The Fragmented World of AI Developer Tooling
Since OpenAI introduced function calling in 2023, developers have grappled with a critical challenge: enabling AI agents to seamlessly interact with external tools, data, and APIs. While foundational models grow smarter, integrating agents into diverse systems remains cumbersome, requiring custom logic for every new integration.
Enter Model Context Protocol (MCP)—a breakthrough standard introduced in November 2024 that’s rapidly gaining traction as the glue connecting AI agents to the tools they need. In this blog, we explore how MCP is reshaping AI workflows, its current applications, and the challenges that could define its future.
What is MCP?
MCP is an open protocol that standardizes how AI models fetch data, call tools, and interact with services. Inspired by the Language Server Protocol (LSP)—which unified code editors and language tools—MCP takes a leap forward by enabling autonomous, agent-driven workflows.
Key Innovations:
- Agent-Centric Execution: Unlike LSP’s reactive design (e.g., autocomplete suggestions), MCP lets AI agents proactively chain tools, APIs, and data to achieve tasks.
- Human-in-the-Loop: Built-in support for human oversight, allowing users to approve actions or inject context mid-workflow.
- Generalizable Context: Systems describe their capabilities in a standardized format, letting agents adapt to new tools without custom code.
For example, the Resend MCP server enables any MCP-compatible client (like a code editor) to send emails by translating natural language requests into API calls.
How MCP is Being Used Today
1. Dev-Centric Workflows: “Never Leave Your IDE”
Developers are using MCP to turn tools like Cursor (a code editor) into Swiss Army knives for productivity:
- Database Management: Query Postgres or manage Upstash caches without switching tabs.
- Real-Time Debugging: Integrate the Browsertools MCP to give agents access to browser consoles and logs.
- Instant Integrations: Auto-generate MCP servers from API docs, letting agents use tools like Slack or Stripe without manual setup.
2. Net-New Consumer Experiences
Non-technical users are also benefiting:
- Claude Desktop: A user-friendly MCP client for tasks like drafting emails or generating images via Replicate’s MCP server.
- Text-to-3D Workflows: Amateur designers use natural language to build Blender models via the Blender MCP server.
- Cross-App Pipelines: Apps like Highlight use the
@
command to invoke MCP servers, piping outputs between tools (e.g., generating text in Notion and sending it to Slack).
The MCP Ecosystem: Progress and Gaps
Key Players:
- Marketplaces: Mintlify’s mcpt, Smithery, and OpenTools (think “npm for MCP servers”).
- Infrastructure: Cloudflare and Smithery for server hosting; Toolbase for key management.
- Codegen Tools: Mintlify and Speakeasy auto-generate MCP servers from APIs.
Critical Gaps:
- Server Discoverability: Finding and configuring servers is manual. (Anthropic hinted at a registry solution soon. Anthropic hinted registry)
- Fragmented Clients: Most clients (like Cursor) cater to developers. Business-focused tools are scarce.
- Local-First Bias: Most servers run locally, limiting scalability.
Challenges to Solve
1. Authentication & Authorization
- No Standard Auth: MCP lacks built-in mechanisms for OAuth or API tokens, forcing developers to roll their own.
- Session-Based Permissions: Tools are either fully accessible or blocked—no granular controls.
2. Multi-Tenancy & Hosting
- Scalability: Enterprises need shared, secure servers. Remote hosting and data/control plane separation are unsolved.
- Execution Guarantees: Agents need retries, resumability, and stateful workflows—currently patched with tools like Inngest.
3. Client Experience
- UI/UX Chaos: Clients use everything from slash commands to natural language for tool invocation.
- Debugging Nightmares: Server developers struggle with inconsistent client behaviours and missing traces.
The Future of MCP: Predictions
- Tool Discovery Wars: Companies will compete to make their tools “agent-friendly,” optimizing for machine preferences (cost, speed) over human UX.
- Documentation as Infrastructure: APIs will ship with machine-readable
llms.txt
files, auto-generating MCP servers. - New Pricing Models: Agents might dynamically select tools based on real-time cost-performance tradeoffs.
- Specialized Hosting: Infrastructure optimized for multi-step AI workflows (long-running tasks, real-time load balancing).
Conclusion: A Protocol for the Agent-First Era
MCP isn’t just another API standard—it’s a paradigm shift. By giving AI agents a universal language to interact with tools, it unlocks autonomous workflows that were previously siloed or manual. While challenges like authentication and scalability loom, the protocol’s momentum is undeniable.
As Collabnix puts it: “MCP could become the TCP/IP of AI tooling—the invisible backbone powering a new era of intelligent applications.”
