MCP servers & API integrations

So agents and workflows can reach your backend, a third-party system, or a legacy database.

The work

What this actually involves

Connecting an API is the easy part. The work is what holds it up: authentication that survives a token rotation, retries that do not duplicate writes, and a reconciliation step for when two sources disagree.

I build MCP servers so AI agents can use your systems as tools, and ordinary integrations for everything that does not need an agent.

Included

What you get

01

MCP servers

Your systems exposed as tools an agent can call, with scoped permissions and structured returns.

02

v1 to v2 OAuth2

Migrations carried out without interrupting accounts that are live and billing.

03

Middleware

The bit between two systems that neither vendor will own: queues, transforms, retries, dead letters.

04

Reconciliation

When sources conflict, the conflict is surfaced rather than silently resolved.

Hire me when

Signals this is the right piece of work

01

An AI agent needs to reach a system that has no integration

02

You are moving from the v1 API to v2 OAuth2 and cannot afford downtime

03

Two systems drift out of sync and nobody can explain which one is right

04

A legacy database holds the data the rest of the stack needs

05

Webhooks fire twice, or stop firing, and the failure is silent

06

You need the integration documented so it is not a black box after handover

A written architecture record and a staged plan, useful whether or not I build the rest.
