Enables coding agents to publish HTML pages and small sites over MCP, returning a stable link and keeping every version, with access limited to specific people, an organization, or anyone with the link.

Generates a unique number derived from the International Space Station's current orbital location, useful for space-derived identifiers or deterministic random seeds.

Enables users to fetch number trivia, historical date facts, math properties, and random number facts through the NumbersAPI.

Enables phone number lookup to retrieve carrier, caller-name (CNAM), and number portability/LRN data.

Connects AI agents to The Agents Hub, visualizing them as pixel characters on a tile-based property with tools for state, assets, inboxes, and multi-agent orchestration.

Enables AI agents to search The Met's open-access collection by keyword with filters for images, on-view status, medium, and year range, and to fetch rich object details such as artist bio, dimensions, department, and gallery number. Also lists the museum's curatorial departments so searches can be scoped, all without an API key.

MCP server that wraps the StupidAPIs' 'The Committee' tool, which convenes five random number generators to argue and vote with one always dissenting.

Local MCP server (stdio) exposing the entire Hetzner Cloud API as 201 typed tools, read and write

Enables searching and retrieving articles, sections, and tags from The Guardian via the Guardian Open Platform API.

Exposes 11 agent-native QA tools over stdio so coding agents can discover a project, analyze risk, select the smallest relevant test set, generate and dry-run tests, triage failures, propose tiered heals, analyze flakes, generate quality reports, and evaluate release readiness. Planning and healing tools stay read-only or propose-only, while execution defaults to dry-run, keeping agent actions safe and evidence-backed.

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

Number utilities MCP server providing base conversion, Roman numeral conversion, and English word spelling of integers.

Provides a random number aged 24 hours, offering a smooth, aged number for any purpose.

Generates random numbers via a single tool, part of the Pipeworx MCP gateway providing access to multiple data sources.

Exposes tools to calculate powers (square, cube, etc.) of a number via stdio or HTTP/SSE, with an additional resource and prompt on the HTTP variant.

Read-only MCP server that proxies The Game Pensieve API over Streamable HTTP, letting AI assistants query a personal game collection via tools like search, filters, and summaries. Supports OAuth 2.1 enforcement and owner-scoped access.
