Pdfmakerapi

Overreach catches AI-agent scope creep. You give it the prompt you gave your coding agent and the diff it produced; it flags every part of the diff the prompt didn't authorize — unauthorized dependencies, env vars, endpoints, cron jobs, files, and features. Every finding is deterministic set arithmetic (actual − authorized), not a probabilistic opinion. Ships a GitHub Action that fails PRs on scope_creep_score=HIGH. MIT, free to use.

OpenFate Bazi MCP is a local Model Context Protocol server for deterministic Chinese Bazi / Four Pillars calculation. It supports True Solar Time correction, solar and lunar calendar input, Day Master, Da Yun luck cycles, branch interactions, reverse Bazi lookup, and transparent calculation metadata. Built on the open-source @openfate/bazi-engine and designed for Claude, Cursor, Codex, and other MCP-compatible agents.

Ambix is your product team's shared strategic memory, served as a remote MCP server. It connects Claude (and any MCP client) to your Ambix workspace — strategy, initiatives, objectives, opportunities, journey stages, insights and decisions — as structured data your AI tools can reason over, so nothing is lost between sessions or when someone leaves. Work happens in your AI tools; the context lives in Ambix. Hosted at https://mcp.ambix.ai (Streamable HTTP, served at the root, OAuth via Auth0). Listed on the official MCP Registry as ai.ambix/ambix. Learn more at https://ambix.ai.

Command firewall for AI agents. Validates every shell command before execution — binary check locally, syntax and targets via API. Sub-100ms. $0.0068 AUD per check, 80 free on sign-up.

Web content fetching and conversion for efficient LLM usage

Self-hosted, open-source MCP gateway: turn any API, database or MCP server into custom connectors for Claude, ChatGPT, Gemini, Copilot & Cursor — no code. Converts REST, SOAP, WSDL, GraphQL & SQL to MCP, with OAuth2, RBAC & audit log. 175+ pre-built adapters (Deutsche Bahn, weclapp, Etsy, DHL, Shopware).

Seekstone is a filesystem-direct Obsidian MCP server that gives Claude (and any MCP client) direct read/write access to your Obsidian vault — straight from the filesystem. No running Obsidian instance, no REST API plugin, no proxy. Most Obsidian MCP servers proxy through the Local REST API plugin, which returns full note content on every search hit — one query on a 2,000-note vault returned 1.75 MB (~450,000 tokens). Seekstone returns ranked ~200-char excerpts instead: 575× smaller payloads, far less context tax, and it works even when Obsidian is closed. 16 tools cover full-text search, scoped reads (by heading/block/line range), writes, link navigation (backlinks/outlinks), tags, and structural edits. Install: npx -y seekstone Open source (MIT) · https://seekstone.dev

Persistent memory API for AI agents. Store, semantically retrieve, and forget memories across sessions. Agents self-register via POST /signup — no human needed. Supports MCP natively, auth.md discovery, semantic search with vector embeddings, TTL, namespaces, and batch operations. Free during beta. Built for the agentic web.

Aidress is the coordination layer for autonomous AI agents. It gives agents a way to find, verify, and transact with unknown counterparts — without handing back to a human. Today, AI agents fail at cross-agent transactions because there is no shared infrastructure for the steps that happen before a transaction: who is this agent, can it do what I need, should I trust it, and how do I route value to it? Aidress provides those five layers.

Is this flight price actually good? Deal oracle for AI agents — remote MCP + REST, backed by real price history on nomad corridors.

Stop hallucinating numbers. An MCP server that runs every math expression through four independent numeric engines in parallel and returns all four results side by side — so when they disagree, you know the answer is numerically unreliable.

A Model Context Protocol Server connector for Perplexity API, to enable web search without leaving the MCP ecosystem.

Shinobi gives every AI coding agent on your machine — and every cloud Claude session — one shared task spine, decision log, and searched dead-ends ledger. Every failed approach is logged and semantically checked before an agent proposes a similar one, so agents stop repeating mistakes across sessions. Adds mobile approvals (request_approval pushes to your phone) and an autonomous dispatch/swarm that drains the backlog with N parallel agents in isolated git worktrees, all sharing one brain. Local-first SQLite over stdio, or remote streamable-HTTP MCP you can self-host for $0/mo. 39 tools, plugin system, MIT. Works with Claude Code, Claude Desktop, Cursor, Cline, Continue.dev, Zed.

Real-time infrastructure and city data for German cities via one keyless remote MCP endpoint: air quality, weather, public-transport departures with live delays, roadworks/traffic, points of interest and more (38 tools). Sources include DWD, UBA, OpenAQ, Autobahn, GTFS/HVV/VGN, OpenStreetMap and Wikidata.

Schedule and publish social media posts to 11+ platforms (X, Instagram, Facebook, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky, Telegram, Google Business Profile) from Claude, ChatGPT, or Cursor. Connect via the hosted OAuth URL (no key, nothing to self-host) or run it locally with npx and your PostFast API key.

Self-learning memory for AI tools. Remembers user preferences and context across Claude, Cursor, and Codex — with multi-parameter forgetting and cross-tool identity.

Real browser automation for AI agents. Uindow ships a local MCP server that drives a real, signed Chromium/Electron browser with genuine OS-level input (real cursor movement, real keystrokes, native file dialogs) entirely on the user's own machine. Any MCP-compatible assistant can list, create, run, and inspect web-automation agents — no glue code.

Outcome-aligned AI workflow registry. Design and run AI workflows with verifiers that align an agent to measurable outcomes, with reliable image output.

Stop hallucinating numbers. An MCP server that runs every math expression through four independent numeric engines in parallel and returns all four results side by side — so when they disagree, you know the answer is numerically unreliable.
