Claude Code: allow. ### `compare_peptides` - The name "compare_peptides" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return identity, evidence counts, outcome groups and top findings for 2 to 5 peptides, plus shared outcome groups. Use this for a comparison in one call. Use get_peptide_brief instead for a detailed summary of one peptide. The result compares evidence without ranking peptides as better or worse. Each finding has an evidence class: human, animal, laboratory or predicted. A count of 0 human findings means no checked human findings within the filters or outcome group. It does not mean that no human study exists. Each MCP column includes the largest 8 outcome groups, or 5 for 4 or 5 peptides. Each column includes 2 top findings for 2 or 3 peptides, or 1 for 4 or 5 peptides. Use get_evidence_map for all outcome groups or search_findings for more findings. ``` ### `get_changes` - The name "get_changes" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return record change events in sequence order. Use this to synchronize data after since_seq, with 0 for full history. Without since_seq, the response gives the newest page. next_since_seq supplies the continuation position. Use get_freshness instead for source import times, or get_record with as_of_seq for an earlier record. ``` ### `get_community_practice` - The name "get_community_practice" says "get": a word for reading. - Tag private-data: The description's first sentence says "return" and "note": it reads notes. Description, as the server wrote it: ```untrusted-server-text Return what community sources report about how people use one peptide: uses, regimens (route, amount, how often, how long), reported side effects, cautions and regulatory status notes such as US compounding policy, each line with its sources. Community-reported, not tested in trials. Use it for use, dose, cycle and compounding questions, together with studied_doses from get_peptide_brief. Seller pages are never sources. A peptide can have no record. Default compact keeps key lines, and view="full" returns every line. ``` ### `get_evidence_map` - The name "get_evidence_map" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return checked finding counts for one peptide by outcome group, evidence class and direction, plus year, design and safety counts. Use this to inspect evidence coverage and gaps. Use search_findings instead for individual claims and source sentences, or compare_peptides for several peptides. Counts use administered findings only. The endogenous block counts measurements of the body's own peptide. Those measurements are not evidence about taking the peptide. Each finding has an evidence class: human, animal, laboratory or predicted. A count of 0 human findings means no checked human findings within the filters or outcome group. It does not mean that no human study exists. ``` ### `get_freshness` - The name "get_freshness" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return source import and extraction times from stored study results. Use this to inspect data freshness. Use get_changes instead for record events, or get_my_usage for caller quotas. lag_hours measures time since success, not upstream backlog. source_latest_known is not reported yet and remains null. ``` ### `get_my_usage` - The name "get_my_usage" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return the caller's plan, grants, quotas and usage in the current windows. Use this to inspect access limits and remaining allowances. Use get_freshness instead for source import times, or get_changes for record updates. This tool reports account access, not evidence coverage. ``` ### `get_peptide_brief` - The name "get_peptide_brief" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text For a dose question, use studied_doses together with get_community_practice. Return a precomputed summary of one peptide: identity, sequence, checked findings by evidence class, trials, key findings with citations, coverage and notices. regulatory gives approval by place and use, plus sport status. Use this for an overview of a known peptide. Use resolve_peptide first for an unclear name, search_findings for a specific outcome, or compare_peptides for 2 to 5 peptides. Counts and key findings use administered findings only. The key_findings_v0.4 rule excludes method-only outcome groups when other groups have findings. Its order is evidence class, design tier, analysis role, sample size, citations, then newer. coverage.checked_years gives the year span of checked papers. coverage.search_scope_years gives the search scope. Trials counted test the peptide. evidence_summary.trials.other_registry_entries counts entries that only measure or mention it. Notices describe coverage limits. Each finding has an evidence class: human, animal, laboratory or predicted. A count of 0 human findings means no checked human findings within the filters or outcome group. It does not mean that no human study exists. Returned doses are the doses that studies used, with species, route, design and source. ``` ### `get_record` - The name "get_record" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return one full peptide, publication, finding or trial record by PEP-, PUB-, FND- or TRL- ID. A peptide slug, PMID or NCT number also works. Use this for known records or fields omitted from compact results. Use resolve_peptide instead for an unclear name, or search_publications to find papers. as_of_seq selects an earlier data_seq. Use replay_query instead to repeat a saved search. ``` ### `replay_query` - The name "replay_query" says "query": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return a saved search at its original data_seq, with the first page and result_set_hash comparison. Use this to check whether a recorded query reproduces identical data. Use search_findings with as_of_seq instead for a new search at an earlier sequence, or get_record with as_of_seq for one earlier record. ``` ### `resolve_peptide` - The name "resolve_peptide" says "resolve": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return peptide IDs and name matches for a name, alias or code. Use this before other calls when the name is unclear. Use search_peptides instead to browse or filter many peptides. Matching order: exact alias, normalized alias, trigram similarity, then edit distance. Normalization ignores letter case, spaces, hyphens and symbols. Greek letters use their names, so α-MSH matches alpha-MSH. Edit distance allows at most 2 typing errors against featured peptides only, so retratutide finds retatrutide. Trigram and edit_distance matches are guesses. An ambiguous status returns candidates without selecting a peptide. ``` ### `search_findings` - The name "search_findings" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return checked findings with exact total_count and source sentences in included.passages. Each finding is one claim from one paper. Use this for specific outcomes, with filters for peptide, evidence class, design, claim type, peptide role, direction, outcome group, body system and year. Use search_publications instead for paper discovery, or get_peptide_brief for an overview. Each finding has an evidence class: human, animal, laboratory or predicted. A count of 0 human findings means no checked human findings within the filters or outcome group. It does not mean that no human study exists. Each finding has claim.peptide_role. administered means the study gave the peptide. endogenous_level means the study measured the body's own peptide, for example after vitamin D. Those measurements are not evidence about taking the peptide. The peptide_role=administered filter selects studies that gave it. included.publications supplies each source PMID or DOI for citation. complete is true only on the last page. Returned doses are the doses that studies used, with species, route, design and source. ``` ### `search_live_sources` - The name "search_live_sources" says "search": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Return live, unchecked papers from Europe PMC. Use this for gaps in database coverage or an explicit live literature search. Use search_publications instead for stored papers, or search_findings for checked claims. Live results have a separate unchecked label. ``` ### `search_peptides` - The name "search_peptides" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return peptides with identity and evidence counts. Use this to browse or filter by text, category, kind, evidence level, registry level or the curated launch list. Use resolve_peptide instead for one unclear name, or get_peptide_brief for one peptide summary. evidence_level comes only from checked findings of studies that gave the peptide. registry_level comes from registered trials that test the peptide and the curated phase. It says nothing about results. ``` ### `search_publications` - The name "search_publications" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return stored papers with citation identifiers and extraction status. Use this for paper discovery, publication dates or unchecked coverage. Use search_findings instead for checked claims and source sentences, or get_peptide_brief for a peptide overview. extraction_status identifies the layer: extracted is layer 1 with checked findings. queued and stored_only are layer 2 without checked findings. Layer 2 results carry contains_unchecked_papers. Abstract text appears only when the article license allows it. design_hint is an unchecked PubMed publication-type tag. profile describes the checked findings of a paper: evidence classes, designs, species and peptide roles. ``` ### `search_trials` - The name "search_trials" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return registered clinical trials with registry status, phase, posted-results status and peptide role. Use this for clinical development and trial records. Use search_findings instead for checked study results, or get_record for one full trial. The default role=tests lists and counts trials that test the peptide. role=measures and role=mentions return entries that only measure or name it. role=all includes every role. Those entries are not trials of taking the peptide. other_registry_entries signals their presence. Registration alone is not evidence of an effect. has_results identifies posted results. view=list gives a full trial list with up to 100 rows per page. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `pepbank`: ```json { "permissions": { "allow": [ "mcp__pepbank__resolve_peptide", "mcp__pepbank__get_peptide_brief", "mcp__pepbank__get_community_practice", "mcp__pepbank__search_peptides", "mcp__pepbank__search_findings", "mcp__pepbank__search_publications", "mcp__pepbank__search_trials", "mcp__pepbank__search_live_sources", "mcp__pepbank__get_record", "mcp__pepbank__get_evidence_map", "mcp__pepbank__compare_peptides", "mcp__pepbank__get_changes", "mcp__pepbank__replay_query", "mcp__pepbank__get_freshness", "mcp__pepbank__get_my_usage" ], "ask": [], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__pepbank__get_community_practice`: private-data - `mcp__pepbank__search_live_sources`: untrusted-input
