Give your AI agent
a structured world to work in.

GhostCrab is an open-source, MCP-friendly tool that helps AI agents work with structured projects over time.
Instead of relying on long chat history, scattered notes, or fragile context stuffing,
GhostCrab helps your agent work with entities, stages, rules, dependencies, blockers, and evolving project state.

Use it with the agent you already like. No new chat app. No proprietary interface. No lock-in.

WHAT GHOSTCRAB IS

What GhostCrab is

GhostCrab is a project-structuring layer for AI agents.
It helps an agent turn a fuzzy domain into something it can navigate:
people, tasks, documents, procedures, goals, constraints, dependencies, and next steps.

What GhostCrab is not

✗ Not a new chatbot.
✗ Not a replacement for your agent.
✗ Not a generic memory plugin.

A way to give your existing agent structured project state, workflow logic, and a usable map of what connects to what.

WHY PEOPLE USE IT

Most agents work well when the task fits in one conversation.

Things get messy when a project has:

→ multiple stages
→ changing status
→ dependencies
→ rules and exceptions
→ approvals
→ blockers
→ missing information
→ work that unfolds over days, weeks, or months

That is where GhostCrab becomes useful.

It helps your agent do more than answer prompts. It helps your agent work inside a real project.

HOW IT STARTS

You do not need to begin with a perfect schema.

GhostCrab is designed to help your agent guide the setup process.

Describe the project in plain English.

We want help managing employee onboarding across teams and countries.

The agent starts asking setup questions.

→ What are the main entities?
→ What stages matter?
→ What statuses matter?
→ What depends on what?
→ What rules or constraints matter?
→ What should happen first, next, or only after approval?

GhostCrab helps turn that into a structured model.

From there, your agent can inspect the project, update the state, identify blockers, surface next actions, and ask follow-up questions over time.

DIVISION OF LABOR

GhostCrab vs. your agent.

GhostCrab gives the agent structure.

GhostCrab stores and exposes the project as something navigable.

→ entities
→ stages
→ relationships
→ procedures
→ constraints
→ dependencies
→ project state

It gives the agent a better environment to reason inside.

Your agent does the reasoning.

Your agent still does the conversational work.

→ asks questions
→ interprets your intent
→ explains what is happening
→ identifies what is missing
→ proposes next steps
→ helps move the work forward

GhostCrab does not replace the agent. It gives the agent a structured world to operate in.

WHAT THIS CHANGES

What changes in daily use.

Without GhostCrab

→ pasting long notes into context
→ repeating the same setup in each new session
→ hoping the agent remembers what matters
→ rebuilding structure from prose
→ getting flat answers when the project has real complexity

With GhostCrab

→ understand what exists in the project
→ follow what depends on what
→ detect what is missing
→ keep track of project state
→ return more useful next actions
→ work across sessions without starting from zero each time

That is the practical upgrade.

USE CASES

Useful whenever your agent needs to work in a domain that has structure.

Onboarding

Model people, tasks, approvals, stages, blockers, and country-specific rules. Then ask your agent what is blocked, what is missing, and what should happen next.

See example

CRM Pipeline

Model companies, contacts, opportunities, objections, approvals, and next actions. Let your agent follow the shape of the deal instead of summarizing fragments.

See example

Compliance & Legal

Model obligations, prerequisites, validation steps, escalation paths, and missing requirements. Let your agent identify what is still needed before something can move forward.

See example

Project & Kanban

Model tasks, owners, phases, blockers, milestones, and dependencies. Let your agent guide the work instead of just commenting on it.

See example

Personal & Family

Model deadlines, documents, responsibilities, phases, and shared tasks across relocation, school enrollment, travel planning, or family administration.

BUILT FOR THE AGENT YOU ALREADY USE

Works with the agents and environments you already prefer.

Use it with OpenClaw, Claude Code, Cursor, Codex, and other MCP-compatible setups. You do not need to switch to a new interface. You do not need to adopt a new platform. You do not need to abandon the tools you already know.

Your agent stays the interface. GhostCrab extends what it can actually work with.

OPEN SOURCE

Open-source, free, and self-hostable.

GhostCrab is open-source and free.
You can run it yourself. You can use it with your own agent.
You can keep control over your data and your workflow.
You are not buying into a closed platform just to get structured agent behavior.

For a lot of users, that is not a side note. That is the reason to trust the tool in the first place.

Built on mindBrain — a structured agentic database. GhostCrab exposes three capabilities: Facettes for retrieval and filtering, Graphes for directed relationships and dependencies, Projections for compact working context. mindBrain is the structured engine underneath GhostCrab. It comes in two versions: mindBrain Personal — powered by SQLite, for individual use and small teams; mindBrain Professional — powered by PostgreSQL, for enterprise-scale deployments. For the deeper technical view, the architecture page explains how these capabilities work together in practice; the use case pages show the product in motion.

FAQ

What do I install, exactly? +

You install GhostCrab as an open-source, MCP-friendly tool that connects your agent to a structured project layer. If you want the deeper technical details, architecture page explains what sits under the hood.

Does GhostCrab replace my agent? +

No. GhostCrab is designed to extend the agent you already use. Your agent remains the conversational interface. GhostCrab gives it structured project state and navigation capabilities.

Is GhostCrab only for developers? +

No. It can be used for software and technical workflows, but also for operations, research, compliance, planning, family organization, and other structured domains.

Is this just another memory tool? +

No. GhostCrab is built for structured projects, not just chat recall. It helps agents work with entities, procedures, dependencies, constraints, and project state over time.

Can I use it locally? +

Yes. GhostCrab is open-source and designed to be run by users who want control over their setup.

Do I need a perfect model before I start? +

No. A core part of the experience is that GhostCrab helps the agent ask the right questions so the model can emerge progressively.

When your project has real structure,

your agent needs more than chat history.

GhostCrab helps your agent work with stages, dependencies, rules, blockers,
and evolving project state — without forcing you into a new interface or a closed platform.

Start with a use case. Install GhostCrab. Build a project your agent can actually navigate.
