An MCP server, a program that lets an AI agent connect to outside tools, called Stacktree, hosted at api.stacktr.ee.

Use it to configure a remote Stacktree connection, or install a local command-line setup with the documented npm commands and API key option.

The supplied information only identifies its connection details and authentication options, so its specific tasks are not described here.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

stacktree 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 yesterday.

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.

  "stacktree": {
    "type": "http",
    "url": "https://api.stacktr.ee/mcp",
    "note": "Official Stacktree MCP server. OAuth 2.1 with dynamic client registration; the agent is prompted to authorize on first connection. Publishing a single 24-hour page needs no account at all. For a stdio setup instead, run `npx stacktree-install` or `npx -y stacktree-mcp` with STACKTREE_API_KEY."

Changes

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.
