MCP server for Atlassian Jira and Confluence with schema-validated Markdown↔ADF conversion. Catches content-model violations at conversion time rather than silently dropping ADF-only nodes like panels, mentions, and layouts.
mcpqueen/mcpqueen
The graded MCP registry: live-probes every remote server in the official registry (initialize, tools/list, schema quality, latency, provenance) and publishes evidence-backed grades — searchable by agents via its own MCP endpoint at [mcpqueen.com](https://mcpqueen.com).

chrassy/klanex-mcp
Reliable async execution for agent tool calls: schema-gate hallucinated payloads before they run, absorb rate limits and outages with retries/backoff/circuit breakers, idempotency keys, human approval gates, encrypted credentials, replay, and signed-webhook results.
