What is Merge?

Merge is becoming the governance layer for agent tool access, not just a unified data API.

Merge ships a weekly digest split across three lines: the original unified API (HRIS, ATS, CRM, accounting, file storage, ticketing), Agent Handler for AI agent connectors, and Gateway for LLM routing. The unified-API half reads as a maintenance grind — every week is dominated by SharePoint, SAP SuccessFactors, Workday and Dayforce sync reliability, pagination and mapping fixes. All of July's directional news came from the other two lines, ending with hundreds of generic MCP connectors folded into the Agent Handler catalog and an AI Guardrails surface with PII detection.

What is Supabase?

Supabase is closing its most-exploited default: tables stop being public unless you say so.

The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

Merge is becoming the governance layer for agent tool access, not just a unified data API.

◆ Current state

Merge ships a weekly digest split across three lines: the original unified API (HRIS, ATS, CRM, accounting, file storage, ticketing), Agent Handler for AI agent connectors, and Gateway for LLM routing. The unified-API half reads as a maintenance grind — every week is dominated by SharePoint, SAP SuccessFactors, Workday and Dayforce sync reliability, pagination and mapping fixes. All of July's directional news came from the other two lines, ending with hundreds of generic MCP connectors folded into the Agent Handler catalog and an AI Guardrails surface with PII detection.

◆ Where it's heading

The unified API is being maintained, not expanded — new objects arrive at a trickle (expense reports in early July) while the bulk of each week goes to sync stability across existing connectors. Attention has moved to sitting between agents and the tools they call: Merge now offers auth, access control, governance and guardrails over connectors it did not build. Gateway is moving the same way, from a routing product to multi-tenant infrastructure customers resell, via Embedded Routing Stack, bring-your-own keys and per-customer complexity classifiers.

◆ Prediction

Expect the guardrails surface to deepen — PII detection and pre-run/post-run rule labels shipped in the same month, and the generic MCP connectors currently arrive without the tool safety hints Merge applied to its own catalog. The likely next step is extending that governance tooling to the imported MCP servers.

Supabase is closing its most-exploited default: tables stop being public unless you say so.

◆ Current state

The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

◆ Where it's heading

Supabase is paying down the security cost of its own convenience. Auto-exposing every public-schema table made the product fast to start with and easy to misconfigure; the fix is explicit Postgres grants, staged over six months from new projects in April to all existing projects on October 30. The RLS Tester is the same theme from the other side — the auto-exposure default only worked if row-level security was correct, and until now there was no way to check.

◆ Prediction

Expect the remaining rollout dates to hold and more of the developer experience to be rebuilt around explicit grants, with the RLS Tester graduating from preview as it becomes the tool people need to verify the new model. The October cutover for existing projects is the moment where this stops being an announcement and starts breaking things.
