The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search_conversations auth-required 54m ago

    Searches for Google Chat conversations (named spaces, direct messages (DMs), or group chats) by display name or participants to find conversation IDs. This tool searches conversation metadata, NOT message contents. To search within message history or find messages by keyword/sender/timestamp, use `search_messages`. If only `participants` are provided, this tool finds 1:1 direct messages (if one participant is provided) or group chats (if multiple participants are provided) that include the specified participants and the calling user. If only a `query` is provided, this tool searches for conversations where the query is a case-insensitive substring of the conversation's display name. If both `participants` and `query` are provided, this tool finds conversations by participants and then filters them by display name. If neither `participants` nor `query` are provided, this tool lists all conversations the calling user is a member of. This tool only lists conversations the calling user is a member of. Returns a list of conversation objects containing conversation IDs (format: `spaces/{space}`), display names, and conversation types. IMPORTANT: An empty `conversations` list does not mean there are no more results overall. If `next_page_token` is present, more pages can be fetched. If you get an empty list but a `next_page_token`, ask the user if you should continue the searching.

  • search_messages unknown never probed

    Searches for Google Chat messages using keywords and filters returning them in Markdown format. Works across all spaces the user has access to, or can be scoped to a specific conversation. Follow this guidance when deciding to use `search_messages` vs other search or read tools: - Use `search_messages` when looking for specific message content, keywords, mentions, links, senders or unread messages potentially across multiple spaces or without a known conversation ID. - Use `list_messages` when you know the specific space or thread ID and want to read messages sequentially in chronological order. - Use `search_conversations` to find space metadata such as conversation IDs by space display name or participants (it searches metadata only, not message contents). If `searchParameters` is provided without specific filters, recent messages across conversations accessible to the user are returned.

    Retrieves messages from a specified Google Chat conversation (Space, direct message (DM) or group DM) in Markdown format. Allows filtering by thread, time range, and number of messages. Additionally, the next page of messages can be retrieved to allow for more context. Private messages (messages only visible to a single user) are filtered out.

  • send_message unknown never probed

    Sends a Google Chat message to a conversation with Markdown formatting. This tool uses a conversation ID, an optional thread ID, and a message text as inputs. Conversation IDs can be found using the `search_conversations` tool. It returns the created message.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
