At a Glance & Executive Verdict

Endiagram MCP

Architecture & Design · Local stdio

Quality: 55/100 (Good) | Auth: No auth required

Posecode

Architecture & Design · Local stdio

Quality: 55/100 (Good) | Auth: No auth required

Verdict Summary: Choose Endiagram MCP if you need specialized Architecture & Design tools running via a local process. Choose Posecode if your workspace requires Architecture & Design integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.

Category & Scope

Tools & Capabilities Breakdown

Endiagram MCP Tools (7)

structure

detect_findings=true` flags risks (unguarded-sink, single-cut-path, multi-cut-path); `node=X` returns per-node centrality (betweenness, closeness, eigenvector).

invariant

rules` (one per line) checks custom claims. Four supported shapes: `no bridge that is also hub` · `every path from X to Y passes through at least one of [A,B,C]` (precedence) · `no node with centrality above N` · `removing any single node disconnects at most N others`.

live

—

reachable

defense_nodes=a,b,c` checks whether guards cover every path.

equivalent

Compare mode (`source_a`+`source_b`): edit distance + spectral cospectrality. Evolve mode (`source`+`patch`): plain EN adds; `- name` removes; same-name replaces.
