Who it is for
Allocators and fund-of-funds teams tracking positions across many legal entities.
Mantle Portal
Private markets positions and document extraction via Mantle Portal
Overview
What Mantle Portal does
Mantle Portal covers private markets holdings for allocators carrying positions across many funds and legal entities. The connector answers questions about fund positions and look-through exposure to the underlying portfolio companies, and derives figures from the documents those positions generate: limited partnership agreements, capital call notices and K-1s.
Answers reference the source document rather than standing alone, which is the point of the design for anyone who has to defend a number later. Eight tools are published. The audience the publisher names is endowments, pensions, family offices and general partners of fund-of-funds vehicles.
Tool surface
The endpoint refuses without giving a reason, so the eight tools remain a publisher count and the split between position queries and document extraction cannot be checked.
Availability
Where Mantle Portal is listed
Mantle Portal is listed in the Claude connectors directory only. Mantle 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
Mantle Portal publishes 8 tools to Claude. That is a mid-sized surface: 37.7% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Finance publishes 12, so this one sits 4 tools below its bucket's median, 107th of 159.
It falls in the 7-10 tools band, which holds 14.6% of the Claude directory.
Mantle Portal 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.

Mantle Portal 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.
