## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-sos-entities).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 0 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 709 tokens (~236/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `sos_search` (~243 tokens)

Search US state business-entity registries (Secretary of State) by company name — FL, NY, CO, OR, CT, PA, and TX (Comptroller franchise-tax registrations). Returns each match with entity number, legal name, entity type, status, formation date, principal address, registered agent (an agent's address only when the agent is a business), and the state source, plus data_as_of per state. Name matching is "starts with"; if nothing starts with the name it retries as "contains". Omit state to search all seven at once. Use the entity_number with sos_entity for officers. Sourced from each state's official registry publications.

Input parameters:

- `limit` (number): Max results per state (default 10, max 50).
- `name` (string, required): Company name or its beginning, e.g. "Publix Super Markets" or "Coors".
- `state` (string): Two-letter state. One of FL, NY, CO, OR, CT, TX, PA. Omit to search all.
- `status` (string): Filter by status (default any). NY, OR and PA publish active entities only.

### `sos_entity` (~181 tokens)

Full registry record for one business entity by state and entity number: legal name, type, status, formation date, principal address, registered agent, and officers/directors/managers as [{name, role}] where the state publishes them (FL up to six officers, CT principals, PA parties, NY chairman/CEO, OR authorized representative; CO and TX publish none). Individuals' addresses are never included. Get entity_number from sos_search or sos_new_entities.

Input parameters:

- `entity_number` (string, required): The state's entity number: FL document number (e.g. "L26000507120"), NY DOS ID, CO entity ID, OR registry number, CT business ALEI/account number, TX taxpayer number or SOS file number, PA filing num…
- `state` (string, required): Two-letter state: FL, NY, CO, OR, CT, TX, PA.

### `sos_new_entities` (~230 tokens)

Business entities newly formed in one state since a date — new LLCs, corporations and partnerships, newest first (formation dates from `since` through today; delayed-effective future dates are left out), with entity number, name, type, formation date, principal address and source, plus data_as_of. Optional name and entity-type filters. Deterministic order (formation date, then entity number). Florida reaches back 70 days; the other states any date. Use for new-business lead lists and formation monitoring.

Input parameters:

- `entity_type` (string): Only types containing this text, e.g. "limited liability" or "LLC" or "corporation".
- `limit` (number): Max results (default 100, max 1000).
- `name_query` (string): Only names containing this text, e.g. "dental".
- `since` (string, required): Formation date on or after, YYYY-MM-DD, e.g. "2026-10-01".
- `state` (string, required): Two-letter state: FL, NY, CO, OR, CT, TX, PA.

## Common questions

### What is the Sos Entities MCP server?

Sos Entities is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sos-entities. sos-entities, state business-entity registries in one normalised shape (fleet #2867). This page covers its npm package (@pipeworx/mcp-sos-entities).

### Is the Sos Entities MCP server safe to use?

Sos Entities 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 Sos Entities MCP server expose?

Sos Entities exposes 3 tools: sos_search, sos_entity, sos_new_entities. Their descriptions and schemas cost roughly 654 tokens of context every time the server is loaded.

### Is the Sos Entities MCP server still maintained?

Sos Entities 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 Sos Entities MCP server under?

Sos Entities 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 Sos Entities MCP server?

VerifyMCP ran 16 checks on Sos Entities, 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.
