Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
Zyberno stock valuation 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.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.

Free on mcprush, and it answers at its publisher’s own address: 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 pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Runs a two-stage discounted cash flow on numbers you provide and returns the fair value per share, the margin of safety against the price you gave, and how much of the value sits in the terminal stage. Cash flow grows at your growth rate for the stage-one years, then forever at your terminal rate, with the terminal value from the Gordon Growth Model discounted back over the stage-one years. Use w

| current_stock_price | number | yes | Current share price, used only to compute the margin of safety against the fair value. |

Returns Zyberno's stored valuation record for a single US-listed company: Margin of Safety against a discounted cash flow estimate, the Brina Gap (the growth rate the business can fund from its own returns minus the growth rate its current price implies), the Brina Matrix quadrant those two produce together, the Zyberno quality score, and trailing twelve month fundamentals from SEC filings. Use w

| symbol | string | yes | Ticker symbol of a US-listed company, for example AAPL, MSFT, or BRK.B. Case insensitive. Non-US listings and most OTC ADRs are not covered and return no data. |
Returns the Zyberno Market Valuation Score, a single 0 to 100 reading of how expensive the US equity market is relative to its own history, combining the Buffett Indicator, the Shiller PE, the 10 year minus 2 year Treasury curve and the Baa credit spread. Use for questions about the market as a whole, overall valuation levels, or whether US stocks broadly look expensive or cheap right now. Do not

Returns the two lists Zyberno publishes each month from one fixed screen. The first holds companies where the Margin of Safety and the Brina Gap both read as undervalued, labelled Double Discount. The second holds companies that look cheap on trailing earnings power while the Brina Gap reads negative, labelled value trap. Takes no parameters: the thresholds, sector exclusions and ranking are fixed

Searches Zyberno's database of roughly 10,000 US-listed companies and returns those matching the numeric criteria you supply, ranked by a field you choose. All metrics are computed from SEC filings. Use when the user wants to find, filter, rank, or count companies by their characteristics rather than asking about one company by name.

Runs a Monte Carlo simulation over a portfolio balance and returns the distribution of possible end values: percentiles, mean, median, and if you give a goal amount, the share of simulated paths that reached it. Returns are drawn from a normal distribution using the expected return and volatility you supply. Use when the user asks about the range or probability of outcomes rather than a single pr

| expected_annual_return_pct | number | yes | Expected average annual return in percent. Pass 7 for 7 percent. |
| annual_volatility_pct | number | yes | Annual standard deviation of returns in percent. Pass 15 for 15 percent. Broad equity indices have historically run in the mid teens. |
| monthly_contribution | number | no | Amount added every month. Defaults to 0. |
| goal_amount | number | no | Optional target end value. When set, the result reports the share of simulated paths that finished at or above it. |
| inflation_rate_pct | number | no | Annual inflation in percent. When set above 0, results are expressed in today's purchasing power. Defaults to 0. |
| fee_rate_pct | number | no | Annual fee drag in percent, for example a fund expense ratio. Defaults to 0. |
| simulations | integer | no | Number of simulated paths. Defaults to 10000. More paths stabilise the tails and cost more time. |

Release 2.0.0 · scanned 20 Oct 2026
Graded from the tools this server lists, not from its source code.
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.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

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.
