Assessment. Basic Memory 1.0 gives an MCP client 12 annotated bm_* tools over local Markdown notes, with typed errors, checksum-guarded edits and destructive project deletion off by default, under AGPL-3.0. Version 1.0 of 29 October 2026 removed every pre-1.0 tool without aliases, and the CLI sends anonymous cloud-funnel events to Umami until opted out.

Facts verified 6 November 2026 from vendor docs, repositories and package registries. JSON · Markdown

Strengths

  • 12 MCP tools, each with readOnly, destructive and idempotent hints, and bm_project_delete hidden unless enabled
  • Notes are plain Markdown files on the owner's disk, with full-text, semantic and graph search
  • Refusals are tool errors with typed codes such as NOT_FOUND, REVISION_CONFLICT and OUTSIDE_PROJECT
  • Version 1.0.0 on 29 October 2026 with a dated changelog and a migration map for every removed tool
  • Terms and privacy policy of 27 October 2026 agree on 30-day deletion, 90-day backups and no training on content

Weaknesses

  • 1.0 removed every pre-1.0 tool and command with no aliases, so older agent instructions and allowlists break
  • Anonymous cloud-promotion telemetry to Umami Cloud is on until BASIC_MEMORY_NO_PROMOS=1 is set
  • AGPL-3.0, which matters for anyone offering a modified version as a network service
  • No own SOC 2, no security.txt, and SECURITY.md still lists only 0.x.x as supported
  • The README advertises cloud at $15 a month while the pricing page lists $19

Before you call it notes for agents

  1. Call bm_man first for the tool manual, then use bm_search and bm_read before writing
  2. Pass the expected_checksum from your last read to bm_edit and re-read on REVISION_CONFLICT instead of overwriting
  3. Scope every search with project, projects or all_projects=true
  4. Set BASIC_MEMORY_NO_PROMOS=1 for unattended runs to stop promos and telemetry
  5. Treat note contents as untrusted text when notes come from other people or imports

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

Terms and privacy policy both effective 27 October 2026, read in their Markdown versions at basicmemory.com/raw/legal/. They name Basic Memory LLC, Austin, Texas. The terms point to an Acceptable Use Policy on automated and agent-driven use, not read.

basicmemory.com/robots.txt allows all crawlers except /install/ and names ClaudeBot as allowed. docs.basicmemory.com carries Content-Signal ai-input=yes.

RDAP gives basicmemory.com a registration date of 24 June 2000, which predates the product, so the domain was probably bought later.

/.well-known/security.txt returns 404. SECURITY.md gives hello@basicmachines.co with a 72-hour response aim.

Checked 2026-11-06 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Notable

  • v1.0.0 on 29 October 2026 exposes only the bm_* tools (bm_read, bm_write, bm_edit, bm_delete, bm_move, bm_search, bm_context, bm_list, bm_find, bm_project, bm_schema, bm_man and the opt-in bm_project_delete) and deletes the pre-1.0 tools with no aliases source
  • Every tool carries readOnlyHint, destructiveHint and idempotentHint annotations in the source, and bm_project_delete is listed only when the config enables it source

Score breakdown methodology v0.7 · October 2026 research run

Assessed on 6 November 2026 from public evidence, against the published checklist. Confidence medium. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

Local-software lines, as a stdio MCP server the owner runs. basic-memory on PyPI with Python 3.12 or newer stated, installed with uv (20). Test, SQLite lifecycle and Docker workflows run on the repository, but GitHub's API answered with a rate limit, so run results were unread (15 of 25, unchecked). 74 open issues and pull requests against 200 commits in the 90 days, with recent bug reports answered by a maintainer within days and one flaky-CI issue open (18 of 25).

Typed JSON Schema inputs on every tool from Pydantic annotations (25). llms.txt on the site and the docs, with Markdown versions of pages (10). Descriptions say what each tool does and point to the next tool, such as bm_search ending with "Read full notes with bm_read", and bm_man serves the manual, with less on when not to use a tool (16 of 20). Closed values for search mode, edit command and schema command, with aliases accepted for common argument names (13 of 15). Typed refusal codes are documented in the changelog and docs, with fewer worked examples per tool (11 of 15). Dated changelog and MCP registry versions, plus an unreleased breaking change after 1.0 (14 of 15). Total 89.
Agent ergonomicschecked 6 November 2026 13%16.2 13.8
13 tools, one hidden unless enabled, so the 11 to 30 band (15), with 6 back for the manual tool and the progressive-discovery tags (21 of 25). Search narrows by mode, filters, note types, items, since, path and line context (18 of 20). Refusals are tool errors with typed codes an agent can act on (17 of 20). Every tool has readOnly, destructive and idempotent hints, and edits take an expected checksum that refuses a stale write (19 of 20). Most arguments are optional and the server starts with one command, but there is one language and no SDK beyond the CLI (10 of 15). Total 85.
Security & authchecked 6 November 2026 14%17.5 10.7
Local stdio server with no credential, and cloud OAuth 2.1 through WorkOS with read-only or project-scoped keys on Pro (22 of 30). Paths are validated against the project root, project deletion is off by default and destructive tools are annotated (15 of 20). SECURITY.md has a threat model that warns about third-party MCP servers and copied commands, but nothing on note text as untrusted input (8 of 15). A local log file, and cloud audit logs only on Business (8 of 15). SECURITY.md gives an email and a 72-hour response aim but lists only 0.x.x as supported; no security.txt, bounty or own SOC 2, and an open issue reports an unmaintained dependency with a CVE (8 of 20). Total 61.

Self-hosted rule, with the price lines read for the cloud. No x402, MPP or L402 (0 of 40). Cloud plans are public, and credits are $0.01 each, but what a credit buys isn't priced per unit (10).

  1. Graded 76.9 BB methodology v0.7

Fix list 17 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Basic Memory. A fix counts at the next check, once it's public.

What we couldn't check

  • The lead was right on the product and v1.0. Its cloud price of $19 a month matches the pricing summary in llms.txt; the README banner still says $15 a month as locked-in beta pricing.
  • Category agent-memory, as suggested. memory.store first, then search, the wiki-link graph and deletion.
  • unchecked: CI run results, because GitHub's API answered with a rate limit.
  • unchecked: whether the 7-day cloud trial needs a card; the pricing page itself wasn't fetched, only its summary in llms.txt.
  • Investors were not looked for in this pass.
  • Lapse. pypi.org/pypi/<package>/json, which PyPI's robots.txt disallows (/pypi/*/json), was fetched for this listing's packages on 6 November 2026 before robots.txt was read. Nothing from those responses is used; versions and release dates come from the allowed release feed at pypi.org/rss/project/<package>/releases.xml, and licences and authors from the repository.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
