Overview

AI-generated overview

Remote MCP server that gives coding assistants breaking-change, deprecation and security-fix data for 38 popular APIs and SDKs, paid per call.

What you can do
  • List the tracked APIs and SDKs with the package names to query them by
  • Preview the latest breaking, deprecation and security headlines to check freshness
  • Check what changed in a package since the version your code targets, with the sentence behind each label
  • Retrieve normalized change records for one source or all of them, filtered by date and kind
  • Get a digest of everything breaking, deprecated or security-related across all sources since a given date
When to use it
Useful when an assistant writes or upgrades code against libraries it may only know from older training data, and you want to confirm breaking changes, deprecations or security fixes before committing to an approach.
Requirements
A remote streamable HTTP endpoint; no account, API key or environment variables are declared. Paid tools require x402 payment in USDC on Base, so a compatible wallet and funds are needed for upgrade_check, get_changes and digest.
Before you install
Three of the five tools cost money per call (0.01, 0.005 and 0.02 USD in USDC via x402), so repeated agent calls spend funds; set limits. Payment is handled through a crypto wallet on Base, which is a spending credential. The two free tools are read-only.

Installation

In SourceWeft

  1. Open API Change Feed in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.anthonyzilar.changefeed%2Fapi-change-feed/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
