# LSEG — AI Connector LSEG publishes 20 MCP tools to Claude and is listed in the ChatGPT apps directory. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/lseg/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # LSEG Institutional market data and analytics through natural language Listed in ChatGPT and Claude · 20 published tools · Verified partner [ChatGPT listing](https://chatgpt.com/plugins/lseg?open_in_app) [Claude connector docs](https://www.lseg.com/en/solutions/ai-finance-solutions/anthropic) [lseg.com](https://www.lseg.com/) Overview ## What LSEG does The LSEG connector opens the exchange group's financial market data to a chat interface. Coverage is described as real time and spanning asset classes and domains, with analytics and valuation tools reachable through ordinary questions instead of a query language. Examples in the listing run from spot prices on the most heavily traded currency crosses, to IBES estimates for named London listings over the next two years, to daily price summaries for a single stock across the previous month. The combination is the point: instruments can be looked up and also analysed, including calculations that would otherwise sit in a separate terminal workflow. ### Who it is for Analysts and traders at firms with LSEG data access who want to query it conversationally. ### What stands out It pairs instrument lookup with valuation and calculation rather than returning figures alone. Availability ## Where LSEG is listed LSEG ships this on both marketplaces: LSEG is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain. Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

The median Claude-listed connector filed under Finance publishes 12, so this one runs 8 tools above its bucket's median and ranks 46th of 159 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. LSEG 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 LSEG Verification Verified partner (37.8% of the Claude directory) Filed under Financial Services Endpoint `https://api.analytics.lseg.com/lfa/mcp/server-cl` Documentation [Publisher setup docs](https://www.lseg.com/en/solutions/ai-finance-solutions/anthropic) Published tools 20 · 11-20 tools band Depth rank in Finance 46 of 159 Snapshot August 2026 LSEG carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How LSEG describes it > The LSEG Connector provides real-time access to LSEG's comprehensive financial market data ecosystem, spanning across asset classes and domains. It enables seamless integration of institutional-grade market data, analytics, and valuation tools directly into conversational AI workflows, allowing users to access deep market insights, perform complex calculations, and analyze financial instruments through natural language interactions.
