Open source trail
Content changes are reviewable
Listing files and their history live in the public content repository. The website implementation is maintained in a separate public repository.
About the directory
A public directory with an evidence-based inclusion test
agentfirst.directory documents products, infrastructure, and protocols that give AI agents a material role or capability. It is a discovery resource. It is not a security certification, product endorsement, or complete census of the market.
Publisher
Published by Brad Vincent
I publish and maintain agentfirst.directory. You can find me on GitHub as Brad Vincent (@bradvin) and on X as @bradvin. Community members can propose additions and corrections through the public content repository. Publication decisions remain subject to the same evidence-based inclusion policy.
Editorial boundary
Inclusion is not a recommendation
A listing means public evidence supports one agent-first classification. It does not mean the directory has tested the product or verified its security, reliability, pricing, legal terms, or suitability for a task.
Corrections
Claims can be challenged
Readers, vendors, and contributors can open a public issue with a specific claim and supporting source. See the corrections policy for the review process.
Purpose
Why the directory uses a stricter definition
Almost any API can be called by an agent. That alone does not make a product agent-first. The directory checks what the agent actually does, whether that role is material, and whether a maintained first-party source supports the claim. That keeps the taxonomy useful without excluding infrastructure agents depend on.
Reuse and attribution
Public access does not grant a separate data licence
No separate open licence currently grants bulk republication of the directory's editorial copy or compiled data. The public repositories and live JSON/CSV exports make the work inspectable and citable; they do not by themselves change its reuse rights. Linking to pages and short attributed quotations are welcome. Product names, logos, documentation, and other vendor materials remain subject to their owners' terms. Any future immutable dataset release will publish explicit reuse terms alongside the download.
