docs/API.md gains the endpoint and what it returns, why `play` is the bigger
and lesser of the two, the element-by-id route found while probing, and the
per-library shapes with the traps in them — the string "true", the inline cloze
markers, the correct-option-first convention, and the UI subtrees that drown an
exercise in button labels.
CLAUDE.md's "no quiz of its own" note said a contentId was the only handle onto
the content. That was the reason nobody looked further, so it now says where to
look instead.

docs/API.md gains the findings: the endpoint and its required version
parameter, the one-time code and the two error codes worth naming, the Z that
means local time, a substitution being two periods, the unused exam module
that puts announced tests in the period notes, and a day without lessons that
is not a holiday. Those cost an afternoon of probing to learn and nothing
upstream states them.
docs/AUTH.md sets the key against the Schulcloud token it sits beside: no
password, nothing to keep alive, revocable on its own, and not read-only in
itself — which is why the allowlist exists. PI.md and DEPLOYMENT.md add the
four values, the container recreate a changed key needs, and the clock
requirement; the Pi's troubleshooting table gains both failure messages.
README and CLAUDE.md say what the server now is: Schulcloud for the material,
WebUntis for the day. Smoke is 89 checks with the index and a key, 87
live-only, 9 fewer without one.

claude.ai's connector dialog does offer request headers, on its second step,
after the URL has been probed, so the connector no longer needs the secret
path. MCP_AUTH_TOKEN already worked there as a bearer or X-Api-Key, but it
also opens /api, which can replace the Schulcloud token and stream the file
mirror, and claude.ai stores the header's value.
MCP_CONNECTOR_TOKEN is a second token, accepted on /mcp only and refused on
/api, and rotated without touching Claude Code or the CLI. The config refuses
one shorter than 32 characters, equal to MCP_AUTH_TOKEN, or set without it,
and never echoes a value. Every accepted token is compared in full, so the
timing does not tell which one matched.
The gate also takes a bare Authorization value, because claude.ai sends a
header exactly as typed and its docs warn that most servers reject a token
entered without "Bearer ". It takes X-Auth-Token too, the other name its
dialog offers.
The docs now set up the header; the secret path stays as a fallback for
clients that cannot send one. 184 tests. Smoke 79/79 and 77/77 on the local
instance.

claude.ai's connector dialog takes a name and a URL. Sending a bearer token
needs a "Request headers" beta most accounts lack, and OAuth is not built
yet, so with MCP_PATH_SECRET set the endpoint is also served at
/<secret>/mcp without the bearer token — a trial until OAuth replaces it.
The path is the credential there. It is compared in constant time, and a
wrong one answers 404 like any unknown path. The config refuses fewer than 32
URL-safe characters and never echoes the value, nothing in the server logs
request paths, and the Caddy snippet rewrites the segment before an access
log entry is written (verified against Caddy 2.11). Claude Code and the CLI
keep the bearer token; DEPLOYMENT.md says what the path trades away.
178 tests. Smoke 76/76 and 74/74 on the local instance.

A token lasts 30 days and only a browser login yields one — the account is
federated, so the server cannot mint it. Replacing it meant editing .env and
recreating the container, every month.
`schulcloud token set` (a hidden prompt, or piped input) and a /token page
both send it to PUT /api/token. The server checks it with Schulcloud first —
well-formed, unexpired, still logged in, the same account — then swaps it
into the config every request reads, restarts the keepalive and saves it in
STATE_DIR, a new volume, with mode 0600. At startup the newer of the saved
token and TSC_JWT_COOKIE wins, unless they belong to different accounts. A
refused paste changes nothing, and the token is never logged.
The keepalive's pings carry a generation, so a 401 for the old token that
arrives after a swap cannot stop the new cycle. `schulcloud token`, whoami
and the log report the expiry and warn a week ahead.
Found on the way: a host that is off for more than two hours loses the
session however long the token has left — this machine lost it overnight —
which is what the always-on Pi is for.
174 tests. Smoke 72/72 on the local instance, and a real swap verified end to
end there.

A course or room can now be attached to a message rather than fetched:
schulcloud://courses/<id> and schulcloud://rooms/<id> carry exactly what
get_course and get_room return. Deliberately coarse — a picker lists every
resource at once, which suits some twenty courses and not a thousand files.
Two prompts, in German because the school is: zusammenfassung summarises a
course or room, and pruefungsvorbereitung prepares for an exam with practice
questions and a study plan. Each embeds the overview and says where material
hides and what cannot be read.
Claude Code shaped the details, read from its bundle rather than its docs.
It splits prompt arguments on whitespace and drops extra words, so words
arrive joined with "_", and courses match by fragments, whole words first,
so LF1 is not ambiguous with LF10. Its @ autocomplete shows a resource's
description, so the description carries the name. Errors are ProtocolError,
because McpError's message prefix is doubled by the client.
Verified in interactive Claude Code: @-mention, autocomplete and the prompt
commands. 157 tests. Smoke 67/67 live; 69/69 and 67/67 on the local instance.

Many teachers never use topics or boards; their material sits in the
course's file area, and the tools answered "0 files" for courses holding
dozens of worksheets — 21 of 26 courses on the live account. Persönliche,
Kurs-, Team- and Geteilte Dateien live in the legacy file store, not in
files-storage, and its service is not in the public ingress. The only way in
is the legacy client: HTML listings, and GET /files/signedurl for a
pre-signed download.
core/legacy-files.ts turns that into one path tree — /my, /courses/<course>,
/teams/<team>, /shared — resolving names that contain "/", ids anywhere in a
path, and wrong or ambiguous names with a message saying what is there. A
listing that does not parse throws; it never reads as an empty folder.
Some of the legacy client's GET routes write (GET /files/share/ mints a
share token), so getFileManagerPage allows only the listing routes, by
pattern. Signed URLs are fetched with no credentials and must be https.
- MCP: fs_list, fs_tree, fs_find and fs_read; get_course lists course files.
- CLI: schulcloud fs ls, tree, find and get, recursive and resumable.
- API: /api/fs/list, tree, find and file.
- Index: the crawl walks the file manager (INDEX_FILE_MANAGER, on by
default), so search covers the text inside those files and sync mirrors
them under <course>/Kurs-Dateien.
The local instance gains a fixture for all four areas. It needed a loopback,
so signed URLs open from the host, and a pre-created bucket, since MinIO
does not implement PutBucketCors.
135 tests. Smoke 55/55 live; 57/57 and 55/55 on the local instance.

With .env pointing at the real account, testing against the local instance
became dangerous: process env beats --env-file, so a local smoke run would
crawl fixtures straight into the live index, where a per-course refresh
carries them forward indefinitely. mcp-env.sh now pins its own database
(schulcloud_local) and mirror as well as the instance.
The override publishes the server on MCP_HOST_PORT and takes
CRAWL_INTERVAL_MS from .env, since what_changed can only report what
happened between crawls. The build context leaves out tmp/, which holds a
mirror of the account's files, and local-instance/.
probe checks live what the gap fixes established locally: the /api/v1 course
and user routes, classes, room allowedOperations as an object, and the
preview enums on a real file. A failure there means a feature degrades
rather than breaks.

Claude Code's default MCP scope is `local`, which is per-project: the
server is stored under that directory in ~/.claude.json and does not
appear in `claude mcp list` from anywhere else. docs/LOCAL.md showed the
default and so produced exactly that confusion.
User scope is right here — the point is to ask about coursework from any
directory. Project scope would write a .mcp.json into the repo, which is
wrong when the HTTP config carries a bearer token.
Also adds the symptom and the fix, since "it is not in the list" has one
overwhelmingly likely cause.

Adds docker-compose.override.yml (local-only: publishes the server on
127.0.0.1:8080 and Postgres on 127.0.0.1:55432, crawls on demand) and
docs/LOCAL.md covering the stack, Claude Code registration over both
transports, the CLI, and the test suites.
Two bugs that only running the real container could find:
The mirror volume was root-owned while the container runs as node, so
every file write failed with EACCES. Docker initialises a named volume
from the image directory including its ownership, so the fix is to
create /data/mirror owned by node in the image. This was easy to miss
because the indexer records a per-file failure rather than crashing —
the crawl "succeeded" with 4 skipped. Earlier direct-node testing missed
it entirely by writing to a scratch dir owned by the developer.
The store tests TRUNCATE, and pointing TEST_DATABASE_URL at the dev
database put their fixtures into real data. They now refuse any database
whose name does not contain "test".
Verified against the rebuilt container: 4 files mirrored, image-only PDF
detection firing in the real pipeline, both transports showing
✔ Connected in `claude mcp list`, and a whoami tool call driven end to
end through `claude -p`.
