Klisten TokenIsolate

Klisten TokenIsolate

By Klisten Inc

Register a supplied target rule with allowed or denied sensitive-data categories and redaction preferences. Returns the validated local routing rule; it does not configure a network proxy or enforce controls in another system. List this organization's registered sensitive-data route rules and their targets, categories and enabled states. Returns local policy definitions; it does not discover or audit external network policies. Scan supplied text for supported sensitive-data categories with optional category and confidence filters. Returns matched spans, categories and confidence estimates; pattern detection is local and does not guarantee exhaustive privacy protection. Detect supported sensitive-data spans in supplied text and replace them with token placeholders while storing originals in this organization's recovery vault. Returns redacted text and tokens; redaction is reversible and is not irreversible anonymization. Evaluate a supplied target and text against local sensitive-data route rules. Returns ALLOW or DENY with matched categories and redaction preference; it does not block network traffic or forward the text to another system. Scan supplied flow-stage payloads and record local audit events with exposure categories and text hashes. Returns exposed stages, finding counts and CLEAN or EXPOSED status; it does not observe a live pipeline or intercept traffic. Look up a supplied recovery token in this organization's sensitive-data vault. Returns the original value and category if found, or an unsuccessful lookup; this reveals previously stored sensitive content and does not query an external vault. Compare a supplied candidate value with the hash stored for a local recovery token. Returns whether it matches, its category and the original only on a successful match; it does not validate an external identity or authentication credential. Pass supplied text and local pattern findings to the configured local classi

Klisten ToolGuard

Klisten ToolGuard

By Klisten Inc

Klisten ToolGuard connects Claude to your Klisten account through OAuth or a dedicated API key. Request policy gate decisions for configured MCP tools and retrieve existing attestations. Available tools: - toolguard_gate_check_paid requests a decision and may debit prepaid service credits. Requires gate:check. Reuse the same idempotency key after an uncertain request. - toolguard_attestation_get retrieves an organization-visible signed envelope and revocation status. Requires attestations:read. Grant only needed permissions and set account/key spending limits. Gate checks require sufficient balance and service/policy configuration. Missing or stale scan evidence can produce a charged unknown decision. Server pricing is authoritative. This connector does not create scans, execute target tools, process payments or payouts, or cryptographically verify receipt signatures. A gate decision is not a security guarantee or permission to execute an action.

Knighn

Knighn

By Lucas Knight

Knighn is a design editor for macOS and the web where each design is code. Ask Claude for an app screen, a landing page, a slide deck or a set of social images, and Claude makes a real design in your Knighn account. Open it in the Knighn app for Mac or at app.knighn.com to see it and change it by hand. A Knighn design is TSX with Tailwind classes, in one .html file that draws itself in any browser. There is no export step: the design is already code that your React or React Native project can use. The connector has two tools: - Search designs finds your designs and the screens, components and layers in them. It also finds the design guide, styles, templates, fonts and icons. - Edit a design runs a short script that makes or changes a design, then saves it. Knighn keeps the earlier version of each design, so you can go back. When the Knighn app or daemon runs on your Mac, Claude can also take screenshots of its frames and check them. Allow "Run on your Mac" when you connect to use this. You need a free Knighn account. Sign in when Claude asks, choose what Claude may do, and revoke access at any time in Knighn, Settings, Connections.

Know Who CRM

Know Who CRM

By Khiliad

KnowWho is a CRM for relationships that matter, and it runs entirely inside your AI assistant. There is no form to fill in and no app to switch to. Capture by talking. Say who you met, where, and what happened, and KnowWho records the person, their company, the conversation, any introductions made, and anything you agreed to follow up on. One sentence after a call or event is enough. Misspelled names and partial details are matched against what you already have, so you don’t create duplicates. Prepare in seconds. Before a meeting, ask about a name and get everything you know: current and former roles, who introduced you, past conversations, open tasks, and live opportunities. Ask your network questions. Who do we know at a given company? Who have I not spoken to in three months? Which opportunities are open this quarter? What did we discuss last time? Search works by name, email, or what was said, and copes with misspellings and half-remembered words. Built for founders, investors, business developers, and community builders who want their network to be something they can ask, not a database to maintain. Use it alone or share one book across a team. It is not for bulk outreach, mailing lists, or sales automation. Your data is yours. Records live in your own workspace, and you can export or delete them at any time.

KnowWho CRM

KnowWho CRM

By Khiliad Limited

KnowWho is a CRM (customer relationship management tool) for keeping track of the people and companies you work with. It stores contacts, companies, meetings, calls, notes, introductions, follow-up tasks, and sales or partnership opportunities, and lets you add and retrieve all of it by chatting. Log a meeting in one sentence. Say who you met, where, and what happened, and KnowWho records the person, their company, the conversation, any introductions made, and any follow-up you agreed. Names and partial details are matched against existing records, so duplicates are not created. Prepare for a meeting. Ask about a person or company and get their current and former roles, who introduced you, past conversations, open tasks, and open opportunities. Ask questions across your contacts. Who do we know at a given company? Who have I not spoken to in three months? Which opportunities are open this quarter? What did we discuss last time? Search works by name, email, or what was said, and copes with misspellings. Built for founders, investors, business developers, consultants, and community builders. Use it alone or share one workspace across a team. It is not for bulk email, mailing lists, or sales automation. Your data stays in your own KnowWho workspace, and you can export or delete it at any time. A KnowWho account is required.

Knowi

Knowi

By Knowi

Knowi is an AI-native business intelligence platform. This plugin connects ChatGPT and Codex to your Knowi account so you can ask questions of your data, build and update dashboards, and manage reports and alerts without leaving the conversation. What you can do: - Ask questions in plain English. Knowi resolves the right datasets, runs the query, and returns results, with a chart when one helps. - Explore what already exists: search dashboards, widgets, datasets, queries, and alerts; pull the data behind any widget; trace lineage and see how a business term was resolved. - Build: create datasources and queries (Cloud9QL or your database's native language), create and lay out widgets and dashboards, and export results to CSV or PDF. - Automate: create and test alerts, schedule and update reports, and deliver them by email, Slack, or Microsoft Teams. - Manage the semantic layer: define, map, and publish glossary terms so questions resolve consistently across your team. - Work with documents: ingest PDFs, Word, Excel, CSV, and images, ask questions about their contents, and extract structured data from them. Every tool runs as you, so data access follows your Knowi role and asset permissions. Tools that create, modify, or delete Knowi assets are marked as write or destructive, so the assistant confirms before making changes; read-only tools run without prompts. Requirements: a Knowi account. Sign in with OAuth when you connect; there are no API keys to copy.

Knowra

Knowra

By Knowra

Knowra helps researchers find relevant arXiv papers and decide where to spend their reading time, directly in Claude. Search papers by research question, keywords, authors or date range. Knowra searches indexed arXiv titles, authors and abstracts, and supports exact UTC date windows of up to one calendar month, so Claude can look at only the papers from a specific day, week or month. For papers that look promising, Claude can read a Scout report. Scout is generated from the full paper and lays out the key findings, methods, experimental conditions, evidence, verification points and stated limitations. Figures are described through their captions and text descriptions. Scout is a screening aid: it helps rule out papers that do not fit your setting and points to what you should check in the original paper. It is not a substitute for reading the paper or for peer review. Tools - Search papers: search arXiv titles, authors and abstracts, with optional date filters. Available without signing in. - Get Scout report: read the Scout report for a paper returned by search. Requires a Knowra account. - Get usage: check your Scout allowance, usage and reset time. Requires a Knowra account. Access - Search is free, with no daily search quota (rate limited per IP). - Free Knowra accounts include 5 first-time Scout unlocks per UTC day. Reading a paper you have already unlocked is free. - Pro accounts include 500 first-time Scout unlocks per month. - Your Knowra account, allowance and unlocked papers are shared across the Knowra app, website and this connector. Knowra only receives the tool requests Claude sends, not your conversation history. See https://knowra.app/privacy for details.
