Markdown vs MCP Project Memory for Coding Agents
Compare repository notes and shared project memory for coding agents. Choose by handoffs, decision history, permissions and review evidence.
Start with Markdown when one person can keep the project record current. Consider a shared project-memory service when people or agents need the same decisions, unfinished work and review evidence across sessions. The useful comparison is where your records live and how they stay current: Markdown is a format, while MCP is a way for an agent to access tools and context. A service can expose Markdown through MCP.
When repository files are enough
A small project can work well with a short agent entry point, a decision log and a handoff note. Keep commands and repository conventions near the code. Give each decision a date, rationale and source. Link the current task to its commit and test results.
Git gives those files a reviewable history. A teammate can inspect a diff, restore an earlier version and use the files without a separate service. The cost is maintenance: someone must resolve conflicting edits, retire stale guidance and make sure the next session reads the right version.
Do not buy another tool just because a session forgot something once. First check whether the missing fact was recorded and whether the agent actually loaded it.
When shared project memory helps
Consider a shared record when the same project spans several repositories, machines, agents or reviewers. Questions such as “Which decision is current?” and “Who accepted this result?” deserve explicit records when reconstructing them repeatedly becomes part of the job.
A shared service can give those records stable identities, scoped access and a common review surface. Its actual behavior matters more than the MCP label. The MCP architecture defines context exchange between hosts and servers; it does not determine how an application reasons about that context.
Compare the responsibilities
Need
Repository Markdown
Shared project-memory service
Code conventions
Keep instructions beside implementation
Link back to repository evidence
Decision history
Maintain dated records and review diffs
Check revisions, replacement history and authorship
Cross-project context
Maintain indexes and access to each repo
Check project boundaries and search scope
Delivery review
Link tests, builds and human decisions yourself
Check whether evidence and approval are separate records
Conflicting updates
Resolve Git conflicts and semantic disagreements
Verify stale-write protection and conflict behavior
Ownership
You maintain files and backups
Evaluate access, retention, portability and ongoing cost
Neither option makes an outdated assertion true. Keep intended behavior separate from observed implementation. If the specification says a checkout rejects expired quotes but a test shows acceptance, retain both facts and investigate the discrepancy.
Try one handoff before migrating
Use a disposable project or a bounded task. Save one decision, one unfinished step and one verification result. Start a fresh agent session and ask:
1.
What outcome was requested, and what is still unfinished?
2.
Which decision applies, who made it, and what evidence supports it?
3.
Which checks ran against which revision?
4.
What action is authorized next, and what still needs human review?
Then supersede the decision and repeat. A useful system should let the next session identify the current decision while preserving why the earlier one existed. Record what the agent actually retrieved; a polished summary is not enough.
Where AIMake fits
AIMake is one hosted option for teams that want shared notes, decisions, tasks and delivery proof available to their coding agents. The external harness performs the reasoning and code execution. AIMake retains records and applies its record-access and workflow rules; it does not independently establish that a test or delivery claim is correct.
Keep your repository and its implementation evidence. Evaluate the agent workflow and plans and limits if shared review and continuity are the missing pieces. If maintained files already satisfy your handoff test, keep using them.
For a repeatable evaluation, use the project-memory tool checklist. For the exact information to save between sessions, use the coding-agent handoff template.
