## MCP tools (4)

### `pbgc_plan_status` (~222 tokens)

Look up a named pension plan sponsor's PBGC status: whether a pension plan was terminated and taken over by PBGC ("trusteed") because it was underfunded, or is still an active plan currently paying PBGC premiums (single-employer or multiemployer). Searches both PBGC registers by sponsor name, plan name, and/or employer EIN, and returns data_as_of so the caller knows how current each match is. Answers "did United Airlines' pension plan get taken over by PBGC", "is Acme Corp's pension plan still active", "what happened to the Enron pension plan". Example: pbgc_plan_status({ sponsor: "US Airways" }). Keyless.

Input parameters:

- `ein` (string): Employer EIN (9 digits, dashes optional)
- `limit` (number): Max matches per register (default 10, max 50)
- `plan_name` (string): Pension plan name (partial match ok)
- `sponsor` (string): Plan sponsor / employer name, e.g. "US Airways"

### `pbgc_search_trusteed_plans` (~256 tokens)

Search PBGC's register of single-employer pension plans PBGC has trusteed — i.e. taken over as trustee because the plan terminated underfunded. Returns case number, sponsor, plan name, EIN, termination date, date PBGC became trustee, and participant count at termination. Answers "pension plans PBGC has taken over in Illinois", "list trusteed plans for United Airlines", "biggest PBGC trusteeships by participants". Example: pbgc_search_trusteed_plans({ sponsor: "United Airlines" }); pbgc_search_trusteed_plans({ state: "IL", limit: 25 }). Keyless.

Input parameters:

- `ein` (string): Employer EIN (9 digits, dashes optional)
- `limit` (number): Max results (default 20, max 100)
- `plan_name` (string): Pension plan name (fuzzy, partial ok)
- `sort` (string): "trusteeship_date desc" (default), "trusteeship_date asc", or "participants desc"
- `sponsor` (string): Plan sponsor name (fuzzy, partial ok)
- `state` (string): Two-letter US state code of the sponsor

### `pbgc_search_premium_filers` (~250 tokens)

Search plans currently paying PBGC premiums — active pension plans (NOT terminated/trusteed), single-employer or multiemployer. Returns plan name, sponsor, admin city/state, EIN, plan effective date, and participant count. Answers "pension plans sponsored by Delta Air Lines", "multiemployer plans paying PBGC premiums in New York", "how many participants in the Acme Corp pension plan". Example: pbgc_search_premium_filers({ sponsor: "Delta Air Lines" }); pbgc_search_premium_filers({ state: "NY", plan_type: "multiemployer", limit: 25 }). Keyless.

Input parameters:

- `ein` (string): Employer EIN (9 digits, dashes optional)
- `limit` (number): Max results (default 20, max 100)
- `plan_name` (string): Pension plan name (fuzzy, partial ok)
- `plan_type` (string): "single-employer" or "multiemployer" — omit for both
- `sponsor` (string): Plan sponsor name (fuzzy, partial ok)
- `state` (string): Two-letter US state code of the plan administrator

### `pbgc_industry_totals` (~139 tokens)

Aggregate counts across PBGC's registers: how many pension plans PBGC has trusteed (and total participants affected), and how many plans are currently paying premiums (single-employer vs multiemployer), optionally restricted to one US state. Answers "how many pension plans has PBGC taken over", "how many multiemployer plans pay PBGC premiums", "PBGC trusteeships in Texas". Example: pbgc_industry_totals({}); pbgc_industry_totals({ state: "TX" }). Keyless.

Input parameters:

- `state` (string): Restrict to one US state, e.g. "TX"

## Common questions

### What is the Pbgc MCP server?

Pbgc is an MCP server listed in the public MCP registry as io.github.pipeworx-io/pbgc. PBGC MCP, pension plan terminations and premium filings. This page covers its npm package (@pipeworx/mcp-pbgc).

### Is the Pbgc MCP server safe to use?

Pbgc scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Pbgc MCP server expose?

Pbgc exposes 4 tools: pbgc_plan_status, pbgc_search_trusteed_plans, pbgc_search_premium_filers, pbgc_industry_totals. Their descriptions and schemas cost roughly 867 tokens of context every time the server is loaded.

### Is the Pbgc MCP server still maintained?

Pbgc is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Pbgc MCP server under?

Pbgc declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Pbgc MCP server?

VerifyMCP ran 16 checks on Pbgc, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
