APEX PSI vs Atlassian MCP Server
A side-by-side look at the APEX PSI 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.
Verdict: choose APEX PSI for cryptography work as a local process; choose Atlassian MCP Server for version control over a hosted endpoint. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose APEX PSI when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You want tools like
seal, verify, anchor.
Choose Atlassian MCP Server when
- You need dedicated capabilities in the Version Control domain.
- You prefer a remote HTTP/SSE transport.
- Its auth model fits you: other.

Tools & capabilities
APEX PSI tools 5
sealStamp a cryptographic receipt on content. Writes to the APEX PSI append-only ledger with SHA-256 hash, Ed25519 signature, and post-quantum LMS-W4-SHA256 signature. Proves existence and integrity at a point in time — not the truth of the contents.verifyConfirm a seal's integrity against the APEX PSI append-only ledger. Accepts a receipt object (from the seal tool) or a raw SHA-256 hash. Reports whether the hash is present and anchored — integrity, not the truth of the original content.anchorRead the Bitcoin (OpenTimestamps) anchoring state of the ledger's pending Merkle roots, or — only when action:'anchor' is passed explicitly — request that pending roots be aggregated and submitted to the OTS calendars. Defaults to 'status' (read-only) so a routine call never triggers a batch write. An anchor becomes confirmed only when a real Bitcoin block is found.citeGenerate a citation for a sealed receipt in APA, BibTeX, or MLA format, citing the APEX PSI ledger entry.verify_chainIndependently verify a chain of receipts against the APEX PSI ledger. Recomputes each hash's presence and integrity and reports Merkle chain continuity. Returns a verification report — a recomputation result, not an opinion or a certification.

Frequently asked questions
APEX PSI is categorized under Cryptography and uses a local stdio subprocess. Atlassian MCP Server belongs to Version Control and uses a remote HTTP/SSE transport. Pick APEX PSI 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.
APEX PSI 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 apex-psi and atlassian-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, APEX PSI has a quality signal of 60/100 (Good) with 1 views, 0 installs and 1 GitHub stars. Atlassian MCP Server has 80/100 (Excellent) with 9 views, 0 installs and 1,116 GitHub stars.
