Sarah Simionescu, a member of technical staff at Composio responsible for the company's dashboard product, presented a seemingly contradictory argument at the 2026 AI Engineer World's Fair: dashboards are dead. This claim stems from her personal experience—despite using Datadog daily for six months, she froze when asked to navigate its dashboard to view an alert. This disconnect between daily usage and interface familiarity reveals the rise of agents as a new interaction layer.
Simionescu contextualizes this shift historically. In 2022, resolving a Slack error report required traversing five tools and five query languages, each serving as a translation device between user intent and data. The 2023 'sparkle button' attempted to use LLMs to generate queries but offered limited reliability and still required dashboard access. Anthropic's release of the MCP protocol in 2024 allowed agents to connect directly to services and execute queries, yet this did not solve the fundamental problem.
The core thesis is that MCP itself is insufficient for effective agent workflows. Simionescu identifies three specific failure modes: first, agents do not learn, starting every conversation from zero and repeating yesterday's formatting mistakes today; second, connecting multiple MCP servers dumps thousands of tool definitions (such as Composio's GitHub toolkit with over 200 tools) into the context window, causing models to select wrong tools or struggle with call ordering; third, each MCP server describes only its own app, leaving cross-app tasks requiring manual stitching of steps.
To address these issues, Simionescu presents Composio's solution: an interface designed specifically for agents. In a debugging demo, Claude calls Composio Search to state goals, and the system returns not only relevant tools but also a plan for using them, explicitly noting that finding a Slack channel ID is a prerequisite before querying messages. This explicit exposure of dependencies solves the problem of blind agent trial-and-error.
In a cross-app analytics demo, Simionescu shows how to handle large-scale information without loading complete data into the model's context. Claude queries PostHog for e-commerce user IDs and saves the results, then inspects the Metabase database schema, and finally uses Composio Remote Workbench to dynamically generate SQL with a regex string to match the saved user IDs. This mechanism separates the information needed for planning from the bulk data needed for execution.
Simionescu acknowledges that comparison data against native MCP servers is unreleased, so no quantified advantage can be proven. However, she emphasizes that designing products for agents means going beyond website SEO or adding AI buttons; it requires making operations discoverable, clarifying dependencies, and enabling data flow across apps. For developers building agent-facing products, the key challenge has shifted from human usability to machine understandability and composability.
