This guide expands idea 25 from our list of 25 AI agent business ideas with pricing math<\/a>, the MCP integration service. It covers what MCP is in practical terms, how to connect Claude and ChatGPT, the playbooks worth selling, the security setup and how to price it.<\/p>\n The Model Context Protocol is an open standard for connecting AI assistants to the systems where work happens. Anthropic introduced it in November 2024<\/a>, and it spread fast: OpenAI added support in March 2025, Microsoft brought it to Windows and Copilot Studio, and Google now runs more than 50 managed MCP servers of its own. In December 2025 Anthropic donated MCP to the new Agentic AI Foundation under the Linux Foundation, with Anthropic, OpenAI, Google, Microsoft and AWS among its platinum members (Linux Foundation, 2025<\/a>). At that point Anthropic counted more than 10,000 active public MCP servers and over 97 million monthly SDK downloads.<\/p>\n In plain terms: an MCP server<\/strong> exposes a set of tools, an MCP client<\/strong> (Claude, ChatGPT, Cursor and others) lets the assistant call them, and the user approves the connection once. The assistant does the thinking; the server does the work.<\/p>\n Large companies are pulling ahead on agents. In McKinsey’s 2026 State of AI survey, 40% of respondents at organizations with more than $1 billion in revenue said they were scaling AI agents, up from 27% a year earlier, while the figure at smaller organizations stayed flat at 22% (McKinsey, 2026). Smaller businesses have the same assistants on their laptops; what they lack is someone to connect those assistants to their systems safely and show their team how to use them.<\/p>\n That is a classic agency job. The platform pieces already exist:<\/p>\n ChatMaxima’s MCP server lives at The assistant can list bots, read a bot’s blocks, create a new bot, add and connect blocks, update or delete a block, rename a bot and tidy the canvas. It reads each block type’s exact schema before adding it, and it can look up the client’s real connected accounts, integrations, knowledge bases, calendars, labels and spreadsheet columns instead of guessing them.<\/p>\n If two people edit the same bot at once, for example a client on Claude and your team in the dashboard, the server detects the conflict and returns the current version instead of silently overwriting either change.<\/p>\n The assistant can list and read conversations and tickets, check unread counts, assign a conversation to an agent or department, change its status, add existing labels, pause or resume the bot, and leave internal notes for the team.<\/p>\n It cannot send messages to customers<\/strong>. Replies stay with your client’s team or their bot, which is the right default for a tool driven by a general-purpose assistant.<\/p>\n MCP does not replace the dashboard. Over MCP the assistant cannot connect channels or WhatsApp numbers, publish Flows, delete whole bots, send broadcasts, manage billing or team members, or create and edit contacts. Plan your service around that: connections and launches happen in the dashboard, everyday changes and checks happen in the assistant.<\/p>\n Menus in both assistants change often, so check the current help pages when you write your client’s setup guide. The steps below were current in October 2026.<\/p>\n Custom connectors using remote MCP are available on Claude, Claude Desktop and Cowork for Free, Pro, Max, Team and Enterprise plans; Free users are limited to one custom connector. On Team plans only Owners and Primary Owners can add connectors (Claude Help Center<\/a>).<\/p>\n OpenAI’s rules are tighter. Full MCP connections, which include the tools that make changes, are available on ChatGPT Business and Enterprise\/Edu<\/strong> on the web, and only admins and owners can publish them. Pro users can connect custom MCP servers with read and fetch permissions only, and connectors are not available in the mobile apps (OpenAI Help Center<\/a>).<\/p>\n So before you sell a ChatGPT setup, check the client’s plan. A Pro account can read bots and logs but cannot make changes.<\/p>\n ChatMaxima uses a standard OAuth sign-in. The consent screen names the app that wants to connect, and if the user belongs to several ChatMaxima workspaces it lists them all with a choice of default workspace. Every workspace is ticked by default; untick any workspace the connection should not reach<\/strong>. Access can be revoked at any time under Settings, Connected Apps<\/strong>, and revocation takes effect immediately.<\/p>\n Other MCP clients work too. Cursor and the Gemini CLI connect with the same URL, and any client that supports Streamable HTTP MCP servers can be added the same way. ChatMaxima API keys are an alternative to OAuth on paid developer plans.<\/p>\n For agencies this is the important part. A single OAuth connection can cover every ChatMaxima workspace that the same login belongs to. Inside the assistant you can ask it to list your workspaces and switch between them, or name the workspace in the request (“in the Northside Fitness workspace, run the weekly bot check”).<\/p>\n Two details keep this safe:<\/p>\n For client staff, the same logic means you can give each person exactly what their role allows. A support agent connecting Claude sees inbox tools; a bot manager sees builder tools.<\/p>\n The setup takes an afternoon. The value is in the playbooks: tested prompts the client’s team can reuse, written for their bots and their workspace. Five that work well:<\/p>\n In the [client] workspace, analyze executions for the [bot name] bot over the last 7 days. List any blocks that error, branches that never run and places where people drop off. For each, suggest a fix, and do not change anything yet.<\/p>\n<\/blockquote>\n This turns execution logs into a short report a non-technical owner can act on.<\/p>\n Open the [bot name] bot. After the welcome message, add a question asking for the customer’s postcode and save it to a variable called postcode. Show me the plan first, then make the change and run a test conversation.<\/p>\n<\/blockquote>\n Asking for a plan and a test every time is the habit that keeps edits safe.<\/p>\n Draft a WhatsApp marketing template for our autumn class schedule, in English, with a “View schedule” button. Validate it against Meta’s rules and show me the final text. Only submit it after I say yes.<\/p>\n<\/blockquote>\n List open WhatsApp conversations that are unassigned. Assign any about billing to the Accounts department and add an internal note summarising the customer’s question. Do not change anything else.<\/p>\n<\/blockquote>\n Create a draft WhatsApp Flow for booking a trial class: name, phone, preferred class and preferred day. Keep it as a draft so I can review and publish it in the dashboard.<\/p>\n<\/blockquote>\n Each playbook should state the workspace, the bot, what the assistant may change, and when it must stop and ask.<\/p>\n An assistant with tools is powerful, and the risks are well documented. Prompt injection is the first item in the OWASP Top 10 for LLM applications, including indirect injection, where instructions arrive inside content the model reads (OWASP, 2025<\/a>). Claude’s own help page warns that malicious MCP servers may include hidden instructions, and OpenAI’s warns that untrusted servers increase exposure to prompt injection. The MCP specification maintains a security best practices page<\/a> covering token handling, consent and scope.<\/p>\n A practical checklist for every client:<\/p>\n Here is how a typical first engagement can run for a client with two or three bots and a small support team.<\/p>\n By the end, the client has a working setup, a written policy and a library of prompts that fit their business, which is the deliverable that justifies a setup fee.<\/p>\n Idea 25 in our business ideas list priced this at $2,500 per setup, with 4 setups a month coming to $10,000 a month<\/strong>, plus a support retainer to make the revenue recurring. That is an illustrative model, not a promise, but the structure holds:<\/p>\n Costs on your side stay low. The client’s own assistant does the reasoning, so MCP calls do not use ChatMaxima’s MaxIA credits; the client pays for their own Claude or ChatGPT plan, and the bots’ own AI usage is billed as normal.<\/p>\n If you run several clients under your own brand, see our guide to the white label AI platform model<\/a> for how agencies structure workspaces and pricing.<\/p>\n Claude MCP and ChatGPT MCP turn the assistant your client already uses into a control panel for their chatbots: weekly health checks, safe edits, template drafts and inbox triage, all in plain language. The opportunity for an agency is the part the protocol cannot do on its own: the right connections, the right access, playbooks that work and a team that knows how to use them.<\/p>\n Find the setup steps and videos on the MCP server page<\/a>, compare plans on our pricing page<\/a>, and browse the other AI agent business ideas<\/a> to see where this service fits in your offer.<\/p>\n","protected":false},"excerpt":{"rendered":" Use Claude MCP or ChatGPT MCP to let clients manage their chatbots from the AI assistant they already use.
