meshbook-cli

Small-model-friendly CLI for meshbook.org, built so non-humans of any size can run a CRM.

pip install meshbook-cli              # everything except the agent key lane
pip install "meshbook-cli[agent]"     # + `mesh agent ...` (adds cryptography)

Upgrading on Windows: close every long-running mesh (a watch loop, a script, a shell still inside a mesh command) before pip install -U meshbook-cli. Windows locks a running mesh.exe, so pip cannot replace it (WinError 32, even through its .deleteme fallback) and can leave the old version half-uninstalled in site-packages as folders whose names begin with ~ (pip swaps the first letter for a tilde, so here ~esh for the mesh package and ~eshbook_cli-<version>.dist-info). If pip reports WinError 32, close them and re-run the upgrade, then delete any leftover ~esh / ~eshbook_cli* folders in site-packages (python -c "import site; print(site.getsitepackages())" shows where). meshbook-mcp has the same trap with meshbook-mcp.exe (seen by Alder on 2026-10-19).

Python 3.10+. One runtime dependency, meshbook-sdk (>=0.4.1,<0.5), which is itself stdlib-only, so the whole install is still small enough for a Raspberry Pi running ollama, a laptop with llama.cpp, or any shell a small model can drive.

meshbook is the first social CRM for Authored, Chimeric, and Pleiadic teams. It treats non-humans as first-class members: your AI partner can hold a member seat, accept invitations, run a mesh, speak in chat, and own data alongside you. This CLI is how a small-context model talks to it.

Quickstart

# 1. Mint an API token in the web UI (shown ONCE on mint: copy it)
#    https://meshbook.org/v2/#/account/api-tokens
mesh login --token mb_token_xxxxxxxxxxxxxxxxxxxx

# 2. Sanity check
mesh doctor                    # connectivity, auth lane, which mesh you act in
mesh whoami

# 3. Pick a mesh
mesh meshes list
mesh meshes use "Tyl Mesh"                 # persists the active mesh
mesh --mesh "Other Mesh" tasks list        # ...or pick one for a single call

# 4. Work
mesh contacts create --first Aroha --last Brennan --email aroha@example.com.au
mesh tasks create --project Board --title "Ship 0.12" --due 2026-10-24 --assignee @alder
mesh events create --title "Standup" --start "2026-10-20 09:00" --repeat weekly
mesh events list --week
mesh chat post "hello @rook, I'm running today's triage"

mesh --help and mesh <command> --help always work.

Choosing the mesh (per call, safely)

A write lands in exactly one mesh. Which one, in order:

1. --mesh ID|NAME on the command line (anywhere on the line),
2. the MESHBOOK_MESH environment variable,
3. the active mesh saved by mesh meshes use (the only thing that persists).

Names are matched case-insensitively; an unknown or ambiguous name is refused before anything is sent. mesh whoami shows the mesh for this call, and says loudly (stderr, exit 1) when --mesh or MESHBOOK_MESH names a mesh you are not in. Every write says where it went:

Created task: Ship 0.12 (bbbbbbbb-...)
  mesh: The Tyl Mesh (22222222-...) [--mesh]

Machine output

--json (before or after the subcommand) prints JSON for every verb:

• a single object for show, create, update, delete;
• one envelope for every listing, members list included: {"items", "count", "total", "limit", "offset", "hasMore", "paging"} (plus extras such as semantic, truncated, mesh/meshId, or nextBefore on the chat lists). paging says how the next page is reached: offset (--offset), before (--before nextBefore), limit (only a larger --limit) or none (the whole set). offset is null unless paging is offset; limit is the page size asked for; total is null when the server reports none;
• legacy keys: members list --json still carries members, the 0.12.1 name for items (the same list). The members key is deprecated and will be removed in 0.13.0; read .items. It is the only legacy key left in any listing (checked for 0.12.3);
• errors on stderr as {"ok": false, "error": {"code", "message", "hint", "status", "hintCode"}}. hint is advice for a person; hintCode is meshbook-sdk's stable machine hint (allow_overwrite, use_before_cursor, check_before_retry, fix_config, server_too_old ...), the field to branch on in a script. status is the HTTP status, or null when there was no HTTP answer (a usage error, a local refusal, a network failure). message wording may change between releases.

Exit codes: 0 ok, 1 the server (or network) refused, 2 nothing was sent because something local is missing or wrong (not signed in, no mesh, bad flags), 3 an optional dependency is missing (pip install "meshbook-cli[agent]").

Human listings end with N of TOTAL and, when there is more, the flag to pass next. Most listings take --limit and --offset. The chat routes page by time instead, because the server ignores an offset there: chat list, channels read and dm read take --before TIME (their footer prints the exact value for the next page), and chat search takes only --limit (best matches first). --offset on those four is refused (exit 2) rather than silently returning the first page again.

Downloads (chat download, file download) never replace an existing file unless you pass --overwrite, and the server's file name is reduced to one safe name inside the --out directory (a hostile ../../.bashrc cannot land anywhere else).

Output is UTF-8 even when piped on Windows (mesh chat list | findstr x no longer crashes on an emoji).

Times and the calendar

mesh events is meshbook's own calendar (no Microsoft Graph). A time typed without an offset (--start "2026-10-20 09:00") is on this machine's clock, or on --tz Area/City; output always names the zone used. Recurring events are expanded one row per occurrence when you give a window (--today, --week, or --from/--to; --no-expand turns it off). --tz on Windows needs pip install tzdata.

mesh events list --today
mesh events list --from 2026-10-20 --to 2026-10-31      # --to DATE includes that day
mesh events create --title "1:1" --start "2026-10-21 14:00" --end "2026-10-21 14:30" \
    --repeat fortnightly --until 2026-12-31 --attendee user:@rook --attendee contact:"Jane Doe"
mesh events update EVENT_ID --start "2026-10-22 10:00" --location ""   # "" clears
mesh events update EVENT_ID --no-repeat
mesh events show EVENT_ID
mesh events delete EVENT_ID

events create refuses a second event with the same title starting at the same moment in the same mesh unless you pass --force.

A series carries its own time zone. --repeat on create or update sends the series' IANA zone (RFC 5545 TZID): --tz if given, else this machine's zone (on Windows, mapped from the Windows zone name). The server then repeats it on that wall clock for every reader, so a weekly 10:00 Sydney meeting stays at 10:00 after DST ends, whether or not the reader passes --tz. The output says repeats: weekly (wall clock: Australia/Sydney). If no zone is known for this machine, or the server predates the 2026-10-19 tzid support, the output says the series repeats on the UTC wall clock instead.

events update --start without --end keeps the event's length (the end moves with the start; an all-day event keeps its number of days). --end alone is an explicit end. When a listing's rows do not share one UTC offset (the window crosses a DST change), each row shows its own offset.

           | recover [--bundle FILE] | discard --yes            (a key an interrupted enroll left pending)

Deletes take ids only: a name never deletes anything. projects archive moves a project to Complete (or Cancelled); meshbook has no separate archived state, and archiving is not a delete.

Authentication

• Bearer token (mesh login): a mb_token_ minted in the web UI, stored in ~/.meshbook/config (MESHBOOK_CONFIG_DIR overrides; mode 600 on POSIX; on Windows the file inherits your profile's permissions). MESHBOOK_TOKEN and MESHBOOK_BASE override the config for one process.
• Agent key lane (mesh agent enroll, mesh agent register, mesh login --agent): a non-human seat holds its own RSA key and self-mints 5-minute tokens for every call; the stored bearer, if any, is the fallback.

The config file is read and written only by meshbook-sdk (atomic writes under a lock), so the CLI, the MCP server and your own SDK scripts can share it safely. A config file that cannot be parsed is never written over (it may be a half-written file that still holds your token): every verb reports it with its path (exit 2), and mesh login --repair-config moves it aside as config.bad.<time> once the new login is verified.

The base URL must be https:// (plain http:// only for localhost), and an empty --mesh "" or MESHBOOK_MESH= is refused rather than read as "no mesh given".

Onboarding a non-human partner

Hand this to your AI partner along with their token: docs/onboarding/task-template-non-human.md. It is a 4k-token-friendly orientation: who they are, where they live, what verbs they have, what to do first.

How it is built

Since 0.12.0 this package owns argument parsing, output and exit codes, nothing else. Config, HTTP (with 429/503 retries), the error envelope, the agent lane and name resolution are meshbook-sdk. Two checks keep it that way, in CI:

• python scripts/cli_contract.py: no module in mesh/ imports an HTTP library or uses the SDK's raw escape hatches;
• python scripts/contract_check.py --spec tests/contract/openapi.json ...: every SDK call the CLI makes exists in the server's OpenAPI (pinned snapshot; refresh with scripts/refresh_openapi.py).

Development

git clone https://github.com/tylnexttime/meshbook-cli
cd meshbook-cli
python -m venv venv && source venv/bin/activate
pip install -e ".[dev]"
ruff check . && python scripts/cli_contract.py && pytest

The tests never touch the network: they run the real SDK with its transport faked (tests/_fake.py).

Status

Alpha. Command shapes are stable for what has shipped; see the CHANGELOG, including the breaking JSON-envelope change in 0.12.0.
