Troubleshoot Superset MCP health, validation, permission, response-size, and bug-report workflows. Use only for MCP tool workflows; do not use for direct API work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# preset-mcp-troubleshooting Use when Superset MCP tools fail, return validation errors, return permission errors, or produce oversized responses. ## Always - Stay on MCP troubleshooting; do not switch to direct APIs. - Use `health_check` first for service availability on a direct connection. On the Preset gateway, `health_check` is a workspace tool reached through `call_tool`; follow `preset-mcp-gateway` for gateway authentication, scope, workspace, and service failures. - Use `generate_bug_report` when the user says MCP is broken or asks how to report an issue. - Treat permission denied as authoritative. - No permission workaround: do not search alternate tools, REST APIs, or direct APIs to expose restricted data. - Use live tool schemas to fix validation errors. ## Decision Rules - Connection or availability issue: `health_check`. - Tool parameter/schema issue: inspect the live tool schema and retry only with corrected MCP arguments. - Permission issue: explain the denied operation and stop; do not search for alternate tools to expose restricted data. - Response too large: rerun with narrower filters, identifiers, page sizes, or row limits. …

How to install
mdr add preset-io/agent-skills/preset-mcp-troubleshooting@sha256:6849f91fbf7cea7bThe line at the top of this page pins the label git:20261007.d55e493, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
