Overview

MCP Server Builder gives teams a structured way to draft tool definitions, resources, test payloads, and manifest notes before wiring an agent to real systems. It should make launch readiness visible without requiring a backend in the first prototype.

How it works

1Define server purposeName the server, primary agent job, and first tool contract.Local

2Build manifest previewGenerate tool schema, resources, and representative test payloads.Manifest

3Review agent metadataCheck action names, explicit fields, auth notes, limits, and failure states.Review

4Test and packageHand off to MCP Tester, docs export, and workflow launch approval.Handoff

Security and launch review

Local draftManifest generation should not send private tool descriptions to a cloud service.

AuthProduction launch must capture OAuth, API key, tenant, and rate-limit policy notes.

AuditTeam review should record schema changes, test payloads, and reviewer approval state.
