AnchorRegistry vs Server Everything

A side-by-side look at the AnchorRegistry and Server Everything MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Verdict: choose AnchorRegistry for cryptography work over a hosted endpoint; choose Server Everything for other tools and integrations as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

AnchorRegistry tools 3

  • ar_verify_aridResolve an AnchorRegistry AR-ID to its full provenance record. Use this when you encounter an SPDX-Anchor or DAPX-Anchor tag (e.g. in a README, paper, model card, or website) and need to confirm what the artifact is, who anchored it, when, what type it is, and whether the tree has been sealed, retracted, voided, or affirmed. Free, public, no auth required.
  • ar_verify_by_hashResolve an artifact by its SHA-256 manifest hash. Use this when you have the artifact itself but no AR-ID, and want to check whether it has been anchored. Returns the AR-ID and full provenance record if found, or a clear "not anchored" response otherwise.
  • ar_resolve_treeResolve the full provenance tree for an AR-ID. Returns every anchor in the tree (root + all descendants) with their relationships, types, manifest hashes, and timestamps. Use this when you need to understand a multi-artifact provenance chain — for example, a research paper anchored as the root with its training dataset and model weights as children.

Frequently asked questions

AnchorRegistry is categorized under Cryptography and uses a remote HTTP/SSE transport. Server Everything belongs to Other Tools and Integrations and uses a local stdio subprocess. Pick AnchorRegistry for cryptography work and Server Everything for other tools and integrations.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

AnchorRegistry has no declared pricing — check the project's own site. Server Everything is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add anchorregistry and modelcontextprotocol-server-everything as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, AnchorRegistry has a quality signal of 47/100 (Fair) with 1 views, 0 installs and 0 GitHub stars. Server Everything has 55/100 (Good) with 9 views, 0 installs and 91,405 GitHub stars.
