Graforest MCP Server

Build knowledge graphs with AI. 13 tools for creating, populating, searching, and exploring knowledge graphs through the Model Context Protocol.

What Is This?

Graforest MCP lets AI agents (Claude, Cursor, VS Code, etc.) build and query knowledge graphs. No database setup. No Neo4j config. Just tell your AI agent what you want to know.

"Create a knowledge graph about organic chemistry and populate it from my notes"
→ 2 minutes later: Searchable knowledge graph with entities and relationships

The AI agent handles intelligence (entity extraction, reasoning). Graforest handles data (storage, search, traversal).

Installation

pip install graforest-mcp

Quick Start

1. Get Your API Key

Visit graforest.ai/settings and create an API key (gf_sk_...).

2. Configure Your AI Agent

VS Code — Add to .vscode/mcp.json:

{
  "servers": {
    "graforest": {
      "command": "uvx",
      "args": ["graforest-mcp"],
      "env": {
        "GRAFOREST_API_KEY": "gf_sk_your_key_here"
      }
    }
  }
}

Cursor — Add to .cursor/mcp.json:

{
  "mcpServers": {
    "graforest": {
      "command": "uvx",
      "args": ["graforest-mcp"],
      "env": {
        "GRAFOREST_API_KEY": "gf_sk_your_key_here"
      }
    }
  }
}

Claude Desktop — Add to claude_desktop_config.json:

{
  "mcpServers": {
    "graforest": {
      "command": "uvx",
      "args": ["graforest-mcp"],
      "env": {
        "GRAFOREST_API_KEY": "gf_sk_your_key_here"
      }
    }
  }
}

13 Tools

Provisioning (3 tools)

Tool	Description
create_knowledge_project	Provision a new knowledge graph (Neo4j)
list_knowledge_projects	List all graph projects
delete_knowledge_project	Delete a graph project permanently

Data Write (2 tools)

Tool	Description

---

3-Call Ingestion Workflow

The recommended way to populate a knowledge graph from text:

1. ingest_text_content(project_code, text) → Returns the graph schema + extraction instructions
2. LLM extracts all entities and relationships from the text (guided by the instructions)
3. add_knowledge_nodes + add_knowledge_relationships → Bulk write everything

The AI does the thinking. Graforest stores the results.

Cloud Deployment (LogicBlok Module)

Graforest MCP deploys as a LogicBlok module through the RationalBloks platform. No kubectl, Docker CLI, or cluster access needed.

Deploy via RationalBloks UI

1. Log in at infra.rationalbloks.com
2. Select the Graforest project → Modules → Deploy Module
3. Settings:
   • Name: graforest-mcp
   • Type: logicblok
   • Repo: https://github.com/graforest/graforest-mcp
   • Dockerfile: Dockerfile (root of repo)
4. Set environment variables:
   • GRAFOREST_RB_API_KEY — Graforest service account key (rb_sk_...)
   • RATIONALBLOKS_MCP_URL — https://logicblok.rationalbloks.com
   • TRANSPORT — http
   • HOST — 0.0.0.0
5. Deploy. The platform handles: clone → build → push → K8s → TLS.

What the Platform Creates

Resource	Value
Namespace	customer-{project_code}-staging
Domain	{module_code}-mod.customersblok.rationalbloks.com
Port	8000 with /health probes
TLS	Auto-provisioned by cert-manager

Dockerfile

The included Dockerfile meets the LogicBlok module contract:

• Port 8000
• /health endpoint
• Non-root user (UID 1000)
• Multi-stage build with UV dependency caching

Architecture

AI Agent → graforest-mcp → Graph APIs (Neo4j databases)
                         → RationalBloks API (infrastructure provisioning)

• No AI inside the MCP server — the LLM is the intelligence, Graforest is the data layer
• Dual transport: STDIO (local IDEs) + HTTP/SSE (cloud deployment)
• API key auth: gf_sk_ prefix for all Graforest keys

Resources:

• graforest://docs/getting-started — Quick start guide
• graforest://docs/knowledge-graph — Knowledge graph concepts

Prompts:

Environment Variables

Variable	Required	Default	Description
GRAFOREST_API_KEY	Yes (STDIO)	—	Your Graforest API key
TRANSPORT	No	stdio	Transport mode: stdio or http
PORT	No	8000	HTTP server port
HOST	No	0.0.0.0	HTTP server bind address
