MCP's ecosystem, while growing rapidly, is still evolving:

• Limited Support: Not all AI platforms or LLM providers fully support MCP yet
• Potential Fragmentation: Risk of competing standards or plugin frameworks
• Connector Availability: May need to implement missing connectors for some services
• Version Changes: Possible breaking changes as the specification evolves

Adoption Landscape

• Strong Support: Anthropic's Claude and various agent frameworks
• Limited Support: OpenAI models don't natively speak MCP (though experimental SDKs exist)
• Growing Momentum: Many see MCP as a neutral, model-agnostic solution

Adopting MCP early means accepting some uncertainty, but the standard shows strong promise for becoming the dominant approach to AI tool integration.
