How to Use the Common Paper MCP in Claude Code

Q: How do I audit active webhooks using Claude Code?

You ask Claude Code to list your endpoints, and it runs listwebhooks to output them to your terminal. You can then instruct it to run deletewebhook on any obsolete Common Paper URLs.

Q: Can I check if a specific client signed their contract in Claude Code?

Yes, Claude Code calls searchagreementsbyemail via the MCP interface to check the status of contracts sent to that address. It prints the exact Common Paper signature state directly to your standard output.

Q: How do I fetch template details in a headless environment?

Claude Code uses gettemplate to retrieve the JSON schema of any Common Paper contract template. You can pipe this data directly into local configuration files or database seeders.

Manage your Common Paper contracts, templates, and webhooks directly from your terminal with Claude Code.

Perplexity

Pipe contract lists directly into terminal utilities

The `list_agreements` tool lets Claude Code fetch your entire contract log via this MCP Server and pipe the output directly into grep or jq. You can filter active Common Paper negotiations, extract recipient emails, and format the results without leaving your shell. For targeted searches, Claude Code runs `search_agreements_by_email` to isolate agreements for a specific client. This terminal-first approach keeps your command-line workflow fast and keyboard-driven.

Script agreement dispatches via the MCP Server

The `send_agreement` tool enables Claude Code to trigger contract dispatches directly from shell scripts or cron jobs. You can pass Common Paper template IDs and recipient details as arguments, allowing your terminal agent to handle automated legal workflows. Before sending, Claude Code uses `get_template` to verify that the template structure matches your script's payload requirements. This prevents runtime errors and failed Common Paper contract dispatches in headless environments.

Manage production webhooks from your command line

The `create_webhook` tool allows Claude Code to register new event listeners directly during your CI/CD deployment phase using this MCP toolset. You can script the setup of production endpoints so your application is ready to receive Common Paper signature events immediately. To keep your environment clean, Claude Code uses `list_webhooks` and `delete_webhook` to audit and prune stale testing endpoints. This ensures only active production servers receive Common Paper contract event notifications.
