AnchorRegistry vs Atlassian MCP Server

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

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. Atlassian MCP Server belongs to Version Control and uses a remote HTTP/SSE transport. Pick AnchorRegistry for cryptography work and Atlassian MCP Server for version control.

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. Atlassian MCP Server is listed as free. Auth: other. 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 atlassian-mcp-server 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. Atlassian MCP Server has 80/100 (Excellent) with 9 views, 0 installs and 1,120 GitHub stars.
