MCP server development — proven on this site, not just pitched

See it work, right now

Point any MCP-capable client at https://tunovix.com/mcp (streamable-http transport) and call tools/list — it returns the real, current schema for all 24 tools: 8 are project-cost calculators, built with the exact same enumFromKeys() pattern that keeps a tool's inputs from drifting out of sync with the actual application code behind them; 12 are multi-turn interactive workflow walkthroughs (customer support, document processing, sales qualification, and nine more real patterns) that accept a followUp id to continue a conversation instead of replaying a single scripted response; one matches a described business problem to a real published use case; one runs the same content search the RAG search demo uses, over this site's own indexed content; one runs a real, live AI-discoverability audit of any URL you give it — the same audit behind the discoverability checker; and one fingerprints the WAF/CDN in front of any URL — the same check behind the WAF checker. There's also a structured resources/read endpoint on tunovix://agent-build-methodology for checking what a Tunovix-built agent's guardrails/evals/audit-logging setup actually includes. None of this is a demo environment — it's the live production endpoint. Full request/response examples: API reference.

What an MCP build for you looks like

The same pattern as the internal one above, pointed at your systems instead: read access to your documents or database, write access scoped to specific, narrow actions (never broad file/shell/deploy access), and a schema that's generated from your actual application logic where possible, not hand-typed and left to drift. See the internal knowledge agent use case for the shape of a typical build — Drive, Notion, Slack, a database, and internal APIs, all reachable through one MCP server.

Why this is more than a buzzword here

Real engineering write-ups exist because real MCP work happened, not the other way around: read about the 2026-07-28 spec revision that made MCP fully stateless and what it means running on Cloudflare Workers, or the gotchas hit wiring an MCP server, a signed Agent Card, and health checks into a production Worker — the kind of detail that only comes from having actually shipped it.

Cost and timeline

An MCP server exposing a handful of tools against your existing systems typically lands around $2,050–$4,350 and 3-4 weeks — see the full AI agent cost breakdown for how that compares to other agent types, or run the calculator with your real scope.
