AI & Agents
Audit-grade memory backbone for agent teams. Bi-temporal facts (event time + transaction time, with recall(as_of=...) replay), 6-step deterministic retrieval (no LLM in the critical path), conversation ingest with speaker-locked dual-pass extraction, per-tenant Postgres row-level
The NOVA MCP Security Gateway is a prompt-validation service that runs first in your Model Context Protocol (MCP) chain. It loads Nova rules (in .nov format), checks each incoming prompt against these rules, and blocks any that match high-severity security or jailbreak patterns
Context Rot Detection & Healing — gives AI agents self-awareness about their cognitive state by analyzing token utilization, quality degradation, and session fatigue. Returns health scores (0-100), model-specific degradation curves for 15+ models, lost-in-the-middle risk scoring,
Agent-first programming language designed exclusively for AI agents. Programs are JSON ASTs — no text syntax, no parser. The compiler validates structure, resolves names, checks types and effects, verifies contracts via Z3/SMT, and compiles to WebAssembly. 19 MCP tools cover the
Upload-Post is the all-in-one social media MCP server. It's the Model Context Protocol server for social media publishing, scheduling and analytics. Connect any MCP-compatible AI agent (Claude, Cursor, ChatGPT, Claude Desktop, n8n, and more) and publish, schedule and analyze content
Glutamate is a powerful desktop platform that simplifies the deployment and management of Model Context Protocol servers. It provides a user-friendly interface and robust tools for server administration, making it easier than ever to run and customize your MCP servers
The Advanced Scientific Research (ASR) Graph of Thoughts (GoT) MCP server is a highly efficient implementation of the Model Context Protocol (MCP) that allows for sophisticated reasoning workflows using graph-based representations
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
