Who it is for
Developers running agents against MCP servers who need to understand what happened in earlier sessions.
Overview
Armature is a review layer for MCP activity. It lists the MCP servers configured in a workspace, opens recorded agent sessions and the use cases behind them, and helps trace issues that keep recurring.
Developers can also flag capabilities the app is missing, which goes back to Armature. The sample prompt shows the intended pattern: rank workspace issues by how far their effects spread, open the worst one, and jump to a session where it appears. What the record describes is inspection, not intervention; no changes to a running agent are mentioned.

Recorded sessions are tied to recurring issues, so an investigation can move from a pattern to one specific run.
Availability
Armature is listed in the ChatGPT apps directory only. Armature has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Armature's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Armature, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
