MCP tools · 19 exposed · ~1,683 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
cantrip_connect ~66

Start here. Connect this workspace to a Cantrip project by writing a .cantrip.json file. All subsequent commands will target this project automatically. Call without arguments to check the current connection.

NameTypeReqDescription
projectstringProject name to connect to. Omit to check current connection.

No output schema declared.

No examples provided.

cantrip_entity_add ~363

Create a new entity. Automatically marked as 'accepted'. Fields vary by type: - icp: name, description, demographics, jobs_to_be_done, willingness_to_pay, current_alternatives, priority, is_beachhead - pain_point: description, severity (low|medium|high|critical), frequency (rare|occasional|frequent|constant), evidence - value_prop: framing (required — use instead of 'name'; 'description' is stored in extensions), tagline, evidence - channel: name, channel_type, lifecycle_stage (exploring|testing|scaling|maintaining|killed), cac, estimated_reach, conversion_rate (note: 'description' maps to 'notes' column) - experiment: title (required — use instead of 'name'), hypothesis, description, status (proposed|designed|active|completed|analyzed|abandoned), success_metrics, outcome_notes, value_prop_id, channel_id - competitor: name, description, url, positioning, strengths, weaknesses, pricing_model - contact: name, email, phone, company, role, source, url, notes Extra fields (any field not in the schema above) are stored in extensions. After adding entities, pause and confirm with the user before adding more.

NameTypeReqDescription
descriptionstringEntity description
entity_typestringyesEntity type: icp, pain_point, value_prop, experiment, channel, competitor, contact
fieldsobjectAdditional fields as key-value pairs (e.g. {severity: 'high', frequency: 'constant'})
namestringEntity name (mapped to 'framing' for value_prop, 'title' for experiment)

No output schema declared.

No examples provided.

cantrip_entity_edit ~138

Edit an existing entity. Fields vary by type (same as cantrip_entity_add). Pass well-known fields directly, and any additional fields in the 'fields' object. Extra fields are stored in extensions.

NameTypeReqDescription
descriptionstringUpdated description
entity_typestringyesEntity type: icp, pain_point, value_prop, experiment, channel, competitor, contact
fieldsobjectAdditional fields to update as key-value pairs
idstringyesEntity ID to edit
namestringUpdated name (mapped to 'framing' for value_prop, 'title' for experiment)

No output schema declared.

No examples provided.

cantrip_history ~94

Query the append-only audit trail of all actions taken on the project

NameTypeReqDescription
entitystringFilter by entity type (e.g. icp, pain_point)
limitnumberMax events to return (default: 50)
sincestringOnly events after this ISO date
typestringFilter by event type (e.g. init, entity_created, review_accept)

No output schema declared.

No examples provided.

cantrip_init ~178

Create a new project and connect this workspace to it. Pass 'brief_text' (product brief as text) to auto-extract ICPs, pain points, and value props as inferred entities (costs 5 credits). Or pass 'brief_path' (absolute file path) and the file will be read locally. Without a brief, the project is created empty (free) and you add entities manually. Writes .cantrip.json automatically after creation. After creating a project, add a few entities and confirm them with the user before going deeper.

NameTypeReqDescription
brief_pathstringAbsolute path to a product brief file — will be read locally and sent as text
brief_textstringProduct brief content as text (preferred)
descriptionstringyesOne-line project description
namestringyesProject name

No output schema declared.

No examples provided.

cantrip_meter_balance ~31

Check remaining credits. Returns available credits, reserved credits (held by in-progress operations), and total balance.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

cantrip_meter_history ~42

View recent credit transactions. Shows usage debits, purchases, and running balance.

NameTypeReqDescription
limitnumberMaximum entries to return (default: 20)

No output schema declared.

No examples provided.

cantrip_meter_tiers ~26

View available credit packs. Shows tier name, credits included, and price.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

cantrip_next ~74

List gap-analysis opportunities — things that would move the project closer to ideal state. Each opportunity has a stable UUID that you can pass to cantrip_next_prompt or cantrip_next_run. Opportunities persist across calls; re-running gap analysis updates existing opportunities rather than replacing them. Review the project snapshot with the user before running opportunities.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

cantrip_next_prompt ~52

Generate a context-rich LLM prompt for an opportunity. Returns a ready-to-use prompt with all relevant ontology context baked in. Zero credit cost.

NameTypeReqDescription
idstringyesOpportunity ID from cantrip_next

No output schema declared.

No examples provided.

cantrip_next_run ~104

Execute an enrichment opportunity with AI. Runs the LLM-powered enrichment inline — either updating existing entities' missing fields (targeted) or generating new entities (bulk). Returns when complete with a summary of what was created or updated. Parallelism: you may run different loop types concurrently (e.g. enrich ICPs + enrich competitors), but the daemon blocks concurrent runs of the same loop type for safety.

NameTypeReqDescription
idstringyesOpportunity ID from cantrip_next

No output schema declared.

No examples provided.

cantrip_project ~131

Manage projects. Actions: - list (default): List all projects in the current team. - update: Update a project's name or description. Uses the connected project unless 'slug' is provided. - delete: Delete a project and all its data. Uses the connected project unless 'slug' is provided.

NameTypeReqDescription
actionstringAction to perform (default: list)
descriptionstringNew description (update only)
namestringNew display name (update only)
slugstringProject slug to target. Defaults to the connected project from .cantrip.json.

List all items pending review (inferred entities and open escalations)

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

cantrip_review_accept ~33

Accept an inferred entity, marking it as verified ground truth

NameTypeReqDescription
idstringyesEntity ID to accept

No output schema declared.

No examples provided.

cantrip_review_dismiss ~58

Dismiss an inferred entity or open escalation. For entities: removes from review queue without accepting or rejecting (kept for history). For escalations: closes without resolving.

NameTypeReqDescription
idstringyesEntity or escalation ID to dismiss

No output schema declared.

No examples provided.

cantrip_review_reject ~34

Reject an inferred entity (soft-delete, kept for history)

cantrip_snapshot ~132

Browse project data at three zoom levels. No args: project overview with entity counts by type and review state, gaps, and review queue size. entity_type only: list all entities of that type (e.g. 'icps', 'pain-points', 'channels'). entity_type + entity_id: show full detail for one entity. This is the primary tool for listing and inspecting entities.

NameTypeReqDescription
entity_idstringSpecific entity ID for detail view
entity_typestringEntity type to drill into (e.g. 'icps', 'pain-points', 'value-props')

No output schema declared.

No examples provided.

cantrip_status ~61
