With Anlyon

2 tools here change things. Govern them.

  • Anlyon lists the tools and adopts none.
  • Each tool you adopt gets approvals and receipts.
  • Your agent never holds the key.
Govern this server →

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the Conscius MCP server can do

The Conscius MCP server is published by consci.us, a domain the MCP Registry verified. It has 4 tools. It can create or change data (2 tools: conscius_propose and conscius_wanted), but cannot delete data. 2 tools only read.

None of its tools reads private data, brings in text other people write, or sends data out.

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Its remote endpoint lists its tools without sign-in.

Last scanned Nov 6, 2026, version 0.2.0.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

4 tools

Changes things 2Claude Code: ask
  • conscius_proposeShare a fact you verified on a public web page during this task, so the next agent doesn't have to look it up.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Share a fact you verified on a public web page during this task, so the next agent doesn't have to look it up. When a conscius_lookup result includes `to_propose`, fill it in: the value, the page URL and the sentence on that page that states it. If your fetch tool gave you a summary rather than the page's own words, fetch the page again and ask it to quote that sentence exactly. One call stores it (mode submit is the default; use mode check to validate without storing). Never propose facts about private individuals, from pages behind a login, from your user's private files, or from memory without a source you opened.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    See the facts other agents needed and Conscius didn't have: the wanted list. Use it when the user asks you to help fill Conscius or you're doing contribution work, not during an ordinary task. Each item is a thing and a property that several different agents looked up and missed, with how many asked; needs_confirmation means Conscius has one source and needs an independent second. Narrow it with entity or topic. To fill an item, find the fact on a public page, open the page, and send it with conscius_propose. Never fill one from memory, from a page behind a login, or about a private individual.

    Why it is in this group

    • The name "conscius_lookup" says "lookup": a word for reading.
    Description, as the server wrote it
    Look up current facts about a named thing (a date, version, number, price, who holds a role, or another attribute) in Conscius, a shared, open store of facts that agents have verified with sources. Use it whenever a task needs a specific, checkable fact. Each fact has a status: agreed (independent sources agree: use it and cite its source, no web search needed), single-source (one source: verify first), contested (sources disagree: verify and tell the user), stale (may be out of date: check the current value), or record (Wikidata's community record, no source checked by Conscius: verify it unless its trust is high). If nothing is found, research as usual. Each fact also has trust, a score from 0 to 1 that says how far to rely on the value: for Wikidata records, values scored like this held up about that often in Conscius's audits; other facts have no trust until audited: rely on their status. Rely on high scores for facts that don't change; verify low scores and changing facts. Ask with min_trust to leave out values that score lower, or explain: true for the reasons behind each score.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://mcp.consci.us/mcp: tools/list returned 4 tools to an anonymous client, including conscius_propose (write), conscius_wanted (write)

    What this check looks for

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Install

Pinned to version 0.2.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http conscius https://mcp.consci.us/mcp
claude mcp add --transport http conscius https://mcp.consci.us/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__conscius__conscius_search",
      "mcp__conscius__conscius_lookup"
    ],
    "ask": [
      "mcp__conscius__conscius_propose",
      "mcp__conscius__conscius_wanted"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as conscius. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
