# Kastra — AI Connector Kastra publishes 13 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/developer-tools/kastra/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Developer Tools](https://node8.ai/ai-connectors/developer-tools/) # Kastra Read-only view of AI agent authorization decisions and audit trails Listed in Claude · 13 published tools · Community-listed [Claude connector docs](https://kastra.ai/mcp) [kastra.ai](https://kastra.ai/) Overview ## What Kastra does Kastra evaluates agent actions against written policy and keeps a tamper-evident record of what was allowed, denied, or held. The connector is deliberately one-directional. After OAuth consent and the selection of a single environment, it can read decisions and their outcomes, policies and per-rule statistics, incidents and pending approval checkpoints, audit-chain verification results, activity trends, and masked API key metadata. What it cannot do is written into the listing: no writes, no settings changes, no reach into another tenant, and no exposure of raw prompt content or plaintext keys. Thirteen tools are published, access stays scoped to the selected environment, and it can be revoked from connector settings. ### Who it is for Security and compliance owners accountable for how autonomous agents behave. ### Tool surface Nothing can be enumerated from outside, since the server requires the OAuth grant before it responds, so the read-only characterisation of its thirteen tools rests on the publisher's description. Availability ## Where Kastra is listed Kastra is listed in the Claude connectors directory only. Kastra Labs has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Kastra publishes 13 tools to Claude. That is a mid-sized surface: 54.3% of the 1,253 Claude-listed connectors expose fewer. That is exactly the median for Claude-listed connectors under Developer Tools, where 95 publish counts and 13 is the middle of the distribution. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. Kastra publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Kastra Labs Verification Community-listed (61.5% of the Claude directory) Filed under Developer Tools Endpoint `https://api.kastra.ai/mcp/account` Documentation [Publisher setup docs](https://kastra.ai/mcp) Published tools 13 · 11-20 tools band Depth rank in Developer Tools 48 of 95 Snapshot August 2026 Kastra is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Kastra Labs describes it > Kastra is an AI authorization platform that evaluates your AI agents’ actions against your policies and maintains a tamper-evident audit trail. This connector gives Claude read-only access to your Kastra account, allowing you to ask questions about your governance posture in plain language instead of navigating the console. After you authorize the connector through a Kastra OAuth consent screen and select an environment, Claude can read—but never modify—the following: •⁠ ⁠Decisions and their outcomes (allow, deny, and hold) •⁠ ⁠Policies, environments, and per-rule statistics •⁠ ⁠Incidents and HOLD approval checkpoints •⁠ ⁠Audit-chain verification results and governance audit logs •⁠ ⁠Activity statistics and trends •⁠ ⁠Onboarding governance preferences and masked API key metadata Access is limited to your tenant and the specific environment you select during authorization. The connector cannot write data, modify settings, access other tenants, or expose raw prompt content or plaintext API keys. You can revoke access at any time through your connector settings.
