Category Communication
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability83
- 99% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1914 tokens (~23/item across 83 items; 2 tools + 81 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management80
- Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (50% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
read_doc Read a Sendora document ~157
Read one of Sendora's documents whole, as Markdown: a guide (sendora://docs/…), an API operation (sendora://reference/…), the error codes (sendora://errors) or an SDK's README and rules for agents (sendora://sdk/readme and sendora://sdk/skill for TypeScript, sendora://sdk/python/readme and sendora://sdk/python/skill for Python, sendora://sdk/php/readme and sendora://sdk/php/skill for PHP, and sendora://sdk/laravel/readme for Laravel). sendora://index lists every document; search_docs finds the right one.
| Name | Type | Req | Description |
|---|---|---|---|
| uri | string | yes | A document's address, such as sendora://index. |
No output schema declared.
No examples provided.
search_docs Search the Sendora docs ~114
Search Sendora's guides, API reference, error codes and the SDKs' READMEs. Use it before writing code against either SDK or the HTTP API, and whenever an error code or a limit needs explaining. Answers the best-matching sections with their document's uri; read the whole document with read_doc.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many sections, at most. |
| query | string | yes | Words to look for, such as "verify webhook signature" or an error code such as recipient_suppressed. |
| Name | Type | Req | Description |
|---|---|---|---|
| results | array | yes | The best-matching sections, the best first. |

How do I install the Sendora MCP server?
Sendora is a hosted endpoint at https://mcp.sendora.se/docs, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Sendora MCP server?
Sendora is an MCP server listed in the public MCP registry as se.sendora/mcp. Sendora's docs and API for coding agents: send test mail, read the log, set up webhooks. This page covers its hosted endpoint (https://mcp.sendora.se/docs).
Is the Sendora MCP server safe to use?
Sendora scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Sendora MCP server expose?
Sendora exposes 2 tools: search_docs, read_doc. Their descriptions and schemas cost roughly 271 tokens of context every time the server is loaded.
Does the Sendora MCP server require authentication?
No. We connected to Sendora without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Sendora MCP server still maintained?
