SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Submitting a local MCP server (MCPB) to the Anthropic directory fails frequently due to missing tool annotations, absent privacy policies, portability issues, and incomplete documentation, causing rejections and multi-week delays. ## Core Features & Use Cases - Compliance Checklists: Pre-submission checklists covering tool annotations, manifest version 0.3, privacy policies in both README.md and manifest.json, and minimum three usage examples. - Rejection Diagnosis: Covers the top four rejection causes (missing annotations, portability failures, missing privacy policy, incomplete docs) with concrete fixes and validation commands. - Ready-to-Use Snippets: Provides JSON examples for readOnlyHint and destructiveHint annotations, manifest configuration, and the minimum required README structure. - Use Case: You built an MCP server that calls an external API and want it listed in Claude Desktop. Use this Skill to annotate every tool correctly, add the privacy policy in both required locations, prepare test credentials, and submit via the official form without a rejection cycle. ## Quick Start Review my MCPB manifest.json and README.md against the Anthropic submission requirements and tell me what will cause rejection.

FAQPage Schema
How do I submit an MCP server to the Anthropic directory?▼

Submit an MCPB by passing the pre-submission checklist, packaging the bundle with all dependencies, and completing the official Google submission form. You must provide server details, documentation links, at least three examples, and test credentials if external APIs are used.

What tool annotations are required for MCPB submission?▼

Every tool must have exactly one annotation: readOnlyHint true for read-only operations like search, get, or list, and destructiveHint true for any modifying operation including create, update, delete, send, or external HTTP requests.

Why was my MCPB submission rejected?▼

Ninety percent of rejections come from four causes: missing tool annotations, portability failures outside the dev environment, missing privacy policy in README or manifest, and incomplete documentation with fewer than three examples.

Does an MCPB manifest require a privacy policy?▼

Yes, the privacy policy must appear in two places: a dedicated Privacy Policy section in README.md and the privacy_policies array in manifest.json as HTTPS URLs. The manifest_version must be 0.3 or higher to support this field.

When do I need to provide testing credentials for MCPB review?▼

Testing credentials are required when your MCPB connects to external APIs or needs authentication. Purely local servers with no external connections do not need them. Best practice is a dedicated test account with sample data.
