How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security97
Transport & Reachability100
Schema Quality & AI Usability83
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 2101 tokens (~63/item across 33 items; 30 tools + 3 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
  • Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 65% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 30 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 32 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
  • Supports UI / widget rendering.Pass
Install

How do I install the Decision Log MCP server?

Decision Log is a hosted endpoint at https://www.decisionlog.ai/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 30 exposed · ~1,994 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the Decision Log MCP server?

Decision Log is an MCP server listed in the public MCP registry as ai.decisionlog/mcp. Append-only decisions with provenance, supersession, retrieval, and audited MCP actions. This page covers its hosted endpoint (https://www.decisionlog.ai/api/mcp).

Is the Decision Log MCP server safe to use?

Decision Log scores 94 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Decision Log MCP server expose?

Decision Log exposes 30 tools: decision_log_create_decision, decision_log_search_decisions, decision_log_get_decision, decision_log_supersede_decision, decision_log_lock_decision, and 25 more. Their descriptions and schemas cost roughly 1,994 tokens of context every time the server is loaded.

Does the Decision Log MCP server require authentication?

Yes. Decision Log asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the Decision Log MCP server still maintained?

Decision Log is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
