Check Credential Handling in mcp-use Before Connecting Real Accounts
You will confirm the package source and test credential handling with a throwaway token before connecting real services. This reduces risk of token exposure, since the directory entry flags credential exposure as a key risk.
- Confirm official sourceCheck the npm page for the CLI package name
- Read the project docsFind where the framework expects credentials
- Test with narrow tokenUse a throwaway, read-only token
- Check logs and filesLook for the test token value
- Revoke test tokenConfirm the old credential no longer works
Why it matters
The mcp-use directory entry lists credential exposure as a key risk: MCP servers handle authentication tokens and API keys, and misconfiguration can leak them to AI models or logs. The entry does not explain how this framework stores or logs tokens, so check that yourself before you connect a real account. Project details are on mcp-use on GitHub (opens external site).
Steps
-
Find the official install instructions for the CLI on its npm package page, and confirm the package name matches what you plan to install. Copy the name from that page rather than typing it from memory.
-
Install with the command shown on the directory entry, but only after step 1 confirms the source.
npx -y mcp-use
-
Read the project's documentation on how credentials are supplied. The directory entry does not say, so do not assume an environment variable, config file, or flag. List every place you plan to put a token.
-
Create a throwaway token with the narrowest scope the service offers, such as read-only, and use it for the first test connection.
-
After the test, search the logs and any generated files for the throwaway token's value. If it appears in a file, delete that file or exclude it from version control before you commit anything.
-
Revoke the throwaway token and confirm the connection fails with it. Only then move to a real account, and rotate any token that may have been exposed.
Common mistakes
- Assuming the directory risk notes describe how this framework handles tokens. They describe MCP servers in general.
- Pasting a production token into a quick test and forgetting to rotate it afterward.
- Skipping the log and file check after a test run.
- Installing a package by name without first checking the official instructions.
