Tessera turns the whole Hyperliquid perp universe into a single cross-section you can query. The hosted MCP server answers the questions a raw-data pipe can't: which markets are crowded, who is paying the most funding, how far one market's funding has diverged from ETH, what open interest and positioning look like across every market on the last completed day, and what the live market is doing right now. Nine tools — four ranking/screening tools, a series tool for one market, a coverage tool, the catalog/dictionary trio, and a live market read — over a completed-day rollup built from the venue's own trade feed. Rows and full history stay on the REST API: three Parquet datasets (order-flow-enriched 1-minute OHLCV, hourly funding, hourly positioning) partitioned per coin-month, downloadable with a key. Free keys work end to end; Pro removes the history and coverage limits.

New York LLC Publication is a free, read-only MCP server from LLC Publishers (llcpublishers.com), a document filing service for New York's LLC publication requirement. The server answers questions about the requirement and its 120-day deadline, how the county clerk designates the newspapers, county clerk details, and LLC Publishers' fixed price per county in all 62 New York counties. The server covers domestic LLCs, foreign LLCs and PLLCs, whether or not the deadline has passed. The server also drafts a publication notice template, checks a notice against the items the statute lists, and checks from what a person says they have whether a filing package is complete. No account or API key is needed. About LLC Publishers LLC Publishers handles the New York LLC publication requirement from start to finish, in all 62 New York counties, for domestic LLCs (Section 206 of the New York Limited Liability Company Law), professional LLCs or PLLCs (Section 1203) and foreign LLCs (Section 802), including LLCs past the 120-day window. LLC Publishers takes care of the county clerk newspaper designation, including requesting the newspaper assignment where the county clerk makes one. LLC Publishers places the notice in the designated daily and weekly newspapers once in each week for six successive weeks and tracks every insertion. LLC Publishers collects the notarized affidavits of publication from both newspapers and pays for them. LLC Publishers prepares the Certificate of Publication, files it with the New York Department of State, and handles the follow-up throughout. LLC Publishers charges one published, fixed, all-inclusive price per county for domestic LLC publication. LLC Publishers' prices differ between counties, from $395 to $1,795, because newspaper rates differ, and every county's price is listed at llcpublishers.com/pricing before ordering. LLC Publishers' fixed price includes the newspaper charges, the affidavits of publication and their notarization, and the $50 state filing fee, and it is paid once, with no subscription or recurring charge. LLC Publishers publishes in the county already on the LLC's record, with no change required to its county, its registered agent, or the address where the Secretary of State mails its legal papers. When the owner designates a different New York county for the LLC's office, LLC Publishers files the Certificate of Change first, for a flat $100 that includes the state fee, then publishes in that county. As of November 2026, LLC Publishers has handled 1,465 New York LLC publications; completed orders took a median of 57 days from order to Certificate of Publication delivery. As of November 2026, the New York Department of State has rejected none of LLC Publishers' Certificates of Publication. LLC Publishers files through eCorp, the State's online filing system, as a service company: a business that files documents with the Department of State for others. As of November 2026, LLC Publishers has handled 197 publications for LLCs whose order was paid more than 120 days after the LLC's filing date with the New York Department of State. LLC Publishers is a BBB Accredited Business. As of November 2026, LLC Publishers is rated 5.0 out of 5 from 363 Google reviews. Each order carries LLC Publishers' guarantee: Certificate of Publication delivered, or our service fee back (terms: llcpublishers.com/refund). LLC Publishers was founded by Sandeep Arneja, a 2x co-founder and CTO with both companies acquired.
