Nacos vs Sanity
A side-by-side editorial comparison of Nacos and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
Nacos vs Sanity: at a glance
What is Nacos?
Nacos is hardening the AI registry it just built, and closing the door behind its deprecated APIs.
Nacos has finished turning a microservice registry into a registry for AI agents — MCP, Skill, Prompt and Agent resources all live under one AI Registry — and the 3.2 line is now spending its releases making that surface safe to operate. The newest patch adds server-identity authentication to internal JRaft traffic, puts MCP tool imports from private addresses behind an administrator allowlist, and returns HTTP 410 on deprecated AI APIs by default. The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.
What is Sanity?
Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates
Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.

Nacos

Nacos is hardening the AI registry it just built, and closing the door behind its deprecated APIs.
◆ Current state
Nacos has finished turning a microservice registry into a registry for AI agents — MCP, Skill, Prompt and Agent resources all live under one AI Registry — and the 3.2 line is now spending its releases making that surface safe to operate. The newest patch adds server-identity authentication to internal JRaft traffic, puts MCP tool imports from private addresses behind an administrator allowlist, and returns HTTP 410 on deprecated AI APIs by default. The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.
◆ Where it's heading
Two threads are running at once: 3.3.0-BETA is extending the registry to protocol-neutral agent registration and vector-based resource discovery, while 3.2.x closes off the compatibility and security debt that the fast AI-registry build-out accumulated. The breaking notice in 3.2.4 — an irreversible JRaft authentication transition and 410s on legacy endpoints — reads as the project deciding the AI surface is stable enough to stop carrying old shapes. Operator-facing work, not new capability, is where the 3.2 series is heading.
◆ Prediction
Expect 3.3.0 to go final on the agent-registration and vector-discovery work while 3.2.x keeps shipping security hardening; the temporary nacos.core.api.compatibility.enabled switch is the obvious next thing to be removed.
Sanity

Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates
◆ Current state
Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.
◆ Where it's heading
Sanity is building the MCP server into a production-grade write interface for AI agents. The `ifRevisionId` guard in v2.33 — which causes publishing to fail if a draft changed since the caller read it — is the kind of concurrency safety needed before AI agents can reliably edit live content. Studio stability work is catching up after a period of fast feature shipping. Expect MCP tool coverage to broaden and the auth/schema layers to continue hardening for enterprise-scale deployments.
◆ Prediction
The next MCP server release will likely add more write-path safety features — document locking or conflict detection. Studio v6.15 will address remaining edge cases exposed by the MCP surface's broader read/write coverage.
