About
About AgentsUse
AgentsUse is a startup building tools for AI agents: APIs, MCP servers, and SDKs that give a model a defined way to search, read, compute, and act. The company starts from the tool layer because that is where agent capability becomes real, and where it becomes risky.
Company facts
The public catalog is the map we build from. It records what agents can call today: tools, MCP servers, frameworks, and reference stacks, with setup, limits, and sources attached. Publishing the map serves two purposes. Builders get a record they can check, and AgentsUse gets a clear view of the gaps worth building into.
The second pillar is the harness: the runtime layer that validates a tool call, decides whether it may run, bounds retries and result size, and records what happened. The Harness pillar publishes the patterns we work from, drawn from official framework documentation, the MCP specification, and production engineering writing.
Catalog profiles are checked against primary sources: the official repository, package registry, documentation, and pricing pages. Each profile carries a checked date, separates sourced facts from vendor claims, and leaves unknown fields empty. Metrics such as GitHub stars are maintenance signals, not ratings. The full rules live on the methodology page.
Business model
Readers pay nothing, ever: the public catalog, guides, harness patterns, and comparisons are free. The plan is for the vendors behind listed tools to pay, never the readers. Two vendor offers are planned and neither can be purchased yet: a Verified Listing and a single labeled Sponsored Category Placement per category. Neither changes where a listing sits in the default ordering. Listings, rankings, and conclusions are never for sale. We are not paid by any company listed here today, and there are no sponsored placements and no affiliate links. See pricing for the offers.
Built with agents, under a harness
AgentsUse is built and run the way it tells other builders to work. AI agents do the research legwork inside the ingestion pipeline: they classify candidate tools and servers, and draft verification notes and comparison points. Deterministic schema checks validate the shape of every draft, and a human reviews each one against primary sources before anything can publish. No agent output reaches a public page on its own.
That operating model is also the product direction. The breadth of this catalog and the depth of its checks, maintained by a small solo-founded company, come from agents working as operators under those controls. What AgentsUse sells is the same discipline: tools, APIs, and harness patterns that expand what a small team can build and operate when agents do the legwork and the harness keeps them bounded.
The catalog grows only when the evidence supports a new page. Candidate and draft records stay unpublished, and comparison and integration pages stay gated until both sides are verified. No vendor can pay to change a listing, ranking, or conclusion. Sponsored placement, if offered, will be labeled and kept separate from editorial results.
The guides cover the judgment around the tooling: delegation, instructions, permissions, memory, evaluation, cost, security, testing, and handoff. Profiles link to a guide when the guide changes how a tool should be operated; guides link back to the catalog when a named tool is the practical next step.
The AgentsUse framework is in the works, not shipped. It is being built from the patterns in the Harness pillar and the gaps the catalog keeps exposing: compatibility answered from verified records, permission and audit controls that travel across runtimes, and reference harness patterns as code. No date is promised. When something ships, it will be listed here under the same verification rules as every other profile.
