Structured tool discovery
UseAgents acts as a real-time registry where agents query structured tool data instead of searching or scraping documentation.
UseAgents
UseAgents is a real-time MCP registry that lets AI agents query structured tool data instead of scraping docs. It helps tool creators publish current usage details and helps agent builders choose and use tools with up-to-date context.
Overview
UseAgents is a real-time MCP registry for AI agents and tool creators. It is designed to replace ad hoc tool discovery through scraped docs, search results, or outdated model knowledge with structured tool data that agents can query directly.
On the homepage, agents ask for a tool in plain language, UseAgents returns structured context, and the agent proceeds with the right install or usage information. The product is positioned for both tool creators who want their tools discoverable and agent builders who need current implementation details before they write code or call an API.
What UseAgents provides
Capability-based search
Agents can search by what they need in plain language and receive ranked tool results from the registry.
Tool context retrieval
The response shown on the homepage includes install commands, usage shape, and auth requirements so agents can act with current context.
Creator-managed tool data
Tool creators can publish install steps, usage patterns, and metadata that agents need to use a tool correctly.
MCP workflow support
The registry is positioned as an MCP-connected system, with the agent querying the registry before execution.
Usage analytics
The pricing page says the product includes analytics on agent usage during the public beta.
Where UseAgents fits
Agent tool selection
A developer is building an agent that needs to choose and install a tool for a task such as authentication, billing, or logging. UseAgents provides current tool context instead of leaving the model to guess from training data.
Publishing a tool for agents
A tool creator wants new products to be discoverable by agents that increasingly make implementation decisions. Publishing to UseAgents gives the agent a structured source of truth for that tool.
Avoiding stale discovery
An agent builder wants to reduce failures caused by stale docs, conflicting search results, or outdated model memory. The registry returns a direct answer with implementation details before code is written.
Monitoring agent usage
A team needs visibility into how agents are using its tools during the beta period. The pricing page states that analytics on agent usage are included.
Pros and Cons
Pros
- Gives agents structured, current tool context instead of depending on scraped pages or model memory.
- Supports both sides of the workflow: creators publish tool data and agents retrieve it.
- The homepage shows agents can receive install commands, usage shape, and auth requirements in one response.
- The pricing page says the beta includes unlimited tool registration and unlimited MCP queries for agents.
- The product includes analytics on agent usage during the public beta.
Cons
- The source does not show detailed public docs for registration, deployment, or setup steps.
- The product is currently described as free during public beta, so long-term pricing is not yet defined in the source.
- The public pages provide only partial integration specifics beyond MCP-connected workflows and structured queries.

Why should I add my tool to UseAgents?
Tool creators publish the source of truth in UseAgents so agents can query current, structured tool data instead of relying on scraped docs or model memory.
How do I get started?
The pricing page and homepage show a sign-in flow and public beta access, but the source text does not provide detailed setup steps for publishing or connecting a tool.
