Hermes Memory MCP: The Cognitive Substrate

A high-fidelity, multi-tier memory system designed for the SuperInstance Ecosystem. This Model Context Protocol (MCP) server provides a standardized interface for autonomous agents to persist, retrieve, and manage cognitive states across different levels of abstraction.

🧠 The Multi-Tier Memory Matrix

The core innovation of this system is its non-linear, multi-tier storage architecture. Rather than a flat "key-value" store, Hermes organizes intelligence into three distinct tiers:

Tier

Cognitive Level

Description

Use Case

Semantic

The "Why" & "How"

High-level reasoning, design principles, and philosophical intent.

"Why was the sensor fusion logic implemented this way?"

Structural

The "Who" & "What"

Entity maps, agent taxonomies, repo structures, and SOPs.

"What is the current hierarchy of the Claw fleet?"

Technical

The "Where" & "How Much"

Absolute paths, API schemas, hardware constraints, and environmental facts.

"What is the absolute path to the sonar logs?"

🛠 Agent Capabilities (Tools)

Agents interacting with this server have two primary superpowers:

1.

Purpose: Commit a new piece of intelligence to the substrate.

  • Parameters:

    • : ( | | ) — The ownership domain.

    • : ( | No files replaced | ) — The modification type.

    • : ( | | ) — The cognitive layer.

    • : The actual declarative fact or instruction.

    • : Metadata for high-speed retrieval.

2.

Purpose: Perform targeted retrieval of intelligence.

  • Parameters:

    • : Natural language or keyword search.

    • : Filter by cognitive level to reduce noise.

    • : Filter by ownership.


🤖 Agent-to-Agent (A2A) Native Instructions

To maximize the efficacy of this memory center, agents must adhere to these Communication Protocols:

A. The "Declarative Fact" Protocol (DFP)

Agents must avoid writing "intent" or "transient thought" to the memory substrate. Memory should only contain stabilized intelligence.

Bad Practice (Transient/Intent)

Good Practice (Declarative Fact)

"I am going to try to find the log file."

"Target: Log directory identified at ."

"I think the user wants concise answers."

"User preference: Concise, technical-first communication styles."

"I will record the sensor data every 10m."

"SOP: Sensor telemetry is recorded at 10-minute intervals."

B. The "Handover Pattern"

When an agent enters a "Task Completion" state, it must perform a Memory Handover to ensure its successor doesn't start from zero.

  1. Identify: What was learned? (e.g., a new API endpoint).

  2. Tier: Which tier does it belong to? (e.g., ).

  3. Commit: Call .
