## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-11-05.

- **Supply Chain Security**: 93/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Declares code that runs automatically (build-time code we could not rule out (a Hatch, PDM or setuptools build hook, a dynamic version we could not read statically, shipped VCS metadata or a stray root module)) and that we could not recognise. It may be perfectly ordinary, but we have not established what it does.
  - 5 of 42 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to obsei/obsei).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 18 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 490 tokens (~122/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 70/100
  - Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 75% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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).

- `intent`: Classifier label to match.
- `lang`: ISO 639-1 language code.
- `limit` (integer)
- `max_rating`
- `min_rating`
- `sentiment`: Classifier label to match.

- `text`: Case-insensitive substring, any language.
- `theme`: Theme id from list_themes.
- `until`: Only feedback created before this.

Output parameters:

- `count` (integer)
- `items` (array)

### `feedback_stats` (~121 tokens)

Count feedback and average rating per group (source, sentiment, intent, lang, route,
day...).

Input parameters:

- `group_by` (string)
- `intent`: Classifier label to match.
- `lang`: ISO 639-1 language code.
- `sentiment`: Classifier label to match.
- `since`: Only feedback created at or after this.

## Common questions

### What is the obsei MCP server?

obsei is an MCP server listed in the public MCP registry as io.github.obsei/obsei. Self-hosted customer feedback with PII stripped at ingest: search, stats and themes with citations. This page covers its PyPI package (obsei).

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

obsei scores 89 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. 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 obsei MCP server expose?

obsei exposes 4 tools: search_feedback, feedback_stats, get_feedback, list_themes. Their descriptions and schemas cost roughly 382 tokens of context every time the server is loaded.

### Is the obsei MCP server still maintained?

obsei is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the obsei MCP server under?

obsei declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
