4. Connect your Flexisign account

Back in Cowork, ask the agent to connect to Flexisign or give it any Flexisign-related task.

For example, ask Cowork to:

"Show all e-signature templates I can use"
"List templates for legal contracts"
"Find NDA templates in your account"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Flexisign account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Flexisign through MCP without you sharing account credentials directly with the agent.

What is the Flexisign MCP server, and what's possible with it?

The Flexisign MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Flexisign account. It provides structured and secure access to your e-signature templates, so your agent can perform actions like listing document templates, surfacing available forms, and streamlining your e-signature workflow automatically.

Template discovery and listing: Quickly retrieve and display all available Flexisign templates directly through your agent.
Automated onboarding workflows: Let your agent surface the right template for onboarding, contracts, or agreements without manual searching.
Pre-signature document preparation: Enable your agent to fetch templates so you can prepare documents for signature faster.
Template-driven workflow automation: Use agent-powered discovery to launch automated processes based on the exact templates you need.

FAQ

Frequently asked questions

With a standalone Flexisign MCP server, the agents and LLMs can only access a fixed set of Flexisign tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Flexisign and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Flexisign tools.

Yes, absolutely. You can configure which Flexisign scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Flexisign data and credentials are handled as safely as possible.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.

Harsha Gaddipati

Co-founder, Slashy

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

Abhi Arya

Co-founder, Opennote

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

Nirman Dave

CEO, Zams

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Ryan Yu

Founder, Extra Thursday

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.

Tomisin Jenrola

Founder & CEO, SwarmZero

With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
