api record

For a why or how question ("why did X become dominant", "what led to Y"), call ask first: it returns an editor-written chain of dated, sourced entries when one exists, and otherwise the questions that do exist. A chain's steps are ordered by argument, not by date: each step carries its date and a group (the strand of the argument), strands come in argument order and steps inside a strand run forward in time, so present them in that order and do not re-sort them by date. search_entries matches keywords, so use concrete nouns (product names, company names, a law, a number) rather than abstract…

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.

  • list_timelines open 4h ago

    Every timeline on the site with its topic, tags, entry count, date range, last update and a short summary. Start here to find the slug for get_timeline.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • search_entries open 4h ago

    Find dated entries across every timeline by keywords, party id, timeline slug and date range. Every keyword must match (title, summary, party or timeline name); results are ranked, newest first among equals. Returns the entry text and url; call get_entry for quotes and sources.

    mcp-tool

  • get_party unknown never probed

    Everything the site records about one company, person or regulator across every timeline: its role on each, the parties it most often appears alongside, and every dated entry that names it, newest first, with sources. Use it instead of search_entries when you want one actor's whole history rather than a keyword match. Returns at most limit entries, with total_entries saying how many exist; a party is named when the editors listed it among an entry's parties, not merely when the name appears in the text.

  • get_timeline unknown never probed

    One timeline in full: TL;DR, dated entries newest first with sources and quotes, relations between entries, links to other timelines, what to watch next and open questions. Pass since=YYYY-MM-DD to get only entries dated on or after that day (what changed recently).

    mcp-tool

    arguments 26 lines
  • get_entry unknown never probed

    One dated entry in full: its summary, type, the parties it names, every source with the outlet, the publication date and the verbatim quote it was read from, plus the relations and cross-timeline links it takes part in. Use it after search_entries or get_timeline has found an entry and you need the exact wording and source URL to cite. Entry ids are unique within a timeline, not across the site, so pass the slug the entry came from.

    arguments 20 lines
  • upcoming unknown never probed

    Scheduled dates the timelines are watching — earnings, rulings, launches, rule deadlines — each with why it matters, the timeline it belongs to and a source where one exists. Use it to answer what happens next across the site, rather than reading each timeline for its own catalysts. Returns the dates from today to the horizon, oldest first, echoing back today and horizon; a date known only to the month carries precision=month and is matched on the month.

    arguments 18 lines
  • ask unknown never probed

    Answer a why/how question as a chain: an ordered set of dated, sourced entries from the timelines with one line on why each led to the next, written by the editor rather than generated. Returns the best-matching chain with every step's entry (URL, date, summary, sources), or, when no chain fits, the questions that do exist and how to research the answer with the other tools.

      "type": "string",

      "minLength": 3,

_ 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
100%

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.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
