Most large mobile measurement partners (MMPs) now run an MCP server, so you can ask Claude, ChatGPT or Cursor about your attribution data. They differ on four things that matter more than the logo: whether the server is generally available, whether it can change anything or only read, how you sign in, and whether it costs extra.
This comparison uses only what each company publishes, checked on 29 October 2026, and every claim about another vendor links to its source. One disclosure: this is the Linkrunner blog, so Linkrunner is listed first. Where another MMP's server does something ours does not, we say so.
The short answer
- Generally available, hosted, with read and write tools: Linkrunner, Kochava and Tenjin.
- Open to all accounts, hosted, mostly read: AppsFlyer (on by default, though its help article is still labelled beta; one write tool, for OneLink links) and Singular (read-only on account data).
- Beta or early access: Airbridge (beta, a few write tools), Adjust (early access, added to your package through sales) and Branch (closed beta, invite only, read-only).
- No official server: AppMetrica, Trackier (Apptrove) and MyTracker. AppMetrica has community-built servers only.

"Not stated" means we could not find a price or plan on the vendor's own pages. Ask your account manager.
Linkrunner
The Linkrunner MCP server is hosted at https://mcp.linkrunner.io/mcp, over streamable HTTP. Per the Linkrunner MCP docs:
- Sign-in: OAuth in a popup, with Dynamic Client Registration and Client ID Metadata Documents, so Claude and Claude Code connect with no token to copy. ChatGPT and Codex CLI connect with a per-project token from the dashboard.
- Tools: 45 on the sign-in connection, 28 that read and 17 that make changes. Reads cover channel and campaign performance, organic installs, cohort LTV and payback, funnels, event logs, single-user attribution lookups, a deep link setup check (AASA, assetlinks.json and where a link lands in each browser) and the postback delivery log with each ad network's error codes.
- Writes: create a project, create and edit campaigns and per-ad deep links, save funnels, and manage domains, store listings, webhooks and postback event mappings. The assistant confirms before it changes anything. Campaigns, domains and projects cannot be deleted through MCP.
- Ad accounts: a token made with Read connected ad accounts adds 7 read-only tools for the Meta Marketing API and the Google Ads API, so the assistant can put Meta's own numbers beside Linkrunner's and explain the gap.
- No account needed to start: a new user can sign up, create a project from a live App Store or Google Play listing and get the SDK token in the chat.
- Price: no separate charge. It works on every Linkrunner plan, including the free 25k installs.
Where Linkrunner is behind: the server is not in the official MCP Registry yet, while AppsFlyer, Singular and Kochava are.
AppsFlyer
Per AppsFlyer's help article, AppsFlyer MCP is hosted at https://mcp.appsflyer.com/auth/mcp. It is enabled by default for every account, and an admin can turn it off.
- Tools: 24 documented, across aggregated performance, creatives, incrementality experiments, SKAN, cost and ad revenue integrations, OneLink, Smart Banners and audiences.
- Writes: one. AppsFlyer says most tools are read and query only, except
create_onelink_link, which asks for confirmation and is capped at 10 links a day per account. - Sign-in: OAuth for Claude, ChatGPT and Gemini CLI, or a bearer MCP token for Claude Code, n8n and self-hosted agents.
- Status: the help article still carries a beta label. The product news timeline shows a beta in July 2025, an open beta for all users in October 2025, and agent building marked generally available in May 2026.
- Price: not stated.
AppsFlyer documents the widest client list we found, including Microsoft 365 Copilot, Copilot Studio and Gemini Enterprise.
Adjust
Per Adjust's help page and its May 2026 announcement, Adjust MCP is hosted at https://mcp.adjust.com/mcpo and signs in with OAuth.
- Data: aggregated only, with no user-level or event-level data.
- Tools: not published. No write tools are described.
- Clients: Claude, Codex and Cursor.
- Status and price: early access. Adjust asks customers to contact their representative or sales to add it to their package.
Singular
Per Singular's help article, the server is hosted at https://mcp.singular.net/mcp-server/mcp and signs in with OAuth.
- Tools: 17 documented, for reporting, configuration (apps, data connectors, audiences, fraud rules, link domains, SKAN conversion models), troubleshooting data connectors, and SDK integration guidance.
- Writes: none on account data. One tool,
update_supported_fields, changes which fields the MCP itself returns. Data is aggregated only. - Clients: ChatGPT, Claude, Claude Code, Cursor, Gemini CLI and VS Code.
- Price: not stated.
Singular's data connector troubleshooting tools are a strong point if most of your work is cost data hygiene.
Branch
Per Branch's help center, Branch MCP is a closed beta at https://ai.branch.io/mcp, with OAuth sign-in. Access is invite only, granted per user, and read-only, scoped to the apps your account can see. Tool names are not published.
Separately, Branch published an open-source MCP server in August 2025 that you run yourself with Docker and Branch API keys. It has tools to create, update and delete deep links. The repository has not been updated since it was published.
Kochava
Per its GitHub repository, Kochava's server is hosted at https://analytics.mcp.kochava.com/mcp.
- Sign-in: an API key in an
authentication-keyheader. There is no OAuth. - Tools: about 30, for analytics and reports, funnels and LTV, and creating and updating campaigns, trackers and segments. Trackers can also be deleted. Kochava's Q3 2026 bulletin calls them read and write tools.
- No account needed to start: without a key, two tools let a user accept the terms and create a free account from the chat.
- Price: Free App Analytics, with 30-day data retention; Enterprise for unlimited retention.
Kochava is the closest to Linkrunner in scope. The main differences are sign-in (an API key you paste, against OAuth) and what the write tools cover.
Airbridge
Per Airbridge's help article, Airbridge MCP is in beta at https://mcp.airbridge.io/mcp, with OAuth sign-in.
- Tools: 38. Seven guide and SDK setup tools, 25 read-only reporting and app tools, 4 write tools (app platforms and iOS, Android and URI scheme deep link settings) and 2 tools that return app and web SDK tokens.
- Clients: Claude, Claude Code, ChatGPT and Codex.
- Status: the launch post from March 2026 planned a full release with tracking link creation and audiences for April 2026. We could not confirm that it shipped.
- Price: not stated for MCP.
Tenjin
Per Tenjin's MCP docs, the server is hosted at https://mcp.tenjin.com with OAuth, installed through Tenjin's plugin marketplace for Claude, Codex and Cursor, or by URL in any MCP client.
- Writes: read tools launched in March 2026 and write tools in July 2026: create, update and delete apps and campaigns, callback settings and site ID filters, with dry-run previews.
- Tools: no published count.
- Price: Tenjin's own comparison says MCP is included on every plan, including its free plan. That post also says AppsFlyer documents no writes, which AppsFlyer's current docs no longer support.
MMPs without an official MCP server
- AppMetrica: no official server. Community servers exist, such as appmetrica-mcp, which runs locally with your Yandex OAuth token.
- Trackier (Apptrove) and MyTracker: no server found.
Third-party wrappers exist for AppsFlyer, Singular and Adjust too. They are not the vendor's product, so check who runs them before you give one your API token.
How to choose
- You already use an MMP and want answers in Claude or ChatGPT: use your MMP's own server. AppsFlyer and Singular are generally available for reading reports today.
- You want the assistant to do setup work, not only read: look at Linkrunner, Kochava and Tenjin. Compare what the write tools cover against the jobs your team repeats, such as creating creator links or fixing postback mappings.
- Your security team will ask about sign-in: OAuth servers (Linkrunner, AppsFlyer, Adjust, Singular, Branch, Airbridge, Tenjin) never need a long-lived key pasted into a chat app. Check that write tools can be turned off for read-only users.
- You want debugging, not just reporting: check for tools that read postback delivery errors and deep link configuration. Those answer "why is Meta not getting my purchases" and "why does my link open the store", which reporting tools cannot.
Five questions to ask any MMP before you connect it:
- Is the server hosted, or do I run it?
- Which tools change my account, and can I turn them off per user?
- Does it read user-level data or aggregated reports only?
- Is it included in my plan, and is it out of beta?
- Is every change logged, and with whose name?
FAQ
Which MMPs have an MCP server? As of October 2026: Linkrunner, AppsFlyer, Singular, Kochava and Tenjin have hosted servers open to all their customers (AppsFlyer's help article still carries a beta label). Airbridge is in beta, Adjust is in early access through sales, and Branch is in a closed, invite-only beta. AppMetrica, Trackier and MyTracker have no official server.
Can I query my attribution data in ChatGPT? Yes, with an MMP whose server supports ChatGPT. Linkrunner, AppsFlyer, Singular and Airbridge document ChatGPT setup, usually through developer mode on the web.
Which MMP MCP servers can make changes, not just read? Linkrunner, Kochava and Tenjin have the broadest write tools. AppsFlyer can create OneLink links, and Airbridge can change deep link settings. Singular, Branch's beta and Adjust (as documented) are read-only.
Is MCP access free? Linkrunner and Tenjin include it on every plan, and Kochava has a free tier. Adjust adds it to your package through sales, with no public price. AppsFlyer, Singular, Airbridge and Branch do not state a price.
Do I need to install anything? No, for any of the hosted servers in the table. You add the server URL to your AI client and sign in. Branch's older open-source server and AppMetrica's community servers run on your own machine.
The practical takeaway
An MCP server is now a normal part of an MMP, so the useful question is what it lets your assistant do. If you only need reports in a chat window, your current MMP probably has you covered. If you want the assistant to create links, fix postback mappings, check deep link setup and set up a new app, compare write tools and sign-in before anything else.
To try Linkrunner's, add https://mcp.linkrunner.io/mcp to Claude and ask which of your campaigns to pause. The MCP server page lists every tool.
