Agenda

The project's Antitrust Policy is linked from the LF and project websites. The policy is important when multiple companies, including potential industry competitors, are participating in meetings. Please review it, and if you have any questions, please contact your company’s legal counsel. Members of the LF may contact Andrew Updegrove at the firm Gesmer Updegrove LLP, which provides legal counsel to the LF.

API Design Guide Enhancements

Improve API Design Guidelines for MCP/Agent readiness · Issue #587 · camaraproject/Commonalities

  1. Good operationIds

  2. Decent Descriptions

@Ben Hepworth commented on observations that too verbose descriptions can be less effective for AI use.

@Rafal Artych indicated description templates can be used to have consistent operation description, for example:

description: |

When to use: {{ user asks to... }}

Differences: {{ Use instead of X when... }} (optional)

Side effects: {{ Action taken }} or "None"

Returns: {{ What’s in the response and how to use it }}

Requires: {{ Data needed, e.g. "customerId from context" }}

 

@Tanja De Groot (Nokia)asked about using Gherkin feature definitions for describing MCP tools.

Interesting article from FastMCP author: https://jlowin.dev/blog/as-an-agent-the-new-user-story

see MCP specs:

interface ToolAnnotations {
  title?: string;
  readOnlyHint?: boolean;
  destructiveHint?: boolean;
  idempotentHint?: boolean;
  openWorldHint?: boolean;
}
