Exactly-once execution for agents that move money: the same payment can't settle twice across processes or retries. World-confirmation asks the provider ("did this charge actually land?") and returns CONFIRMED_ONE / MULTIPLE / ABSENT / UNKNOWN; out-of-band reconcile catches spend that bypassed the gateway; earned-autonomy licensing (L0–L5) only raises an agent's unattended spend ceiling on proven-clean history. In the official MCP Registry as `io.github.aurumflux20/seal`. `pip install seal-kernel`

Agent-native teaching OS: gives your AI a classroom that remembers. 50 tools for courses, lessons, FSRS flashcards, graded exercises, real-time teaching sessions, and teaching-memory read-back (`get_context`) — the agent authors and grades, reflects with evidence, and revises its own lessons; lesson completion belongs to the learner. Self-hosted (Postgres + web app), MIT.

The PredictLeads MCP (Model Context Protocol) server lets AI agents access PredictLeads data and services directly. It exposes a structured way to interact with the PredictLeads API and retrieve all information available through it. Every tool maps to an individual PredictLeads API endpoint with the same available parameters. One additional tool exposes the full OpenAPI schema, so an AI agent can determine which tool to use — and how — for a given prompt. PredictLeads provides company intelligence data: Companies Technology detections, Job openings, Financing events, Categorized News Events, Similar companies, GitHub repositories, product launches, company connections, and more.

Delegate multi-file implementation from Claude Code, Codex, or Copilot CLI to Cursor's CLI agent (Composer 2.5) over ACP. Returns a typed result — final message, agent-reported changed files, session id, and plan — instead of scraped terminal output. Plan mode drafts first, then resumes the same session to implement; clarifying questions come back as normal results rather than stalling. Ships plugin manifests for Claude Code, Codex, and Copilot. MIT.

Reference implementation of an "operational ontology": MCP tools are generated from a typed business domain model (objects, links, actions) — one tool per query shape and per action, deliberately no raw SQL tool. Writes pass business-rule preconditions, are audited, and write back to the systems of record; refusals are machine-readable. Demo scenario included (`pnpm demo` / `pnpm mcp`).

Curated Korean AEC knowledge — not just code lookup. Standards (KDS · KCS · KS · statutes) and domain expertise sit on one graph, so it answers **why** a figure holds, **what order** work goes in, and **how** two methods differ — each with the clause or the evidence attached. Abstains when it has no grounds. Remote endpoint `https://mcp.den.archi/mcp`, free beta at https://den.archi.

Deterministic (no-LLM) pre-execution filter for agent tool calls. Pattern-matches known scope-creep (out-of-mandate writes, credential-file reads, SSRF, destructive shell/SQL) and prompt-injection vectors and blocks them in ~25 µs. Runs as standalone guard tools or a fail-closed transparent proxy in front of any downstream MCP server. Signatures from the Aletheia research paper; a first-line pre-filter, not a sandbox. Registry `io.github.vikasny30/aletheia-mcp`. `npx -y aletheia-mcp`

Freedom-of-information requests for Germany via [FragDenStaat.de](https://fragdenstaat.de), the FOI portal built on [froide](https://github.com/okfde/froide). Finds the responsible authority from a place name and returns the evidence trail, reads the applicable act and its statutory deadline, tracks your own requests and their replies, and drafts new requests as local YAML checked against 25 rules before anything is sent. Four tools need no account. Submitting is guarded by five independent gates and defaults to a dry run, because the API sends immediately and cannot be undone.

A friendly helper for AI assistants that need to look things up on the web and manage a local research stash. Research Friend is an MCP server that gives your AI tools the ability to fetch web pages and search the internet. It uses a real web browser behind the scenes, so it works even with modern websites that rely heavily on JavaScript. It also includes a local “stash” for storing documents, extracting text, and searching across your library. To make use of all its features, you'll want an MCP client that supports prompts (common) and sampling (less common). We're building Research Friend alongside Chabeau, which supports both.
