Smallest MCP Server
MCP server for the Smallest AI platform that enables managing AI voice agents, debugging calls, and viewing analytics directly from your IDE.
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.

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
esbuild: Missing binary integrity verification in Deno module enables remote code execution via NPM_CONFIG_REGISTRY
esbuild enables any website to send any requests to the development server and read the response
ATOMS_API_KEY"": "sk_your_key_here"Tool 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
74/74 tools missing one or more hints — activate_version (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add_agent_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add_audience_members (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +71 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
51/74 tool handlers declare input schemas (69%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 2/74 tool handlers wrap calls in try/catch (3%)
Wrap each tool handler body in try/catch and return a structured error response.
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.
Secrets stay with their owner
1 secret/sensitive value flow into network calls (ATOMS_API_KEY → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @developer-smallestai doesn't match GitHub owner smallest-inc
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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.
