Lets an AI agent pull the user's own Douyin creator-backend work data — plays, likes, comments, shares, saves, 5-second completion rate and more — into a locally accumulating CSV plus a daily overview, with tools for status checks, fetching, merging, and retrospective analysis. Access is read-only to the user's own account, needs no third-party dependencies, and keeps all data on the local machine.

An MCP server for executable mathematics that enables agents to construct objects, compute invariants, search for witnesses, and verify results with independently checkable evidence.

RiskModels decomposes any US stock or portfolio into market, sector, subsector, and residual risk components with executable ETF hedge ratios — enabling portfolio managers to understand risk exposure and construct precise hedges programmatically.

MCP server for the DAG Studio causal-inference engine, enabling AI agents to construct, analyze, and validate causal directed acyclic graphs (DAGs) through tools for analysis, data simulation, and code generation.

Enables users to search the SNAC Cooperative's index of archival collections and the people, families, and organizations linked to them, and to construct ArchiveGrid search links. It helps genealogists and historians discover which repositories hold papers and related collections.

Give AI agents and LLMs access to podcast data from Rephonic — covering 3+ million podcasts with listener estimates, demographics, contact details, chart rankings, episodes, and more.

Minimalistic MCP server that lets AI assistants inspect, quality-check, and clean CSV datasets through tools, resources, and prompts, without needing local file access.

Integrates the miEAA 3.x bioinformatics platform with Claude Desktop, enabling microRNA enrichment analysis, identifier conversion between miRBase versions, and miRNA-precursor transformations through natural language.

Enables interaction with an explicit ARC-AGI-3 world model through typed operations for actor/rule editing, deterministic simulation, rendering, and observation comparison.

Enables AI assistants to perform anonymous financial analysis on uploaded general ledger (GL) exports, covering ratios, DSCR, cash flow, and other diagnostics, with deep links to the K-Phi platform for conversion.
