Built-in capabilities (10)
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
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
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
), 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
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
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
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
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
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
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

Frequently asked questions
How do I get started with Ironclad?
Subscribe, then enter your Ironclad API token (from Company Settings → API → Access Tokens). Your AI agent connects instantly to your workspace. No code, no SDK, no webhooks — just connect and start managing contracts through conversation.
Can my AI agent launch a new contract for a counterparty?
Yes. Tell your agent to launch a contract (e.g., "start an NDA for Acme Corp") and it selects the right template, fills in counterparty details, contract value, and effective dates. The workflow enters internal review immediately — your legal team sees it in their queue within seconds.
How do I find out why a contract is stuck in approval?
Ask your agent "who still needs to approve the Acme MSA?" and it shows every approver with their status — approved, pending, or rejected — plus any comments they left. You see exactly who is blocking the contract and can follow up directly, all without opening Ironclad.
Can I manage complex contract portfolios with multiple contract types?
Absolutely. Browse all your workflow templates (NDAs, MSAs, SOWs, amendments, renewals), search across the entire executed contract repository by counterparty or keyword, and track renewal dates — perfect for legal departments, procurement teams, and enterprises managing hundreds of active agreements.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
