What is Rivet?

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

What is Sanity?

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆ Current state

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

◆ Where it's heading

Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.

◆ Prediction

Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.

5.0

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

◆ Current state

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

◆ Where it's heading

The MCP server is becoming the main way agents read and write Sanity content, and the work has shifted from adding tools to making it safe and findable: guarded patches, accurate safety annotations, full schema lifecycle and discovery metadata. Studio and Manage continue alongside it with speed work and admin features for larger organizations.

◆ Prediction

Expect workspaceName to be removed after the migration period, and more guardrails on write tools such as patch_documents.
