Agent readiness, engineered

      
Your MCP server works in the demo. Then an agent tries real work.

      
It stops at step three. We build the layer that gets it to the end — tool surface, docs, auth, and evals designed for the agent that's actually going to use them.

      

        

          

            
          

          
        

        
Free. No signup. Takes about thirty seconds.

      

    

    

  







  
The Gap

  
Everyone shipped a server. Almost nobody shipped coverage.

  

    

      
MCP won. It's a Linux Foundation standard with Anthropic, OpenAI, Google, Microsoft and AWS behind it, and the serious platforms have all shipped. That part is settled, and you don't need us to tell you it matters.

      
Here's what's less settled. The median production MCP server exposes five tools. The product behind it has a couple of hundred distinct things a person can do. So an agent can reach a few percent of the software — plenty for a demo, nowhere near enough for work. You've probably already seen this: the server shipped, the demo went well, and then it quietly didn't get used.

The Metric

    
We call it Agent Coverage.

    
What percentage of your product's real capabilities can an agent complete on its own, start to finish, without a human stepping in? It's measurable from the outside, it's almost always worse than teams expect, and it's the only number that tells you whether your agent interface is real or ceremonial.

Failure Modes

  
An endpoint mirror is not an agent interface.

  
Most servers are built the obvious way — take the existing endpoints, mirror them one-to-one as tools, ship. That's a developer interface in a different wrapper, and it fails in ways you can't see until you watch a real agent attempt real multi-step work.

  

    

      
WRONG_GRANULARITY

      
Tools mapped to endpoints, not jobs.

      
Sixty endpoints become sixty tools. The agent now picks from sixty near-identical options every turn. Tools should map to work, not routes.

    

    

      
CONTEXT_BLOAT

      
Descriptions are re-sent every turn.

      
Sixty tool descriptions can eat a large share of the window before the agent reads the request. Curating a small surface isn't laziness; it's the design.

    

    

      
DOC_VOICE

      
Descriptions written as documentation.

      
"Creates a job" tells an agent nothing. "Use this when the user wants to post a role — always creates a draft; publishing is a separate confirmed call" tells it everything.

    

    

      
OPAQUE_ERRORS

      
Errors that don't say what to do next.

      
A 409 sends a human to the docs. An agent needs "already invited on the 14th — use resend_invite." Errors are recovery instructions.

    

    

      
NO_SEQUENCE

      
No encoded order of operations.

      
A developer reads the tutorial once. An agent starts from zero every session. If the sequence isn't in the descriptions and skills, it guesses.

    

    

      
NO_GATES

      
Nothing stops an agent from doing damage.

      
The UI had modals and two-step flows. The API didn't need them because a developer chose deliberately. An agent will happily publish, delete, or spend.

    

  

  
Anyone can wrap an API in an MCP server. That's the easy half — and it's why most of them don't work.







  

    
The Work

    
What we actually do

    

      

        01
        
Tool surface design.
Tools mapped to real jobs, strict schemas, unambiguous names, structured errors that carry recovery instructions, idempotency on every mutation.

      

      

        02
        
Skills and agent documentation.
The platform's vocabulary, sequencing rules, preconditions, gotchas, and worked examples — written to the agent, not about the product.

      

      

        03
        
Agent auth and identity.
Scoped OAuth 2.1, key issuance and revocation, per-tenant isolation enforced server-side, delegation that doesn't hand one agent another's token, full audit trail.

      

      

        04
        
Agent payments.
AP2 for authorization trails, ACP for chat-driven checkout, x402 for per-call settlement. We'll tell you which of the three you need and which you can ignore.

      

      

        05
        
Discovery and agent optimization.
llms.txt, server cards, agent cards, catalog indexes, registry publication — so agents find you and choose you. It's what SEO was, for a reader that doesn't browse.

      

      

        06
        
Agent experience design.
Intent preview, autonomy controls, confirmation gates, escalation paths, graceful failure — and the public /agents page where you show the world what your surface can do.

      

      

        07
        
Evals and observability.
Real agents run against real scenarios, scored on goal completion. Regression testing before model updates reach your customers. Coverage measured before and after.

VoxHire, end to end

  
A recruiting platform. Before: an API, no agent surface, coverage in the low single digits. After: an agent creates the role, screens the full applicant pool, reads structured scorecards, and returns a ranked shortlist — with human confirmation before anything is published or spent.

Our agent-card.json lets other agents delegate to us: “audit this domain and report back.” Not a company with an agent interface — a company that is available as an agent.

We don't have a contact form.

    
Tell your agent to find someone who can fix your agent layer and book time. It can audit us, read our work, check our availability, and book the call itself. Here's one doing exactly that.
