Sendbyte-Africa/sendbyte-mcp
Enables AI agents to send emails and manage sending domains, templates, analytics, and content checks through the SendByte platform using the Model Context Protocol.
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.
send_emailSend a transactional email through SendByte. The sender domain must be a verified sending domain (or use the shared test domain with a test key). Provide html and/or text, or a template_id with variables. A test key (sk_test_) sandboxes the send.
get_emailFetch one email by id, including its delivery status and event timeline (queued, sent, delivered, bounced, complained).
list_emailsList recent emails for the project, newest first, with cursor pagination. Optionally filter by delivery status.
list_domainsList the sending domains on the account with their verification status and whether deliverability (SPF/DMARC/MAIL FROM) is fully configured.
get_domainGet one sending domain by id, including the DNS records to publish (DKIM, SPF, DMARC, MAIL FROM) and their current state.
verify_domainRe-check a domain's DNS records and SES status now, and report which records pass and whether the domain is verified.
list_templatesList saved email templates for the project (id, name, subject, format, version).
get_templateGet one saved template by id, including its subject and body (html/text/mjml).
preview_templateRender a saved template with sample variables and return the resolved subject and body, without sending anything.
get_analyticsGet daily send counts by status and deliverability rates (delivered, bounce, complaint) over the last N days.
scan_contentPre-send deliverability and spam-risk check for email content. Returns a score, risk level, and the specific signals found, so an agent can fix risky content before sending.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
Vitest allows Remote Code Execution when accessing a malicious website while Vitest API server is listening
@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
SENDBYTE_API_KEYNo global install is needed. Point your MCP client at npx @sendbyte/mcp and set in its environment.SENDBYTE_BASE_URLno Override the API host for self-hosted, staging, or local development. Defaults to https://api.sendbyte.africa.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
11/11 tools missing one or more hints — send_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_emails (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.
Tool inputs are validated
9/11 tool handlers declare input schemas (82%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.19.0 (high), @modelcontextprotocol/sdk@1.19.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.

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.
