vellum MCP advocates for resource-based context management

By PulseAugur Editorial · [1 sources] ·

The author advocates for a design choice in MCP servers, differentiating between 'tools' for actions and 'resources' for reading to optimize context window usage. This approach, implemented in vellum MCP, exposes notes as resources accessible via stable URIs, allowing agents to reference documents by name rather than through costly tool calls. This design aims for a more efficient and lightweight server architecture, with vellum MCP being a self-hostable, 24MB container. AI

IMPACT Optimizes agent context window usage by distinguishing between actionable tools and readable resources, potentially improving efficiency in AI applications.

RANK_REASON The item discusses a specific implementation detail and design philosophy for a self-hostable server (vellum MCP) that uses the MCP protocol, which falls under tooling for AI development.

    Resources for reading, tools for acting: the MCP design choice most servers get wrong

    <p>Every tool you expose over MCP ships its full definition (name, description, JSON schema) into the model's context on <strong>every single request</strong>, whether that tool ever gets called or not. Expose twenty tools and the agent wades through pages of boilerplate before i…
