Decision Log does not always answer
Over the last week it answered 0.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
decision
decision_log_approve_decision_action
Record one immutable approval or rejection attestation.
decision_log_convert_candidate_to_supersession
Approve a pending DecisionCandidate as the immutable replacement for one current Decision, preserving provenance and supersession history.
decision_log_create_candidate
Create a reviewable DecisionCandidate.
decision_log_create_decision
Create an immutable Decision when permitted, otherwise create a reviewable DecisionCandidate.
decision_log_get_candidate
Get the complete visible review context for one DecisionCandidate before approving, rejecting, or converting it.
decision_log_get_current_decision
Get the newest active decision in a domain.
decision_log_get_decision
Retrieve one decision by ID.
decision_log_get_decision_governance

decision_log_get_decision_sources
Retrieve retention-safe provenance links for one visible Decision, including relationship, source lifecycle, and submitter metadata.
decision_log_get_source
Retrieve one visible SourceContent detail projection. Redacted, purged, and unknown retention states never return stored title, content, blob URL, or metadata.

Retrieve visible DecisionSource links for one SourceContent record with each linked Decision's lifecycle, authoritative current-state, and supersession identity.
decision_log_get_supersession_history
Retrieve the complete visible Decision supersession chain in oldest-to-newest order. Malformed chains fail closed and never claim a current Decision.
decision_log_list_audit_events
List the visible append-only audit events for the current Organization using the canonical permission-aware, attribution-safe projection.
decision_log_list_candidates
List reviewable DecisionCandidates visible in the current Organization and Workspace before taking a resolution action.
decision_log_list_decisions_by_domain
List decisions related to an exact domain slug.

List decisions related to an exact tag slug.
decision_log_list_recent_decisions
List the most recent decisions in the authenticated workspace.
decision_log_list_sources
List visible SourceContent using bounded excerpts and canonical retention redaction.
decision_log_lock_decision
Irreversibly prevent a current Decision from ever being superseded; may create an approval request.

decision_log_render_candidate_review
Use this when the user wants to inspect and disposition one known DecisionCandidate in a visual review workbench.
decision_log_render_decision
Use this when the user wants to inspect one known Decision in a visual card. Call a data retrieval tool first when the Decision ID is unknown.
decision_log_render_decision_explorer
Use this when the user wants to browse the five most recent Decisions and optionally inspect one in detail.
decision_log_render_source_pipeline
Use this when the user wants to inspect one known source, its provenance lifecycle, and extracted candidates.
decision_log_render_supersession_composer
Use this when the user has a known active Decision and complete replacement meaning to review before supersession.
decision_log_render_workspace_brief
Use this when the user wants a visual briefing of recent decisions, pending candidates, and source activity.
decision_log_resolve_candidate
Approve or reject a pending DecisionCandidate.
decision_log_search_decisions
Search decisions in the authenticated workspace.
decision_log_submit_source
Submit source content for ingestion and later provenance links.
decision_log_supersede_decision
Create a replacement Decision and supersession relationship for an existing Decision.

Decision Log — questions
Answers built from our own checks of this server.
What can Decision Log do?
It exposes 30 tools, read directly from the server on our last check. Among them: decision_log_approve_decision_action, decision_log_convert_candidate_to_supersession, decision_log_create_candidate, decision_log_create_decision, decision_log_get_candidate, decision_log_get_current_decision and 24 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Decision Log working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 181 ms. The bar chart above shows every period we have measured.
Did Decision Log ever remove tools?
Yes. decision_log.approve_decision_action, decision_log.convert_candidate_to_supersession, decision_log.create_candidate, decision_log.create_decision and 26 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
The registry lists Decision Log as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Decision Log?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Decision Log need an API key?
No. Decision Log completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 30 of them are readable on this page. This is what we observed, not what the docs claim.
