Add multi-party authorization to your agent product
Integrate SignerSet into your agent harness, development platform, security solution, application, or autonomous-workflow product.
SignerSet supplies the MPAS protocol implementation and infrastructure needed to govern consequential actions inside the experience you already provide.
23 MCP servers supported today

Agent harnesses and development platforms
Make multi-party authorization part your product execution
Add SignerSet to your product’s tool-execution flow.
Your users continue working through the agent interface they already know. When an action is governed, your product creates an exact proposal, collects the signatures required by policy, and releases only the authorized request.
SignerSet can support:
- Native integration through the MPAS SDK and SignerSet's hosted APIs
- MCP-compatible integration that preserves existing tool interfaces
- Human and autonomous agent approvers
- Asynchronous workflows that wait for approvals without blocking the agent
- Cryptographic receipts your product can display, store, or export
Agent security and governance products
Add multi-party approvals to the control system you already provide
SignerSet is a composable primitive, not a replacement for existing agent security techniques.
Integrate exact-action, multi-party authorization into:
- Agent gateways
- Sandboxes and runtime-isolation platforms
- Tool permission systems
- Policy and governance products
- Identity and access-management systems
- Security monitoring and observability platforms
- Workflow and approval products
- Enterprise agent platforms
A sandbox can restrict where an agent runs while SignerSet governs the most consequential actions available inside that environment.
A policy engine can decide that an action requires two approvals while SignerSet supplies the signed evidence and deterministic verification.
An observability platform can record activity while SignerSet proves who proposed and approved the action that ultimately executed.
SignerSet provides the hosted infrastructure, integration support, and operational tooling needed to add this capability to your product, on top of the open MPAS protocol.
Application integration
Build multi-party approval into any application
If an application exposes consequential actions, it can use SignerSet to make multi-party authorization part of the application itself.
The application does not need to use a particular agent framework or interface. It could expose:
- An MCP server
- A command-line tool
- An API
- A software development kit
- A workflow engine
- A graphical user interface
- Any other surface through which an action can be proposed and executed
The application can include a SignerSet verifier directly or integrate through a proxy, bridge, or credential adapter.
Application developers can define:
- The exact actions that may require approval
- The parameters that distinguish routine from consequential operations
- The information an approver should review
- The authorization evidence the application requires before execution
- The execution result and receipt returned to the proposer
For example, an application might allow routine reads automatically and require three signatures to modify production.
Applications integrate using the open-source MPAS SDK, with SignerSet providing hosted verification infrastructure, integration support, and implementation help so teams can add multi-party authorization without building the approval infrastructure from scratch.
SignerSet also maintains a growing library of application integrations, including support for dozens of MCP servers today.
Enterprise workflow integrations
Fit multi-party authorization into enterprise workflows
Enterprises often need consequential agent actions to participate in existing business, security, and operational processes.
SignerSet can integrate into workflows that span:
- Enterprise identity and access-management systems
- Existing policy engines
- Key-management systems and hardware-backed keys
- Secret managers and credential-custody providers
- Ticketing, change-management, and approval systems
- Security monitoring and observability platforms
- Audit, evidence, and compliance systems
- Proprietary applications and internal tools
- Human and autonomous-agent review processes
An enterprise can use its existing systems to determine when approval is required while SignerSet supplies the exact-action proposal, cryptographic signatures, deterministic verification, and portable authorization evidence.
Custom integrations can vary approval requirements by application, operation, environment, account, resource, input parameters, signer group, risk classification, or other enterprise-specific conditions.
SignerSet supports managed, customer-operated, private-cloud, embedded, and hybrid deployments—including architectures in which the customer retains control of keys, credentials, policy, and data boundaries.
