HIGHLIGHTS
5x MCPs with multiple shipped per week
95% token reduction using MCP
Venn. self-service commercial product
What Was Barndoor's Challenge?
Barndoor helps enterprises use AI safely. They provide governance policies and access controls for AI agents connecting to third-party services like Salesforce, Slack, and Google Drive.
In mid-2025, they hit a classic chicken-and-egg problem. AI governance only matters if there's something to govern. But the MCP ecosystem was thin, and Barndoor had only a few prototypes.
Customers kept asking the same question: "What exactly am I governing?" MCP was still new and Barndoor knew they had to deliver both the security and enablement layer.
They had a core engineering team but weren't ready to hire another squad of AI engineers. Hiring is slow and expensive, and they needed momentum they could trust.
The Solution
Moda Labs came in as a second execution team, embedded with Barndoor rather than operating at arm's length. With hands-on founders (a PM and an engineer) plus four engineers across frontend and backend, Moda delivered a shovel-ready team already fluent in AI.
Phase 1: MCP Factory (Aug–Sept 2025)
The first priority was scaling the integration library.
We built a repeatable system for spinning up MCPs: code patterns that leverage OpenAPI specs, a testing framework that catches problems early, and support for remote-hosted MCPs like Notion's official server.
Within weeks, we were shipping 2-3 new integrations per week. By late September, Barndoor's library had grown 5x and continued to scale into 2026.
Phase 2: ToolIQ (Oct–Nov 2025)
Scaling the library exposed a deeper problem with context limitations.
Through dogfooding, we found that loading just 2-3 MCP servers would fill the entire 200k token context window. Pulling 3-5 emails in a single response caused the same overflow. This wasn't a known issue yet — Anthropic wouldn't publish their progressive disclosure approach until November. We were looking at a constraint the market hadn't caught up to.
Phase 3: Venn (Dec 2025–Feb 2026)
In November, three months into the engagement, Barndoor needed to quickly productize their MCP work. Instead of moving slowly with hiring and recruiting, they chose to work with Moda, a team that quickly earned their trust with consistent execution and strong expertise.
They extended the contract. We spent three more months turning the infrastructure into Venn: a self-service product aimed at end users that launched in February 2026.
What started as platform acceleration had become a new revenue stream.
Impact
So we built the fix:
Single entry point for all MCPs. Rather than configuring MCP servers fresh with every chat session, we created a tool router that lets users configure once and use everywhere, giving access to all their MCPs from a single place.
Progressive disclosure for tools. Instead of loading every tool definition upfront, we search by name first (minimal tokens), then describe only the tools the agent needs. Token usage dropped from 160k to 7k in preliminary tests.
Code execution for responses. Raw API responses are bloated with formatting. We run code to parse and strip responses before anything hits the context window. Loading emails went from consuming 20k tokens to a few hundred.
We called it ToolIQ and shipped it in December, with an eval system to test across all the MCP servers.
Before Moda Labs:
A few MCP integrations prototypes
Engineering team stretched between core product and MCP library
Barndoor needed to deliver on a broader integration story
After Moda Labs:
5x MCP integrations with several new MCPs shipping per week
95% reduction in token usage across tool use
New commercial product launched Feb 2026
Looking Under the Hood
Project Setup
Team: Moda Labs founders (Product, Engineering), 2 onshore, 2 offshore engineers
MCP System: Agentic MCP builds from OpenAPI specs that handles OAuth and API key authentication, and automate tool management so integrations stay updated
Models: Claude and ChatGPT for agent orchestration and tool calling; Claude Code for agentic development workflows
Tool Router: Common routing gateway with progressive disclosure and code execution
Eval System: Automated agent evaluation pipeline built on LangGraph, OpenTelemetry, and Arize
The system has three layers:
MCP Factory: Generates tool definitions from OpenAPI specs, packages them as MCP servers, and runs automated tests for quality
Tool Router (ToolIQ): Sits between the agent and MCP servers. Handles tool search, progressive disclosure, and response parsing. The agent only sees what's relevant to the current task.
Venn: Web application where users configure their MCPs, connect to their services, and manage access controls in one place.
Why This Worked
AI depth, not just engineering capacity. Barndoor's team had engineers, but they were stretched thin. They needed a trusted partner who could spot problems before customers hit them and build solutions the market hadn't seen yet. Moda Labs brought a full squad with the intuition to move fast and the experience to know what to build.
Long-term partnership, not a quick project. The original scope was MCP scaling. But because we were embedded, working alongside Barndoor's team and using what we built, we surfaced the token problem before it became a crisis. When they saw the opportunity for Venn, we extended the partnership to build it together.
What's Next
Barndoor now has two levers: their core governance platform and Venn, both running on a single stable foundation. Moda Labs continues the partnership, building skills and memory into ToolIQ while maintaining the MCP factory.
The engagement started as platform acceleration, then became a new product line.
