Home / Agent-Access Registry
Registry · Updated 21 August 2026
Not which vendors say "agentic" — which ones publish an interface an external agent can authenticate against and use. Every row below was checked against the vendor's own documentation on the date shown, and links to the specific page the finding rests on. Where we found nothing, we say so rather than leaving it blank.
The two categories where no vendor ships an agent interface are Pricing & Packaging and Sales Compensation — Layers 3 and 5 of the Agentic Commercial Model. They are also the two layers the model argues have to change first. Several of those vendors do expose REST APIs an agent can write through; none of them will sell you the interface. You build it yourself, or you don't have one.
| GTM & Sales Engagement | Layer 2 | 3 / 3 |
| Marketing Automation | Layer 2 | 5 / 5 |
| CRM & Pipeline | Layer 9 | 2 / 3 |
| Sales Enablement & Revenue Intelligence | Layer 4 | 2 / 3 |
| Customer Success & Adoption | Layer 7 | 3 / 5 |
| Billing & Usage Metering | Layer 6 + 8 | 2 / 5 |
| CPQ | Layer 3 | 1 / 3 |
| Pricing & Packaging Strategy | Layer 3 | 0 / 3 |
| Sales Compensation & Incentive Management | Layer 5 | 0 / 4 |

| m3ter | L6 + 8 · Billing & Usage Metering | None found | Documented | Documented | Source ↗ | 2026-08-21 | Full REST API with OAuth client-credentials and documented writes, but no first-party MCP server. Salesforce has signed a definitive agreement to acquire; no completion announcement found. |
| DealHub | L3 · CPQ | Third-party only | Documented | Documented | Source ↗ | 2026-08-21 | Documented REST APIs incl. Headless Quotes (generate and publish a quote from a backend system), but neither MCP nor "DealAgent" appears in the developer docs — DealAgent is marketing-side only. |
| PandaDoc | L3 · CPQ | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party hosted MCP server (mcp.pandadoc.com, EU variant) using OAuth consent; agents read, create and update documents and templates, scoped to the authenticated user’s regional account. |
| Qwilr | L3 · CPQ | Third-party only | Documented | Documented | Source ↗ | 2026-08-21 | REST API with bearer/JWT auth and write endpoints for Pages, taxes and webhooks; no first-party MCP server — only third-party wrappers such as Zapier MCP. |
| Ahoy | L9 · CRM & Pipeline | None found | None found | None found | None found | 2026-08-21 | No developer portal, API reference, webhook documentation or MCP server could be found; the site lists only end-user integrations with no documented programmatic access. |
| HubSpot | L9 · CRM & Pipeline | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party remote MCP server with scope-gated, admin-authorised read and write access to CRM objects and engagements — distinct from the in-product Breeze copilot. |
| Pipedrive | L9 · CRM & Pipeline | Official | Documented | Documented | Source ↗ | 2026-08-21 | Native first-party MCP server with per-client setup guides; access governed by authentication and permission settings, assistants can create or update records. |
| Catalyst (Totango) | L7 · Customer Success & Adoption | Third-party only | Documented | Documented | Source ↗ | 2026-08-21 | No first-party MCP server for Catalyst or the merged Totango entity, only third-party wrappers. Catalyst API v1 is GET-only; Totango’s HTTP, Touchpoints and SuccessPlay APIs accept writes via API key with no agent-specific scoping, confirmation or audit trail. |

No confirmation prompt or audit trail documented. |
| Planhat | L7 · Customer Success & Adoption | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party MCP server with ~10 tools including create/update/delete_model_record; access is the intersection of the OAuth client permissions and the user’s own. No automated confirmation step and no audit trail documented. |
| Vitally | L7 · Customer Success & Adoption | Official | Documented | Documented | Source ↗ | 2026-08-21 | Hosted first-party MCP connector tied to the user login and respecting Access Groups; creates Notes, Tasks and Custom Object records attributed to the acting user. Docs state write actions run without a confirmation step; no audit log documented. |
| Apollo.io | L2 · GTM & Sales Engagement | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party MCP server at mcp.apollo.io over streamable HTTP with OAuth 2.0; writes include creating contacts, adding to sequences and sending one-off emails, scoped to the authorising user’s permissions, plan tier and credit balance. |
| Clay | L2 · GTM & Sales Engagement | Official ± | Documented | Documented | Source ↗ | 2026-08-21 | First-party remote MCP server documented on Clay’s developer and university docs, plus a developer platform API/CLI covering tables, searches and workflows — external access, separate from the internal Claygent agent. |
| Outreach | L2 · GTM & Sales Engagement | Official | Documented | Documented | Source ↗ | 2026-08-21 | Contrary to the earlier finding, Outreach now publishes a first-party MCP server at api.outreach.io/mcp (OAuth 2.1, August 2026 release, Amplify add-on) with read, create and delete tools but deliberately no update/edit tools, governed by the user’s existing profile permissions. |
| ActiveCampaign | L2 · Marketing Automation | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party remote MCP server, per-account URL under Settings > Developer, explicitly supports writes: contacts, lists, tags, custom fields, automations, campaign creation and send. |
| ClickFunnels | L2 · Marketing Automation | Official | Documented | Documented | Source ↗ | 2026-08-21 | Own MCP server in technical preview at agents.myclickfunnels.com/mcp with OAuth and a selectable read-only or full-access level; full access creates and updates funnels, pages, contacts, products and more. |
| Customer.io | L2 · Marketing Automation | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party MCP server (mcp.customer.io, EU variant) exposing the Journeys UI and CDP Data Pipelines APIs with granular scopes — read, read:sensitive, write, write:live, configure — each user authenticating with their own credentials. |
| Klaviyo | L2 · Marketing Automation | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party MCP server, GA in remote-hosted form, creating and updating campaigns, flows, profiles and catalogs; scoped by private API key scopes with an optional READ_ONLY mode and Owner/Admin/Manager role requirements. |
| Semrush | L2 · Marketing Automation | Official | Documented | Documented | Source ↗ | 2026-08-21 | First-party MCP server (OAuth 2.0 or API key) but its tools are read-only by design; scoped write endpoints exist separately on the v4 Projects REST API. |
| PROS | L3 · Pricing & Packaging Strategy | None found | None found | None found | Source ↗ | 2026-08-21 | Documentation and API references sit behind the login-gated PROS Connect portal; no public developer docs or MCP announcement found. Note: PROS divested its B2B CPQ/pricing line to Conga and now positions as an airline retailing vendor. |
| Vendavo | L3 · Pricing & Packaging Strategy | None found | None found | None found | Source ↗ | 2026-08-21 | Only a login-gated documentation portal and support site; no public API/developer reference and no MCP mention. 2026 AI announcements cover an embedded pricing assistant, not external agent access. |
| Zilliant | L3 · Pricing & Packaging Strategy | Claimed, undocumented | Documented | Unclear | Source ↗ | 2026-08-21 | Press release announces an MCP server slated for Q1 2026 with no linked technical docs; the public developer docs and Customer API reference contain no MCP pages, so write scoping is unverified. |
| CaptivateIQ | L5 · Sales Compensation & Incentive Management | Third-party only | Documented | Documented | Source ↗ | 2026-08-21 | Public first-party developer site with token auth, documented rate limits and write endpoints (Data Worksheet batch update, bulk import), but no first-party MCP server — only third-party connector listings. |
| Everstage | L5 · Sales Compensation & Incentive Management | None found | None found | None found | Source ↗ | 2026-08-21 | Agent Core describes internal multi-agent orchestration with no mention of MCP, external APIs or a developer portal; no public API reference found. |
| QuotaPath | L5 · Sales Compensation & Incentive Management | None found | Documented | Documented | Source ↗ | 2026-08-21 | Public REST API covering deals, commissions, paths, teams and users with POST/PUT/PATCH/DELETE writes under workspace API tokens; no first-party MCP server anywhere in QuotaPath docs. |
| Spiff (Salesforce) | L5 · Sales Compensation & Incentive Management | None found | Documented | Documented | Source ↗ | 2026-08-21 | Dedicated Spiff developer site documents creating, updating and deleting commission objects, but no Spiff-specific MCP server or Agentforce action for commission operations — Salesforce MCP support is platform-level and does not name Spiff/ICM. |
| Clari | L4 · Sales Enablement & Revenue Intelligence | Official | Documented | Unclear | Source ↗ | 2026-08-21 | First-party API reference plus a Clari + Salesloft MCP server documented in the Salesloft help centre; the newsroom claims write-back so AI tools can act, but no published scope or permission detail confirms it, and rollout is phased through late summer 2026. |
| Gong | L4 · Sales Enablement & Revenue Intelligence | Official | Documented | Read only | Source ↗ | 2026-08-21 | First-party Gong MCP server documented in the help centre, described only in query/read terms with no documented write actions; the separate REST API does document scoped writes such as call and CRM data upload. |
| Highspot | L4 · Sales Enablement & Revenue Intelligence | Claimed, undocumented ± | Documented | Unclear | Source ↗ | 2026-08-21 | The only first-party MCP page is a product/marketing page listing capabilities with no published auth method, scopes, permission model or tool schema, so the write-sounding actions cannot be verified as documented scoped access. |
± marks a finding supported by the vendor's own indexed pages where a direct fetch of the documentation URL failed — slightly lower confidence than the rest.
How to read this
MCP server. Official means the vendor publishes and documents its own Model Context Protocol server. Claimed, undocumented means it exists in a press release or a product page with no technical documentation behind it — a distinction we think matters more than any rating on this site. Third-party only means the connector exists but the vendor didn't build it.
External API. Whether a documented public API exists that a system outside the vendor's own product can authenticate against. An in-product copilot doesn't count.
Agent write access. Whether an external agent can change something — create a record, update a deal, send a campaign — through documented, scoped, permissioned access. Reading data is table stakes; acting is the test.
A vendor scoring poorly here isn't necessarily bad software. It means that if your operating model assumes agents will do part of the commercial work, this system will need a human in the loop or an integration you build and maintain yourself. That is a cost, and it belongs in the evaluation.
Findings are point-in-time. Vendors ship. If something here is out of date or wrong, tell us at hello@agenticreadystack.com and we'll re-check and re-date the row.
The registry tells you what your tools can do. The Agentic Commercial Model benchmarks whether the commercial organisation around them is built for the same era.
