"Shell" matching MCP servers:

Enables AI hosts to perform reproducible psychometric and statistical analyses through constrained, schema-validated tools such as item analysis, Rasch modeling, descriptive statistics, and correlation matrices, without exposing arbitrary R or shell execution.

Enables AI assistants to search, read, and compare publicly ranked applications, chatbots, and labeled news records with dated citations, and to submit new applications or check private submission status using email OTP bearer tokens.

Connects a Zotero research library to AI assistants so users can search items by title, author, tag, collection, full text, or meaning, read metadata and PDF content, add annotations, and add or organize papers by DOI, URL, ISBN, or BibTeX. It works in local or web mode and is available both as an MCP server for chat apps and as a CLI plus agent skill for shell-based agents.

Wraps SHELX crystallography programs for structure solution and refinement via a chat interface.

Stdio MCP server over the Briefing Service REST API: hourly LLM-ranked news briefings (AI, frontier labs, markets, sports, world) as structured JSON, rendered e-ink pages and a free provenance dump. Six read-only HTTPS tools, no shell, no secrets required; Dockerfile and glama.json in the repo root.

Exposes each stage of the Champollion sulcal embedding pipeline as MCP tools, enabling agents to run, monitor, and debug the pipeline without manual shell commands.

Query 20 structured datasets from AI agents — healthcare providers (9M NPI records), SEC EDGAR filings, PACER federal courts, USPTO patents and trademarks, OFAC sanctions screening, crypto whale wallets, DeFi liquidation signals, Polymarket smart money, economic indicators (FRED/BLS), federal contracts, NOAA weather, and OTC shell risk scoring. Pay per query, no subscriptions

Enables an AI agent to set up, run and verify engineering simulations through typed tools — creating or importing cases, setting boundary conditions, running solvers, checking convergence, verifying results against references, and rendering output, with edits appearing live in the GUI. It exposes no shell or code-execution tool.

A local stdio MCP server that exposes tools for running evidence-first research with source-linked, replayable reports, plus replay, citation-audit, and Agent Reach health checks. It preserves fetched page text, exact quote offsets, hashes, and run traces so a client can verify that quotes match retrieved sources, while withholding arbitrary shell or local-file access.
