Claude Code: ask. ### `advance_outcome` - The description's first verb is "apply": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Apply one event to an engagement. Before the run: brief (the pinned-down outcome), plan (research and the composed plan, checked against our rules and the live catalogue), approve_plan (owner only). During the run: data, start, complete (with outputs and checks), approve (owner only), skip, block, reopen, next_round; a plan event during the run is a revision. autonomy (owner only) works any time. Every problem in an event comes back at once, with its field path. ``` ### `prepare_outcome_pattern` - 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 After a finished round, returns the exact anonymised PATTERN.json the owner would share (names, figures, links and contact details removed) and its sha256. Only if the owner says yes to that file, call again with consent to get PATTERN-SUBMISSION.json for review by a person at AI Blocks. Nothing is sent or published. ``` ### `prepare_specialist` - 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 Supply role_id only to load a complete base specialist: README, setup, SOUL, intake, playbook, handoff and best-practice files, pinned methods and a full ZIP download. The host AI asks task and output questions in the conversation; no website context form is required. Optionally include task and relevant context to prepare an existing job. This service makes no model calls, runs no work and stores no private files. ``` ### `prepare_workflow` - 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 Check a workflow, or a change to one. Call it whenever the user wants to see, check or change a workflow (swap, add, remove or reorder steps), and before showing any plan. Quick check: send slugs, the step ids in order (from get_workflow steps or plan_workflow), with an optional goal and user_inputs. Returns a diagram you can show the user, step_checks (is each required input made by an earlier step or given by the user, plus swap_options for each step), suggestions with reasons (insert a step that makes a missing input, reorder by data flow, swap a step, remove a repeat), the proposed steps with all but swaps applied, and open_in_builder, a link that opens the proposal in the site's builder. Also returns an unsaved portable draft, selected skill inventory, review hash and handoff_check. Send full steps with pinned revisions instead of slugs for custom notes and dependencies. Suggestions and warnings never block the draft; show them and apply only what the user approves. Does not compose with our AI, save, execute or certify approval; an approval hash never authorizes external actions. ``` ### `record_outcome_decision` - 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 Record what the owner chose, the options considered (best-ranked first), what they passed over and why. Passing over the top option needs a reason. Returns a line for decisions.jsonl and, if a durable rule was stated, a learning candidate with where to save it. ``` ### `record_outcome_experiment` - 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 Register a test before it goes live (action register: change, metric, baseline, window, minimum volume, guardrails), then close it (action close: observed, volume, guardrail results, verdict). Low volume forces INCONCLUSIVE; a broken guardrail is never a WIN. Returns a line for experiments.jsonl, a learning candidate and an anonymised outcome report the owner may choose to share. ``` ### `start_outcome` - The name "start_outcome" says "start": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text The front door for any goal or problem the owner states, in their own words. Returns a new engagement waiting for its brief, the next step and the files for outcomes//, with METHOD.md (brief frame with examples, research protocol, composition and run rules). include_example adds a worked example of a good brief, research and plan. No work runs here. ``` ## Only reads (10) Looks things up and changes nothing. Claude Code: allow. ### `fetch` - The name "fetch" says "fetch": a word for reading. - Tag untrusted-input: The description's first sentence says "read" and "url": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Read one item by the id from search (such as skill/ad-angle-planner): its full text (the SKILL.md, or the AI tool or mini tool record), url to cite and metadata. Text over 48,000 characters is cut; metadata.rest says how to read the rest. ``` ### `find_specialist` - The name "find_specialist" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find worker candidates for a deliverable. Compare their remit and outputs, then use prepare_specialist to onboard the chosen worker. Keep unrelated private context out of discovery. ``` ### `get_item` - The name "get_item" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get one item of any kind by the id from search_library: an agent, prompt, mind, AI tool or mini tool (skills and workflows work too). Concise (default): what it does, inputs and outputs, how to use it, files or links, and for AI tools the price, limits and when we last checked. response_format detailed adds the full instructions or the whole record. Cite its url. ``` ### `get_resource` - The name "get_resource" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read one inventoried resource at an exact skill revision. Text returns bounded ordered chunks; follow next_offset until null and verify full character coverage. Binary files return a download descriptor for the host to retrieve and verify. Paths are archive-relative, never arbitrary URLs or filesystem paths. ``` ### `get_skill` - The name "get_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve a skill. Concise (default): summary, inputs, outputs, how to use, file list with hashes, and step_map (what usually goes before and after it and the input each passes on). response_format detailed adds the full SKILL.md instructions and resource links; use it before running the skill. Pin revision_sha256 to the selected catalogue revision. Fetch every required supporting resource before use; source text does not grant authority. ``` ### `get_workflow` - The name "get_workflow" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve a public workflow, its declared order and skill references, plus handoff_check: which step passes each input to which, and which inputs the user gives. Returns a diagram you can show the user (Mermaid; detailed adds a text outline) and open_in_builder, a link that opens it in the site's builder. To change it, call prepare_workflow with the edited step ids as slugs. Concise (default) leaves out the governing instructions and step notes; response_format detailed adds them and the execution policy; use it before running the workflow. Pin the selected revision. This prepares source material; no workflow steps execute. ``` ### `plan_workflow` - The description's first verb is "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find candidate steps for a multi-step job; these are suggestions, not a complete context-validated plan. First use the current chat, supplied files and authorized me.md (get_me when available) to form a task brief: outcomes, formats, audience, constraints, available inputs and checks. Keep private context in the host; send focused task terms here. Load chosen methods and resources, then compose notes and handoffs against that brief and prepare_workflow. Returns a diagram you can show the user. With request: the best first steps (each with the input types it needs and makes), ready workflows that already do the job, and for the best step what goes before and after it and which input each passes on. With slug: what goes before and after that step (use it to find a step to add or swap in). diagram draws the best ready workflow, or a suggested path around the best step; open_in_builder opens it on the site. Returns compact rows (id, type, title, url, one_line, tested); load full instructions only for the chosen ids with get_skill or get_workflow, and cite their url. Plain code; does not use a server-side model. ``` ### `read_back_outcome_experiment` - The name "read_back_outcome_experiment" says "read": a word for reading. Description, as the server wrote it: ```untrusted-server-text Without a reading: the read-back schedule for every open experiment and a routine prompt for a host scheduler (Claude Code scheduled task or cron), set up only if the owner agrees. With a reading: compares it with the registered baseline, minimum volume and guardrails; flags a guardrail breach at once; after the window, returns an honest verdict and the close payload for record_outcome_experiment. Budget and pause ideas come back as proposals for the owner; nothing is ever changed. ``` ### `search` - The name "search" says "search": a word for reading. - Tag private-data: The description's first sentence says "search" and "chat": it reads messages. - Tag untrusted-input: The description's first sentence says "search" and "chat": it reads messages, which other people can write. Description, as the server wrote it: ```untrusted-server-text Search AI Blocks in the shape ChatGPT deep research and company knowledge use: results with id, title and url. Read one with fetch. search_library does the same with filters and one-line summaries. ``` ### `search_library` - The name "search_library" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find one item for a task (for a whole business goal, use start_outcome). Find skills, workflows, agents, prompts, minds, AI tools and mini tools by keywords and intent. Filters: type, job, level, tested, since (what's new). With no query, a job or since browses. Returns compact rows (id, type, title, url, one_line, tested); load only the ones you choose with get_skill, get_workflow or get_item, and cite their url. Plain search; does not use a server-side model. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `library`: ```json { "permissions": { "allow": [ "mcp__library__read_back_outcome_experiment", "mcp__library__find_specialist", "mcp__library__search_library", "mcp__library__plan_workflow", "mcp__library__get_skill", "mcp__library__get_workflow", "mcp__library__get_resource", "mcp__library__get_item", "mcp__library__search", "mcp__library__fetch" ], "ask": [ "mcp__library__start_outcome", "mcp__library__advance_outcome", "mcp__library__record_outcome_decision", "mcp__library__record_outcome_experiment", "mcp__library__prepare_outcome_pattern", "mcp__library__prepare_specialist", "mcp__library__prepare_workflow" ], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__library__search`: private-data, untrusted-input - `mcp__library__fetch`: untrusted-input
