.js playground for debugging how MCP clients authenticate to an MCP server over HTTP.

A secure PostgreSQL Model Context Protocol server that provides read-only database access through tools like schema listing, object inspection, query execution, and EXPLAIN analysis, with database-enforced access control via read-only transactions and a minimal role rather than SQL text parsing.

Provides automated EU AI Act compliance tools, including risk classification, role determination, transparency disclosures, content watermarking, deepfake labeling, and security threat detection.

Enables LLMs to safely query databases through a secure gateway that masks PII, enforces role-based table access, rate limits requests, and logs all queries, with Prisma support.

Enables Claude Desktop and Claude Code to inspect a Postgres schema and run read-only SQL queries against a demo database through the tools describe_schema and query_readonly. Every proposed query passes the same deterministic guardrails — SELECT-only, allow-listed tables, enforced row limits, statement timeouts and a read-only role — before execution.

MCP server for enterprise authentication and authorization — JWT validation, OIDC token inspection, OAuth 2.0 introspection, and role-based access control for AI agents.

Enables MCP clients to connect to miyoushe and HoYoLAB accounts with QR login, encrypted credential storage, multi-account and game role discovery, daily notes for Star Rail, Genshin Impact, and Zenless Zone Zero, plus stamina alert checks with deduplication.

Exposes user, membership, and role administration tools via MCP, acting as a thin passthrough to a coordinator API with RBAC enforced by the coordinator using caller bearer tokens.

Enables AI agents to list metrics and dimensions, inspect definitions, and run governed metric queries against Apache Iceberg tables through a semantic layer, without writing SQL or accessing raw rows or columns outside their role.

Provides read-only search and retrieval of archived emails, archive statistics, health, and ingestion sources, with an optional administrative toolset for user, role, reindexing, and queue management.

Enables governed access to corporate Postgres databases via MCP, supporting read-only queries, confirmed data and schema changes, query explanation, audit trail retrieval, and role-based policies with optional Vault secret integration.

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.

Enables agents to validate email addresses through RFC 5321 syntax checks, MX record lookups, a 182,000-domain disposable blacklist, role-account detection, and an optional SMTP handshake. Runs locally via npx or as a hosted HTTP endpoint, returning explainable per-check scores at zero per-lookup API cost.

Azure PIM role activation MCP server allowing role activation through natural language, with support for saving frequently-used roles as favorites and activating them with a single command.

A local-first AWS security tool that uses graph theory to discover attack paths (e.g., Internet → Role → DB) and prioritize remediations. It allows agents to perform read-only security audits and generate Terraform fixes without data exfiltration.

A small MCP server that lets an LLM query PostgreSQL, MySQL, MariaDB, SQL Server, or SQLite databases safely — read-only, role-restricted, and with sensitive data blacked out.

Enables secure role-based querying of company documents across different departments (Engineering, Finance, HR, Marketing) with access control that restricts data visibility based on user roles. Provides retrieval-augmented generation with source citations and metadata for trusted corporate knowledge access.

A Model Context Protocol server that enables management of Keycloak users and realms through a standardized interface, providing tools for user creation, deletion, role assignment, and group management.

Enables Discord server moderation actions including kick, ban, timeout, role management, channel operations, audit logs, and member management through MCP tools.
