Why Use Vercel AI SDK with the HotDocs MCP Server
Vercel AI SDK provides unique advantages when paired with HotDocs through the Model Context Protocol.
TypeScript-first: every MCP tool gets full type inference, IDE autocomplete, and compile-time error checking out of the box
Framework-agnostic core works with Next.js, Nuxt, SvelteKit, or any Node.js runtime. same HotDocs integration everywhere
Built-in streaming UI primitives let you display HotDocs tool results progressively in React, Svelte, or Vue components
Edge-compatible: the AI SDK runs on Vercel Edge Functions, Cloudflare Workers, and other edge runtimes for minimal latency
HotDocs + Vercel AI SDK Use Cases
Practical scenarios where Vercel AI SDK combined with the HotDocs MCP Server delivers measurable value.
AI-powered web apps: build dashboards that query HotDocs in real-time and stream results to the UI with zero loading states
API backends: create serverless endpoints that orchestrate HotDocs tools and return structured JSON responses to any frontend
Chatbots with tool use: embed HotDocs capabilities into conversational interfaces with streaming responses and tool call visibility
Internal tools: build admin panels where team members interact with HotDocs through natural language queries
HotDocs MCP Tools for Vercel AI SDK (14)
These 14 tools become available when you connect HotDocs to Vercel AI SDK via MCP:
complete_assembly
This processes all collected answers and assembles the final documents based on the template configuration. After calling this, the assembled documents become available for download via list_documents and get_document_content. You must have already created a work item, created a version/session, and provided answers (via interview or update_answers). The workItemId and versionId must match an existing work item and its version. Complete document assembly for a work item version
create_interview_session
This endpoint prepares the system to collect answers for the template variables. The response contains interview data needed to render the HotDocs interview UI. Use this before displaying the interview to the user or before assembling documents. The versionId should be unique for each interview session (e.g., v1, v2, or a UUID). Create a new interview session for a work item
create_work_item
A work item is associated with a specific template package and holds answers provided during interviews. You must provide a unique workItemId (alphanumeric identifier you choose) and optionally a templatePackageId. The workItemId becomes the reference for all subsequent operations (interview, assembly, download). IMPORTANT: workItemId must be unique and URL-safe (letters, numbers, hyphens only). Create a new work item in HotDocs Advance
get_auth_token
This is primarily a utility function for debugging authentication issues. The token is used internally by all other tools automatically. If other tools fail with auth errors, verify your credentials are correct. Get a fresh HotDocs API access token
get_document_content
Use this to download the final generated document (PDF, Word, etc.) after assembly is complete. You need the workItemId and the documentId (obtained from list_documents). The response includes the document content and a download URL for direct access. Download/get content of an assembled document
get_template_package
Use the template package ID obtained from list_template_packages. This helps understand the template structure before creating work items. Get details of a specific template package
get_unanswered_variables
This shows which template variables were not provided answers during the interview process. Useful for validating interview completeness before or after document assembly. Requires the workItemId and documentId (from list_documents). The response includes the list of unanswered variables and assembly results. Get unanswered variables from an assembled document
get_work_item
Use this to inspect a work item before or after conducting interviews or assembling documents. The workItemId is the unique identifier you assigned when creating the work item. Get details of a specific work item
list_documents
After completing assembly, this shows all generated documents with their IDs, names, and metadata. Use the document IDs returned here to download individual documents via get_document_content. Each document entry includes filename, creation date, and assembly results information. List all assembled documents for a work item
list_template_packages
Template packages define the structure of documents that can be assembled. Each package contains interview questions and document output configurations. Use this to discover what templates are available for document assembly. The response includes package IDs which are required for creating work items. List all available template packages in HotDocs Advance
list_template_versions
Each template can have multiple versions over time. This shows version history and helps identify which version is currently live/active. Use the package_id from list_template_packages to query versions. List all versions of a template package
list_work_items
You can filter by user ID and/or date range to find specific work items. Leave all parameters empty to list all work items. This is useful for auditing, tracking progress, or finding existing work items to continue working on. Date format should be ISO 8601 (e.g., 2024-01-15 or 2024-01-15T10:30:00). List work items with optional filters
list_work_items_by_date
This is optimized for date-based filtering and auditing. Both fromDate and toDate are required for this tool. Use ISO 8601 date format (e.g., 2024-01-01 or 2024-01-01T00:00:00 for datetime). This is useful for generating reports on document assembly activity over time periods. List work items filtered by a specific date range
update_answers
The answer_xml parameter must contain valid HotDocs answer XML format that matches the template variables. This is useful for automated/batch document assembly where you already have the data. You can call this multiple times to incrementally add answers. Answer XML format example: <AnswerSet><A v="VariableName"><V>Answer Value</V></A></AnswerSet> Update answers for a work item using XML answer format
Example Prompts for HotDocs in Vercel AI SDK
Ready-to-use prompts you can give your Vercel AI SDK agent to start working with HotDocs immediately.
"List all available template packages in my HotDocs tenancy."
"Create a new work item 'contract-2024-001' using the employment contract template and assemble a document with these details: employee name is John Smith, position is Software Engineer, start date is March 1st 2024, salary is $95,000."
"Show me all work items created in the last 30 days and check if there are any unanswered variables in the documents."
