Exograph MCP Support Now Available

Secure AI Access to Your Database

AI applications need rich data access, but must be securely scoped to each user.

Exograph provides built-in access control, optimized queries, and an incredible developer experience.

MCP Server using Exograph

Why Exograph?

Database to AI in Minutes
Transform any existing Postgres database into a secure MCP server with a single command. Import your schema, add access control rules, and get intelligent database access without rebuilding infrastructure.
Secure by Design
Define your domain model once with built-in access control. LLMs can query freely while Exograph ensures they only see authorized data—no more choosing between security and functionality.
Beyond MCP Servers
Get a complete backend solution with MCP server, GraphQL APIs, schema migrations, testing framework, and observability. Everything follows the same access control rules you define once in your domain model.
Production-Ready from Day One
Deploy anywhere as a single binary with OpenTelemetry observability, comprehensive testing tools, and Git-friendly development workflow. Focus on building your AI application, not database plumbing.

Build it yourself in 5 minutes!

Bring Your Own Database

Start with a Postgres database you already have. Exograph generates a complete domain model from your database automatically with relationships and all. You can then tune the model to your needs.

exo new finance-mcp --from-database
Imported tables:
public:
accounts, advisor_performance,
audit_logs, branches,
compliance_reports, customers,
customer_account_summary,
financial_advisors,
investment_portfolios,
transactions
 
A new project has been created in the finance-mcp directory.
To start the server, run cd finance-mcp and then exo yolo!

Add Access Control

Evolve the model to your needs. Secure your domain model through access control rules.

Express rules such as "only admins can create customers" or "only customers can see their own data".

@access(AuthContext.role == "admin")
type Customer {
  @pk id: Uuid = uuidGenerateV4()
  name: String
  advisor: Advisor?
  accounts: Set<Account>
}

@access(AuthContext.role == "admin")
type Advisor {
  @pk id: Uuid = uuidGenerateV4()
  name: String
  customers: Set<Customer>
}

...

@access(query=AuthContext.id == self.id || AuthContext.id == self.advisor.id || AuthContext.role == "admin")
type Customer {
  @pk id: Uuid = uuidGenerateV4()
  name: String
  advisor: Advisor?
  accounts: Set<Account>
}

@access(query=AuthContext.id == self.id || AuthContext.role == "admin")
type Advisor {
  @pk id: Uuid = uuidGenerateV4()
  name: String
  customers: Set<Customer>
}

...

Spin Up an MCP Server

Run exo dev to get an instant MCP server, GraphQL APIs, and a playground. Changes to your model are reflected immediately—no rebuilds needed.

As your model evolves, exo schema migrate will provide a migration plan to keep your database in sync.
