drawio-mcp-server
Enables AI agents to create, modify, and analyze diagrams using Draw.io (Diagrams.net) through MCP commands.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get-selected-nodes获取鼠标选中的节点信息，如果不是用户主动要求，大模型禁止调用该接口
add-node可以在当前页面添加节点. It accepts multiple optional input parameter.
edit-params-assign-node-conf编辑赋值节点配置信息
edit-switchto-node-conf编辑条件节点配置信息
edit-calculate-node-conf编辑多元计算节点配置信息
add-edgeThis tool creates an edge, sometimes called also a relation, between two vertexes (cells).
delete-node-by-idDeletes a node,
delete-edge-by-idDeletes a edge,
get-nodes-categories查询节点列表
get-graph-data查询页面上的规则流程图信息
get-flow-params获取当前规则的参数信息
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
hono: CORS Middleware reflects any Origin with credentials when `origin` defaults to the wildcard
LOGGER_TYPETool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
11/11 tools missing one or more hints — get-selected-nodes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add-node (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); edit-params-assign-node-conf (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/11 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 7 high severity in production deps — @hono/node-server@1.19.7 (high), @modelcontextprotocol/sdk@1.25.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
