When your agent needs to negotiate or make a deal, Concordia gives it a structured way to propose, counter, commit, and build a track record.
Concordia Protocol MCP server exists for a simple reason — assistants are far more useful when they can act on Concordia Protocol directly instead of describing what you should do. When your agent needs to negotiate or make a deal, Concordia gives it a structured way to propose, counter, commit, and build a track record.
Once Concordia Protocol is connected, these are the calls the assistant has available:
Multi — attribute offer optimizationFeedback — open an issue or start a discussionInstallation goes through your MCP client rather than a global install: point it at @sanctuary-framework/mcp-server on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Concordia Protocol's toolset — Multi, Feedback — is a fair guide to whether it matches your workflow. It is maintained by eriknewton; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
