## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 81/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 309 tokens (~154/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the Sessionplan MCP server?

## MCP tools (2)

### `create_session_link` (~115 tokens)

Create Sessionplan

Use this when the user wants a new Sessionplan for a workshop, training, meeting, event, or other timed session, or a revised link after decoding an existing Sessionplan. Pass a complete session object matching inputSchema; partial updates and patches are not accepted. The returned structuredContent.link is an opaque snapshot URL and must be presented verbatim.

Input parameters:

- `session` (object, required): Canonical format for newly generated Sessionplan documents. Include all required fields and only documented properties. Use declared category/person IDs and the supported item hierarchy.

Output parameters:

- `link` (string): Opaque, directly openable Sessionplan snapshot URL. Present this exact value verbatim; do not reconstruct, normalize, shorten, decode, or modify it.
- `summary` (object): Optional compact summary of the encoded session.

### `decode_session_link` (~103 tokens)

Open Sessionplan

Use this whenever the user provides a Sessionplan URL, URL hash, or v2 snapshot code and wants it read, summarized, reviewed, validated, or changed. The validated structuredContent.session is the source of truth. For changes, modify the complete decoded session and pass it to create_session_link; the existing snapshot is not modified in place.

Input parameters:

- `link` (string, required): Unmodified Sessionplan URL, URL hash, or v2 snapshot code supplied by the user.

Output parameters:

- `session` (object)

## Common questions

### What is the Sessionplan MCP server?

Sessionplan is an MCP server listed in the public MCP registry as de.sessionplan/sessionplan. Create and edit visual agendas for workshops, trainings, meetings, and events. This page covers its hosted endpoint (https://sessionplan.de/mcp/).

### Is the Sessionplan MCP server safe to use?

Sessionplan scores 89 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 Sessionplan MCP server expose?

Sessionplan exposes 2 tools: create_session_link, decode_session_link. Their descriptions and schemas cost roughly 218 tokens of context every time the server is loaded.

### Does the Sessionplan MCP server require authentication?

No. We connected to Sessionplan without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Sessionplan MCP server still maintained?

Sessionplan is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
