Built for people and machines.

Open District speaks the Model Context Protocol. Point any MCP client at one endpoint and your agent gets the same query, search, and audit surface the web app uses, under an API key with explicit scopes.

query search schema catalog topology metrics and 4 more tools, documented in agents.md

10 MCP tools today. All read-only by default, all written to the audit log. Full reference in agents.md.

Read agent setup

Streamable HTTP transport. Keys are issued per tenant with explicit scopes. Requests are written to the same audit log as the web app.

tool: query
sql:  "SELECT title, source_url, published_at
       FROM federal_register_notices
       WHERE published_at > now() - interval '7 days'
       ORDER BY published_at DESC LIMIT 20"

Every result row carries its source record. Citations are not an add-on. They are how the store works.

Built for control and accountability.

Private by default. Audited by design.

Permissions

Every query runs under a tenant context enforced by row-level security. API keys carry explicit scopes; users hold role-mapped permissions.

Privacy

Tenant data is isolated at the database layer, not just filtered in the app. Personal context stays per user.

Approvals

High-impact actions require human sign-off before execution.

Audit

Every query and result is recorded to an append-only audit log with actor, scope, and timestamps, queryable like any other table.

Sign up

Early access is open.

Request access, get an API key after review, and connect your first source.

Developers: API keys are issued in-app after you have an account.
