Use the PlanProvider.Pro Form 5500 MCP
Connect an MCP-compatible agent to PlanProvider.Pro for authenticated Form 5500 plan and retirement provider research.
Connect
Add this remote MCP server in the client's MCP connections or integrations settings:
https://swhejpcukgzywbwacfdv.supabase.co/functions/v1/mcp
Complete the PlanProvider.Pro OAuth flow when the client opens it. The server address is public; OAuth and the signed-in account tier control access.
Choose the right tool
lookup_company_plan: Search indexed Form 5500 plan records by company or sponsor name. Returns the sponsor, plan name, EIN, plan number, participants, assets, and canonical plan URL.search_providers: Search auditors, advisors, administrators, insurers, and ERISA attorneys by firm name, provider type, or state.get_provider: Retrieve a provider profile by its PlanProvider.Pro URL slug.
Workflow
- Restate the company, plan, provider type, or geography being researched.
- Call the narrowest matching MCP tool.
- If
lookup_company_planreturns multiple plans, distinguish them by plan name, EIN, plan number, participants, and assets before choosing one. - Follow the canonical PlanProvider.Pro URL when the question needs fields beyond the MCP result, such as the plan's listed advisor, auditor, recordkeeper, or administrator. Request the page with
Accept: text/markdownwhen the client supports web retrieval. - Use
get_providerafter a provider slug is known and the user needs the provider's profile details. - Answer with the filing context and canonical source links.
Example
For “Who is the advisor for Dave's Produce 401(k)?”:
- Call
lookup_company_planwithcompany: "Dave's Produce". - Select the matching plan from the returned sponsor and plan details.
- Open the returned canonical plan URL and inspect its listed service providers.
- Report the advisor only if it appears on that source record, and include the plan URL.

Grounding rules
- Never invent a company, plan, provider relationship, EIN, asset value, participant count, or credential.
- Treat Form 5500 data as filing-derived research with an as-of period, not a statement of a provider relationship today.
- When no record matches, say so and ask for an alternate sponsor name, state, or EIN.
- Include canonical PlanProvider.Pro URLs in the answer.
- Distinguish MCP-returned fields from details found by following the linked PlanProvider.Pro record.
