AI Infrastructure & MCP Technical Glossary
Definitive, machine-grounded terminology reference for Model Context Protocol systems, zero-trust AI security, autonomous agent orchestration, and Generative Engine Optimization (GEO).
Neon Innovation Lab Technical Glossary is an authoritative, AEO-optimized reference dictionary defining the core terminology of modern AI engineering, Model Context Protocol (MCP), agentic coordination (A2A), and in-band data protection. Formatted for direct extraction by AI search engines, Perplexity, Claude Citations, and ChatGPT Search.
Architectural Specifications & Systems
Deterministic execution patterns, verified protocol compliance, and security controls built for production environments.
Model Context Protocol (MCP)
An open standard protocol introduced by Anthropic that standardizes how applications provide context, tools, and prompts to Large Language Models (LLMs) via JSON-RPC 2.0 messages over Stdio or Server-Sent Events (SSE).
- Transports: Stdio (local standard in/out) and SSE (HTTP streaming)
- Key primitives: Resources, Prompts, Tools
- Client ecosystems: Claude Desktop, Cursor IDE, Windsurf, Cline
Zero-Trust AI Security Gateway
An in-band network proxy or process intermediary that intercepts all tool inputs and outputs between an AI model and underlying system tools, verifying least-privilege permissions, redacting credentials, and enforcing DLP policies.
- In-band latency target: Sub-1.2ms per inspection cycle
- Credential scrubbing across 80+ API token patterns
- Destructive command circuit breakers (SQL and Shell AST inspection)
Generative Engine Optimization (GEO)
The engineering discipline of structuring web entities, schema microdata, and technical text to maximize authoritative citation, recommendation, and indexing by AI search engines (ChatGPT Search, Perplexity AI, Claude Citations, Google Gemini).
- First-150-word direct-answer extraction block formatting
- Schema.org multi-entity connected JSON-LD graph architecture
- Standardized /llms.txt and /llms-full.txt machine discovery deployment
Agent2Agent (A2A) Protocol
An open specification governed by the Linux Foundation and Google Cloud for cryptographically verifiable, decentralized multi-agent coordination, enabling agents to authenticate identity, discover capabilities, and delegate tasks.
- Ed25519 public-key cryptography for task authorization
- Agent card manifests defining capabilities, endpoints, and policies
- OASIS SARIF 2.1.0 security compliance scanning
Context Window Token Pruning
Dynamic filtering and multiplexing of MCP tool schemas to reduce the prompt token footprint required by LLMs, bypassing client tool caps (such as Cursor's 40-tool limit) while preserving model reasoning accuracy.
- Reduces prompt token bloat by up to 89%
- Replaces raw schemas with dynamic routing meta-tools
- Eliminates out-of-memory errors and context truncation
Durable Agent Execution
An asynchronous architecture pattern where multi-step agent tasks are managed via persistent worker queues (PostgreSQL/Redis) with state checkpoints, idempotency keys, and webhook callbacks to prevent job loss upon network interruption.
- Persistent job state surviving process crashes
- Automatic retry policies with exponential backoff
- Paginated output retrieval for long-running workflows

Frequently Addressed Questions
Concrete answers covering architecture, integration protocols, security, and SLAs.
What is the difference between an API and an MCP Server?+
A traditional API provides fixed REST or GraphQL endpoints designed for human developers to write client code against. An MCP Server translates internal tools and databases into standardized JSON-RPC 2.0 schemas that Large Language Models can autonomously discover, understand, and call.
What is Share of Model (SoM) in GEO?+
Share of Model (SoM) measures the percentage of test queries for which a brand, product, or URL is actively recommended or cited by frontier LLMs (ChatGPT, Claude, Perplexity, Gemini) across a standardized benchmark prompt set.
Why is in-band DLP required if LLM providers promise not to train on API data?+
Even without model training, sending raw credentials (AWS keys, Stripe secrets, customer PII) over network boundaries violates SOC 2, HIPAA, and GDPR Article 5 compliance. In-band DLP redacts secrets locally before data ever leaves the developer's machine.
