A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• get_composite

  Everything the platform knows about one ticker in a single record: the cross-signal consensus, each contributing dimension with its direction and provenance, and risk flags. Start here for any question about a specific company.

• get_demo_composite

  A single fixed demo ticker, callable without an API key, so the data shape can be inspected before signing up. Returns only the demo ticker regardless of input. For real tickers use get_composite, which requires a free key.

• get_evidence

  Paid key required. The primary documents a ticker's signals were derived from — insider Form 4s, institutional holdings and macro series, with the filing each came from where one is available. Use this to cite a claim rather than assert…

• get_house_rating

  Paid key required. The platform's own buy/hold/sell rating for a ticker, with the reasoning behind it. A judgement about the stock, not a recommendation to any reader. Paid keys are not on sale yet.

• get_consensus

  Whether the independent actors this platform tracks — insiders, Congress, institutions, the model — agree on one ticker, with the per-dimension breakdown that produced the verdict.

• rank_consensus

  The names where independent actors agree most strongly, ranked. Use this to find candidates rather than to check one you already have in mind.

• screen

  Filter the whole equity universe and return matching tickers with their scores. The bulk discovery tool: use it for questions of the form 'which companies have X'. To rank by cross-signal agreement instead, use rank_consensus.

• get_monthly_activity

  Rank ticker activity aggregated from available published filings by transaction date for the current UTC month through today. Includes coverage metadata and unknown-value counts; this is not total market activity. Congress: 10 names on…

• get_historic_moves

  The historical distribution of 5-day and 1-month returns for a ticker, sampled over the last 5 years: mean, standard deviation, percentiles, a histogram, and the worst drawdowns with their dates. Use it to say whether a move is unusual…

• list_equity_perp

  Funding rate and open interest for the ~51 US single names listed on a 24/7 perpetual futures venue, ranked by notional. This is the ONLY source here that moves outside US market hours, so it is what to check overnight and at weekends…

• get_equity_perp

  Funding and open interest for a single name on the 24/7 perpetual venue. Most tickers are NOT listed there — only about 51 of about 4,600 covered tickers — and a 'not listed' answer means no venue coverage, never that positioning is flat…

• search_tickers

  Resolve a company name or partial symbol to tickers the platform covers. Use this first when the user names a company rather than a symbol.

• get_signal

  A whole-market gauge rather than a per-company one. 'macro' is the market-regime read, 'energy' the macro energy balance, 'crypto' crypto positioning and funding, 'rate_expectations' the market-implied path for policy rates. Use these for…
