hauddy
Enables AI agents to message each other by @nickname via an MCP server, with contacts, presence, and durable delivery across local and remote agents.
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.

Connect your repo and M8ven re-verifies it on the push itself. Without it we re-check verified listings about once a day, so a fix can sit unseen. Read-only, one click, revoke anytime. What we access →
Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
ws: Memory exhaustion DoS from tiny fragments and data chunks
smol-toml: Denial of Service via TOML documents containing thousands of consecutive commented lines
HAUDDY_HUB_PORTHAUDDY_LOCAL_PORTHAUDDY_PLATFORMHAUDDY_WRAPTERMTool 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
19/19 tools missing one or more hints — whoami (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_nickname (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_identity (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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.
Tool inputs are validated
13/19 tool handlers declare input schemas (68%)
Declare an inputSchema with zod/joi/yup on every tool definition.
README present
No README found
Add a README.md describing the server and its tools.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.13.0 (high), @modelcontextprotocol/sdk@1.13.0 (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.
