MCP tools · 29 exposed · ~5,216 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 →

import-entries ~237

Max 50 entries per bulk call—split large catalogs into batches of ~50 to avoid oversized tool payloads. For full re-import: delete-entries once, then set-entries in 50-entry chunks; or replace-entries with deleteOrphans=false until the final batch (deleteOrphans=true). Alias for replace-entries (mode=replace). Pass filter as scope; send up to 50 entries per call.

list-projects ~110

Call first. Lists projects in ~/.mcp-architector with projectId, description, moduleCount, updatedAt, isCurrent, forbidden. Match this workspace by folder name (query).

Preview or apply in-repo refactor sync to architector data (no workspace access). Default dryRun=true. Workflow: (1) scan with file/text to list hits, (2) build 1-3 mutation ops, (3) dryRun preview, (4) apply with dryRun=false and confirm=true. Mutations: move-file, replace-path-prefix, rename-text, patch-entry, merge-files, remove-file-ref. Orphan entries with empty refs.files and no entryIds are deleted.

replace-entries ~258

Max 50 entries per bulk call—split large catalogs into batches of ~50 to avoid oversized tool payloads. For full re-import: delete-entries once, then set-entries in 50-entry chunks; or replace-entries with deleteOrphans=false until the final batch (deleteOrphans=true). Idempotent sync for up to 50 entries in scope; optionally delete orphans not in this batch. Match by upsertBy (default kind+title). For large catalogs use deleteOrphans=false on intermediate batches, true only on the last batch.

search-entries ~196

Compact navigation search over entries by title, summary, kind, and tags. Returns snippet, matchedIn, slices, and moduleName per hit—use get-entry for full payload. Prefer get-slice when you know the category (api, domain). Filters (moduleName, kind, tags) narrow agent context. Default limit 10.

set-entries ~239

Entries need vertical structure: create modules via set-project-architecture / set-module-details before or when adding entries. Set refs.moduleName to an existing module name from list-modules. Run validate after edits to find entries-without-modules, entry-unlinked, or empty slices. Max 50 entries per bulk call—split large catalogs into batches of ~50 to avoid oversized tool payloads. For full re-import: delete-entries once, then set-entries in 50-entry chunks; or replace-entries with deleteOrphans=false until the final batch (deleteOrphans=true). Set refs.moduleName per entry, or pass top-level moduleName as default. Prefer set-entries in 50-entry chunks over one huge replace-entries payload.

NameTypeReqDescription

set-entry ~356

Entries need vertical structure: create modules via set-project-architecture / set-module-details before or when adding entries. Set refs.moduleName to an existing module name from list-modules. Run validate after edits to find entries-without-modules, entry-unlinked, or empty slices. Creates or updates one canonical project fact (entry). Use when you discovered a concrete fact while working. Do not use for module structure—use set-module-details. Do not copy module.description into summary; link via refs.moduleName only. Upsert: pass id to update, or omit id to match by kind+title or create new. Example: kind=http-endpoint, title='POST /orders', summary='Creates order', refs.moduleName='orders', refs.files=['src/OrderController.java'].

NameTypeReqDescription
idstringEntry uuid; omit to upsert by kind+title or create new
kindstringyesFree-form type: http-endpoint, glossary, entity, flow, script, godot-scene, etc. Builtin slice list-slices shows recommended kinds per sliceId

set-module-data-flow ~138

Patches dataFlow for one module (dependsOn is canonical; providesTo is recomputed). Syncs module file dependencies. Prefer over set-project-architecture for single-module graph edits.

No examples provided.

set-module-details ~386

Creates or updates one vertical module (files, dependencies, dataFlow sync). IMPORTANT: Slices (api, domain, persistence) are built from entries, not from module text. When adding or updating a module, also add entries this module owns: pass facts[] (http-endpoint, entity, glossary, …) in this call (max 50 per call), or call set-entry / set-entries in 50-entry batches with refs.moduleName=<module name>. Max 50 entries per bulk call—split large catalogs into batches of ~50 to avoid oversized tool payloads. For full re-import: delete-entries once, then set-entries in 50-entry chunks; or replace-entries with deleteOrphans=false until the final batch (deleteOrphans=true). Without entries, get-slice will be empty for this module. After edits call validate to verify links. Does not replace other modules. Prefer over set-project-architecture for single-module edits.

NameTypeReqDescription

set-project-architecture ~258

Creates or updates vertical module structure (components and dataFlow)—not horizontal facts. By default merges modules and dataFlow by name; omit dataFlow to keep existing flow. Use replaceModules or replaceDataFlow for full replace. For one module use set-module-details or set-module-data-flow. For bulk flow rebuild use rebuild-data-flow. Each new module still needs entries—use set-module-details with facts[] or set-entries after bulk structure. For APIs, domain terms, scripts use set-entry + get-slice—not this tool. projectId is required—call list-projects first. Never use default-project. Do not duplicate entry text in module descriptions.

set-slice ~188

Saves a custom slice definition (filter only—no items). Items always live in entries. Use when built-in slices (api, domain, …) are not enough, e.g. filter kinds godot-scene + tag gameplay. Do not store duplicate entry text here. get-slice reads entries through this filter.

NameTypeReqDescription

No examples provided.

validate ~331

Run after set-project-architecture, set-module-details, set-entry, or set-entries. Returns a compact report (summary, stats, issues by kind)—no need to load the full project in the agent. Checks only known rules: dataFlow consistency, module↔entry links, module detail files, entry index drift, empty api/domain/persistence slices, entry slice coverage, optional module-too-few-entries when moduleEntryMin is set. If catalog JSON is corrupt, run fix-data first. Fix issues[] then call validate again.

NameTypeReqDescription

validate-import ~198

Dry-run validation for a proposed import batch (max 50 entries). Max 50 entries per bulk call—split large catalogs into batches of ~50 to avoid oversized tool payloads. For full re-import: delete-entries once, then set-entries in 50-entry chunks; or replace-entries with deleteOrphans=false until the final batch (deleteOrphans=true). Checks duplicate upsert keys and unknown moduleName refs without writing.
