heimdall-ledger

heimdall-ledger is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from randomittin/heimdall. Its token cost is not measured, scanned A, original, MIT.

An MCP server for recording and retrieving information for the Heimdall system. MCP is a standard way for an AI agent to use external tools and services.

In plain words
What is it for?
It is intended to support Heimdall through its ledger service, but the available details do not specify concrete user-facing jobs.
Why use it?
The input only identifies its server command, so its specific stored information and operations are not described.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the hmd plugin — 4 skills, 18 commands, 16 agents, 5 hooks, 1 MCP server shipped together

Security

Grade A, and why

heimdall-ledger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
