GreyMatter Solo

Persistent memory and orchestration for Claude Code

Install with one command

curl -sSL https://greymatter.axiomworks.ai/install | bash

Persistent Memory

Claude remembers what you teach it across sessions. Knowledge, patterns, and observations stored locally.

Expert Agents

Specialized personas for Rust, Python, TypeScript, DevOps, Security, and more. Right expert for every task.

GreyMatter Security

Every LLM call scanned for PII and prompt injection. Audit trail in your database. Built in, not bolted on.

Work Queue

Submit tasks, dispatch to AI agents, track completion. Parallel agents work while you sleep.

Quick Start

1

Install GreyMatter

curl -sSL https://greymatter.axiomworks.ai/install | bash

The installer checks for Claude Code (installs it if missing), downloads GreyMatter, sets up your database, and configures everything. Takes about 2 minutes.

2

Log into Claude Code

If you have an Anthropic API key:

export ANTHROPIC_API_KEY=your-key-here

If you have a Claude Pro or Team subscription, start Claude and type:

/login
3

Open your project and start Claude

cd your-project-directory
claude

Claude starts with GreyMatter's 17 tools loaded automatically. Type /mcp to see them.

Try these in your first session

"What GreyMatter tools do I have?"
See all 17 tools — memory, work queue, security, agents
"Remember that our API uses REST with JWT auth"
Saves to your knowledge graph — Claude remembers next session
"Create a work item to add unit tests for auth"
Queues a task for AI agents to pick up
"Scan this project for any hardcoded secrets"
GreyMatter Security scans for PII, API keys, credentials
"What patterns have you noticed in this codebase?"
Searches your accumulated observations and knowledge

Optional: Set up local LLM for semantic search

Ollama enables vector/semantic search — finding conceptually related knowledge even when exact words don't match. GreyMatter works without it (keyword search only).

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Start the server
ollama serve

# Pull the models GreyMatter uses
ollama pull nemotron-3-nano      # reasoning
ollama pull nomic-embed-text    # embeddings for search

What's in GreyMatter?

Your Data

Everything lives in ~/.greymatter/greymatter.db — a single SQLite database on your machine. Nothing is sent to any server. Back this file up; it's your knowledge graph.

GreyMatter Security

Built into every installation. Every LLM call is scanned for:

PII: Social security numbers, credit cards, API keys, credentials, phone numbers, private keys

Prompt Injection: Instruction override, system prompt extraction, role hijacking, delimiter attacks

Actions: allow (clean), redact (mask PII), block (reject injection). Full audit trail in your database.

Expert Agents

GreyMatter comes with agent personas — specialists that give Claude deep context for specific domains. Add your own by creating .md files in ~/.greymatter/soul/experts/.

Teams Mode

Solo works standalone. When you're ready for multi-machine collaboration, toggle on Teams mode to sync work items and knowledge across nodes. Your personal observations stay private — always.
