"A calculator for multiplying two numbers" matching MCP servers:

Create, read and edit native Apple Numbers documents on macOS through 38 local MCP tools, using only the native scripting API. Preserves .numbers files and formatting, with formulas, custom templates, guided chart updates, CSV imports and PDF previews; MIT licensed, with no Excel conversion or Accessibility automation.

Current, source-cited US federal tax constants and freelancer calculators for tax year 2026, including the July 1 mid-year mileage change. Every response carries its IRS/SSA primary source and a last-verified date; refuses rather than guesses.

Enables AI apps to compute GPAs from courses and credits, convert between letter and percentage grades, determine the score needed on a final exam, analyze weighted course grades, and plan the GPA required for a target cumulative result.

Model Context Protocol (MCP) server for deepwater subsea pipeline engineering: API RP 1111 external collapse limit states, hydrostatic pressure gradients up to 3,500m, Towler-Mokhatab gas hydrate phase equilibria, and Hammerschmidt MEG thermodynamic inhibitor dosage calculations.

Enables AI agents to coordinate atomic distributed transactions across a swarm through a prepare/vote phase, unanimous commit-or-abort consensus, quorum validation, and failure recovery. It also layers in vector-clock causal stamping, LWW CRDT reconciliation, and gossip dissemination so multi-node state converges deterministically without external dependencies.

Mortgage Calculator AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Calculates ROI, break-even, and cost projections for AI agents and automation projects, providing instant answers without external APIs.

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Provides agents with real Linux VMs to run commands, manage files, expose ports, and track costs, all through an ephemeral sandbox service.

Use Codex as a subagent inside Claude Code: async dispatch into a long-lived codex app-server, results pushed back into the Claude session automatically, steer/interrupt mid-task, and Codex's built-in code review.

Odds are, most of what you want to build is already open source. Tell your AI agent what you're making, and it finds it: which repos to use as they are, which to adapt, and what's left for you to write. Every repo it names is real, licensed for your use or flagged, and checked live.

Gives LLM agents spatial awareness inside Autodesk Maya, enabling scene inspection and measurement, aesthetic and engineering audits, camera planning, checkpoint/rollback safety, asset import, and viewport or render previews. Agents can also execute arbitrary Python in Maya to build and verify 3D scenes against engineering rules instead of writing blind.

Enables AI agents to subscribe to a deterministic daily ethics feed drawn from a four-module curriculum and retrieve read-only tools, resources, and reflection prompts covering principles, case studies, and codes of conduct.

Enables MCP clients to discover OpenRouter image and video models, generate and edit images, create variations, launch and monitor video jobs, and save resulting media into authorized local project directories with cost controls.

Calculate income tax (UK/US brackets), EU VAT, UK corporation tax, and capital gains tax. Provides estimates only - not professional tax advice.

Give your AI agent the entire China A-share market: 55 datasets of prices, financials, capital flows, corporate events and futures/options, stored locally and queryable with read-only SQL. Built point-in-time with delisted stocks kept, so backtests don't lie — no account, no API key.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Codebase Q&A agent with git-history awareness. Explore a repo with list_files, read_file, and search, plus git log, blame, and diff and a repo map to answer "why did this change?" questions. Runs locally as an MCP server for Claude Code and other MCP clients.

WordPress plugin that runs an MCP server on your own site: search and read published posts and pages, look up WooCommerce products, describe the site as schema.org types and query site figures, with drafts only when the site enables them. Signed-in access by default; anonymous access and OAuth are optional and off.
