Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "capitol-ledger": {
      "command": "uvx",
      "args": [
        "capitol-ledger-mcp"

        "CAPITOL_LEDGER_API_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add capitol-ledger --env CAPITOL_LEDGER_API_KEY=your-value --env CAPITOL_LEDGER_API_URL=your-value -- uvx capitol-ledger-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

  "mcpServers": {
    "capitol-ledger": {
      "command": "uvx",
      "args": [
        "capitol-ledger-mcp"

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "capitol-ledger": {

Common questions

Is Capitol Ledger safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CAPITOL_LEDGER_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Capitol Ledger MCP

Read-only congressional stock disclosure research for AI agents. Search official U.S. House disclosures, inspect saved synthetic disclosure-ledger portfolios, and explain portfolio changes with source and timing context.

Request pilot access · API documentation · PyPI package · Official MCP Registry · Public fictional sample · Methodology

Access

The adapter is open source. The hosted data API requires an approved Capitol Ledger API key. Request an invited free 14-day pilot at the link above. Approved pilot accounts default to 1,000 authenticated requests per UTC day, shared across keys. No payment details or automatic paid conversion. Submitting an application does not grant access or subscribe you to a newsletter.

The public JSON sample is fictional and requires no key. It is useful for inspecting the response shape; it is not a real disclosure or live data.

Install

Python 3.12 or later is required. Install the published PyPI package:

pip install capitol-ledger-mcp

Or run without a permanent installation:

uvx --from capitol-ledger-mcp capitol-ledger-mcp

To install from this public repository instead:

pip install 'git+https://github.com/joalbrecht/capitol-ledger-mcp.git'

Connect your MCP client

For an installed adapter, use this local stdio configuration:

"mcpServers": { "capitol-ledger": { "command": "capitol-ledger-mcp", "env": { "CAPITOL_LEDGER_API_URL": "https://capitol-ledger.com", "CAPITOL_LEDGER_API_KEY": "YOUR_APPROVED_API_KEY" } } } }

Replace the placeholder locally and keep the key in your client's secret store. Do not put it in a shared prompt, URL, issue, or public repository. If your client cannot find the command, use its absolute installation path.

A client using uvx can instead use "command": "uvx" and "args": ["--from", "capitol-ledger-mcp", "capitol-ledger-mcp"], with the same env. This is a local stdio server that calls a hosted HTTPS API. It is not a hosted remote MCP endpoint. No broker or trading-account credentials are needed.

Tools

Tool	Purpose	Parameters
`search_disclosures`	Search House stock disclosures with filing links and amount ranges	Optional `ticker`, `side`, `available_after`, `as_of`, `limit`, `offset`
`get_portfolio`	Opening/closing allocations for a saved synthetic ledger report	Optional `report_id`, `as_of`
`get_portfolio_changes`	Purchases, sales, and allocation changes for a saved period	Optional `report_id`, `as_of`

Example questions after connecting:

What NVDA purchases were disclosed in the last 30 days? Include source links.
Show the latest saved synthetic disclosure portfolio and its period.
What changed in that report? Use the same report ID.

Search defaults to 30 days, with at most 100 rows per call. side accepts purchase, sale, or exchange. Timestamps must include a timezone. Reuse returned as_of and available_after when paging with meta.next_offset. Pin report_id to compare a portfolio and its changes over the same period.

Coverage and interpretation

House only. Senate data is excluded.
Disclosures are delayed. The transaction date, public filing availability, and collection time are separate; do not describe a newly filed disclosure as a trade that just happened.
Disclosed amounts are ranges, not exact transaction values. Synthetic ledger values use midpoint estimates.
Portfolio snapshots represent a synthetic disclosure ledger, not actual member holdings or Capitol Ledger's executable strategy portfolio. Reports may be daily, weekly, monthly, or ad hoc; inspect returned period metadata.
Preserve source URLs, calculation metadata, freshness, and coverage warnings. Completeness is not guaranteed. Historical queries use current parsed records, not a complete versioned archive of parser/source revisions.
Research data only; no personalized investment advice or order execution.
Pilot access is for internal research workflows; contact Capitol Ledger about redistribution or serving downstream users. The code's MIT license does not grant redistribution rights to the hosted data.

Usage and errors

All three tools use the API's account-wide quota. Usage and expiry can be checked outside MCP using authenticated GET /api/v1/account (this also consumes a call).

401: invalid/revoked key.
403: inactive/expired access.
404: no completed saved report for that query.
422: invalid parameters.
429: daily quota exhausted; see the HTTP API's Retry-After header.

The tools never change subscriptions, rotate keys, submit orders, or access a local product database. API calls require HTTPS except for local development; redirects are not followed with credentials. Keys are environment credentials, not tool inputs. Model inference runs in your MCP client; this adapter only retrieves research data.

Container option

A non-root container is included for directory safety/quality checks and clients that prefer Docker. Pass credentials at runtime; they are never baked into the image.

docker build -t capitol-ledger-mcp .

docker run --rm -i -e CAPITOL_LEDGER_API_KEY -e CAPITOL_LEDGER_API_URL capitol-ledger-mcp

Use -i for MCP stdio; do not allocate a TTY. Starting the server and listing its tools do not require a key, but data calls do.

Development

pip install -e '.[dev]'

pytest ruff check .

Tests use mocked HTTP and do not need live credentials or consume API quota.

Publishing

See PUBLISHING.md for the release workflow, PyPI trusted publisher setup, and official MCP Registry metadata. Directory submissions are not evidence of endorsement or listing approval.

License and contact

MIT for the adapter code. Hosted API access and data rights are separate. Contact: hello@capitol-ledger.com.
