Why it exists

Your AI has the context. Document generation MCP builds the rest.

Three things that slow every deal down, and what changes once Proposal.biz is connected.

  • Before

    You explain the same context twice

    Your AI already read the brief and the email thread, but you still retype it all into Proposal.biz.

    With MCP

    Your AI turns the transcript, notes or thread straight into a document.

  • Before

    Documents break your flow.

    You stop what you're doing, open another app and start a fresh draft before anything goes out.

    With MCP

    One prompt, one branded draft, and a link back right where you're already working.

  • Before

    Every tool needs its own setup

    Connecting each AI to each app means starting from scratch every time.

    With MCP

    One open standard, one key, every AI assistant you use.

How it works

MCP is the bridge. Proposal.biz does the building.

Your AI assistant doesn't write the document. It passes your request to Proposal.biz, which builds it from your own approved content.

  1. 1 · You

    Prompt your AI

    In Claude, ChatGPT, Gemini or any MCP tool, with whatever context you have.

  2. 2 · MCP

    Request is passed on

    Your key connects the assistant directly to your Proposal.biz account.

  3. 3 · Proposal.biz

    Document is built

    Using your account's:

    • Brand and tone
    • Content library
    • Pricing

  4. 4 · Back in chat

    You get a link

    The finished draft sits in your account, ready to open, edit or send.

One link, always current

Keep refining in chat. The link never changes.

Follow-up prompts update the same draft instead of creating a new one. No duplicates, no version hunting, and one link that always opens the latest.

  1. 1“Draft an SOW for Northwind”
  2. 2“Add the Acme case study”
  3. 3“Switch to the Pro pricing tier”

Your connection details

Every tool asks for the same three things.

Server URL
https://app.proposal.biz/api/mcp
Transport
Streamable HTTP
Key
Your API key from Settings → API Keys

Create a key in Settings, then paste the server URL and key into your AI tool's connector settings. No code is needed. That's it.

Setup

Connected in three steps

No code and no config files for most tools. Developers can add the same URL and key to any MCP config.

  1. Create your key

    Go to Settings → API Keys and click Create Key. Copy it right away: it's only shown once.

  2. Add it to your AI tool

    Paste the server URL and your key into your AI tool's connector or MCP settings.

    app.proposal.biz/api/mcp

  3. Start prompting

    Describe the document you need, or point it at your content library. You'll get a link to the finished draft.

Ownership and control

Your AI drafts. You stay in control.

Your AI writes the first draft. You still decide exactly what reaches your client, and when.

Your key, your account

Documents are created only in the account the key belongs to.

Revoke any time

Delete a key in Settings → API Keys and that connection stops immediately.

Review before sending

Every document lands as a draft. Sending and signing happen in Proposal.biz.

It's a document generation MCP that lets Claude, ChatGPT, Gemini and other MCP-compatible assistants request documents from your Proposal.biz account. You prompt your AI, MCP passes the request on, and Proposal.biz builds the document and sends back a link.
Any document type your Proposal.biz account supports: proposals, quotes, SOWs, contracts, pitch decks, one-pagers. Just say which one you need in the prompt.
It helps. Proposal.biz MCP pulls pricing, tone, and messaging from your content library, so if you haven't added your content yet, your AI has less to work with and you'll end up filling in more by hand.
No. The key is tied to your Proposal.biz account, not to Claude, ChatGPT, or Gemini specifically. Add the same key to a different AI tool and it works the same way.
Yes. Nothing stops you from adding the same key to Claude and ChatGPT at once, each one prompts Proposal.biz independently.
Yes. It lands in the same Proposal.biz account and folder structure your team already works from, organized exactly like anything built in the dashboard.
That depends on the AI tool, not on Proposal.biz. Some assistants offer MCP support on their free tier, others limit it to paid plans. Check your AI tool's own settings to see what your plan allows.
Nothing. The document lives in your Proposal.biz account, not inside the AI tool, so switching or losing access to that AI tool does not touch it.
Copy-pasting only moves text around, you still have to open Proposal.biz to turn it into an actual document. MCP lets your AI create that document directly in your account and hand you back a link, instead of you copying anything in yourself.
