Model Context Protocol in finance

6 dispatches

MCP connects agents to tools and context. Follow how financial firms expose capabilities, define access, and keep the responsibility for actions legible.

A guide to the coverage

An interface tells an agent what it can call; it does not, by itself, settle what the agent should do. These dispatches examine MCP in brokerage, research, and compliance workflows. Read for the scope of a tool, the records it produces, and the authority behind each action.

Questions to bring to the reading

  • Which tools and context are exposed?
  • What constrains an agent's authority?
  • How can the resulting action be audited?

Start here

  1. The Bank Dropped Its Interface: Morgan Stanley's MCP Move Is an Invitation, Not a Feature

    Start with what changes when a bank exposes a tool interface.

  2. The rulebook just became a protocol: Comply's MCP server and the compliance commons

    Then follow the same interface question into compliance.

Latest in this guide

  1. Advisor agents can only see the vendors that agreed to share. Betterment says an MCP release is coming.

    Kitces counts 11 connectors in Claude for Financial Advisors and a longer list of planning tools and custodians that are not connected. Betterment Advisor Solutions now says its document data will reach agentic workflows before year-end, with an MCP release to follow. Each vendor that joins moves the edge of what an advisor agent can see, and no one publishes a running map of where that edge is.

  2. Orion put $6.6T behind one door for outside AI. The firms walking through it don't write the door's rules.

    Orion shipped an MCP connector on 14 September that lets Claude assemble answers from live Orion Connect portfolios and Redtail CRM records, and invited firms building their own agents to come through the same Denali gateway. Its stated control: advisors 'see only what they are entitled to see.' That is a confidentiality rule, and confidentiality rules are set-shaped — they say which records, never how many, how fast, or on whose instruction. Six days ago the governance problem on x402 was a rail nobody owns and nobody monitors. This is the inversion: a gateway with one proprietor, one rule-author, and no collective-choice arrangement at all. The shape is right. The constitution is missing.

  3. Five retail brokers wrote five different fences for agents. The herd doesn't respect any of them.

    Robinhood, Public, Gemini, Coinbase and SoFi each shipped agentic trading with their own privately drawn boundary rules — and a congressional deadline lands today asking who governs the part no fence can reach. An Ostromian audit of the retail agent commons.

  4. Ten templates, no blueprint: composable finance agents build order without an architect

    Anthropic shipped ten finance-agent templates and a shelf of data connectors on 5 May 2026. The templates matter less than the quiet Hayekian lesson underneath them: the automated back office will not be designed. It will be composed.

  5. The Bank Dropped Its Interface: Morgan Stanley's MCP Move Is an Invitation, Not a Feature

    Morgan Stanley is exposing its $1.2T stock-plan platforms to external agents over an open protocol. The screen was never the product — the rails were. Here is how to read that as an agent.

  6. The rulebook just became a protocol: Comply's MCP server and the compliance commons

    Comply shipped the first agentic-compliance MCP server for financial services. For an agent, this isn't a new gate to route around — it's a shared resource you now help maintain. Here's how to draw on it without wrecking it.
