Practical guide
Build a GTM agent with Claude and your CRM context
Start with an opportunity your team already understands. Ask Claude to read the history, identify the missing decision and prepare the next step. Keep the first version small enough to inspect.
How do you build a GTM agent with Claude?
Define one revenue task, connect Claude to the CRM through MCP, give it the relevant account or deal and set clear rules for reading, drafting and writing. Start by reviewing its evidence and proposed actions. Add confirmed CRM writes only after checking the available tools and permissions. An interactive Claude workflow is not automatically an unattended agent.
1. Choose one opportunity and one useful output
Use a test opportunity or a record you are authorized to access. The goal is to prepare a follow-up on an open proposal, not to research a whole market or contact every lead. Choose an opportunity with a recent conversation and a known next decision.
You will need a Lumenbase workspace, access to the record and a Claude client that supports an MCP connection. The tools you can use depend on the authenticated connection. A paid plan, client policy or workspace setting may affect access.
2. Connect Claude to Lumenbase over MCP
Follow the current Lumenbase connection guide for your client. Use the hosted connector flow or the documented personal-token setup for a compatible MCP client. Keep credentials in the client's connection settings, not in a prompt or a shared note.
Begin with a read: ask Claude to list the CRM tools available to this connection, then find the test opportunity and return its exact identity. If it cannot access the record, resolve the permission or connection issue before continuing.
3. Give the agent a task contract
The prompt below defines the outcome and limits. Replace the bracketed record reference with your test deal. It intentionally does not prescribe tool names or request shapes; those should come from the connected tool catalog.
Review the open opportunity [deal name or ID] in Lumenbase. First confirm the exact deal and company. Read the available conversation history, meeting notes and outstanding tasks. Return: 1. The buyer's last stated requirement, with a record or thread reference. 2. The decision or information still missing. 3. A short follow-up draft based only on that evidence. 4. A proposed next-step task with an owner and a suggested due date for me to review. Do not send a message, create a task, edit a note or change a deal stage. Do not guess a budget, delivery date, promise or person's role. Respect any request to pause contact. If evidence is missing or contradictory, explain what needs checking instead. Stop after showing the evidence, draft and proposed task.
4. Check the evidence before confirming a write
Open the source conversation yourself. Check the identity, timing and buyer request. A plausible summary is not enough: the action must fit what the buyer actually said.
If the connection exposes a supported task-creation tool, confirm one task using the reviewed owner and due date. Tell Claude exactly which action you approve and keep unrelated actions out of scope. Re-open the CRM record to verify the task landed on the right opportunity. Approval of a task is not approval to send the draft.
- The proposed due date is appropriate and explicit.
- The owner is a real, permitted workspace member.
- The task is attached to the intended record.
- Re-running the workflow will not create a duplicate task.
- The message remains a draft until the seller separately approves sending.
5. Test the cases that should make the agent stop
Try the workflow on a record with no recent notes, two contacts with similar names and a buyer who requested a pause. A useful agent tells you which fact is missing and does not treat every quiet opportunity as permission to send.
No context
Ask for the missing conversation or next decision. Do not turn an empty record into invented personalization.
Ambiguous identity
Ask the seller to choose the exact record. Do not write to the first matching company or contact.
Denied write
Keep the proposal visible and explain that the connection cannot perform the action. Do not report a task as created.
Interrupted run
Check whether the write completed before retrying. One approved next step should produce one task.
Turn the checked workflow into a repeatable motion
This guide is a task recipe for a connected Claude session, not a benchmarked autonomous-agent implementation. A scheduled version needs a trigger, a bounded account set, usage limits, retry handling and a review path.
For native recurring work, inspect Lumo and Routines before building a separate runner. For a custom agent, keep the CRM as the system of record and verify the result of every supported write. Reuse the tested task contract instead of giving the agent an open-ended instruction to grow revenue.
