Crystal

Personality AI

Your agents know the task. Now they can know the person.

The Crystal MCP server gives agents and assistants the missing people layer: who they are talking to, how that person communicates, and how to adapt the next message, call, or meeting to match.

The difference

Same intent, adapted to the person.

Generic AI gives everyone the same answer. An agent with Crystal context delivers the same message two different ways, because the two people reading it could not be more different.

One intent

Follow up after the pilot and move toward a rollout decision.

Direct · Results-first

Maya, bottom line: the pilot cut onboarding time 40%. Two rollout options attached. Can you pick one by Friday?

Why it works: Leads with the result, offers a decision, sets a deadline. No warm-up.

Steady · Relationship-first

Hi Sam, thanks for the thoughtful questions last week. The pilot went well, and I wrote up how the rollout would work step by step, so nothing changes for your team overnight.

Why it works: Opens with the relationship, reassures about change, walks through steps.

What your agent gets

Four abilities, one connection.

Connect once and every workflow downstream inherits the people layer. These are tools the agent calls on its own, mid-task, whenever a person enters the picture.

  1. 01

    Identify anyone mid-task

    search

    Your agent resolves a real person from an email address or LinkedIn URL while it works: no manual lookup, no copy-paste, no separate tab.

  2. 02

    Understand how they communicate

    fetch

    Each profile carries DISC, MBTI, and Enneagram context plus concrete communication guidance: pace, detail level, what builds trust, what creates friction.

  3. 03

    Adapt the output, not just the data

    adapt

    The agent rewrites the email, call script, or talk track for that specific person. Same intent, different delivery, grounded in the profile instead of a guess.

  4. 04

    Prepare for the room, not just the person

    meetings

    Pull upcoming meetings and get group guidance built from every attendee’s personality: where styles will clash, who needs detail, who needs the bottom line.

Where it runs

Built for agents that talk to people.

  • Sales agents

    Outreach, objection handling, and follow-ups tuned to how each buyer decides.

  • Support

    Responses that match the customer’s patience, detail tolerance, and tone.

  • Recruiting

    Candidate outreach that lands on the first touch instead of the third.

  • Customer success

    Renewal and expansion conversations framed for the stakeholder reading them.

  • Voice agents

    Live calls that adjust pacing and directness to the person on the line.

  • Meeting follow-up

    Recaps and next steps written the way each attendee actually reads them.

For developers

An API your coding agent can wire up.

Four endpoints, bearer-token auth, typed responses. Use guidance-only mode to keep your own model in charge, or let Crystal generate the adapted output directly. The implementation guide ships with a drop-in prompt for your coding agent.

POST /v1/adapt/email

Adapt a drafted email with Crystal communication guidance.

POST /v1/adapt/prompt

Generate guidance to inject into your own AI workflow. Bring your model, keep your stack.

POST /v1/adapt/call-script

Generate a call script adapted to the person being called.

POST /v1/prepare/meeting

Attendee-level communication prep for an upcoming meeting.
