What is the Definely MCP server?

Definely's MCP connector brings rules-based contract review to AI assistants: defined and undefined terms, cross-reference reports, issues lists and Vault search. That is what the definely mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

Definely's MCP connector brings rules-based contract review to AI assistants: defined and undefined terms, cross-reference reports, issues lists and Vault search.

Getting it running

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

The tools it exposes

The server publishes 8 tools. What each one is for:

  • Upload and prepare document — Send an agreement to Definely and prepare it for structural analysis — the required first step of every session
  • Defined Terms — List every capitalised or formally defined term used in the document
  • Undefined Terms — Flag terms that are used as if defined but never actually defined
  • Reference Report — Map all internal cross-references and highlight broken or circular ones
  • Ask From Document — Answer free-form questions about the uploaded agreement using its prepared structure
  • Vault Search — Search your Definely Vault document library semantically or by keyword to locate precedent
  • Issues List — Produce a full drafting issues report from comments, tracked changes and markup in the document
  • Proof Check — Review a specific clause or section for drafting errors and internal inconsistencies

What it needs from you

An active Definely licence for the full cloud suite plus valid account credentials. Claude admins may need to allow network egress to s3.amazonaws.com so document uploads can complete.

Things to watch

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Definely's toolset — Upload and prepare document, Defined Terms, Undefined Terms and 5 more — is a fair guide to whether it matches your workflow. It is maintained by Definely rather than a third party, which usually means auth handling and breaking changes are dealt with faster.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

What you can do with it

Produce a shareable issues list from a marked-up draft

Upload a negotiated draft, run the issues list, and ask for the output as a DOCX or HTML report you can send straight to a partner or counterparty.

Check consistency across a whole document suite

Point the assistant at a folder of related agreements and verify that party names, defined terms and cross-references stay consistent — work the Word add-in cannot do document by document.

Find the closest precedent in Vault

Search your firm's library for the nearest comparable agreement and have the assistant summarise where the draft in front of you departs from it.

Review a contract from your phone

Upload an attachment in the Claude mobile app, run a proof check on the indemnity clause, and reply to the requesting partner before you get off the train.

How to install the Definely MCP server

claude mcp add definely --transport http https://mcp.eu.definely.com/api/proxy/core-mcp

Configuration

An active Definely licence for the full cloud suite plus valid account credentials. Claude admins may need to allow network egress to s3.amazonaws.com so document uploads can complete.

Example prompts to try

  • Upload this NDA to Definely and list every defined term, then flag any that are used but never defined.
  • Run a full cross-reference report on this agreement and tell me if any clause references are broken.
  • Generate the issues list for this marked-up SPA and give it to me as a Word document.
  • Proof check the termination provisions and explain any inconsistencies you find.

Frequently asked questions

A language model asked to check a contract is, in effect, checking its own reasoning. Definely runs rules-based structural analysis first — which terms are defined, which cross-references resolve, where the markup raises drafting issues — and the assistant reasons on top of those deterministic results. That distinction is the entire product argument, and it matters when the output has to stand up to a risk committee.
