LSEG and Microsoft bring LSEG-licensed financial data to Microsoft 365 Copilot via MCP
LONDON and REDMOND, Wash. - Oct. 13, 2025 - LSEG and Microsoft announced the next step in their multiyear partnership: enabling agentic AI in Microsoft 365 Copilot to work with LSEG-licensed data through an LSEG-managed Model Context Protocol (MCP) server. This gives finance teams secure, governed access to trusted market data directly inside Microsoft workflows.
The move connects LSEG's AI Ready Content and analytics with Copilot Studio's agent-building capabilities. The result: faster decisions, cleaner execution, and lower integration overhead for firms that need dependable data in their day-to-day tools.
What this means for finance teams
- Build AI agents in Copilot Studio that can use LSEG data licensed through products like Workspace and Financial Analytics.
- Keep data secure with enterprise-grade governance, permissioning and compliance aligned to Microsoft 365 controls.
- Reduce integration costs by using an open protocol that standardizes how LLMs and apps access LSEG data.
- Ship AI-enabled research, risk, and sales workflows faster without rebuilding core data plumbing.
How it works
An LSEG-managed MCP server connects Copilot Studio to LSEG APIs and can interoperate with customers' internal AI systems and third-party applications. MCP provides a standardized way to pass tools, data and actions to agents so LLMs can interpret and use LSEG content effectively.
With Copilot Studio, makers can compose agents by combining policies, prompts, tools and actions, then deploy them into Microsoft 365 Copilot and other applications. Governance is built in, so admins can scale usage with clear controls and auditability.

Data depth that moves markets
LSEG's AI Ready Content spans more than 33 petabytes across decades of history, supported by rich taxonomies and identifiers. Bringing this depth into Copilot means analysts, PMs and bankers can blend human judgment with LLM reasoning using reliable, permissioned data inside their daily tools.
LSEG data access via MCP will roll out in phases, starting with LSEG Financial Analytics.
Practical use cases
- Research: Generate first-draft summaries with linked sources from LSEG content, then refine with desk-specific prompts and policies.
- Portfolio and risk: Ask agents for factor exposures, liquidity snapshots and event-driven impacts using licensed analytics.
- Sales and trading: Build pre-trade briefs and client-ready notes with real-time context, entitlements and disclosures.
- IB and ECM/DCM: Prepare earnings and deal prep materials drawing on historicals, comps and market activity.
- Compliance: Enforce usage and audit policies in Microsoft 365 while keeping data flows standardized via MCP.
From idea to deployment: a simple path
- Confirm licenses for LSEG products such as Workspace or Financial Analytics.
- Connect Copilot Studio to the LSEG-managed MCP endpoint and configure entitlements.
- Compose agents using policies, prompts, tools and actions mapped to your workflows.
- Validate governance with Microsoft 365 controls (DLP, RBAC, audit) before wider rollout.
- Deploy into Microsoft 365 Copilot for use in Outlook, Teams, Word and Excel.
Why MCP matters
MCP enables consistent, secure connectivity between agents and data across vendors. For enterprises, that means fewer custom integrations, less technical debt and faster delivery of AI-enabled workflows that can interoperate with both LSEG APIs and internal systems.
