Skill Sets
Bundle your integration actions into curated, authenticated toolkits — and expose them to AI agents, CLIs, and any MCP-compatible client.
A permissioned API gateway over your integrations
Instead of giving an AI agent raw access to everything, define exactly which capabilities it should have.
Curated Entries
Each Skill Set contains entries linking connected apps to allowed actions. Restrict to specific actions or allow all.
Hardcoded Parameters
Lock specific parameter values. Allow "send message" but hardcode the channel to #alerts — the caller can't override it.
Component Libraries
Expose multi-step Stepper workflows as single callable tools. AI agents invoke them and poll for results.
Tokens & OAuth
Static bearer tokens for scripts, or full OAuth 2.0 with PKCE for richer client flows.
Works with every MCP client
Every Skill Set is served as a standard Model Context Protocol endpoint. Connect it to Claude, Cursor, Windsurf, or any MCP-compatible AI agent.
Dynamic parameters, dropdown options, and async polling are handled automatically through built-in meta-tools — so AI agents can progressively fill in forms and handle complex workflows.

AI Agent Tooling
Give an AI assistant scoped access to your business tools. Read from a spreadsheet, send a Slack message, create a Jira ticket — all through one authenticated Skill Set.
Internal Automation
Use static tokens with the CLI or direct HTTP calls. A deploy script can post to Slack, update a spreadsheet, and create a calendar event — all through one Skill Set.
Scoped Access for Teams
Different Skill Sets for different roles. Marketing gets email and CRM. Engineering gets project management and monitoring. Each with its own tokens and audit trail.
Workflows as Tools
Expose complex multi-step workflows as single callable tools via Component Libraries. A "Generate Report" component becomes one tool AI agents can invoke.
The stpr CLI
Discover, inspect, and execute integration actions directly from your terminal.
Full audit trail, built in
Every skill call — successful or failed — is logged with the tool name, status, authentication method, and timestamp. Call logs are retained for 30 days and visible in the Stepper UI.
- ✓ 30-day call log retention
- ✓ Track which token or OAuth client made each call
- ✓ Revoke tokens instantly from the UI
- ✓ Team-scoped access controls
Give your AI agents the tools they need
Create your first Skill Set in minutes. Define what your agents can access, generate a token, and connect via MCP.
