Clay MCP for Reps vs. Agent Plugin

Clay gives you two ways to work with your workspace outside the Clay app. MCP for Reps brings Clay's data and your team's approved workflows into the AI tools sellers already use, and the Clay Agent Plugin gives builders Clay's skills and the clay CLI inside their coding agent.

Choosing between them

The reliable signal is the person's job, not which surface is more capable.

• They run plays other people built. MCP for Reps. The rep prompts in their AI tool, and what they can reach is what your ops team approved.
• They build the plays. The Clay Agent Plugin. It puts Clay's skills and the clay CLI in their coding agent, so they can compose new logic rather than only invoke it.
• They need Clay inside a backend job, internal tool, or product feature. The Public API, which comes with the plugin, rather than either interactive surface.

One thing trips people up here: the AI tool someone is sitting in doesn't settle it. MCP for Reps connects from coding agents as well as chat apps, so a rep and a GTM engineer can both be working in Claude Code and still need different surfaces.

MCP for Reps

MCP for Reps is the access layer that brings Clay's workflows and go-to-market context into the AI tools reps already use. Setup has two halves: an admin enables access, invites each rep, and chooses which Functions and credit budget they get, and each rep then adds the connection in their own AI tool. You can get started at clay.com/mcp.

What reps do with it:

• Prospect net-new leads with a reason to reach out attached to each one.
• Ask account questions in natural language instead of assembling the answer across several tools.
• Draft outreach grounded in enrichment data rather than in whatever the model already knows.
• Prepare for meetings with a briefing per account.
• Run a Function your ops team built from a single prompt.

Where to go next:

• MCP in Clay — the admin side: permission types, credit budgets, Functions, and the Audiences controls.
• Connect to Clay MCP — what to send reps so they can add the connection themselves.
• Roles and permissions — what the Sales rep permission type can and can't reach.
• MCP security and privacy — how workspace data is handled once a rep connects.
• MCP — Troubleshooting & FAQ — connection errors and Function configuration problems.
• Courses for both sides: Clay MCPs for reps and Clay MCP for ops.

The Clay Agent Plugin

The Clay Agent Plugin is a headless way to build in Clay. It installs Clay's skills and the clay CLI into your coding agent, so you can create and run enrichment and end-to-end workflows without opening the Clay app — and results land back in Clay, where the rest of your team can see them. You can get started at clay.com/agent-plugin.

What builders do with it:

• Source a total addressable market across 200+ data providers, with waterfall logic validating emails and phone numbers.
• Build prospect lists that call your existing functions, Workflows, and Claygents, so the agent reuses centrally governed logic instead of rebuilding one-offs.
• Automate workflows described in natural language, with run observability staying in the Clay app.
• Read and segment Audiences — your workspace's own people, companies, and deals — from the terminal.
• Wire Clay into a backend job, internal tool, or product feature using the Public API and a Clay API key.

A few boundaries are worth knowing before you plan around the plugin:

• The CLI reads and segments Audiences rather than writing to it, so there's no command that sets a field value on a record, imports records, or uploads a CSV.
• Campaigns stay in the Clay app — the plugin won't launch, pause, or resume one.
• clay tables query reads data that already exists in known Clay tables, and it needs API table sync, which is an Enterprise feature.
• Mac and Linux are supported. Windows isn't yet.

Where to go next:

• Clay Agent Plugin (API & CLI) — install, sign-in, and the per-plan search limits.
• developers.clay.com — the CLI quickstart, Public API setup, code examples, and guides for Searches, Routines, and Workflows.
• CLI security and privacy — how the CLI handles your credentials and data.
• Audiences for agents and the CLI — the clay audiences command reference.

FAQs

What happens if someone has both connected in the same coding agent?

The two surfaces expose overlapping tools, so an agent with both connected can reach for the wrong one — calling a rep search when the clay CLI was the better fit for the job. The plugin ships instructions telling the agent to leave the rep tools alone, so the plugin's own path wins where they overlap. They aren't designed to run side by side, though, so it's cleaner to give each person only the surface their work needs.

If the plugin can do more, why would a rep use MCP for Reps?

Capability isn't the deciding factor — governance is. The plugin gives a person their own Clay access, so they can build new logic as well as run it, and nothing narrows which logic they reach for. MCP for Reps inverts that: your ops team builds and approves the logic, and the rep runs it from a prompt.

Ops also gets to shape what that logic costs. A Function can check your CRM for a phone number before it spends anything on a vendor, and reps calling it inherit that decision without having to know it was made.

Can a rep build their own Function?

No — Functions are built in the Clay app by someone with workspace access, then exposed to reps by turning on the function's MCP for reps surface. That's the split the rep surface is designed around: your ops team decides what the logic does, and reps decide when to run it. If the person asking wants to build the logic themselves, they want the plugin, and they'll need more than the Sales rep permission type.

Which one gives us tighter control over credit spend?

MCP for Reps. An admin sets a monthly credit budget per rep from Settings → MCP users, and a rep who reaches their cap is blocked until the next reset, which an admin can lift by raising the limit. The plugin doesn't carry per-person credit budgets; you see consumption after the fact from the Runs view in Workflows.

Neither surface adds a surcharge. Work costs the same credits and actions as the equivalent work done in the Clay app.

Do we have to pick one for the whole workspace?

No — both are assigned per person. You give the Sales rep permission type to the people who should have MCP-only access, and anyone with their own Clay access can install the plugin. Plenty of teams run both, with ops and GTM engineers on the plugin and the sellers they support on MCP for Reps.
