PrismHR MCP

If you run a PEO on PrismHR and want Claude to hit your tenant directly, this is the plumbing. It handles auth, session keepalive, pagination, and PrismHR's quirks (silent 401s, batch caps, 500-as-empty-set responses) so you don't rewrite that logic in every script. The core exposes 447 verified REST methods across payroll, benefits, billing, and compliance domains, plus a scope-gated consent system to prevent accidental production writes. Ships with Microsoft 365 connectors for W-2 distribution and carrier EDI workflows. The OSS tier gives you read access and meta tools; paid tiers add pre-built assistants for ACA audits, 941 reconciliation, and 834 enrollment file generation. Built by Simploy for brokers and payroll teams replacing Postman collections with agentic workflows.
