Armature

Armature helps developer tool companies get discovered and used by AI coding agents. It measures how agents such as Claude Code and Codex choose tools inside real repositories, works on the docs, content and search presence that shape those choices, and gives MCP server owners analytics and evals so that agent sessions keep succeeding once a product has been picked. It is aimed at companies whose products developers install, including SDKs, APIs and MCP servers. The discoverability side is a managed service: a dedicated growth engineer runs coding agents in sandboxes on a panel of repositories that mirror real world setups, counts a pick only when the agent installs the product and wires it into the repository, and reports why agents choose a competitor when they do. Proposed changes are tested on Armature Search, the company's rebuilt version of the search that coding agents use, which it says reaches over 90% similarity with their results in its tests. The usability side is self serve: a small SDK on an MCP server feeds session analytics, session replay, grouping by use case, issue identification and nightly eval suites that catch regressions. Nothing runs inside the customer's codebase or accounts. The discoverability service, called Growth, starts from $5,000 per month and includes simulated agent sessions, weekly reviews with a shareable report, at least five new content drafts a week, a traffic dashboard and a dedicated growth engineer. MCP Analytics and Evals has a Free plan at $0 with 1,000 credits per month, usable as 1,000 sessions, 100 eval runs or any mix, then $50 per 1,000 extra credits, with unlimited users and seven day retention. A Custom plan adds priority support with an SLA, SSO and SAML, audit logs, custom retention and dedicated onboarding, priced on request.
