Claude Code: ask. ### `blame` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Per-line blame of a postgres file at any commit (code-history index): the commit that wrote each line, as `git blame` with git's default diff. ignore_revs (default true) passes through the pgindent/reformat commits of .git-blame-ignore-revs when they replaced lines one-for-one; reverse adds the commit that removed each line later on the version's branch. At most 2000 lines per call; commits lists author, date and subject per short sha. Not the same as git_blame, which returns a file's commit history. ``` ### `commit_buildfarm_status` - The name "commit_buildfarm_status" says "commit": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Buildfarm results for one PostgreSQL commit: every animal that built it, with branch, status (passed/failed/flapping), the failing stage and the log url, plus a {passed, failed, flapping, unknown} rollup. commit_sha is a SHA (>= 7 hex) or a branch, tag or major version (17, 9.6) for the commit it points at.

The diff itself is not included (git_diff, or git_show_file for one file). Cite the sha and the thread's https://postgr.es/m/. ``` ### `cross_reference` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text What relates to one stored item. ref: a Message-ID or message URL, a commit SHA, repo@sha or commit URL, a docs URL or page.html, a wiki URL or title, a commitfest URL, or CVE-YYYY-NNNNN. Returns the related mail threads, commits, docs pages, wiki pages, commitfest entries and people, each listing why, strongest first: explicit links (Discussion: trailers, messages citing the SHA, commitfest thread links, pages linking the URL, commits to a docs page's SGML), shared identifiers (BUG #N, CVE ids, code identifiers), then similar topic by embeddings. kinds narrows; limit_per_kind (default 5, max 25); version picks the docs release. ~3 s budget: late kinds go in timed_out with partial=true.

Searches every mailing list (inbox narrows it) with hybrid keyword + semantic ranking and returns cited passages that fit token_budget (default 4000, max 32000): one passage per thread, each the author's own words (quotes, signature and patch removed, cut at ~1200 chars) with url, inbox, message_id, from and date. found=false with a reason when the archive does not appear to discuss the question, instead of weak matches. Retrieval only: write the answer yourself. Cite each claim with its passage url or https://postgr.es/m/; open a thread with get_thread. ``` ### `whats_new` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Catch up: everything a person or group did, and where they were named, in a window, newest first per kind (mail grouped by thread). who: a name (fuzzy; close matches return ambiguous [{name, hash}]), email, hash:<8 hex>, team:, org:, new:, a phrase ('the core team'), or a list. since/until: ISO date, today, 2w/14d/1m, pg19 (a release's development window), all; default 14 days. during: a calendar event uid/url. topic narrows by hybrid search.

A literal by default; match=regex for a PostgreSQL regex (^ and $ are per line; \b \< \> as in grep), match=identifier for any of snake_case/CamelCase/UPPER spellings. File sets agree with `git grep -l` at the same commit. Results name the resolved sha and ref. complete=false means the totals are lower bounds (cut says why).

Read a page with get_wiki_page; cite its wiki url. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `archive`: ```json { "permissions": { "allow": [ "mcp__archive__find_failing_patches", "mcp__archive__get_attachment", "mcp__archive__get_callers", "mcp__archive__get_contributor", "mcp__archive__get_doc_page", "mcp__archive__get_entry", "mcp__archive__get_message", "mcp__archive__get_thread", "mcp__archive__get_wiki_page", "mcp__archive__git_search", "mcp__archive__hybrid_search", "mcp__archive__list_sources", "mcp__archive__search_commitfest", "mcp__archive__search", "mcp__archive__search_docs", "mcp__archive__search_symbols", "mcp__archive__search_wiki", "mcp__archive__code_search", "mcp__archive__read_file", "mcp__archive__list_files", "mcp__archive__get_commit", "mcp__archive__search_commits" ], "ask": [ "mcp__archive__retrieve_context", "mcp__archive__commit_buildfarm_status", "mcp__archive__commit_history", "mcp__archive__git_log", "mcp__archive__cross_reference", "mcp__archive__whats_new", "mcp__archive__blame" ], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__archive__retrieve_context`: private-data, untrusted-input - `mcp__archive__commit_buildfarm_status`: untrusted-input - `mcp__archive__commit_history`: untrusted-input - `mcp__archive__find_failing_patches`: untrusted-input - `mcp__archive__get_attachment`: private-data, untrusted-input - `mcp__archive__get_callers`: private-data, untrusted-input - `mcp__archive__get_contributor`: private-data, untrusted-input - `mcp__archive__get_doc_page`: private-data, untrusted-input - `mcp__archive__get_entry`: private-data, untrusted-input - `mcp__archive__get_message`: private-data, untrusted-input - `mcp__archive__get_thread`: private-data, untrusted-input - `mcp__archive__get_wiki_page`: untrusted-input - `mcp__archive__git_log`: private-data, untrusted-input - `mcp__archive__git_search`: private-data, untrusted-input - `mcp__archive__hybrid_search`: private-data, untrusted-input - `mcp__archive__list_sources`: private-data, untrusted-input - `mcp__archive__search_commitfest`: untrusted-input - `mcp__archive__search`: private-data, untrusted-input - `mcp__archive__search_docs`: private-data, untrusted-input - `mcp__archive__search_symbols`: private-data, untrusted-input - `mcp__archive__search_wiki`: untrusted-input - `mcp__archive__code_search`: private-data - `mcp__archive__read_file`: private-data - `mcp__archive__list_files`: private-data - `mcp__archive__get_commit`: private-data, untrusted-input - `mcp__archive__search_commits`: private-data, untrusted-input
