Transform mathematical images to LaTeX, chemistry structures to SMILES, and documents to markdown with security-first design. Features HTTPS enforcement, path traversal protection, structured logging, and complete MCP (Model Context Protocol) server integration. The geodesic path to mathematical OCR in Ruby.

A Model Context Protocol server for Mathpix OCR, over stdio or Streamable HTTP (bearer-token auth). Exposes tools to convert images and PDF/DOCX/PPTX documents to LaTeX and Markdown, with descriptive errors and optional file output for large results.

Add MCP tool serving to any Rails app. Write @rbs type annotations with predicate tags (@requires, @feature, or custom) and the gem compiles per-user JSON Schema automatically — filtering fields by permissions, feature flags, and plan tiers at request time.

Snapshots an MCP server's public surface (tools, resources, prompts, capabilities) into a committed mcp.lock.json and fails CI when the contract changes in a breaking way.

Exposes tools over HTTP (SSE) using the MCP SDK.

Mountable Rails engine that records every Model Context Protocol request a Rails app serves and renders its tool contract as documentation.

A Ruby implementation of a Model Context Protocol (MCP) server using stdio transport.

mcp_toolkit extracts the shared MCP-server framework that Smily's apps grew independently: a Streamable-HTTP transport, cache-backed sessions, central-app token introspection (satellite + authority roles), a registry-driven "generic tools over N resources" dispatcher, and an injectable serializer DSL. It wraps the official `mcp` gem as the JSON-RPC core so each app ships only its serializers, resource registrations, and scope blocks.

Load any Thor CLI directly as a StdIO MCP server

MCP servers focused on fetching and presenting information from Obsidian vaults

A unified DSL for exposing structured data and operations across analytics tools (PowerBI), no-code platforms (PowerAutomate), and AI agents (via MCP).

Model Context Protocol server for Panda CMS. Provides tools for managing pages, posts, and collections via Claude Desktop and other MCP clients.

CLI toolkit providing memory, hooks, and MCP servers for Claude Code personality system

Phronomy is a Ruby AI agent framework that provides composable building blocks — Agents, Workflows, Tools, Filters, and Tracing — for building AI agents in Ruby. Powered by RubyLLM for LLM abstraction.

pikuri-mcp adds Model Context Protocol support to pikuri-core agents: a +Pikuri::Mcp::Registry+ for declaring stdio + HTTP MCP servers, the +Pikuri::Mcp::Servers+ runtime that spawns them, a +Pikuri::Mcp::Synthesizer+ that LLM-fills missing server descriptions, a +Pikuri::Mcp::Verifier+ that screens server surfaces for prompt-injection patterns before any tool is advertised to the LLM, and a +Pikuri::Mcp::Extension+ that wires everything into a +Pikuri::Agent+ via +c.add_extension(...)+ in the +Agent.new+ block.

Pinmark adds a dev-only floating overlay to any Rails app. Click a component or any element on the page, leave a comment, and Claude Code consumes the queue via MCP — closing the loop between visual feedback and source edits. Works with Phlex, ViewComponent, and ERB partials.

Protocol-only core gem: Adapter contract, capability registry, manifest builder, and an MCP server wrapper. No commerce-backend deps.

Every other portage-ucp gem lets a Ruby program expose a commerce backend to agents (server side). This gem is the other direction: connect to somebody else's /.well-known/ucp manifest, or drive your own Adapter directly, and place an order as the client. Three transports behind one interface (loopback over an in-process Adapter, stdio, Streamable HTTP) — callers never know which they got. Depends only on portage-ucp + the mcp gem's client half; no adapter gem is a dependency.

Rails-AI-Bridge introspects your Rails application and exposes structure to AI assistants via static context files and a live Model Context Protocol (MCP) server. It classifies Active Record models semantically (Core, Join, Supporting), optionally surfaces non-ActiveRecord Ruby classes under app/models (tagged POJO/Service), and integrates with editors and assistants such as Claude, Gemini, Cursor, and Windsurf.

Rails Hyperdrive mounts an MCP (Model Context Protocol) server at /_hyperdrive/mcp in development, exposing introspection tools for AI coding agents (eval Ruby, query DB, tail logs, list models/routes, locate source, fetch docs, snapshot stack). It also ships a `hyperdrive:init` generator that discovers and installs two artifact types — lazy skills and eager guidelines — shipped by companion gems under a documented contract. rails-hyperdrive is the mechanism; companion gems (rails-hyperdrive-<library>) are the content.
