The MCP server
This is the front door for agentic callers, so build it on purpose. Generated from the same OpenAPI spec as your SDK, in sync from the first commit.
What “agent experience” actually means
AX is the developer experience an AI agent needs to call your API and get it right. Five things move, and none of them are free.
Tool schemas agents can reason about
Names, descriptions, and parameter schemas an agent can read and act on. Most first attempts at an MCP server are useless to agents, because teams write the tool descriptions for humans skimming docs, not for a machine deciding what to call.
Error semantics that fail safely
An agent does not read errors the way you do. A vague 500 gets retried forever. A 429 with no Retry-After retries at the wrong rate. The error surface needs more care here, not less.
Rate limits for autonomous traffic
Agent traffic is bursty, repetitive, and prone to tight retry loops. You tuned your rate limits and dashboards for human-driven clients, not for this.
Safety guardrails
Some operations have no business running without a human saying yes first. Deciding which tools need approval, and tagging them, is real work, not a checkbox.
Why this matters now
Here is the shift that happened across 2025 and 2026. Most new integration partners for an API-first SaaS are now agents, or tools driven by agents, not people writing integration code by hand.
You usually find this out when a partner asks “do you have an MCP server?” and you have 48 hours to ship something that does not fall over in front of them. You can have a calm six-week build or a 48-hour scramble. Pick one knowingly. We would rather help you build the right thing.
How we engage
Four shapes the work tends to take. Most of them start with one 30-minute call.
MCP foundation sprint
Fixed-price, 4 to 6 weeks
We ship your first MCP server end to end. Tool schemas designed and reviewed. Error semantics that fail safely. Tested against Claude, ChatGPT, and Cursor before you hand it to a customer.
AX audit
Fixed-price, 2 weeks
You have an MCP server, or you are about to. We test it against the major agentic clients, score it, write up what breaks, and walk you through every finding.
AX retainer
Monthly
For teams whose product is moving in the agentic direction and means it. Tool schema reviews, customer escalations where an agent failed, roadmap reviews.
Joint DX + AX engagement
Fixed-price or retainer
One spec drives both the SDK and the MCP server. The work overlaps, so we often scope them together.
When Agent Experience is the right call
When yes
- A partner has asked about MCP and you are not sure what to ship.
- Your customers are starting to build agentic features, and the agent-readiness questions are landing in your inbox.
- You shipped an MCP server in a hurry and you can feel it is bad. Agents stall, fail in ways you cannot predict, or call the wrong tool.
- You are early in the API roadmap and want agent-readiness designed in, not bolted on later.
When no
- Your customers are not building agentic features and no partner is asking about MCP. You have time. Watch the space, and come back when it is real for you.
Honest about category maturity
Let us not oversell this. AX as a named practice is barely two years old. The standards are still settling. MCP looks like the protocol the industry is converging on, but it is young, and most API-first SaaS still react instead of plan.
Here is our bet. The teams that get this right in 2026 spend the next five years being the API agents reach for first. We are wagering the practice on it. If your team is nearer the front of that curve than the back, hire us. If you are further back, bookmark this page and come back when it is real for you.
