MCP Server Engineering

A production MCP server for your product, designed and built by senior US engineers, delivered with the security evidence your enterprise customers will ask for. The goal is not "we have an MCP server." The goal is a server that passes the customer's review the first time, gets listed in the connector directories that matter to your buyers, and does not have to be rebuilt in a year.

What we do

Tool design grounded in use cases. We start from what your customers' agents will actually be asked to do, not from a one-to-one wrap of every API endpoint. Typical servers ship with 8-20 tools, each with a narrow purpose, explicit read/write classification, and confirmation semantics for anything destructive.

Authorization that matches the specification. OAuth 2.1 with PKCE, protected resource metadata, authorization server metadata, and resource indicators. Either your existing identity provider is wired in as the authorization server, or we build a conformant bridge in front of it. No API keys pasted into a config file.

Per-user, per-tenant scoping enforced by the server. Every tool call resolves to a specific human in a specific tenant, and your data layer sees that identity. The agent can do what that person could do in your UI, and nothing more.

Audit events for every tool call. Structured, consistently shaped, with the user, tenant, tool, inputs summary, outcome, and timing. Exportable to a customer's SIEM in the formats they ask for.

Deployment in your cloud. Infrastructure as code, secrets in your secret manager, health checks, rate limits, and a runbook your on-call engineers can follow.

A security evidence pack. Threat model, data-flow diagram, control matrix mapped to the questions in common vendor questionnaires, and a short written answer for each. This is the document that turns a six-month review into a two-week one.

Directory submission. The listing package for the connector directories you name, with the review requirements already met.

Who this is for

• B2B SaaS companies with a public API and enterprise or mid-market customers who run vendor security reviews
• Teams whose first MCP server was a prototype that a customer's security team sent back
• Companies that need to be present in a connector directory and have been told what the listing requires

How we work with you

The work is billed hourly, time and materials, with scope and staffing agreed in an initial conversation. A typical build runs about six weeks: a design week (use cases, tool inventory, permission model, identity integration plan, threat model draft), three build weeks with a working demo against a real client every week, a hardening week of adversarial and abuse testing, and a final week for deployment, handover, and directory submission. That shape assumes a typical SaaS API and an existing OAuth-capable identity provider; if your API cannot express the permission model agents need, you hear it in the first week, not the fifth.

What it is not

• Not a change to your core product API. We work with what your API can already do and tell you plainly where it falls short.
• Not hosting. It runs in your account.
• Not an agent or a chat interface. We build what agents connect to.
