"Sage" matching MCP servers:

A multi-tenant MCP server platform that hosts isolated MCP servers with OAuth/API key authentication for 23+ services, enabling integration with Claude Desktop and other clients via a web interface and CLI.

A unified MCP server for AWS that enables natural language infrastructure management, cross-service resource discovery, and dependency mapping. It features 30 intelligent tools for cost optimization, incident investigation, and multi-account operations protected by a robust safety system.

Enables querying graph invariants and properties, such as matching covered, brick, and snark characteristics, via SageMath-backed MCP tools.

A universal mathematics MCP server that gives LLM clients full access to SageMath for symbolic calculus, number theory, linear algebra, and more, with persistent state across tool calls.

MCP server for querying OpenAI usage and cost data, including spend summaries, daily breakdowns, month-over-month comparisons, and token usage by model.

Enables MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

Enables AI agents to query Japan's 47 prefectures' regional minimum wages from official MHLW statistics, including hourly rates, effective dates, and 24-year history.

I gave Claude a mass grave of 200 markdown files and now it remembers my entire project between sessions. No cloud, no API keys, one 10mb Go binary, and private. Stateless Agent Memory Engine is your synapse to the CLI.

Enables safe read and edit operations on Things 3 tasks, projects, and checklists using only documented AppleScript and URL scheme APIs, without accessing private databases.

A secure SSH MCP server that enables execution of read-only diagnostic commands over SSH, preventing modifications to remote systems.
