Coding agents
Give Claude and Cursor safe database access
Let your coding agent read real data without handing it your production credentials. PgBeam issues a scoped connection string or a hosted MCP URL and enforces what the agent can do, in the Postgres wire protocol.
A coding agent is useful exactly because it can run arbitrary SQL, and dangerous for the same reason. The fix is not a careful prompt; a prompt is a suggestion, not an enforcement boundary. PgBeam puts the control outside the agent, in the wire between it and your database, where it cannot be talked out of the rules.
Scoped, not superuser
Issue a per-agent Postgres username and password, or a hosted MCP URL. The agent gets that, never your real database credentials, and you revoke its access with one click.
Attach a policy: read-only or read-write, specific tables and columns, masked fields, query budgets, and row caps. The policy applies to every statement the agent runs.
Enforced at the wire
PgBeam parses every statement and checks it against the policy before it reaches your database. Disallowed writes and off-limits tables are blocked with an LLM-readable error; flagged columns are masked in the result.
Because enforcement is in the protocol, it works with RDS, Aurora, self-hosted, or any managed Postgres, and with every driver and agent framework, with no code changes.
Connection string or MCP
Two front doors, one policy engine. Use whichever your agent supports.
Instant revocation
Revoke a credential or hit the kill-switch to stop one agent or all of them.
Query budgets
Cap queries per window and rows per result so a runaway loop hits a ceiling.
Audit everything
Keep an exportable record of every statement the agent ran and why it was allowed or blocked.
