thequant-space
Registry code: 9e92d8e91120b637
thequant.space scores quantitative-finance research papers (arXiv q-fin and SSRN) on two 0-10 axes: math_complexity (theoretical overhead) and empirical_rigor (data quality, costs, out-of-sample validation). Quadrants: Holy Grail (high math, high rigor), Street Traders (low math, high rigor), Lab Rats (high math, low rigor), Philosophers (low math, low rigor). hub_score = 0.6*rigor + 0.4*math is the default ranking. Empirical rigor >= 7 is the credibility bar used across the site. Scores are LLM-assisted rubric judgements, not peer review. Use list_topics / list_methods to learn the filter…

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.
corpus_stats open 8h ago
Totals: papers, with code, average scores, counts by quadrant, by year (with average rigor) and by paper type, and the last update date.
{ "type": "object", "properties": {} }arguments 4 lineslist_methods open 8h ago
The 14 method hubs (econometrics-time-series, stochastic-calculus, deep-learning, reinforcement-learning, ...) with description, counts, rigor share and the slugs of the guides that teach each method's evaluation pitfalls.
{ "type": "object", "properties": {} }arguments 4 lineslist_topics open 8h ago
The 17 topic hubs with slug, description, paper count, share of papers with rigor >= 7, and URLs. Use the slug as the topic filter in search_papers.
{ "type": "object", "properties": {} }arguments 4 linesget_guide unknown never probed
Full Markdown text of one guide or learning path by slug (from list_guides), e.g. deflated-sharpe-ratio, evaluate-ml-trading-paper, score-guide.
{ "type": "object", "required": [ "slug" ], "properties": { "slug": { "type": "string" } } }arguments 11 linessemantic_search unknown never probed
Meaning-based (vector + keyword hybrid) search over the full text of every paper page, practitioner guide, learning path, calculator and post, via Cloudflare AI Search. Use it for natural-language questions ("does momentum survive transaction costs in crypto?") or when search_papers' exact keyword matching finds nothing. Returns pages with a relevance score, a snippet of the best-matching chunk and, for papers, the scores and labels. No filters beyond kind; for structured filtering use search_papers. Metered upstream: at most 25 results per call, and a daily budget; when it is exhausted the tool says so and search_papers keeps working.
{ "type": "object", "required": [ "q" ], "properties": { "q": { "type": "string", "maxLength": 300, "description": "Natural-language query." }, "kind": { "enum": [ "paper", "guide", "path", "tool", "post", "page" ], "type": "string", "description": "Restrict to one page kind." }, "limit": { "type": "integer", "default": 10, "maximum": 25, "minimum": 1 }, "rewrite": { "type": "boolean", "default": false, "description": "Let the service rewrite the query for retrieval first (one extra model call)." }, "min_score": { "type": "number", "maximum": 1, "minimum": 0, "description": "Drop matches below this relevance score." } } }arguments 42 linesask_papers unknown never probed
Aggregate questions about the corpus (how many papers disclose a Sharpe ratio / report a backtest / have code, the highest or lowest reported Sharpe, annual return or drawdown, averages, top-N, optionally in an asset class, since a year, net of costs) are answered exactly from the database with the papers linked (engine: sql). Otherwise a retrieval-augmented answer: the question is searched semantically over every paper page, guide and tool, and a language model answers ONLY from the retrieved pages, citing them as markdown links. Returns the answer text plus a sources array of {title, url, kind}. Scores quoted in the answer come from the page text; verify with get_paper. Metered (retrieval + generation): 5 calls per minute and a daily budget; when exhausted, use semantic_search / search_papers.

Search and filter the 5,000+ scored quant-finance papers. Returns compact records (scores, quadrant, topics, methods, authors, summary, paper_url, page_url) plus the total match count. Combine filters; use min_rigor 7 for credible empirical work; set has_code true for reproducible papers. Reported performance (sharpe, annual_return_pct, max_drawdown_pct, sample_start/end, transaction_costs, out_of_sample) is included when the paper discloses a backtest: filter with has_sharpe / min_sharpe and sort by sharpe or annual_return to answer 'how many papers disclose a Sharpe' or 'highest reported return' questions (use total for counts). Execution-realism flags (tcost_modeled, oos_method, data_resolution, evaluation_type) say whether trading results are net of costs and validated out of sample; empirical_rigor is capped at 6.0 when they are not (empirical_rigor_raw keeps the uncapped score). Follow up with get_paper for the abstract, score rationale and flowchart.

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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
