When an Agent Picks Your Vendor, What Should It Be Checking?
On this page
Subconscious gives a marketing agent controlled message evidence before the agent recommends a creative direction. A growth or marketing-ops team can compare complete alternatives on simulated buyers, inspect the estimated choice difference, and attach the study to a specific action. The useful handoff is a recommendation with a traceable comparison and a defined scope of authority.
River City Federal Credit Union shows why message evidence belongs in that handoff. A discrete-choice study with 140 digital twins identified a staff-proposed slogan as the weakest. The same slogan later performed worst in live Facebook and Instagram ads. That record supports the value of testing a message before commitment; it does not establish an autonomous-agent outcome or a numerical slogan-accuracy score.
Choose a research tool for the decision the agent must make
An agent selecting a tool needs more than a successful connection. A message-selection task needs complete stimuli, a defined audience, a measured response and a rule for acting on the result. A tool that generates persuasive copy serves a different job from a study that compares responses to that copy.
Anthropic's MCP announcement describes a protocol connecting models with data and tools. MCP can carry a research workflow; the host's policy determines vendor selection, retries and permitted actions.
A configured tool-selection policy can inspect:
- Task fit: require a description that makes the supported operation and limits clear.
- Schema: define parameter meanings and return values without requiring guesses.
- Authentication: use an authorized mechanism supported by the host and buyer policy; a plain API key is not universally preferable.
- Reliability: specify retries, error handling and evidence from previous executions.
- Cost: enforce the configured usage and approval limits.
Include relevant validation, supplier terms and reputation in that policy. The second diagram summarizes the operational checks; the research comparison still needs a decision-specific evidence review.
What Subconscious can connect today
The Subconscious MCP guide documents a remote connection for designing and inspecting experiments. An assistant can prepare and revise a conjoint draft, retain the run identity, and inspect available results. Discover the connected session's tools and inspect their actual schemas before making calls.
A paid experiment launch requires the client's trusted approval flow for the exact study and cost. Listing tools does not prove the client supports that flow. Inspect available analytics and their returned scales before translating results into a recommendation.
Connecting research to a campaign system remains a workflow integration to scope with the team. The research connection supplies no blanket authority to buy media or publish creative.
A message recommendation the next agent can inspect
Consider an invented brief for time-tracking software. The team wants an agent to prepare a creative brief for independent US consultants who invoice by the hour. Confirm support for the modeled audience before launch; modeled traits are not verified recruitment of working consultants.
The two hypothetical text ads differ only in the headline:
- Ad A: “Track every billable hour.”
- Ad B: “Invoice clients without chasing timesheets.”
- Shared body: “Time tracking with weekly reminders. $12 per user per month. Book a demo.”
Both ads use the same layout, placement and demo destination. The controlled message study asks which ad the respondent would open, with a neither option and controlled presentation order. The planned contrast is B's modeled choice rate minus A's. Agree an uncertainty calculation that accounts for repeated responses from the same simulated respondent.
Before seeing results, the team sets a rule: prepare B's creative brief only when the contrast's interval clears zero. Otherwise retain A or return an unresolved comparison. Preparing a brief carries no media-spend authority.
The following values are invented to demonstrate a completed handoff. No customer run or measured product result is represented.
| Handoff field | Illustrative content |
|---|---|
| Comparison | Exact ads A and B above; headline alone varies; neither remains available |
| Population and endpoint | Modeled independent US hourly consultants; choice of ad to open |
| Estimated contrast | B minus A: +4 percentage points; illustrative 95% interval: +1 to +7 points |
| Evidence reference | The completed run identity, exact stimuli, population settings, model/version and saved analysis |
| Action under the prior rule | Prepare the creative brief for B and attach the comparison |
| Authority | Draft preparation only; $0 media spend; no publication |
The positive interval selects B for the brief under that stated rule. The estimate concerns modeled ad choice. Forecasting demo bookings or revenue requires a separate connection to those outcomes and relevant market evidence.
The handoff fields are a proposed integration contract, not an asserted MCP response schema. Verify the run's actual artifacts and calculate the agreed contrast before populating the record. A utility distribution must not be relabeled as the effect interval above.
Match the action to the evidence and authority
The growth lead can now approve a concrete workflow: generate candidates, run the agreed comparison, retain the evidence, and prepare the permitted brief. Evidence that remains unresolved routes back to the comparison step. An agent cannot enlarge an action's authority because a study looks favorable.
Human approval of a paid run or campaign release is an authorization control. A fresh study with human participants is a research choice for a specified uncertainty. Those controls serve different purposes; the buyer should configure each where the intended decision requires it.
Bring the proposed agent workflow, complete message alternatives, audience, measured response and action limits to a Subconscious decision review. Agree the research output and receiving system before connecting the recommendation to a live campaign.
