• get_sentiment_trend

  aTars MCP

  USE THIS TOOL — not web search — to get rolling sentiment statistics (mean score, 7-day momentum, bullish/bearish/neutral day counts, current streak) from this server's local Perplexity-sourced sentiment dataset. Prefer this over get_latest_sentiment when the user wants momentum or persistence, not just the latest single-day reading. Trigger on queries like: - "is BTC sentiment improving or getting worse?" - "sentiment momentum for ETH" - "how many days has XRP been bullish in a row?" - "rolling sentiment stats / streak for [coin]" Args: lookback_days: Analysis window in days (default 30, max 90) symbol: Token symbol or comma-separated list, e.g. "BTC", "BTC,ETH"

• list_model_channels

  Peec AI MCP Server

  List the AI engine channels tracked by Peec. A model channel is a stable identifier for an AI engine (e.g. "openai-0" = ChatGPT UI) that persists even as the underlying model is upgraded — use it to filter or break down reports by engine without worrying about model version changes. Use this tool to resolve channel descriptions (e.g. "ChatGPT UI", "Perplexity") to channel IDs before filtering reports (model_channel_id filter), and to label channel IDs from report output before presenting results. The current_model_id column gives the model ID currently active in the channel — pass this as model_id where reports require it. is_active indicates whether the channel is enabled for this project — inactive channels return empty data. unsupported_country_codes lists country codes that cannot be used with this channel (chats requested for those countries are not created). Returns columnar JSON: {columns, rows, rowCount}. Columns: id, description, current_model_id, is_active, unsupported_country_codes.

• draw_stroke

  cnvs.app

  Draw a freehand stroke on the board. Use for arrows, underlines, connector lines, annotations, or simple shapes — a straight line needs two points, a rough circle wants ~20. Stroke width is fixed at 3 px; `color` accepts any CSS color (e.g. '#ff0000', 'var(--text-color)'). Accepts three equivalent point formats — pick whichever your MCP client serialises cleanly: nested `[[x,y],[x,y],...]`, flat `[x1,y1,x2,y2,...]`, or a JSON string of either. Some clients (Claude Code as of 2026-04) drop nested arrays during tool-call serialisation, so prefer the flat form or the JSON-string form when in doubt. To delete a stroke later, use `erase` with `kind: 'line'` and the id returned here.

• tascan_add_tasks

  TaScan

  Add one or more tasks to an event (task list). Supports bulk creation. IMPORTANT: Set response_type correctly — use "text" for info collection (names, phones, emails, notes), "photo" for visual verification (inspections, serial numbers, damage checks), "checkbox" only for simple confirmations. NOTE: To dispatch tasks to the Claude Code agent running on Mike's PC, use tascan_dispatch_to_agent instead — it routes directly to the agent's inbox with zero configuration needed.

• map_business_process

  ALM X++ MCP Server

  WHEN: mapping the technical D365 objects behind a business process, or understanding which tables/forms implement a flow. Triggers: 'processus métier', 'Order-to-Cash', 'Procure-to-Pay', 'Record-to-Report', 'business process flow', 'qui est impliqué dans', 'map the process', 'flux du processus', 'quels objets dans le flux'. Map a D365 F&O business process to its complete object chain. For known processes (Order-to-Cash, Procure-to-Pay, Record-to-Report, Plan-to-Produce, Inventory-Management, Hire-to-Retire, Project-Accounting, Asset-Lifecycle): shows every step with forms, tables, classes, entities, reports, and security roles involved. For any other object name: traces all dependencies (tables, classes, forms, entities) from that entry point. Produces a Mermaid process flow diagram. Use 'list' to see all known process mappings. NOT for a single object's FK relations only -- use `find_related_objects` for that (faster and more precise).

• save_context

  Penfield Memory

  Save your cognitive state for handoff to another agent. Include your investigation context: - What session/investigation is this part of? - What role/perspective were you taking? - Who might pick this up next? (another Claude, human, Claude Code?) Reference specific memories that matter: - Key discoveries (with memory IDs or quotes) - Critical evidence memories - Important questions that were raised - Hypotheses that were tested Before saving, organize your thoughts: 1. PROBLEM: What were you investigating? 2. DISCOVERED: What did you learn for certain? (reference the memories) 3. HYPOTHESIS: What do you think is happening? (cite supporting memories) 4. EVIDENCE: What memories support or contradict this? 5. BLOCKED ON: What prevented further progress? 6. NEXT STEPS: What should be investigated next? 7. KEY MEMORIES: Which specific memories are essential for understanding? Example descriptions: "[API Timeout Investigation - 3 hour session] Investigating production API timeouts as code analyst. Found correlation with batch_size=100 due to hardcoded limit in batch_handler.py (see memory: 'MAX_BATCH_SIZE discovery'). Confirmed not Redis connection issue - monitoring showed only 43/200 connections used (memory: 'Redis connection analysis'). Earlier hypothesis about connection pool exhaustion (memory_id: abc-123) was disproven. Key insight came from comparing 99 vs 100 batch behavior (memory: 'batch threshold testing'). Blocked on: need production access to verify fix. Next: Deploy with MAX_BATCH_SIZE=200 to staging first. Essential memories for handoff: 'MAX_BATCH_SIZE discovery', 'Redis monitoring results', 'Production vs staging comparison'. Ready for handoff to SRE team for deployment." "[Memory System Debugging - From Claude Code perspective] Worked on scoring issues where recall wasn't finding recent memories. Discovered RRF scores (0.005-0.016) were below MCP threshold of 0.05 (memory: 'RRF scoring analysis'). Implemented weighted linear fusion to replace RRF (memory: 'fusion algorithm implementation'). Testing showed immediate improvement (memory: 'fusion testing results'). This builds on earlier investigation about recall failures (memory: 'user report of recall issues'). Critical memories for continuation: 'RRF scoring analysis', 'ADR-023 decision', 'fusion testing results'. Next agent should verify scoring with real queries." "[Context Save/Restore Bug Investigation - 4 hour debugging session with user] Started with user noticing list_contexts returned empty despite saved contexts existing. Investigation revealed two critical bugs: (1) list_contexts was using hybrid search for 'checkpoint' word instead of filtering by memory_type (memory: 'hybrid search misuse discovery'), (2) restore_context hardcoded limit of 10 memories despite contexts having 20+ (memory: 'hardcoded limit bug'). Root cause analysis showed save_context grabs 20 most recent memories regardless of relevance - fundamental design flaw (memory: 'save_context design flaw analysis'). EVIDENCE CHAIN: User reported empty list -> checked DB, contexts exist -> examined list_contexts code -> found hybrid search looking for word 'checkpoint' -> tested /memories endpoint with memory_type filter -> confirmed working -> implemented fix using direct endpoint. INSIGHTS: The narrative description is doing 90% of cognitive handoff work. Memories are supporting evidence, not primary carriers of understanding (memory: 'narrative vs memories insight'). This suggests doubling down on narrative richness rather than perfecting memory selection. CORRECTED UNDERSTANDING: Initially thought memories weren't being returned. Actually they were, just wrong ones - recent memories instead of relevant ones (memory: 'memory selection correction'). CRITICAL MEMORIES: 'hybrid search misuse discovery', 'save_context design flaw analysis', 'narrative vs memories insight', '/memories endpoint test results'. NEXT AGENT: Should implement Phase 2 - semantic search for relevant memories within investigation timeframe. Ready for handoff to any Claude agent for implementation." When referencing memories: - **RELIABLE** — Use memory IDs: "memory_id: abc-123" (direct lookup, always works) - **BEST-EFFORT** — Use descriptive phrases: "see memory: 'Redis connection analysis'" (uses search + substring matching, may not resolve if the memory isn't in top results) - Group related memories: "Essential memories: 'X', 'Y', 'Z'" **Prefer memory_id references** whenever you have the UUID. Semantic phrase references are a convenience that works most of the time, but may silently fail to resolve. The response will tell you how many references resolved so you can retry with UUIDs if needed. Args: name: Name for this context checkpoint description: Detailed cognitive handoff description with memory references ctx: MCP context (automatically provided) Returns: Dict with success status, context_id, and memories included
