MCP Protocol integration services — expose your APIs to AI tools
Ship MCP servers that let Claude Code, Cursor, and any MCP client call your data and actions. Proven at Instill.
Who this is for
AI-tooling company or internal platform team that wants to expose its data or actions to Claude, Claude Code, or other MCP clients.
The pain today
- MCP is new — most agencies have not shipped it.
- Docs and specs move weekly; nobody on the team tracks them.
- Existing APIs do not map cleanly to MCP tool schemas.
- Auth and schema discipline matter more than they do for regular REST.
The outcome you get
- A senior engineer who has shipped MCP in production at Instill.
- MCP servers mapping your existing APIs to MCP tools.
- Auth plus schema plus tool registration handled correctly.
- Client compatibility tested against Claude Code, Cursor, and the MCP Inspector.
What MCP integration services cover
MCP engagements cover: MCP server authoring (TypeScript SDK, tool registration, schema definitions, prompt templates where relevant), authentication (API keys, OAuth, or per-client tokens), resource handling (files, URLs, or dynamic data exposed as MCP resources), tool plus prompt plus resource surfaces designed for the actual agent use case (not a dump of your REST API), testing (MCP Inspector for manual validation, automated tests against the protocol), deploy (stdio for local MCP, HTTP for remote MCP), and client compatibility verification (Claude Code, Cursor, Zed, Windsurf, custom clients).
Instill — MCP shipped in production
Instill (SITE-FACTS §6) is the reference point. Next.js 16 plus React 19 plus TypeScript plus PostgreSQL plus Vercel plus MCP Protocol. 30+ active users, 1,000+ skills saved, 45+ projects powered. The MCP server exposes Instill skills (prompt templates, workflows, custom instructions) to any MCP client. A user saves a skill in Instill, opens Claude Code, and calls that skill by name. The open MCP standard means the skill library works across tools, not just in one.
MCP vs custom REST integration
MCP's value: every MCP-compatible client (Claude Code, Cursor, Zed, many more every month) can call your MCP server with zero per-client work. Build once, integrate everywhere. Custom REST integrations require per-client engineering (Claude Code has one integration pattern, Cursor has another, etc.). If your integration target is 'all AI tools', MCP wins. If your integration target is one specific client with a stable API, custom REST may still be cheaper short-term.
Pricing and scope
AI Automation retainer at $3,000 per month. 2 to 4 day delivery cycles. 14-day money-back. Cancel anytime. Typical MCP engagements run 3 to 8 weeks — a focused MCP server for one API domain, tested across multiple clients, documented for the in-house team.
Recent proof
A comparable engagement, delivered and documented.
A prompt library that works with every AI tool
A home for your best AI prompts. Save them once, then use them in Claude, Cursor, or any AI tool you work with. No more copy-paste.
Frequently asked questions
The questions prospects ask before they book.
- MCP TypeScript SDK or Python SDK?
- TypeScript when the rest of the stack is TypeScript (my default). Python when the backend is Python. Both SDKs are maintained by Anthropic and feature-comparable.
- stdio or HTTP transport?
- stdio for local MCP servers (Claude Code launching a local process). HTTP (streamable HTTP) for remote MCP servers accessed over the network. Most production MCP is HTTP with auth.
- Can you add MCP to an existing API?
- Yes. The MCP server wraps the existing API — I design the tool schemas to expose the right subset of your REST endpoints as MCP tools. Auth flows through.
- MCP auth?
- API key in headers for simple cases. OAuth for multi-tenant or end-user auth. Per-client credentials plus rate limiting when you expose to many clients.
- How do I test MCP compatibility?
- MCP Inspector (official tool) for manual validation. Automated tests against the MCP protocol spec. Real-client smoke tests against Claude Code and Cursor before launch.
