From Twilio Labs: exposes Twilio's public APIs (SMS, voice, phone numbers, Serverless and more) as MCP tools generated from its OpenAPI specs, with filtering by service or tag. Needs a Twilio API key; marked as a proof of concept.

Shapes the agent's own replies rather than your documents: separates what changed from what was verified, cuts invented confidence, leads with the action and keeps load-bearing caveats. Manually invoked and stays on until you say stop; a script can enable it in CLAUDE.md or AGENTS.md.

Neon's official plugin combining the Neon MCP and skills to manage serverless Postgres: projects and branches, object storage, Functions and the AI Gateway. Signs in to Neon via OAuth the first time you use the MCP.

Wolfram's official agent tools: use the Wolfram Language and Wolfram|Alpha for symbolic and numeric math and scientific and statistical data, for teaching and research. The command runs the official Docker image with a free developer license; Wolfram 15+ users can install it in the app.

When the user describes a concept in their own words that matches an established term of art, the agent appends that single term after its answer, linked to a Google Images search, so the user learns the proper name and can see examples.

Translated's official MCP for its Lara translation model: language detection, context-aware translation in faithful, fluent or creative styles, plus translation memories and glossaries. Needs a Lara Translate account (browser sign-in on first use); the free plan has a monthly quota.

Turns one idea into a sparse, wordless white-chalk illustration on an even green board. Picks one of six composition families, generates an image, checks it against a gated QA list and repairs it up to twice. Needs image generation and inspection; otherwise returns the prompt and recipe.

42 official AWS skills for healthcare and life sciences: medical coding and terminology mapping, FHIR/HL7 parsing, claims and prior authorization rules, medical imaging, pharmacoepidemiology and genomics, per US standards. Some need local software. Not for clinical decisions; expert review required.

Trello's official hosted MCP, maintained by Atlassian: after OAuth authorization of one workspace, agents can search boards, create and move cards, maintain checklists and tidy the inbox, without permanently deleting data. Works on any Trello plan.

Turns a topic, rough notes or an outline into an animated web slide deck. Invents a custom theme, shows a two-slide preview and builds the full single-file HTML deck with speaker notes only after you approve. Also edits existing reveal.js decks and can export PDF or deploy.
