SwitchWize MCP client

Read-only MCP tools for U.S. deposit and mortgage rate observations, savings comparisons, index datasets, and credit-card Reality Scores.

Connect now

For clients supporting Streamable HTTP, use the hosted endpoint:

https://www.switchwize.com/api/mcp

No SwitchWize account or API key is required. The API is rate-limited. Documentation: SwitchWize Developers.

Run the stdio client from source

Use a supported Node.js LTS release and npm:

git clone https://github.com/switchwize/switchwize-mcp.git
cd switchwize-mcp
npm ci --ignore-scripts
npm run build
npm start

For a desktop MCP client, configure command node with the absolute path to dist/index.js as its argument. No environment file or database credentials are needed. SWITCHWIZE_API_URL is an optional API-origin override for developers.

Run from npm

npx -y switchwize-mcp@0.1.0

For a desktop MCP client, configure command npx with arguments ["-y", "switchwize-mcp@0.1.0"]. No API key is required.

Available tools

• get_top_rates
• get_top_hysa_rates
• get_bank_gap
• compare_switch_savings
• get_rate_freshness
• get_index_dataset
• get_bank_gap_index

The client discovers the tool list from /api/public/tools and forwards calls to /api/public/tools/{tool}. It does not initiate financial transactions or request bank credentials. Balance inputs supplied to tools are transmitted to the hosted API; do not include account numbers or other sensitive identifiers.

Data boundaries

Observations may be aggregator-sourced and may be aging. Preserve each response's source dates and freshness labels. Monthly index data is not a current offer. Confirm product terms directly with the provider before making a decision.

Attribute data as SwitchWize (switchwize.com). The MIT license covers this client software, not upstream datasets, third-party materials, or trademarks. See data and service terms.

Package verification

npm run verify:package builds the client and checks the npm tarball against an exact allowlist: LICENSE, README.md, dist/index.js, and package.json. npm pack creates a local tarball; neither command publishes it.
