A portfolio layer
for agents.

Murre gives agents one system for research, portfolio construction, monitoring, and guarded execution. The account, mandate, session limits, and venue credentials remain outside the model.

One portfolio layer · two planes

A full portfolio loop with a hard execution boundary.

Murre is growing into the layer an agent calls to understand a portfolio, form a view, build targets, watch risk, and act. The mandate is the foundation that keeps that broader loop under operator-defined authority.

01Intelligence plane

Operate the portfolio.

Agents and deterministic models bring evidence into the system, form views, construct target books, and watch the portfolio between decisions.

  • Research and account-aware context
  • Portfolio construction and rebalance proposals
  • Drift, event, and order-state monitoring
Growing surface · never receives venue credentials
02Authority plane

Keep the operator in control.

A deterministic engine evaluates the portfolio, binds approval to the exact order, and gives the credentialed relay only the authority that survived policy.

  • Fixed account, policy, and session ceilings
  • Single-use exact-order execution permits
  • Replay protection and inspectable receipts
Foundation · enforced by the current runtime

The portfolio layer

Research, construct, monitor, execute.

The goal is one callable layer for the full portfolio loop. Some capabilities work today; others are being built in public behind the same operator-controlled boundary.

01
RESEARCH

Bring evidence into the decision.

Connect market, asset, and account context so an agent can explain what it sees before it proposes a position.

Early workflow · adapters next
02
CONSTRUCTION

Turn views into a portfolio.

Translate scores and target weights into bounded rebalance proposals that still pass through the same policy kernel.

Paper cycle · working
03
MONITORING

Keep the book tied to reality.

Read status and event history, track remaining authority, surface drift, and reconcile the next decision against fresh state.

Status + ledger · reconciliation next
04
EXECUTION

Route only the exact allowed action.

Review the order, consume its permit, and submit through Robinhood MCP without exposing the account or credentials to the agent.

The foundation

The mandate is where Murre starts.

It is not the whole product. It is the part that lets research, construction, monitoring, and execution share one system without giving the calling model unchecked authority. Agents submit intents; Murre returns a denial or a permit bound to the exact action.

01

One execution pathThe credentialed relay is the only component allowed to reach the venue.

02

Order-bound authorityChange the amount, asset, price, account, or route and the permit becomes invalid.

03

Inspectable proofEvery approval, denial, fill, and revocation becomes a replayable receipt.

Asset coverage

One book. Different proofs.

Every asset class needs its own eligibility and settlement evidence. Murre should share one authorization model without pretending the underlying assets are interchangeable.

Public + tokenized equities

The current guarded bridge supports long public-equity limit orders. Canonical token contracts, jurisdiction, market status, and settlement evidence come next.

Private assets

Issuer authority, investor eligibility, transfer restrictions, valuation age, custody, and exit liquidity.

Policy research

Real-world assets

Issuer, reserves, redemption terms, custody, maturity, settlement route, and independent attestations.

Policy research

Robinhood MCP is available as an experimental, explicitly armed equity-order adapter. Robinhood Chain registry and settlement adapters remain future work. Murre is independent and not affiliated with Robinhood. Availability and eligibility vary by jurisdiction.

Build status

Working now.
Expanding deliberately.

Murre is already callable infrastructure for policy, paper portfolios, event history, and guarded Robinhood execution. The broader portfolio layer is being added without pretending planned features are live.

  1. Working
    Callable MCP + deterministic portfolio kernel

    Status, policy checks, paper orders, target-weight cycles, hash-chained events, and single-use exact-order permits.

    Built
  2. Routing
    Guarded Robinhood MCP bridge

    OAuth, tool discovery, bounded agent calls, pre-trade review, fresh-state replay protection, and submission receipts.

  3. Building
    Research, state, and monitoring adapters

    Venue-derived snapshots, market and asset context, drift signals, order reconciliation, alerts, and a durable service boundary.

    Next
  4. Expanding
    Portfolio construction + broader assets

    Richer allocation workflows, Robinhood Chain registry and settlement adapters, private assets, and real-world assets.
