Switchwize MCP Server

SwitchWize MCP client

Read-only MCP tools for U.S. rates, savings comparisons, financial indexes, card offers and changes, rewards, CD rollover rules, and downgrade paths.

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_MCP_URL is an optional full MCP endpoint override for developers.

Run from npm

npx -y switchwize-mcp@0.3.0

For a desktop MCP client, configure command npx with arguments ["-y", "switchwize-mcp@0.3.0"]. No API key is required.

The source bridge and package manifest now use 0.3.0, matching the published npm bridge. Building this repository does not republish the existing npm version.

The hosted server currently discovers 16 tools, three prompts, and four resources. The source-built stdio bridge forwards the hosted tool schemas and annotations, prompts, resources, structured results and tool error status.

The client connects to /api/mcp using Streamable HTTP and exposes that catalog over stdio. 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.

Validate a source checkout

npm run verify:package checks the build and package contents without publishing. npm run verify:live compares the source bridge's tools, prompts and resources with the public hosted service and performs a hypothetical Bank Gap call. It requires network access and contributes internal acceptance traffic; it does not establish independent user adoption or verify every upstream data source.

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.

Savings-gap figures are hypothetical estimates. The comparison benchmark is the average of the top three tracked savings rates, not an average across every tracked bank. Card Reality Scores model a consumer segment's assumptions and may carry stale terms; they are not personalized advice or guaranteed benefits.

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.
