First-party Prismatic.io skills for building code-native integrations and custom connectors — spin up connectors without clicking through the UI.

Prismatic publishes these skills for their integration platform. They teach Claude Code how to build code-native Prismatic integrations: scaffolding connectors, writing action handlers, testing locally with their SDK, and deploying. Official source, focused scope.

Use Cases

Real-world ways to use prismatic-skills

Build a custom Prismatic connector for an internal API

👤 Integration engineers on teams using Prismatic ⏱ ~90 min advanced

When to use: You have an internal API that your Prismatic flows need to talk to.

Flow

Scaffold the connector

Use prismatic-skills. Scaffold a connector for our Orders API — base URL, bearer auth, actions for list, get, create.✓ Copied

→ Connector directory with TS entry points, manifest, test files
Implement actions

Fill in the listOrders action with pagination and error handling.✓ Copied

→ TS implementation with types and Prismatic input/output conventions
Test locally

Run the test harness with a mock response.✓ Copied

→ prism tests output; green

Outcome: A deployable connector with actions your flows can use.

Pitfalls

Missing input validation — Prismatic validates at the platform boundary; still use Zod or similar for runtime safety

Combine with: filesystem

Add a new action to an existing Prismatic connector

👤 Maintainers of deployed connectors ⏱ ~30 min intermediate

When to use: Business needs a new action (e.g., refund flow) on an existing integration.

Flow

Identify the pattern

Use prismatic-skills. Look at the existing actions/ and mimic the pattern for a new 'refundOrder' action.✓ Copied

→ Action file consistent with existing style
Publish

Bump the connector version and deploy.✓ Copied

→ prism integrations:publish succeeded

Outcome: Connector updated without breaking existing flows.

Pitfalls

Breaking input schema without version bump — Version the connector; old flows pin to old version until migrated

Combinations

Pair with other MCPs for X10 leverage

prismatic-skill + filesystem

Manage a multi-connector monorepo

Add connectors/widgets-api/ following the same pattern as connectors/users-api/.✓ Copied

prismatic-skill + github

Review connector PRs with skill context

Review this PR against Prismatic connector conventions.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
scaffold_connector	name, auth type, actions	New connector	0
write_action	action spec	Per-action implementation	0
run_tests	connector path	Before publish	local
publish_connector	connector path	Deploy	Prismatic deploy

Cost & Limits

What this costs to run

API quota: None in skill
Tokens per call: Moderate
Monetary: Prismatic plan applies; skill is free
Tip: Test locally with the SDK before pushing to reduce deploy churn.

Security

Permissions, secrets, blast radius

Credential storage: Prismatic credentials via prism CLI (not stored in skill)

Data egress: Prismatic platform + whatever APIs your connectors talk to

Connector code runs on the Prismatic platform — don't embed secrets; use Prismatic's credential store.

Troubleshooting

Common errors and fixes

prism login fails

Token scope or expiry; re-login via browser flow

Verify: prism me

Connector publishes but flows can't see new action

Customers may need to upgrade connector version in their flow settings

Input schema rejected

Prismatic enforces specific input shapes; consult their docs or the skill's action templates
