The governed data layer your agents build on

Connect Postgres, MySQL, or ClickHouse once. Any agent — Claude, Cursor, or one you built — works with it over MCP, learns how your company runs, and never sees a row policy doesn't allow.

Connect

One connection replaces a credential per tool. valv reads the schema, holds the policy, and exposes everything as a single MCP endpoint any agent can use.

.mcp.json — the same config for every agent 
{
  "mcpServers": {
    "valv": { "url": "https://mcp.valv.sh/acme" }
  }
}

Remember

Agents write down what they learn about your data: what an enum really means, how a metric is defined, which query shapes work. The next agent to connect inherits it instead of rediscovering it.

Knowledge
orders.status

status 5 means refunded, not cancelled — 3 and 4 are unused legacy states

metrics

MRR excludes one-time credits and is summed from subscriptions.amount, not invoices

users.plan

"biz" and "business" both appear; treat them as the same plan

connection

fiscal year starts in February; "Q1" in questions means Feb–Apr

Build

FAQ

Can I self-host?

The governance engine is open source and runs anywhere. The platform is the hosted version: teams, config in the UI, shared memory, billing.

Which databases?

Postgres, MySQL, and ClickHouse today. The layer reads your schema directly — no pipelines, no warehouse, no copies of your data.

Which agents?

Anything that speaks MCP: Claude, Cursor, Codex, or an agent you built. A chat that builds dashboards ships with the platform, already wired up.
