Ironclad MCP Tools for LangChain (10)
These 10 tools become available when you connect Ironclad to LangChain via MCP:
ironclad_get_approvals
Returns each approver with their status (approved/pending/rejected), approval date, and any comments. Essential for tracking where a contract is stuck in the approval process. Use when the user asks "who still needs to approve this contract?" or "why is this contract delayed?" Get the approval status of a specific Ironclad contract workflow — who approved, who is pending, and who rejected
ironclad_get_comments
Returns each comment with author, timestamp, and message. Comments capture internal review discussions, legal feedback, and negotiation notes. Use to review the discussion history of a contract or understand decision context. Get all comments and discussion on an Ironclad contract workflow — internal team communication and negotiation notes
ironclad_get_record
Use for contract lookups, renewal planning, or compliance reviews. Get complete details of an executed Ironclad contract record — all metadata, dates, obligations, and linked documents
ironclad_get_workflow
), current workflow step, assigned reviewers and approvers, counterparty name, related document links, and complete timeline of actions. Use to drill into a specific contract for status updates or details. Get full details of a specific Ironclad contract workflow — current step, all attributes, counterparty info, and timeline
ironclad_launch_workflow
Attributes is a JSON object containing the contract-specific fields defined in the template (e.g., counterparty name, contract value, effective date, jurisdiction). The workflow immediately enters the first step (typically internal review or drafting). Launch a new Ironclad contract workflow from a template — start the process for an NDA, MSA, SOW, or any configured contract type
ironclad_list_records
Returns contract name, counterparty, contract type, key dates (effective, expiration, renewal), total value, and status. Records are the final, executed versions of contracts. Use when the user asks about existing agreements, upcoming renewals, or the contract repository. List executed contract records in Ironclad — fully signed agreements stored in the contract repository with key metadata
ironclad_list_templates
Each template defines: the contract type (NDA, MSA, SOW, amendments, etc.), required attributes/fields, approval chain, and signature requirements. Template IDs are needed to launch new workflows via ironclad_launch_workflow. Use when the user asks "what contract types can we create?" or needs a template ID. List available Ironclad workflow templates — NDA, MSA, SOW, and other pre-configured contract types ready to launch
ironclad_list_webhooks
Webhooks are used to notify external systems when events occur in Ironclad (e.g., workflow launched, contract signed). Returns webhook ID, name, target URL, and events. Use when auditing integrations or checking connectivity. List all configured webhooks in Ironclad — monitor external notifications for workflow events
ironclad_list_workflows
Each workflow represents a contract moving through its lifecycle: drafting → internal review → approval → counterparty negotiation → signature → execution. Returns workflow name, current step/status, creator, counterparty, template used, and dates. Use when the user asks about contracts in progress, pending approvals, or the contract pipeline. List Ironclad contract workflows in progress — NDAs, MSAs, SOWs, and other agreements moving through approval and signature stages
ironclad_search_records
Matches contract names, counterparty names, descriptions, and attribute values. Use when the user asks "find our contract with Acme", "show all NDAs", or needs to locate a specific agreement by keyword. Search Ironclad contract records by keyword — find specific agreements, counterparties, or contract types across the repository
Example Prompts for Ironclad in LangChain
Ready-to-use prompts you can give your LangChain agent to start working with Ironclad immediately.
"Show me all contracts pending approval this week"
"Launch an NDA for Acme Corp."
"Search for all active MSAs renewing next month."
