Measure whether coding agents choose your product and how its tools perform
Armature is a platform and service for companies whose products need to be discovered and used by coding agents. It examines two different problems: whether an agent chooses a tool while building something, and whether the tool works reliably once an agent tries to use it. This makes it relevant to API businesses, MCP server developers and teams responsible for developer adoption.
The discoverability service runs coding agents inside a panel of repositories representing different languages, stacks and constraints. A product counts as selected when the agent installs and connects it in the repository, not merely when its name appears in an answer. Armature uses these runs to identify obstacles in documentation, installation and search presence, then proposes changes for the customer's team to review and ship. The tests run on Armature's infrastructure rather than directly inside the customer's production accounts.
MCP Analytics reconstructs sessions so teams can inspect sequences of calls, user intent and points of failure. Sessions are grouped into use cases and issues, with replays providing more detail than an aggregate request count alone. The evaluation offering extends this approach to MCP and CLI workflows, replaying scenarios on releases or scheduled runs to detect regressions. These tools help separate a discoverability problem from a product-usability problem.
The usability side is presented as self-serve, using a small SDK on the MCP server, while discoverability is a collaborative service. A developer-tool company can begin with a narrow workflow, establish a baseline and compare results after a documentation or installation change. Armature's reported agent-selection rates are measurements under its test setup, not guaranteed market-wide adoption. The useful question is whether the same representative tasks improve consistently and whether real usage shows fewer failures. Public pricing details are limited, so teams should confirm allowances and service scope before treating the free-start option as an unlimited production plan.
