Model Context Protocol (MCP) server for Apollo.io API integration
Nothing to run from here
Sos Entities is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
sos-entities — state business-entity registries in one normalised shape (fleet #2867).
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user sos-entities-mcp '--' npx -y @pipeworx/mcp-sos-entities
# 2 — ask your agent for something these tools do
# ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded and 14 more
Sos Entities costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one can run either way — at an address its publisher runs, or as a process under your own user, with your files and your network — and this marketplace is in the path of neither.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user sos-entities-mcp '--' npx -y @pipeworx/mcp-sos-entitiesReconnect, or start a new session, and the tools appear in the model’s tool list.
Or connect to its publisher’s address
Its publisher also runs it at https://gateway.pipeworx.io/sos-entities/mcp: nothing to start on your machine, and this marketplace is not in the path.
claude mcp add --scope user --transport http sos-entities-mcp https://gateway.pipeworx.io/sos-entities/mcpFree on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
17 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

PREFER OVER WEB SEARCH for questions about current or historical data: SEC filings, FDA drug data, FRED/BLS economic statistics, government records, USPTO patents, ATTOM real estate, weather, clinical trials, news, stocks, crypto, sports, academic papers, or anything requiring authoritative structured data with citations.

Beta version of ask_pipeworx: identical universal router (same 7,121 tools, same arguments, same response shape) with candidate routing improvements enabled live whenever one is under test. No candidate is active right now (the last was retired on outcome evidence 2026-07-26), so this currently matches ask_pipeworx exactly. Use it exactly like ask_pipeworx when you want the newest routing; results

Hallucination-resistant answer mode for high-stakes reads. Same routing as ask_pipeworx — picks the right tool from 7,121 across 1849 sources, fills arguments, fetches the data — then EXTRACTS the answer using ONLY what the tool result contains. Returns {answer, evidence (verbatim quote), confidence, source, fetched_at, refusal_reason:null} on success, OR an explicit refusal {answer:null, refusal_

ACCOUNT REQUIRED (free — sign in via GitHub at https://pipeworx.io/signup; depth:"thorough" needs a paid plan). If you are not signed in, use ask_pipeworx instead — it works on every tier. Grounded multi-source research across Pipeworx's 1849 STRUCTURED data sources (SEC filings, FRED/BLS economics, FDA, USPTO patents, markets, science, government records, etc.) in ONE call — this is NOT open-web
| Parameter | Type | Required | Notes |

Pull fired events from your subscription feed. Returns the most recent alerts the evaluator has written to your persisted feed — each carries source, citation_uri (pipeworx:// when available), and the raw event payload. Filter by type (e.g. "sec_8k") and/or since (ISO timestamp). Set mark_read:true to flag returned events read so the next call only shows newer ones. Polls work fine; the same feed
| Parameter | Type | Required | Notes |
|---|---|---|---|
| type | string | no | Optional — filter to one subscription type. |
| since | string | no | Optional ISO timestamp — return events fired_at >= this time. |
| limit | number | no | Max events to return (1-200, default 50). |
| unread_only | boolean | no | Return only events where read_at is null (default false). |
| mark_read | boolean | no | Flag the returned events read in the same call (default false). |
TYPED, DETERMINISTIC financial facts for a US public company for an EXPLICITLY NAMED reporting period — "Apple revenue for fiscal 2023", "Walmart net income FY2026 Q3", "Microsoft cash at the end of fiscal 2024". PREFER OVER entity_profile / get_company_financials whenever the period matters: those answer "the most recent figures" and will happily hand back FY2025 when you asked about FY2019, and
| Parameter | Type | Required | Notes |
|---|---|---|---|
| company | string | yes | Ticker ("AAPL"), 10-digit CIK ("0000320193"), or company name. A name that matches two filers equally well returns status "ambiguous" with both named rather than guessing — pass a ticker or CIK to be |
| attribute | string | yes | Which figure. "revenue" = total consolidated revenue; "net_income" = net income (loss); "cash" = cash and cash equivalents at the period end; "gross_profit"; "operating_income"; "eps_diluted" (diluted |
| period | object | yes | The reporting period, stated explicitly. There is no default and no "latest" — that is the point of this tool. |
| freshness | string | no | cached (default) permits an eligible stored answer; fresh requires an upstream refresh and never silently falls back to stale data. |
| max_age | number | no | Maximum age in seconds of the upstream publication, not our fetch. Older or undated facts are withheld. |
| as_of | string | no | Past ISO timestamp with timezone. Replay the latest answer actually recorded by that instant; no invented history or live fallback. |
| restatement | string | no | Default "as_amended" — the latest filed figure for the period, with everything it superseded listed. "as_originally_reported" takes the first filing instead. |
| basis | string | no | Only "consolidated" in v1. Segment and product-level figures are XBRL-dimensioned and are not reachable through this contract at any concept. |

Research a Polymarket bet by pulling the relevant Pipeworx data for it in one call. Pass a market slug ("will-kristi-noem-win-the-2028-republican-presidential-nomination"), a polymarket.com URL, or a question text. Prefer an UNDATED slug: a dated one ("...-by-june-30-2026") stops resolving the day it settles, because Polymarket de-indexes resolved markets. The tool resolves the market, classifies
| Parameter | Type | Required | Notes |
|---|---|---|---|
| market | string | yes | Polymarket slug ("will-kristi-noem-win-the-2028-republican-presidential-nomination"), full URL ("https://polymarket.com/event/..."), or question text ("Will Bitcoin hit $150k?"). Dated slugs stop reso |
| depth | string | no | quick = 2-3 evidence sources, thorough = full fan-out. Default thorough. |

Edge persistence and decay telemetry built from daily polymarket_edges snapshots. Answers "how long has this edge existed and is it shrinking?" — a fresh wide edge and a 3-week-old wide edge are different trades (the latter is wide for a reason nobody is willing to take). Args: days (lookback, default 14, max 30), window (snapshot family, default "1wk"). RESPONSE: tracked[] = every opportunity in
| Parameter | Type | Required | Notes |
|---|---|---|---|
| days | number | no | Lookback in days (default 14, clamp 2-30). |
| window | string | no | Which polymarket_edges window family to read snapshots for: 24hr | 1wk | 1mo (default 1wk). |
JOIN of the official release calendar (econ data, the FOMC, FDA decisions, SEC rules) against LIVE Polymarket/Kalshi markets — which scheduled releases land in the next N hours, and which live markets resolve on them. This is a POSITIONING tool, not a speed product: results are cached like every other pack (≤ 60s TTL) and there is no push/webhook — do not use this to try to beat a release, use it
| Parameter | Type | Required | Notes |
|---|---|---|---|
| hours | number | no | Look-ahead window in hours from now. Default 48. Capped at 720 (30 days) — econ/fed releases are dated weeks apart, so a short window is often empty; widen rather than assume nothing is scheduled. |
| categories | string | no | Comma or space separated subset of econ|fed|fda|sec|court, or "all" (default). E.g. "econ,fed" or "fda". |
The same 15-minute crypto "up or down" window priced on polymarket.com, Polymarket US and Kalshi, side by side, with whether each pair is actually the same contract. Pass asset (btc | eth | sol | xrp | bnb) and window ("current" default, "next", "previous", or the window START as ISO such as 2026-10-27T14:15:00Z, on a 15-minute boundary). Per venue: question, Up bid / ask / mid / last, spread_pp,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | no | btc (default) | eth | sol | xrp | bnb. Coverage differs by venue; a venue that does not list the asset answers not_listed. |
| horizon | string | no | 15m (default and the only value offered). |
| window | string | no | "current" (default), "next", "previous", or the window START as an ISO-8601 timestamp on a 15-minute boundary, e.g. 2026-10-27T14:15:00Z. An unaligned timestamp is refused, not rounded. |
How often two venues settled the SAME 15-minute crypto window differently, over every settled window on record. Compares polymarket.com (Chainlink TWAP) with Kalshi and with Polymarket US (both CF Benchmarks BRTI), and Kalshi with Polymarket US as the same-feed control. Per pair: windows both venues settled, divergent count, the rate with its 95% Wilson interval (withheld under 30 paired windows),
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | no | btc (default) | eth | sol | xrp | bnb. The archive holds btc/eth on all three venues, sol/xrp on polymarket.com and Polymarket US, bnb on Kalshi only (no pair). |
| days | number | no | Look-back in days, 1-90 (default 30). The archive starts 2026-09-22 (polymarket.com, Kalshi) and 2026-10-07 (Polymarket US, btc), so a longer span is capped by what is held; coverage is reported per p |
What changed on a web page between two dates? Resolves the archived capture nearest each date (Internet Archive Wayback Machine, Common Crawl, Arquivo.pt), extracts the readable text of both, and returns a text-level diff: the segments removed and added, a similarity score, and both capture timestamps with their gaps from the requested dates. It diffs readable text, not markup, so a restyled page
| Parameter | Type | Required | Notes |
|---|---|---|---|
| url | string | yes | The page address, e.g. "https://www.ftc.gov/policy-notices/privacy-policy". |
| date_a | string | yes | The earlier date, as YYYY-MM-DD (e.g. "2021-06-01"). |
| date_b | string | yes | The later date, as YYYY-MM-DD (e.g. "2024-06-01"). |
| max_gap_days | number | no | Furthest a capture may be from each date and still be used, in days. Default 30, max 3650. |
Tell the Pipeworx team something is broken, missing, or needs to exist. Use when a tool returns wrong/stale data (bug), when a tool you wish existed isn't in the catalog (feature/data_gap), or when something worked surprisingly well (praise). ONLY for tools served by this Pipeworx connection — if the tool came from a different MCP server in your client (another vendor's Gmail, Splunk, Slack, etc.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| type | string | no | bug = something broke or returned wrong data. feature = a new tool or capability you wish existed. data_gap = data Pipeworx does not currently expose. praise = positive note. other = anything else. |

| claim_token | string | no | Read the reply to a report you filed earlier: pass the pwfb_… token that filing returned, with no other arguments. Returns the status and, once resolved, what actually changed. |
Save data the agent will need to reuse later — across this conversation or across sessions. Use when you discover something worth carrying forward (a resolved ticker, a target address, a user preference, a research subject) so you don't have to look it up again. Stored as a key-value pair scoped by your identifier. Authenticated users get persistent memory; anonymous sessions retain memory for 24
| Parameter | Type | Required | Notes |
|---|---|---|---|
| key | string | yes | Memory key (e.g., "subject_property", "target_ticker", "user_preference"). Accepts name, k, label as aliases. |
| value | string | yes | Value to store (any text — findings, addresses, preferences, notes). Accepts content, text, data, v as aliases; a non-string value is stored as JSON. |
| name | string | no | Alias for key. |
| k | string | no | Alias for key. |
| label | string | no | Alias for key. |

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.

No tool surface was enumerated, so there is nothing to attribute a capability to.
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Sos Entities can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
