What is PlanetScale?
PlanetScale is giving Postgres users budgets, guardrails, and a read-only door for agents.
The changelog is dominated by Postgres reaching parity with, and then past, the Vitess side of the platform. Database Traffic Control introduced resource budgets for query traffic, with warning thresholds before enforced budgets bite; storage became configurable at database creation; the vectorscale extension landed; and a new GCP region opened in Eemshaven. Query Insights gained negated search terms across both engines, and an Insights-only variant of the MCP server shipped without query execution tools.
What is Expo?
Expo shut down its own coding agent and kept the MCP server — it wants to be the substrate.
Two SDK releases landed in quick succession, 56 in May and 57 at the end of June, alongside steady EAS work: Maestro test insights with flake detection, automated iOS device registration in Workflows, and a general availability date for EAS Observe. On the AI side the direction reversed — the Expo MCP Server became available on the free plan in May, and in July the Expo Agent closed beta ended with the project wound down. Entry bodies in this feed are thin, so specifics beyond the headlines are limited.
PlanetScale vs Expo: editorial side-by-side
PlanetScale
0.0INFRA · APISDEVOPS
PlanetScale is giving Postgres users budgets, guardrails, and a read-only door for agents.
◆ Current state
The changelog is dominated by Postgres reaching parity with, and then past, the Vitess side of the platform. Database Traffic Control introduced resource budgets for query traffic, with warning thresholds before enforced budgets bite; storage became configurable at database creation; the vectorscale extension landed; and a new GCP region opened in Eemshaven. Query Insights gained negated search terms across both engines, and an Insights-only variant of the MCP server shipped without query execution tools.
◆ Where it's heading
PlanetScale is building the operational controls that decide whether a managed database is safe to hand to a large team. Traffic budgets, warning thresholds, storage checks before deploy requests and connection-level guardrails all address the same failure mode: one workload consuming the cluster. The Insights-only MCP variant applies that instinct to agents — give them observability and schema recommendations, withhold the ability to execute queries.
◆ Prediction
Expect Traffic Control to gain more granularity and for the Postgres offering to keep closing extension and region gaps. The scoped MCP server suggests further work on what agents are allowed to do rather than simply exposing more of the platform to them.
Expo
6.3INFRA · APIS
Expo shut down its own coding agent and kept the MCP server — it wants to be the substrate.
◆ Current state
Two SDK releases landed in quick succession, 56 in May and 57 at the end of June, alongside steady EAS work: Maestro test insights with flake detection, automated iOS device registration in Workflows, and a general availability date for EAS Observe. On the AI side the direction reversed — the Expo MCP Server became available on the free plan in May, and in July the Expo Agent closed beta ended with the project wound down. Entry bodies in this feed are thin, so specifics beyond the headlines are limited.
◆ Where it's heading
Expo is consolidating around the build, test, and observe pipeline it already owns and stepping back from competing on the agent itself. Making the MCP server free while retiring Expo Agent puts the company underneath whichever assistant a developer already uses, rather than asking them to adopt another one. EAS is where the commercial weight sits, and the recent releases all reduce the manual work between a commit and a working build on a device.
◆ Prediction
Expect EAS Observe's August general availability to anchor the next stretch, with AI effort staying on the MCP surface that connects outside assistants to Expo projects.
