Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
get_message Read a message ~88
Fully parse one message by its id (from search_messages): headers, decoded text body (truncated if huge), and attachment names/types/sizes. Attachment contents are never returned.
| Name | Type | Req | Description |
|---|---|---|---|
| id | integer | yes | Message id from search results |
| path | string | yes | Path to an .mbox file (e.g. a Google Takeout export) or a directory of .eml files |
No output schema declared.
No examples provided.
open_archive Open a local email archive ~90
Index an .mbox file (Google Takeout, Thunderbird) or a directory of .eml files — entirely locally, nothing leaves the machine. Returns message count, date range, and top senders. Large archives are indexed once and cached.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Path to an .mbox file (e.g. a Google Takeout export) or a directory of .eml files |
No output schema declared.
No examples provided.
search_messages Search the archive ~193
Search indexed envelopes (from/to/subject/date). `query` matches sender and subject. `body_query` additionally full-parses candidate messages to search body text — it is capped, so narrow with sender/date filters first; the result reports how many candidates were scanned.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Only messages on/after this date, YYYY-MM-DD |
| before | string | – | Only messages on/before this date, YYYY-MM-DD |
| body_query | string | – | Substring searched in message bodies (bounded scan) |
| from | string | – | Substring of the sender |
| limit | integer | – | Max results |
| path | string | yes | Path to an .mbox file (e.g. a Google Takeout export) or a directory of .eml files |
| query | string | – | Keyword matched against sender and subject |
| subject | string | – | Substring of the subject |
No output schema declared.
No examples provided.
