Who it is for
Self-directed traders keeping an auditable journal alongside brokerage activity.
Slatemark
Delayed market data, trade journal and brokerage records, read-only
Overview
What Slatemark does
Slatemark keeps the record behind a trade rather than generating signals. The connector reaches market data delayed by roughly fifteen minutes; delayed option-chain snapshots with technical analytics; primary-source series covering macro, Treasury, energy, SEC filings, factor and positioning data; and a trade journal holding the thesis, rules, tags and notes entered beside a recorded outcome.
Authorized brokerage connections supply periodically synced balances, positions, orders and activity, which the publisher takes care to distinguish from market data. Results carry source, fetch time and freshness fields. A Strategy Scorecard describes patterns across closed trades without forecasting future ones. Eighty-seven tools are published. Slatemark cannot place, modify or cancel orders or move money, and states it is not an adviser or broker-dealer.
Tool surface
Eighty-seven tools are claimed, one of the largest counts in this category, and the endpoint refuses an uncredentialed listing, so the read-only construction the publisher describes rests on that statement alone.
Availability
Where Slatemark is listed
Slatemark is listed in the Claude connectors directory only. PD&A LLC 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
Slatemark publishes 87 tools to Claude, a deeper surface than 97.1% of the 1,253 Claude-listed connectors, the top decile.
The median Claude-listed connector filed under Finance publishes 12, so this one runs 75 tools above its bucket's median and ranks 6th of 159 by tool count.
It falls in the 51+ tools band, which holds 9.6% of the Claude directory.
Slatemark 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.

Slatemark 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 PD&A LLC describes it
Slatemark gives Claude a read-only record behind each trade. Its MCP tools connect Claude to market data delayed by approximately 15 minutes; delayed option-chain snapshots and technical analytics; primary-source macro, SEC filing, Treasury, energy, factor, and positioning data; your trade journal and framework rules; and authorized brokerage Account Data. Brokerage connections provide periodically synced balances, positions, orders, and activity, not market data. Tool results include source, fetch time, freshness, and related provenance where available. Claude creates the response and decides how to present those fields; Slatemark hosts no model. The journal keeps the thesis, rules, tags, and notes you enter beside the recorded outcome. Available brokerage activity can be reconciled periodically while manual and broker-derived facts remain distinct. The Strategy Scorecard describes patterns across your own closed trades; it does not forecast future results. The plugin also bundles an optional senior-analyst skill to help Claude use the tools and compare facts with your recorded rules. Slatemark is read-only by construction. It cannot place, modify, or cancel orders, move money, or change a brokerage account, and it does not tell you what to trade. Slatemark does not provide investment advice or serve as a registered investment adviser, broker-dealer, financial planner, or fiduciary. A Slatemark account is required. Free includes the trade journal, framework rules, Strategy Scorecard, delayed market data, primary-source research, and one read-only MCP connection. Plus adds brokerage Account Data and periodic activity reconciliation; Pro adds premium news, earnings, and estimates under your own keys.
