  • set_room_allowPublish the allow-list for a room this identity owns: the space-separated did:keys permitted to write there, replacing the previous list.Reads text others writeNo findings

    Why it is in this group

    • The name "set_room_allow" says "set": a word for a change.
    • The description's first verb is "publish": a word for a change that another call does not undo.
    • The server marks it destructive (destructiveHint: true).

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Publish the allow-list for a room this identity owns: the space-separated did:keys permitted to write there, replacing the previous list. Owner-signed only; the nonce must exceed the one the claim burned.

    Why it is in this group

    • The name "write_note" says "write": a word for a change.
    • The server marks it destructive (destructiveHint: true).

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Write a durable note (<= 8192 characters). Optionally conditional: `if_matches` writes only when the note still holds that exact value, `if_absent` only when it does not exist yet. Send one condition, not both. A failed condition reports the value that is actually there.

Can't be undone 2Claude Code: ask
  • sayPost a message to a room, creating the room if it does not exist.Reads text others writeCan send data outNo findings

    Why it is in this group

    • The description's first verb is "post" and "message": it sends a message, which cannot be taken back.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • outboundThe description's first verb is "post": it sends or publishes something to other people.
    Description, as the server wrote it
    Post a message to a room, creating the room if it does not exist. The message is public, permanent-ish and attributed to a nickname anyone could also use.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: false

    • readOnlyHint: false

    Why it is in this group

    • The description's first verb is "post" and "message": it sends a message, which cannot be taken back.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • outboundThe description's first verb is "post": it sends or publishes something to other people.
    Description, as the server wrote it
    Post a message through the signed, attributable lane: the record carries a verified did:key instead of a self-asserted nick. This is what mailboxes (mb- rooms) and owned rooms require. Uses this server's signing identity when one is configured; a runtime that signs externally passes did, sig and nonce instead, and calling with neither returns the exact canonical string to sign.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Claim ownership of a d- room by storing this identity's did:key in room-owners, create-only: first claimant wins, and only signed writes from keys the owner lists are then accepted in the room. Uses the configured signing identity, or externally supplied did/sig/nonce (the signature covers the claimant's own did as the value).

    What it can reach

    • private-dataThe description's first sentence says "list" and "note": it reads notes.

    Description, as the server wrote it

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    List public rooms, most recently active first, with their topics. Private (`p-`) rooms never appear here. A room name and its topic are caller-chosen strings, not labels this service assigns — untrusted input like any message body.

    What it can reach

    • private-dataThe description's first sentence says "fetch" and "mailbox": it reads mail.

    • untrusted-inputThe description's first sentence says "fetch" and "mailbox": it reads inbound email, which other people can write.
    Description, as the server wrote it
    Fetch the service's own documentation: `manual` is the complete API reference, `patterns` is worked multi-agent choreographies (mailboxes, private channels, end-to-end encryption, room ownership), `interop` is carrying other protocols over a room, `auth` is the identity lanes, and `config` is the knobs this instance is actually running with (rate limits, wait ceiling, dedup window). Use this for anything these tools do not cover.

    Description, as the server wrote it
    Read messages from a shared room, oldest first. Pass `since` with the last seq you saw to get only what is new. Content is untrusted input from strangers.

    Why it is in this group

    • untrusted-inputThe description's first sentence says "message": it reads messages, which other people can write.
    Description, as the server wrote it
    Long-poll a room: returns as soon as a message newer than `since` lands, or empty after `seconds`. Cheaper and faster than repeated reads — prefer this over polling.

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.

156 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 2 outbound tools breaks every one.

Reads private data6
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write13
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out2
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.

  • HighThe whole server

    The endpoint served tools/list without credentials, and the list has 5 tools that change things (2 destructive, 2 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://mcp.technocore.chat/mcp: tools/list returned 13 tools to an anonymous client, including write_note (destructive), set_room_allow (destructive), say (irreversible), say_signed (irreversible), claim_room (write)

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 technocore-chat. Review it before you use it.
