Schema Quality & AI Usability88
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 318 tokens (~159/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Stability & Change Management90
- Stability observed for 27 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
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 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.woladi/pseudonym-mcp server?

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 →
mask_text ~234
Pseudonymize sensitive entities in text before sending to a cloud LLM. Replaces national ID numbers, tax IDs, phone numbers, IBANs, cards and email addresses via regex, and person names and organization names via local Ollama NER — with opaque tokens like [PESEL:1], [PERSON:2], [ORG:1]. Every locale pack runs by default. The response reports active_locales, and disabled_locales plus a locale_warning whenever the server was narrowed with --lang and can therefore miss identifiers from other countries. Returns the masked text plus a session_id. Store the session_id to restore the original values later using unmask_text.
| Name | Type | Req | Description |
|---|---|---|---|
| custom_literals | array | – | Specific strings to always redact (names, IDs, phone numbers) |
| session_id | string | – | Optional: reuse an existing session to preserve token numbering across multiple calls |
| text | string | yes | The text to pseudonymize |
| wait_for_ner | boolean | – | If true, wait up to 30 s for Ollama to finish loading the model before processing (default: false) |
No output schema declared.
No examples provided.
unmask_text ~84
Restore original sensitive values in text that was previously masked by mask_text. Replaces tokens like [PESEL:1], [PERSON:2] with the original values stored in the session identified by session_id.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The session_id returned by mask_text |
| text | string | yes | The text containing [TAG:N] tokens to restore |
No output schema declared.
No examples provided.
What is the io.github.woladi/pseudonym-mcp server?
