OpenCoverage MCP server has 12 tools with complete input schemas and descriptions. Naming follows verb_noun convention (list_, get_, ingest_). However, descriptions are brief (10-50 chars) and lack context on WHEN to use each tool or dependencies between them. Parameter descriptions are present but minimal. Output schemas are not documented, LLMs cannot predict response structure for chaining. Error handling is basic; no recovery guidance. Two write tools (ingest_coverage_run, ingest_integration_run) lack confirmation/dry-run patterns. Overall: functional but below production baseline for agent reasoning.

• Document output schemas for all 12 tools. Example: 'Returns {projects: [{id, name, group, defaultBranch, createdAt}], total, page, pageSize}'. This enables LLMs to chain tools correctly.
• Expand tool descriptions to 80-150 characters. Add WHEN to use: 'List all projects to discover available coverage data. Call this first if you don't know the project ID. Returns paginated results; use page/pageSize for large datasets.'
• Add dry-run parameter to ingest_coverage_run and ingest_integration_run: 'dry_run (boolean, optional): If true, validate payload without persisting. Useful for testing before real ingestion.'
• Enhance parameter descriptions with constraints and examples. E.g., 'from (string, optional): RFC3339 timestamp (e.g., 2024-01-15T10:30:00Z). Filters runs after this time. Must be before 'to' if both provided.'
• Add error handling guidance to ingest tools. E.g., 'On validation error, returns {error, invalidFields: [{field, reason}]}. Agent should ask user to correct and retry. On network error, safe to retry.'
