Catalogued

  • Wiki.js MCP (issue #3840) - ni-c stdio server for self-hosted Wiki.js 2.x: 62 tools over pages, version history, tags, assets, comments, users, groups and system settings via the GraphQL API. grep_pages compensates for title-only default search, update_page is compare-and-swap, destructive/admin ops need server-issued confirmation tokens, WIKIJS_READ_ONLY and WIKIJS_ALLOWED_PATHS confinement, no API-key-minting tool. npm @ni-c/wikijs-mcp v0.1.2, MIT, registry io.github.ni-c/wikijs-mcp v0.1.0-v0.1.2. Repo 0 stars, created Aug 30, 2026. Guide at hermes/mcp/servers/external/wikijs-mcp/, relevance ★★.

  • imap-mcp (issue #3843) - ni-c stdio server for any IMAP mailbox with a deliberate no-send design: folders, search, read via BODY.PEEK (unread state preserved), agent-side seen tracking, attachment saves, draft-only replies. Messages arrive nonce-fenced with SPF/DKIM/DMARC verdicts, prompt-injection-shape flags and defused markdown images. Writes off unless IMAP_READ_ONLY=false, deletes via human elicitation, 11 tools (6 essential mode). npm @ni-c/imap-mcp v0.2.0, MIT, registry io.github.ni-c/imap-mcp v0.2.0. Repo 0 stars, created Aug 26, 2026. Guide at hermes/mcp/servers/external/imap-mcp/, relevance ★★.

  • Tactiq MCP (mcp.so feed catch-up, listed Aug 15) - hosted meeting transcript intelligence: search, read and summarise Google Meet, Zoom and Teams transcripts across the whole meeting history. Endpoint mcp.tactiq.io live-verified (anonymous initialize 401 missing_token = sign-in auth, Jitsu/Taskfolk class). Verified Claude connector (two-click connect), works with Cursor, ChatGPT, Gemini and any MCP client. Free plan; paid tiers lift the plan gate on summary-content reads (free/Pro plans can find meetings but not read summary content). No public repo. Guide at hermes/mcp/servers/external/tactiq-mcp/, relevance ★★★.

  • Gemina MCP (mcp.so feed catch-up, listed Jul 21) - hosted document intelligence: 13 tools to extract, tag, search and aggregate invoices, receipts, contracts, forms and custom templates. OAuth 2.1 sign-in or API key at api.gemina.co/api/v1/mcp/, free FileTag tier, EU/US/Israel/Asia data residency. Tool names recovered from the listing state (extract_document, files_create_upload, files_create_extraction_upload, get_extraction_result, list_extractions, index_document, query_documents, aggregate_documents, tag_file, tag_url, custom_template, submit_extraction_feedback, explain_* helpers). No public repo. Guide at hermes/mcp/servers/external/gemina-mcp/, relevance ★★.

  • HasData MCP (mcpservers.org /all catch-up; resolves the Aug 29 midday "future catch-up candidates" note) - hosted web-data gateway: 40+ connector tools over real estate (zillow_listing/property, redfin_listing/property), hospitality (airbnb_listing/property, booking_place/search), hiring (indeed_job/listing, glassdoor_job/listing), local business (yelp_place/reviews, yellowpages_place/search), e-commerce (shopify_collections/products, amazon_), search and trends (google_serp family, google_maps_, google_trends_search, google_travel_, bing_serp, duckduckgo_serp) and social (tiktok_, instagram_*, google_images, web_scraping). Endpoint mcp.hasdata.com/mcp, x-api-key header (HASDATA_API_KEY), connector selection via ?apis= param, credit-priced. Tool names recovered from docs.hasdata.com/mcp-server. Guide at hermes/mcp/servers/external/hasdata-mcp/, relevance ★★.

  • Contextflo MCP (mcp.so feed catch-up, listed Jul 9) - governed team data queries: connect BigQuery, Snowflake, Postgres, Redshift, Databricks or ClickHouse (or CSV upload), ask questions and build live auto-refreshing dashboards in chat, with table-level access control. Endpoint mcp.contextflo.com/mcp live-verified (anonymous initialize returns JSON-RPC 401 Authentication required). Docs at contextflo.com/docs with MCP client pages for Claude and ChatGPT. No public MCP repo (0-star org repos). Capability-level tools table with caveat. Guide at hermes/mcp/servers/external/contextflo-mcp/, relevance ★★.

Mechanics

  • Cross-reference: bare-brand grep over index.md with variant generation (hyphen->space, stripped, dot->space, bare brand) plus full-line context reads to distinguish catalogued vs skip-prose vs false-positive hits; 135 unique slugs checked.
  • Registry verification: npm registry (versions, publish dates), official MCP registry search (confirmed io.github.ni-c/wikijs-mcp v0.1.0-v0.1.2 and io.github.ni-c/imap-mcp v0.2.0), GitHub API (stars, license, creation dates).
  • Endpoint probing: batch-probe.py on mcp.tactiq.io (401 missing_token) and app.tactiq.io/mcp (405, app path); direct initialize on mcp.contextflo.com/mcp (401 Authentication required). 401-is-liveness doctrine applied for both hosted services.
  • Tool-name recovery: HasData from the vendor's official docs page; Gemina from the mcp.so listing state; Contextflo and Tactiq as capability-level tables with the explicit caveat line (anonymous enumeration refused).
  • Index patched with one atomic Python patcher (assert-before-write: last-updated line, top sweep section, docs-links tail block); guides validated with bundled validate-guides.py (6/6 PASS) plus See Also dir-existence and label-accuracy checks against real target titles (7 labels corrected pre-commit).
  • Shift label collision check: grep for "Night Cron Sweep" before naming - no Aug 30 night section existed.
