## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 822 tokens (~164/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (5)

### `get_latest` (~133 tokens)

Latest readings

Current headline readings (value, unit, observation date) for the site's charts: S&P 500 level, Shiller CAPE, forward P/E for the S&P 500, Nasdaq 100, SOX and sector ETFs, VIX, drawdown from the high, breadth, Magnificent 7 weight and more. Pass `id` for one chart, or omit it for all.

Input parameters:

- `id` (string): Chart id, e.g. "pe" (Shiller CAPE), "forward-pe", "ndx-forward-pe", "drawdown", "vix". Omit for every reading.

### `annual_returns` (~124 tokens)

Calendar-year returns

Calendar-year returns by year, price return and total return (dividends reinvested), with the arithmetic mean and compound annual rate over the complete years in the range. Indexes: sp500 (from 1928), ndx, sox, xlk, xlf, xly, xlp. The current year is year-to-date and flagged `ytd`.

Input parameters:

- `from_year` (integer): First year to include.
- `index` (string): Which index or ETF. Default sp500.
- `to_year` (integer): Last year to include.

### `index_changes` (~98 tokens)

Index additions and deletions

Constituent changes with effective date, the company added, the company removed and the reason. sp500 from 2016, ndx from 2020. Newest first.

Input parameters:

- `index` (string): Default sp500.
- `limit` (integer): Default 20.
- `since` (string): Only changes effective on or after this date (YYYY-MM-DD).
- `ticker` (string): Only changes that add or remove this ticker.

### `search_charts` (~95 tokens)

Find a chart or dataset

Search the site's charts by topic or question (e.g. "bear markets", "Shiller CAPE", "Nasdaq 100 drawdown", "monthly seasonality"). Returns each chart's title, the question it answers, its page and the dataset path to pass to get_dataset.

Input parameters:

- `limit` (integer): Default 10.
- `query` (string, required): Words to match against chart titles and the questions they answer.

### `get_dataset` (~224 tokens)

Read a dataset

Read one published dataset (the JSON behind a chart), e.g. "sp500/drawdowns", "sp500/pe", "ndx/forward-pe", "recessions". Rows can be filtered by `since`/`until` on their `date` (or `year`). A result is capped at about 60,000 characters: when a file is larger (long daily series), each array keeps its most recent rows and the cut is reported under `windowed`. Scalars and summary fields are always included.

Input parameters:

- `path` (string, required): Dataset path without /api/ and .json, as returned by search_charts.
- `since` (string): Keep rows dated on or after this (YYYY-MM-DD or YYYY).
- `tail` (integer): Rows kept per array after filtering, from the end. By default every row is returned when the result fits; long daily series are cut to their most recent rows and reported under `windowed`.
- `until` (string): Keep rows dated on or before this (YYYY-MM-DD or YYYY).

## Common questions

### What is the History of Market MCP server?

History of Market is an MCP server listed in the public MCP registry as com.historyofmarket/market-history. Read-only U.S. stock market history: S&P 500 since 1928, CAPE, drawdowns, index changes. This page covers its hosted endpoint (https://historyofmarket.com/mcp).

### Is the History of Market MCP server safe to use?

History of Market scores 77 out of 100 on VerifyMCP. 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 History of Market MCP server expose?

History of Market exposes 5 tools: get_latest, annual_returns, index_changes, search_charts, get_dataset. Their descriptions and schemas cost roughly 674 tokens of context every time the server is loaded.

### Does the History of Market MCP server require authentication?

No. We connected to History of Market without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the History of Market MCP server still maintained?

History of Market 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 did VerifyMCP test on the History of Market MCP server?

VerifyMCP ran 13 checks on History of Market, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
