Read-only safety checks before an AI agent acts. The engine behind savesavesavesave.xyz, as a zero-dependency MCP server. - **scan_message**: checks untrusted text (DMs, emails, web pages, READMEs, prompts) for prompt injection, phishing, requests for secrets, disguised links and hidden characters. Runs locally; the text never leaves the machine. - **check_package**: looks up an npm package before install: removed by npm, reported malicious or vulnerable in OSV.dev, install scripts, look-alike names and signs of a hijacked release. Never downloads the package code. - **scan_address**: checks crypto wallets and tokens with GoPlus Security data, plus sanctions screening for EVM wallets. 14 EVM chains, Solana, Sui and TRON. - **compare_addresses**: compares two addresses character by character to catch address poisoning. Runs locally. Network access is limited to an allowlist of HTTPS hosts. Results are automated risk assessments, not guarantees: every result lists what was not checked.

Market forecasts with their own track record, inside Claude, ChatGPT and other MCP apps. Kunkafa's MCP server lets AI apps answer market questions with calibrated numbers instead of guesses: possible moves in both directions for US stocks and indices, crypto, gold, oil and currencies, Kunkafa's confidence in each, and the record of how often forecasts at that confidence were right, wrong calls included. Durations run from five minutes to seven years. **Tools:** `list_markets`, `get_outlooks` (current forecasts for one market, filtered by duration, direction, confidence or target), `get_performance` (how often past forecasts touched their target, by confidence level and period), `get_results`, `get_usage`, `get_glossary`, `get_account_links`; `follow_market` and `unfollow_market` need the `following:write` permission. **Sign-in:** OAuth with a Kunkafa account; the free plan works. Read-only by default. Kunkafa never tells anyone to buy or sell. Probability, not advice. Docs: https://kunkafa.com/developers/setup

By loadster

Its public remote MCP server exposes typed tools for audits, results, planning, and Customer Zero evidence.

By balladic

Work data synthesizer and project tracking platform seeking to close the gap between work and the people who care about it - giving every audience, from craftsman to business layer, a complete view without information losing nuance across boundaries. It shapes itself to how people already work through modular augments, deep natural language processing for automated distillation of information, automated workflows, and adaptive interfaces, rather than imposing process.

By opula

Opula is an analyst that only looks at your money. You describe what you own in plain language, then ask: why your portfolio moved, what your effective exposure is after looking through your ETFs, how concentrated you actually are, or when work becomes optional. Opula has its own chat, so you can ask there directly. This connector adds a second way in: connect it and you can ask the same questions from Claude or ChatGPT. Same holdings, same math, same numbers wherever you ask. Every figure is computed server-side by deterministic rules rather than generated by the model, so the same question returns the same number. There is no bank linking and no API keys to set up: sign in with Google and connect in one step. Financial data is isolated per user at the database level (Postgres RLS). Built for real multi-currency portfolios: stocks, ETFs, crypto, real estate and cash across USD, KRW, JPY and more, covering 47 asset types and 9 exchanges, including assets a bank cannot sync such as 전세 (jeonse) deposits, unlisted equity and KRX gold. New accounts start on a 14-day Pro trial with 30 questions a day, no card required. After that, Free covers 3 questions a day and Pro is $9.99/month (or $99/year) for 100. Recording, edits and drill-downs never count against either plan, and no analysis is locked behind a paywall.

By csitte

A reliable, **native** Gmail MCP server for inbox triage — full mailbox control, with **no send tools by design**. Runs locally against the **live** Gmail API: no mailbox mirror, no cache, no cloud copy of your mail. Every call goes straight to Google, and the only local state is your own OAuth token in `~/.mailwarden/`. ### What it does - **Mailbox-side snooze** — archive a thread now, have it resurface in the inbox on a date or time. Built on dated labels plus a sweep, so it works from any client, is visible in Gmail itself, and survives restarts. - **Search you can trust** — Gmail's own index silently drops `is:unread` in some operator combinations; every hit is re-verified against its live labels before a tool sees it. - **Triage digest and signals** — sender / label / age buckets, plus per-thread flags (newsletter, automated, calendar, reply-to mismatch) read from headers and MIME structure, never guessed from wording. - **Bulk operations with a dry run** — `bulk_modify`, `bulk_unsubscribe` and `sweep_snoozed` rehearse the identical path and stop before the first write or outbound request. - **Unsubscribe** — per-sender overview and RFC 8058 one-click opt-out. The URL comes from the message's own `List-Unsubscribe` header and is never a tool parameter. - **Least privilege** — tool tiers (`read` / `manage` / `filters`) decide both the registered tools and the OAuth scopes requested. A `read` deployment can change nothing and makes no outbound request at all. ### Deliberately missing There is no compose, reply, forward or send tool, and `create_filter` never produces a forwarding rule — so a prompt-injected mail has no exfiltration path. Nothing is deleted permanently either: trash and untrash only. ### Setup One-time consent to **your own** Google Cloud OAuth client; the refresh token stays on your machine: ``` npx -y mailwarden --auth # one-time consent npx -y mailwarden --check # diagnose the setup ``` Full guide: https://github.com/csitte/mailwarden/blob/main/docs/SETUP.md — threat model: https://github.com/csitte/mailwarden/blob/main/SECURITY.md

By wolfendentheo

Majority vote among LLM agents fails on disputed questions because agents trained on overlapping data share systematic blind spots, they are not the independent voters... When agents do decide together, the decision process is invisible. Quorum is a complete primitive: algorithm, plus state, plus provenance. 7 Tools. 1. *register*— OPTIONAL one-time setup -- only needed if you want proposal telemetry (OTLP spans) pushed to your Telinea account. Call once before propose: it binds an api_key you choose to your Telinea API key. Afterwards, pass the same api_key on propose and every span for that proposal is pushed to your Telinea with standard OTLP bearer auth. Storage: the Telinea key is sealed with AES-256-GCM under a key derived from your api_key (HKDF-SHA256, per-account salt); only sha256(api_key) is kept as the lookup id, so neither key is ever stored in the clear. Skip this tool entirely for anonymous use, propose works without an api_key, just with no span streaming. 2. *propose* — open a proposal: api_key (from register), name (becomes the proposal id), question, voters (expected identities), deadline_minutes. Optional: options (default ["yes","no"]), algorithm (default approval), quorum (min % of voters, default 100), threshold (supermajority share, default 66.67), description. Returns the proposal id, creation attestation id, deadline, and blackboard URI. 3. *write* — append key/value to the proposal's blackboard, with optional author. Writes are appended, never replaced — the full ordered history is preserved and attested. 4. *read* — read the blackboard: every write in order with timestamp, author, and attestation id. Optional key filter. The deliberation record before voting. 5. *vote* — submit a ballot from an expected voter identity, with optional reasoning (stored in the attested record, never affects the outcome). Ballot shape depends on the algorithm — see below. Duplicate votes and post-deadline votes are rejected with structured errors. 6. *resolve* — apply the algorithm and attest the outcome. Callable once quorum is met (or after the deadline); also fires automatically when the deadline passes with quorum. Idempotent. Condorcet cycles and missed supermajority thresholds return co_winners with status unresolved, genuine ambiguity is surfaced, never hidden. 7. *history* — the complete attested record: creation, every write, every vote with reasoning, the outcome. Optional filter: all | writes | votes | outcome. The compliance artifact. *Disclaimer:* Implementers are responsible for what they put in payloads. Usage in production systems is at the implementer's risk.
