# Haystack — AI Connector Haystack publishes 1 MCP tool to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/haystack/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # Haystack Search a Haystack workspace for people, teams and internal knowledge Listed in Claude · 1 published tool · Community-listed [Claude connector docs](https://docs.google.com/document/d/1BMsqOe3OlHKCFOcHaeSQYWkXmUTemj1tqdkWRRj5LDk/edit?usp=sharing) [haystackteam.com](https://haystackteam.com/) Overview ## What Haystack does Haystack is an employee directory and internal knowledge workspace spanning people, teams, events, posts, knowledge pages, files, links and glossary terms. The connector adds a search entry point over that content, returning only items the connected account is already permitted to see and linking back into Haystack for the full record. The listing is explicit about the boundaries: the integration is optional, connects over OAuth, does not widen existing access controls, and the content is not used for model training. One tool is published, an unusually small figure for a workspace covering eight content types. Community tier applies, with documentation published alongside the endpoint. ### Who it is for Internal communications and people operations teams at companies running Haystack. ### Tool surface One published tool against eight content types points at a single search primitive rather than a tool per resource, though the credential gate leaves that as an inference from the count. Availability ## Where Haystack is listed Haystack is listed in the Claude connectors directory only. Haystack Team Inc 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 Haystack publishes 1 tool to Claude, a deliberately narrow surface; only 0.7% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Productivity publishes 12, so this one sits 11 tools below its bucket's median, 439th of 462. It falls in the 1-3 tools band, which holds 16.4% of the Claude directory. Haystack 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 Haystack Team Inc Verification Community-listed (61.5% of the Claude directory) Filed under Productivity Endpoint `https://haystack-mcp.haystack.so/mcp` Documentation [Publisher setup docs](https://docs.google.com/document/d/1BMsqOe3OlHKCFOcHaeSQYWkXmUTemj1tqdkWRRj5LDk/edit?usp=sharing) Published tools 1 · 1-3 tools band Depth rank in Productivity 439 of 462 Snapshot August 2026 Haystack 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 Haystack Team Inc describes it > Haystack connects Claude to your company’s Haystack workspace so you can search for people, teams, posts, events, knowledge pages, glossary terms, files, and links you’re already allowed to see. Results open directly in Haystack. The integration is optional, uses secure OAuth, and respects your existing access controls — it does not expand permissions or use your content to train models.
