Software program builders spend most of their time not writing code; latest business analysis discovered that precise coding accounts for as little as 16% of developers’ working hours, with the remaining consumed by operational and supportive duties. As engineering groups are pressured to “do extra with much less” and CEOs are bragging about how a lot of their codebase is written by AI, a query stays: What’s executed to optimize the remaining 84% of the duties that engineers are engaged on?
Hold builders the place they’re the best
A serious wrongdoer to developer productiveness is context switching: The fixed hopping between the ever-growing array of instruments and platforms wanted to construct and ship software program. A Harvard Enterprise Evaluation research discovered that the common digital employee flips between functions and web sites almost 1,200 times per day. And each interruption issues. The College of California discovered that it takes about 23 minutes to regain focus after a single interruption totally, and typically worse, as almost 30% of interrupted tasks are never resumed. Context switching is definitely on the heart of DORA, probably the most common efficiency software program improvement frameworks.
In an period the place AI-driven firms try to empower their workers to do extra with much less, past “simply” giving them entry to large language models (LLMs), some traits are rising. For instance, Jarrod Ruhland, principal engineer at Brex, hypothesizes that “builders ship their highest worth when targeted inside their built-in improvement surroundings (IDE)”. With that in thoughts, he determined to seek out new methods to make this occur, and Anthropic’s new protocol could be one of many keys.
MCP: A protocol to carry context to IDEs
Coding assistants, reminiscent of LLM-powered IDEs like Cursor, Copilot and Windsurf, are on the heart of a developer renaissance. Their adoption pace is unseen. Cursor turned the fastest-growing SaaS in historical past, reaching $100 million ARR inside 12 months of launch, and 70% of Fortune 500 firms use Microsoft Copilot.
AI Scaling Hits Its Limits

However these coding assistants had been solely restricted to codebase context, which may assist builders write code sooner, however couldn’t assist with context switching. A brand new protocol is addressing this subject: Model Context Protocol (MCP). Launched in November 2024 by Anthropic, it’s an open commonplace developed to facilitate integration between AI methods, notably LLM-based instruments, and exterior instruments and knowledge sources. The protocol is so common that there was a 500% increase of latest MCP servers within the final 6 months, with an estimated 7 million downloads in June,
One of the crucial impactful functions of MCP is its potential to attach AI coding assistants on to the instruments builders depend on on daily basis, streamlining workflows and dramatically decreasing context switching.
Take function improvement for example. Historically, it entails bouncing between a number of methods: Studying the ticket in a challenge tracker, taking a look at a dialog with a teammate for clarification, looking documentation for API particulars and, lastly, opening the IDE to start out coding. Every step lives in a special tab, requiring psychological shifts that gradual builders down.
With MCP and trendy AI assistants like Anthropic’s Claude, that total course of can occur contained in the editor.
For instance, implementing a function all inside a coding assistant turns into:
The identical precept can apply to many different engineers workflow, for example an incident response for SREs may appear like:
Nothing new underneath the solar
We’ve seen this sample earlier than. Over the previous decade, Slack has remodeled office productiveness by changing into a hub for tons of of apps, enabling workers to handle a variety of duties with out leaving the chat window. Slack’s platform lowered context switching in on a regular basis workflows.
Riot Video games, for instance, related round 1,000 Slack apps, and engineers noticed a 27% reduction in time wanted to check and iterate code, a 22% sooner time to establish new bugs and a 24% improve in function launch charge; all had been attributed to streamlining workflows and decreasing the friction of tool-switching.
Now, an identical transformation is happening in software program improvement, with AI assistants and their MCP integrations serving because the bridge to all these exterior instruments. In impact, the IDE may grow to be the brand new all-in-one command heart for engineers, very like Slack has been for basic data employees.
MCP is probably not enterprise prepared
MCP is a comparatively nascent commonplace, for instance, safety wisem MCP has no built-in authentication or permission mannequin, counting on exterior implementations which are nonetheless evolving There’s additionally ambiguity round id and auditing — the protocol doesn’t clearly distinguish whether or not an motion was triggered by a consumer or the AI itself, making accountability and entry management tough with out further customized options. Lori MacVittie, distinguished engineer and chief evangelist in F5 Networks’ Workplace of the CTO, says that MCP is “breaking core safety assumptions that we’ve held for a very long time.”
One other sensible limitation arises when too many MCP instruments or servers are used concurrently, for instance, inside a coding assistant. Every MCP server advertises an inventory of instruments, with descriptions and parameters, that the AI mannequin wants to contemplate. Flooding the mannequin with dozens of obtainable instruments can overwhelm its context window. Efficiency degrades noticeably because the instrument rely grows with some IDE integrations have imposed laborious limits (round 40 instruments in Cursor IDE, or ~20 instruments for the OpenAI agent) to forestall the immediate from bloating past what the mannequin can deal with
Lastly, there is no such thing as a subtle method for instruments to be auto-discovered or contextually urged past itemizing all of them, so builders typically need to toggle them manually or curate which instruments are energetic to maintain issues working easily. Referring to that instance of Riot Video games putting in 1,000 Slack apps, we are able to see the way it could be unfit for enterprise utilization.
Much less swivel-chair, extra software program
The previous decade has taught us the worth of bringing work to the employee, from Slack channels that pipe in updates to “inbox zero” e mail methodologies and unified platform engineering dashboards. Now, with AI in our toolkit, we have now a possibility to empower builders to be extra productive. Suppose Slack turned the hub of enterprise communication.
In that case, coding assistants are well-positioned to grow to be the hub of software program creation, not simply the place code is written, however the place all of the context and collaborators coalesce. By retaining builders of their movement, we take away the fixed psychological gear-shifting that has plagued engineering productiveness.
For any group that will depend on software program supply, take a tough take a look at how your builders spend their day; you could be stunned by what you discover.
