# The MCP Illusion

## Definition

The misconception that wrapping existing human-centric APIs in the [[entity-mcp-d20]] makes them truly agent-native.

## The Critique

MCP is currently popular as a way to make tools 'agent-readable and writable.' However, it often serves as a superficial band-aid over fundamentally human-centric infrastructure. Developers assume that by sticking an MCP layer on top of a human-friendly API, the agent will 'make do.'

While agents are flexible enough to navigate this, it forces them to eat massive amounts of 'wall clock time' dealing with human affordances hidden behind the MCP. For example:

- An agent using an MCP for Salesforce still has to paginate records 100 at a time
- This pagination is a [[concept-human-affordance-bottleneck]] built for human screens and human memory
- Agents capable of ingesting millions of rows instantly are throttled by it

## Why This Matters

Relying on MCP to bridge the gap blinds developers to the deeper architectural rebuild required to achieve true agentic speed. The illusion is that interoperability has been achieved, when in fact only the surface has been translated.

This is the core argument of the contrarian position [[contrarian-mcp-is-not-enough]].

## Validation

Supported as critique. Protocols like MCP risk masking bottlenecks (tool-choice errors, pagination, instruction drift); benchmarks miss real agent behaviors like wrong-tool selection or context drift.
